+# Getting Started with WireGuard Lab Overlay
+
+## Prerequisites
+
+### On Management Server
+
+```bash
+# Ubuntu/Debian
+sudo apt-get update
+sudo apt-get install -y \
+    terraform \
+    ansible \
+    python3-pip \
+    git \
+    docker.io \
+    docker-compose
+
+# Install Ansible collections
+ansible-galaxy collection install community.routeros
+ansible-galaxy collection install ansible.netcommon
+
+# Install Python packages
+pip3 install librouteros prometheus-client
+```
+
+### On Linux Gateways
+
+```bash
+# Ensure WireGuard is available
+sudo apt-get install -y wireguard wireguard-tools bridge-utils python3
+```
+
+### On MikroTik Routers
+
+- RouterOS 7.6 or higher
+- API access enabled
+- Admin credentials
+
+## Initial Setup
+
+### Step 1: Configure Your Lab Networks
+
+1. Copy the example configuration:
+```bash
+cd terraform
+cp terraform.tfvars.example terraform.tfvars
+```
+
+2. Edit `terraform.tfvars` with your lab networks:
+```hcl
+lab_networks = {
+  lab100 = {
+    vni           = 100
+    subnet        = "10.100.0.0/24"
+    wireguard_net = "172.16.100.0/24"
+    dhcp_mode     = "simple"  # or "failover"
+    road_warrior  = false     # Enable later
+    gateways = [
+      {
+        hostname  = "lab100-gw1"
+        type      = "linux"
+        mgmt_ip   = "192.168.1.11"  # Change to your IPs
+        api_port  = 22
+        lab_if    = "eth1"  # Interface facing lab devices
+        dhcp_role = "primary"
+      },
+      {
+        hostname  = "lab100-gw2"
+        type      = "linux"
+        mgmt_ip   = "192.168.1.12"
+        api_port  = 22
+        lab_if    = "eth1"
+        dhcp_role = "secondary"
+      }
+    ]
+  }
+}
+```
+
+### Step 2: Set Up Ansible
+
+1. Configure SSH access to your gateways:
+```bash
+ssh-copy-id admin@192.168.1.11
+ssh-copy-id admin@192.168.1.12
+```
+
+2. For MikroTik devices, create vault password:
+```bash
+cd ansible
+echo "your-vault-password" > .vault_pass
+chmod 600 .vault_pass
+```
+
+3. Encrypt MikroTik credentials:
+```bash
+ansible-vault create inventory/group_vars/mikrotik_gateways.yml
+```
+
+Add:
+```yaml
+ansible_password: your-mikrotik-password
+```
+
+### Step 3: Deploy
+
+#### Option A: Automated (Recommended)
+
+```bash
+./deploy.sh
+```
+
+#### Option B: Manual Steps
+
+```bash
+# 1. Initialize and apply Terraform
+cd terraform
+terraform init
+terraform apply
+terraform output -json > outputs.json
+
+# 2. Generate Ansible inventory
+terraform output ansible_inventory > ../ansible/inventory/hosts.yml
+
+# 3. Deploy to gateways
+cd ../ansible
+ansible-playbook -i inventory/hosts.yml playbooks/site.yml
+
+# 4. Start monitoring
+cd ../monitoring
+docker-compose up -d
+```
+
+### Step 4: Verify Deployment
+
+```bash
+# Check gateway health
+cd ansible
+ansible-playbook playbooks/health-check.yml
+
+# Check WireGuard tunnels
+ansible linux_gateways -m shell -a "wg show"
+
+# Check bridges
+ansible linux_gateways -m shell -a "ip link show type bridge"
+```
+
+## Common Tasks
+
+### Add Road Warrior Access
+
+1. Edit `terraform/terraform.tfvars`:
+```hcl
+lab_networks = {
+  lab100 = {
+    road_warrior = true  # Enable this
+    # ...
+  }
+}
+
+road_warrior_users = {
+  "jdoe" = {
+    email = "john.doe@company.com"
+    labs  = ["lab100"]
+  }
+}
+```
+
+2. Apply changes:
+```bash
+cd terraform
+terraform apply
+cd ../ansible
+ansible-playbook playbooks/generate-road-warrior.yml
+```
+
+3. Distribute configs:
+```bash
+ls ../road-warrior/generated/jdoe/
+# lab100.conf - WireGuard config file
+# lab100-qr.html - QR code for mobile devices
+```
+
+### Add New Lab Network
+
+```bash
+ansible-playbook playbooks/add-lab-network.yml
+```
+
+Follow the prompts to configure the new lab.
+
+### Emergency Shutdown
+
+```bash
+ansible-playbook playbooks/emergency-shutdown.yml
+```
+
+### Restore Lab
+
+```bash
+ansible-playbook playbooks/restore-lab.yml
+```
+
+## Monitoring
+
+Access the monitoring stack:
+
+- **Grafana**: http://your-server:3000
+  - Username: `admin`
+  - Password: `admin`
+
+- **Prometheus**: http://your-server:9090
+
+## Troubleshooting
+
+### WireGuard tunnel not coming up
+
+```bash
+# On gateway:
+sudo wg show
+sudo journalctl -u wg-quick@wg-lab100 -n 50
+
+# Check connectivity
+ping <peer-wireguard-ip>
+```
+
+### DHCP not working
+
+```bash
+# Check DHCP server
+sudo systemctl status dnsmasq
+# or for failover mode:
+sudo systemctl status isc-dhcp-server
+
+# Check leases
+sudo tail -f /var/lib/misc/dnsmasq.lab100.leases
+```
+
+### Can't reach lab devices
+
+1. Check bridge is up:
+```bash
+ip link show br-lab100
+```
+
+2. Check VXLAN interface:
+```bash
+ip -d link show vxlan100
+```
+
+3. Check FDB entries:
+```bash
+bridge fdb show br br-lab100
+```
+
+## Next Steps
+
+- Read `docs/architecture.md` for detailed architecture
+- Read `docs/operations.md` for operational procedures
+- Set up alerting in Grafana
+- Configure backup for Terraform state
+- Implement proper secret management (HashiCorp Vault)
+
+## Support
+
+For issues:
+1. Check logs: `journalctl -u wg-quick@wg-lab*`
+2. Run health check: `ansible-playbook playbooks/health-check.yml`
+3. Review documentation in `docs/`

+lab_networks = {
+  lab100 = {
+    vni           = 100
+    subnet        = "10.100.0.0/24"
+    wireguard_net = "172.16.100.0/24"
+    dhcp_mode     = "simple"
+    road_warrior  = false
+    gateways = [
+      {
+        hostname  = "lab100-linux1"
+        type      = "linux"
+        mgmt_ip   = "192.168.1.11"
+        api_port  = 22
+        lab_if    = "eth1"
+        dhcp_role = "primary"
+      },
+      {
+        hostname  = "lab100-openwrt1"
+        type      = "openwrt"      # ← OpenWrt gateway
+        mgmt_ip   = "192.168.1.14"
+        api_port  = 22
+        lab_if    = "eth1"         # Adjust to your OpenWrt interface
+        dhcp_role = "secondary"
+      }
+    ]
+  }
+}
+```
+
+Deploy:
+```bash
+./deploy.sh
+```
+
+### Testing Checklist
+
+After deploying an OpenWrt gateway:
+
+- [ ] WireGuard tunnel established: `wg show`
+- [ ] VXLAN interface up: `ip -d link show vxlan100`
+- [ ] Bridge operational: `bridge link show`
+- [ ] DHCP serving: `cat /tmp/dhcp.leases`
+- [ ] Firewall zone created: `uci show firewall | grep lab100`
+- [ ] Metrics exported: `curl http://<openwrt-ip>:9586/metrics/`
+- [ ] Can ping peer WireGuard IPs
+- [ ] Lab devices getting DHCP addresses
+
+### Known Limitations
+
+1. **DHCP Failover**: OpenWrt uses simulated failover (split ranges), not true ISC DHCP failover protocol
+2. **Resource Constraints**: Performance varies significantly based on hardware
+3. **Package Availability**: Some older/exotic architectures may lack VXLAN support
+4. **Web UI**: No LuCI integration (CLI/Ansible only)
+
+### Migration Notes
+
+If upgrading from a version without OpenWrt support:
+
+1. Update Terraform: `terraform init -upgrade`
+2. Run Terraform plan to see new inventory structure
+3. No changes needed for existing Linux/MikroTik gateways
+4. Add OpenWrt gateways incrementally
+
+### Performance Expectations
+
+| Hardware Class | WireGuard Throughput | Concurrent Devices |
+|----------------|---------------------|-------------------|
+| x86_64 (modern) | 500 Mbps - 2 Gbps | 50-100+ |
+| ARM (Cortex-A) | 100-300 Mbps | 20-50 |
+| MIPS (consumer) | 50-150 Mbps | 10-20 |
+
+### Support
+
+See:
+- `docs/openwrt-setup.md` for detailed setup instructions
+- `docs/gateway-comparison.md` for choosing gateway types
+- `docs/operations.md` for troubleshooting
+
+## Breaking Changes
+
+None - fully backward compatible with existing deployments.
+
+## Next Features (Future)
+
+- LuCI web UI integration (optional)
+- Support for OpenWrt snapshot builds
+- WiFi AP mode integration for wireless lab devices
+- Advanced QoS policies for lab networks

+# WireGuard Lab Overlay Network Architecture
+
+## Overview
+
+This solution provides automated deployment of isolated Layer 2 networks across corporate infrastructure using WireGuard and VXLAN.
+
+## Components
+
+### WireGuard Mesh
+- Full mesh topology between gateways within each lab network
+- Encrypted tunnels over corporate network
+- No routing of lab traffic through corporate infrastructure
+
+### VXLAN Overlay
+- Provides Layer 2 connectivity over WireGuard Layer 3 tunnels
+- BUM traffic replication to all peers
+- Support for up to 10 gateways per lab
+
+### Gateway Types
+- **Linux VMs**: Full-featured with ISC DHCP failover support
+- **MikroTik Routers**: Managed via RouterOS API
+
+### DHCP Modes
+- **Failover**: ISC DHCP with active-passive failover (Linux only)
+- **Simple**: dnsmasq with split address ranges
+
+### Monitoring
+- Prometheus exporters on each gateway
+- Centralized Grafana dashboards
+- Metrics: tunnel status, bandwidth, DHCP leases, bridge stats
+
+## Network Flow
+
+```
+Lab Device → Linux Bridge/MikroTik Bridge → VXLAN → WireGuard → Corporate Network → WireGuard → VXLAN → Bridge → Lab Device
+```
+
+## Security
+
+- All lab traffic encrypted via WireGuard
+- Complete isolation from corporate network
+- Road warrior clients get direct lab access
+- No inter-lab routing

+# Design Discussion and Requirements
+
+This document captures the key design decisions, requirements, and architectural discussions that shaped the WireGuard Lab Overlay Network solution.
+
+## Initial Requirements
+
+### Core Objective
+Automated deployment of a WireGuard-based overlay network that connects local lab room components at Layer 2 across the company network, without exposing lab devices to the corporate network.
+
+### Key Requirements
+1. **Layer 2 Connectivity**: Lab devices plugged into gateway routers/switches should communicate at L2 across the company network
+2. **Network Isolation**: Lab traffic must NOT have connectivity to company network
+3. **Gateway Flexibility**: Support Linux VMs, MikroTik routers, and OpenWrt devices
+4. **Scalability**: Up to 10 gateways per lab network, 10-20 independent lab networks
+5. **Automation**: Ansible or Terraform for automated deployment
+6. **Ease of Deployment**: Solution should be easily deployable
+7. **Future Requirements**: 
+   - Microsegmentation capability
+   - Road warrior access for office notebooks
+   - Central management
+   - Central monitoring/visibility
+
+### Lab Network Specifications
+- **Max gateways per lab**: 10
+- **Total lab networks**: 10-20 independent networks
+- **DHCP**: Lab devices use DHCP, each lab has own IP range
+- **Gateway types**: Linux VMs (primary), MikroTik routers, OpenWrt devices
+- **Multiple NICs**: Gateways have multiple network interfaces
+- **No VM provisioning**: Configure existing VMs/routers only
+
+## Architecture Decisions
+
+### 1. WireGuard + VXLAN Approach
+
+**Decision**: Use VXLAN over WireGuard instead of direct WireGuard bridging.
+
+**Rationale**:
+- WireGuard is L3-only natively
+- VXLAN provides true L2 extension with broadcast/multicast support
+- Clean separation of concerns:
+  - WireGuard = Encrypted L3 transport mesh
+  - VXLAN = L2 overlay with BUM traffic handling
+  - Bridge = Local device attachment
+
+**Alternative Considered**: Direct bridging of WireGuard interfaces
+- **Rejected because**: More complex, less clean architecture, harder to troubleshoot
+
+### 2. Full Mesh Topology
+
+**Decision**: All gateways within a lab network form a full WireGuard mesh.
+
+**Rationale**:
+- No single point of failure
+- Optimal path between any two gateways
+- Scales well up to 10 gateways (45 tunnels max)
+- Simpler than hub-and-spoke for small deployments
+
+**Calculation**: n gateways = n×(n-1)/2 tunnels
+- 3 gateways = 3 tunnels
+- 5 gateways = 10 tunnels
+- 10 gateways = 45 tunnels (acceptable)
+
+**Alternative Considered**: Hub-and-spoke with central gateway
+- **Rejected because**: Single point of failure, suboptimal routing, more complex failover
+
+### 3. Separate WireGuard Interface per Lab
+
+**Decision**: Each lab network gets its own WireGuard interface (wg-lab100, wg-lab200, etc.)
+
+**Rationale**:
+- Complete isolation between lab networks
+- Easier troubleshooting (can bring down one lab without affecting others)
+- Simplified microsegmentation in future
+- Clear network boundaries
+
+**Alternative Considered**: Single WireGuard interface with policy routing
+- **Rejected because**: Complex routing, harder to isolate, debugging nightmare
+
+### 4. Terraform for State, Ansible for Configuration
+
+**Decision**: Use Terraform for topology/state management, Ansible for device configuration.
+
+**Rationale**:
+
+**Terraform handles:**
+- IP address allocation (deterministic, conflict-free)
+- WireGuard key generation and tracking
+- Peer matrix calculation (combinatorial complexity)
+- Road warrior client generation
+- State persistence
+
+**Ansible handles:**
+- Platform-specific configuration (UCI vs systemd vs RouterOS)
+- Service deployment and management
+- Operational tasks (updates, health checks, emergency procedures)
+
+**Why not pure Ansible?**
+- Peer matrix calculation becomes complex Jinja2 templates
+- No built-in state for keys/IPs
+- Key generation requires custom modules
+- Change detection harder without state
+
+**Why not pure Terraform?**
+- Terraform providers for network devices are limited
+- Configuration management is Ansible's strength
+- Operational playbooks natural in Ansible
+
+### 5. DHCP Strategy
+
+**Decision**: Offer two modes - ISC DHCP failover (Linux only) and dnsmasq split-range (all platforms)
+
+**Rationale**:
+
+**ISC DHCP Failover Mode:**
+- True active-passive DHCP failover
+- Lease synchronization
+- IP address continuity across failovers
+- Linux-only (not available on MikroTik/OpenWrt)
+
+**dnsmasq Split-Range Mode:**
+- Works on all three platforms
+- Simpler configuration
+- Primary serves 10-127, Secondary serves 128-245
+- Good enough for most lab scenarios
+- No lease synchronization but acceptable for labs
+
+**Why both?**
+- Flexibility for different requirements
+- Some labs need true failover (production-like testing)
+- Other labs can use simpler approach
+
+### 6. Multi-Vendor Support
+
+**Decision**: Support Linux, MikroTik, and OpenWrt as first-class citizens.
+
+**Rationale**:
+
+**Linux (VMs):**
+- Most flexible and powerful
+- Best for primary/critical gateways
+- Full feature support (ISC DHCP failover)
+- Extensive monitoring capabilities
+
+**MikroTik:**
+- Purpose-built routing hardware
+- Cost-effective
+- Low power consumption
+- Common in network labs
+- Proven reliability
+
+**OpenWrt:**
+- Wide hardware support (x86, ARM, MIPS)
+- Repurposing existing hardware
+- Open source requirement for some environments
+- Budget-friendly option
+- Can integrate WiFi AP functionality
+
+**Implementation Strategy:**
+- Common interface across all gateway types
+- Role-based Ansible deployment
+- Gateway type determines which roles execute
+- Full interoperability (mix types in same lab)
+
+### 7. Road Warrior Support
+
+**Decision**: Build road warrior support into core architecture from start.
+
+**Rationale**:
+- Common requirement (laptops accessing lab devices)
+- Easier to design in from start than retrofit
+- IP allocation strategy accounts for it
+- WireGuard well-suited for road warrior use
+
+**Implementation**:
+- Gateways allow road warrior clients as peers
+- Clients assigned IPs from WireGuard subnet (after gateway IPs)
+- Configuration generation automated via Ansible
+- QR codes for mobile devices
+
+### 8. Monitoring Architecture
+
+**Decision**: Prometheus exporters on each gateway, centralized Grafana.
+
+**Rationale**:
+- Industry-standard monitoring stack
+- Pull-based metrics collection
+- Platform-specific exporters:
+  - Linux: Python Prometheus client
+  - MikroTik: REST API polling
+  - OpenWrt: Shell script exporter
+
+**Metrics Collected**:
+- WireGuard tunnel status (up/down)
+- Latest handshake timing
+- Rx/Tx bytes per tunnel
+- VXLAN interface statistics
+- Bridge FDB entry count
+- DHCP active lease count
+
+### 9. Firewall Isolation (OpenWrt-specific)
+
+**Decision**: Automatically create isolated firewall zones for each lab network on OpenWrt.
+
+**Rationale**:
+- OpenWrt requires explicit firewall configuration
+- Each lab needs its own zone
+- Prevent lab-to-corporate traffic
+- Allow intra-lab forwarding
+- Allow DHCP/DNS to gateway
+
+**Firewall Rules Created**:
+```
+Zone: lab100
+  Input: REJECT (except DNS/DHCP)
+  Forward: REJECT (except to same zone)
+  Output: ACCEPT
+
+Forwarding:
+  lab100 → lab100: ACCEPT
+  lab100 → lan: REJECT
+  lab100 → wan: REJECT
+```
+
+### 10. Configuration Decoupling
+
+**Decision**: Make deployment independent of existing infrastructure.
+
+**Rationale**:
+- Don't assume pre-existing Ansible inventory
+- Don't depend on existing Terraform state
+- Self-contained solution
+- Easy to integrate into existing automation later
+
+**Implementation**:
+- Fresh Terraform state
+- Self-generated Ansible inventory
+- Standalone playbooks
+- Can be integrated into larger automation framework if needed
+
+## OpenWrt Integration Discussion
+
+### Requirements for OpenWrt Support
+
+When OpenWrt support was requested, the following questions were clarified:
+
+**1. OpenWrt Version**: 23.05 or latest stable
+**2. Architectures**: x86 (Intel), ARM, potentially MIPS
+**3. Router Independence**: Should work regardless of specific router model
+**4. Management**: SSH-based first, API if beneficial
+**5. Package Management**: Auto-install missing packages
+**6. DHCP Strategy**: Pros/cons analysis requested → chose dnsmasq
+**7. Network Config**: UCI-based configuration
+**8. Firewall**: Create new zones per lab network
+**9. Monitoring**: Lightweight shell script tools
+**10. Interoperability**: Must work with Linux/MikroTik
+**11. Ansible Modules**: Best option selected (shell + UCI commands)
+**12. Storage**: Not a constraint (appropriate hardware selection)
+
+### OpenWrt Design Decisions
+
+**UCI Configuration Method**:
+- Native OpenWrt approach
+- Atomic commits
+- Rollback capability
+- CLI-friendly
+
+**Package Installation Strategy**:
+```
+Required packages:
+- wireguard-tools (WireGuard CLI)
+- kmod-wireguard (kernel module)
+- kmod-vxlan (VXLAN support)
+- ip-full (iproute2 with VXLAN)
+- tcpdump (troubleshooting)
+```
+
+**Firewall Zone Isolation**:
+- Each lab gets isolated zone
+- Prevents lab → corporate traffic
+- Allows lab → lab forwarding
+- Gateway provides DNS/DHCP
+
+**Monitoring Approach**:
+- Shell script Prometheus exporter
+- Lightweight (no Python needed)
+- Served via uhttpd on port 9586
+- Collects essential metrics
+
+## Rejected Alternatives
+
+### 1. GRE/IPIP Instead of VXLAN
+**Rejected**: Less flexible, no native L2 support, older technology
+
+### 2. OpenVPN Instead of WireGuard
+**Rejected**: Slower, more complex, heavier resource usage, older codebase
+
+### 3. Single Gateway with VLANs
+**Rejected**: Single point of failure, doesn't meet redundancy requirements
+
+### 4. Cloud-Managed Solution (Tailscale/ZeroTier)
+**Rejected**: External dependency, cost, limited control, privacy concerns
+
+### 5. Pure iptables/nftables Firewall on Linux
+**Rejected for OpenWrt**: UCI firewall is native and more maintainable
+
+### 6. LuCI Web UI Integration
+**Deferred**: CLI/Ansible-first approach, could add later as enhancement
+
+## Known Limitations and Trade-offs
+
+### 1. DHCP Failover on Non-Linux Platforms
+**Limitation**: True DHCP failover only on Linux (ISC DHCP)
+**Trade-off**: MikroTik/OpenWrt use split ranges (acceptable for labs)
+**Mitigation**: Can use Linux for critical labs requiring true failover
+
+### 2. VXLAN Performance Overhead
+**Limitation**: Double encapsulation (VXLAN + WireGuard) adds overhead
+**Trade-off**: ~5-10% throughput reduction vs single encapsulation
+**Mitigation**: Modern CPUs handle this well, acceptable for lab use
+
+### 3. Broadcast Traffic Amplification
+**Limitation**: BUM traffic replicated to all peers in mesh
+**Trade-off**: With 10 gateways, broadcast amplified 10x
+**Mitigation**: 10 gateways max limit, modern switches handle this
+
+### 4. WireGuard Key Rotation
+**Limitation**: No automatic key rotation implemented
+**Trade-off**: Manual process to regenerate and redistribute keys
+**Mitigation**: Keys stored in Terraform state, can be regenerated and redeployed
+
+### 5. No Inter-Lab Routing
+**Limitation**: Labs are completely isolated from each other
+**Trade-off**: Can't route between lab100 and lab200
+**Mitigation**: Design requirement (isolation), can add selective routing later
+
+### 6. Road Warrior Scalability
+**Limitation**: Each gateway needs peer config for each RW client
+**Trade-off**: 100 RW clients = 100 peer configs per gateway
+**Mitigation**: Acceptable for expected scale, can optimize if needed
+
+## Future Enhancements Considered
+
+### Near-Term (Feasible)
+1. **Automated key rotation** - Periodic WireGuard key regeneration
+2. **Dynamic peer discovery** - Reduce configuration for large meshes
+3. **QoS policies** - Traffic prioritization for lab networks
+4. **WiFi AP mode** - OpenWrt as wireless access point for labs
+5. **LuCI integration** - Web UI for OpenWrt management
+
+### Medium-Term (Requires Development)
+1. **Microsegmentation** - Finer-grained network isolation
+2. **Inter-lab routing** - Selective routing between specific labs
+3. **IPAM integration** - NetBox/Nautobot for IP management
+4. **Centralized logging** - Log aggregation from all gateways
+5. **Alerting rules** - Prometheus alerts for tunnel failures
+
+### Long-Term (Architectural Changes)
+1. **BGP-based routing** - For very large deployments
+2. **Multi-site support** - Gateways across multiple datacenters
+3. **IPv6 support** - Dual-stack overlay networks
+4. **Hardware offload** - WireGuard hardware acceleration
+
+## Design Principles Applied
+
+Throughout the design process, we adhered to these principles:
+
+1. **Simplicity over complexity** - Use proven technologies, avoid over-engineering
+2. **Automation first** - Everything deployable via code
+3. **Platform agnostic** - Support multiple gateway types equally
+4. **Fail-safe defaults** - Network isolation by default, explicit allowlisting
+5. **Observability** - Built-in monitoring from day one
+6. **Operational friendly** - Include operational playbooks, not just deployment
+7. **Documentation** - Comprehensive guides for all platforms
+8. **Backward compatible** - New features don't break existing deployments
+
+## Technical Debt and Known Issues
+
+### Acknowledged but Accepted
+1. **Terraform state security**: Keys stored in state (recommend remote backend with encryption)
+2. **No automated backups**: Operational playbooks include manual backup procedures
+3. **Hard-coded ports**: WireGuard listen port = 51820 + VNI (could be configurable)
+4. **No certificate-based auth**: Relies on SSH keys (acceptable for lab environments)
+
+### To Be Addressed
+1. **Error handling**: Some playbooks could have more robust error handling
+2. **Idempotency**: A few tasks could be more idempotent
+3. **Testing**: No automated integration tests (manual testing only)
+4. **Rollback**: No automated rollback on failed deployments
+
+## Conclusion
+
+This design represents a pragmatic balance between:
+- **Flexibility** (multiple platforms, multiple DHCP modes, road warrior support)
+- **Simplicity** (standard technologies, clear architecture)
+- **Automation** (minimal manual intervention)
+- **Reliability** (full mesh, redundant DHCP, monitoring)
+- **Maintainability** (good documentation, operational playbooks)
+
+The solution meets all initial requirements and provides a foundation for future enhancements while remaining production-ready today.

+
+## Mixed Deployments
+
+You can mix gateway types within a single lab network. Here's a recommended pattern:
+
+### Pattern 1: High Availability Core
+```hcl
+lab100 = {
+  gateways = [
+    { hostname = "lab100-linux1",   type = "linux",    dhcp_role = "primary" },
+    { hostname = "lab100-linux2",   type = "linux",    dhcp_role = "secondary" },
+    { hostname = "lab100-openwrt1", type = "openwrt",  dhcp_role = "backup" }
+  ]
+}
+```
+- Linux gateways provide true DHCP failover
+- OpenWrt provides additional redundancy
+
+### Pattern 2: Cost-Optimized
+```hcl
+lab200 = {
+  gateways = [
+    { hostname = "lab200-mikrotik1", type = "mikrotik", dhcp_role = "primary" },
+    { hostname = "lab200-mikrotik2", type = "mikrotik", dhcp_role = "secondary" }
+  ]
+}
+```
+- All MikroTik for consistency
+- Lower hardware costs
+- Lower power consumption
+
+### Pattern 3: Hybrid
+```hcl
+lab300 = {
+  gateways = [
+    { hostname = "lab300-linux1",    type = "linux",    dhcp_role = "primary" },
+    { hostname = "lab300-mikrotik1", type = "mikrotik", dhcp_role = "backup" },
+    { hostname = "lab300-openwrt1",  type = "openwrt",  dhcp_role = "backup" }
+  ]
+}
+```
+- Linux core for features
+- MikroTik for proven reliability
+- OpenWrt for flexibility
+
+## DHCP Mode Recommendations
+
+### ISC DHCP Failover Mode (`dhcp_mode = "failover"`)
+
+**Use when:**
+- Critical lab requiring lease continuity
+- Active-passive DHCP failover needed
+- Only Linux gateways (primary + secondary)
+
+**Configuration:**
+```hcl
+dhcp_mode = "failover"
+gateways = [
+  { type = "linux", dhcp_role = "primary" },
+  { type = "linux", dhcp_role = "secondary" },
+  { type = "...",   dhcp_role = "backup" }     # Any type for additional backup
+]
+```
+
+### Simple/Split Range Mode (`dhcp_mode = "simple"`)
+
+**Use when:**
+- Any gateway types in use
+- DHCP IP address persistence not critical
+- Simpler configuration preferred
+
+**Configuration:**
+```hcl
+dhcp_mode = "simple"
+gateways = [
+  { type = "...", dhcp_role = "primary" },     # Serves .10-.127
+  { type = "...", dhcp_role = "secondary" },   # Serves .128-.245
+  { type = "...", dhcp_role = "backup" }       # Serves full range (standby)
+]
+```
+
+## Performance Expectations
+
+### WireGuard Throughput
+
+| Gateway Type | Expected Throughput | Notes |
+|--------------|---------------------|-------|
+| Linux (modern CPU) | 2-10 Gbps | Depends on CPU/NICs |
+| MikroTik CCR | 1-5 Gbps | Varies by model |
+| MikroTik RB | 100-500 Mbps | Consumer models |
+| OpenWrt x86_64 | 500 Mbps - 2 Gbps | Hardware dependent |
+| OpenWrt ARM | 50-300 Mbps | Limited by CPU |
+
+### Recommendations by Lab Size
+
+| Lab Devices | Recommended Primary | Recommended Secondary |
+|-------------|---------------------|----------------------|
+| 1-10 | OpenWrt | OpenWrt |
+| 10-50 | MikroTik or Linux | MikroTik or OpenWrt |
+| 50-100 | Linux | Linux or MikroTik |
+| 100+ | Linux (multi-core) | Linux |
+
+## Configuration Management
+
+### Ansible Roles Per Type
+
+| Task | Linux Role | MikroTik Role | OpenWrt Role |
+|------|-----------|---------------|--------------|
+| Common Setup | `common` | `mikrotik-common` | `openwrt-common` |
+| WireGuard | `wireguard` | `mikrotik-wireguard` | `openwrt-wireguard` |
+| VXLAN | `vxlan` | `mikrotik-vxlan` | `openwrt-vxlan` |
+| Bridge | `bridge` | `mikrotik-bridge` | `openwrt-bridge` |
+| DHCP | `isc-dhcp` or `dnsmasq` | `mikrotik-dhcp` | `openwrt-dhcp` |
+| Firewall | Implicit in roles | `mikrotik-firewall` | `openwrt-firewall` |
+| Monitoring | `monitoring` | `mikrotik-monitoring` | `openwrt-monitoring` |
+
+All roles present the same logical interface - Ansible playbooks work identically regardless of gateway mix.
+
+## Monitoring Comparison
+
+### Metrics Collection
+
+**Linux:**
+- Python Prometheus exporter
+- Most detailed metrics
+- Real-time collection
+- Port 9586
+

+# OpenWrt Gateway Setup Guide
+
+## Prerequisites
+
+### OpenWrt Version
+- **Minimum**: OpenWrt 23.05 (stable)
+- **Recommended**: Latest stable release
+- **Architectures**: x86_64, ARM, MIPS supported
+
+### Hardware Requirements
+- **Flash**: Minimum 128MB (256MB+ recommended)
+- **RAM**: Minimum 128MB (256MB+ recommended)
+- **Network Interfaces**: At least 2 (one for management, one for lab devices)
+
+## Initial OpenWrt Preparation
+
+### 1. Fresh OpenWrt Installation
+
+Ensure you have a clean OpenWrt installation with network access.
+
+```bash
+# From your management workstation
+ssh root@<openwrt-ip>
+```
+
+### 2. Configure Management Network
+
+Ensure the router is reachable from your management server:
+
+```bash
+# On OpenWrt router
+uci set network.lan.ipaddr='192.168.1.21'
+uci set network.lan.netmask='255.255.255.0'
+uci commit network
+/etc/init.d/network restart
+```
+
+### 3. Install Required Packages
+
+The Ansible playbook will auto-install these, but you can pre-install:
+
+```bash
+opkg update
+opkg install wireguard-tools kmod-wireguard kmod-vxlan ip-full tcpdump
+```
+
+### 4. Enable SSH Access
+
+Ensure SSH is accessible:
+
+```bash
+# Set root password if not already set
+passwd
+
+# Enable SSH
+/etc/init.d/dropbear enable
+/etc/init.d/dropbear start
+```
+
+### 5. Configure SSH Keys (Recommended)
+
+From your management server:
+
+```bash
+ssh-copy-id root@192.168.1.21
+```
+
+## Network Interface Configuration
+
+### Identifying Interfaces
+
+List available interfaces:
+
+```bash
+# On OpenWrt
+ip link show
+```
+
+Common interface names:
+- **x86_64**: `eth0`, `eth1`, `eth2`
+- **ARM/embedded**: `lan1`, `lan2`, `wan`
+- **VLAN-aware**: `eth0.1`, `eth0.2`
+
+### Recommended Setup
+
+```
+┌──────────────────┐
+│  OpenWrt Router  │
+│                  │
+│  eth0  ───────────┼──→ Corporate Network (Management)
+│  eth1  ───────────┼──→ Lab Devices (Physical Connection)
+│                  │
+│  wg_lab100 ──────┼──→ WireGuard Overlay
+│  vxlan100 ───────┼──→ VXLAN over WireGuard
+│  br_lab100 ──────┼──→ Bridge (eth1 + vxlan100)
+└──────────────────┘
+```
+
+## Deployment via Ansible
+
+### 1. Update Terraform Configuration
+
+Edit `terraform/terraform.tfvars`:
+
+```hcl
+lab_networks = {
+  lab100 = {
+    vni           = 100
+    subnet        = "10.100.0.0/24"
+    wireguard_net = "172.16.100.0/24"
+    dhcp_mode     = "simple"
+    road_warrior  = false
+    gateways = [
+      {
+        hostname  = "lab100-openwrt1"
+        type      = "openwrt"           # Important: set to 'openwrt'
+        mgmt_ip   = "192.168.1.21"
+        api_port  = 22
+        lab_if    = "eth1"              # Interface facing lab devices
+        dhcp_role = "primary"
+      }
+    ]
+  }
+}
+```
+
+### 2. Deploy
+
+```bash
+# From project root
+./deploy.sh
+```
+
+Or manually:
+
+```bash
+cd terraform
+terraform apply
+cd ../ansible
+ansible-playbook -i inventory/hosts.yml playbooks/site.yml
+```
+
+## Verification
+
+### 1. Check WireGuard Status
+
+```bash
+# On OpenWrt router
+wg show
+```
+
+Expected output:
+```
+interface: wg_lab100
+  public key: <key>
+  private key: (hidden)
+  listening port: 51920
+
+peer: <peer-public-key>
+  endpoint: 192.168.1.11:51920
+  allowed ips: 172.16.100.1/32
+  latest handshake: 30 seconds ago
+  transfer: 5.2 KiB received, 4.8 KiB sent
+```
+
+### 2. Check VXLAN Interface
+
+```bash
+ip -d link show vxlan100
+```
+
+Expected output:
+```
+vxlan100@wg_lab100: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450
+    link/ether ... brd ff:ff:ff:ff:ff:ff
+    vxlan id 100 dev wg_lab100 dstport 4789 ...
+```
+
+### 3. Check Bridge
+
+```bash
+bridge link show | grep br_lab100
+```
+
+Expected output:
+```
+3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> master br_lab100
+4: vxlan100: <BROADCAST,MULTICAST,UP,LOWER_UP> master br_lab100
+```
+
+### 4. Check DHCP
+
+```bash
+# Show DHCP configuration
+uci show dhcp.lab100
+
+# Check active leases
+cat /tmp/dhcp.leases
+```
+
+### 5. Check Firewall
+
+```bash
+# Show firewall zones
+uci show firewall | grep lab100
+
+# Check iptables rules
+iptables -L -n -v | grep lab100
+```
+
+### 6. Test Connectivity
+
+```bash
+# Ping peer WireGuard IP
+ping 172.16.100.1
+
+# Test DHCP by connecting a lab device to eth1
+# The device should get an IP in 10.100.0.0/24
+```
+
+## Monitoring
+
+### Access Metrics
+
+The OpenWrt gateway exposes Prometheus metrics on port 9586:
+
+```bash
+# From management server
+curl http://192.168.1.21:9586/metrics/
+```
+
+Sample output:
+```
+# HELP wireguard_tunnel_up WireGuard tunnel status
+# TYPE wireguard_tunnel_up gauge
+wireguard_tunnel_up{lab="lab100",interface="wg_lab100",peer="abcd1234"} 1
+...
+```
+
+### View Logs
+
+```bash
+# On OpenWrt
+logread | grep -E 'wireguard|vxlan|lab100'
+
+# Follow logs in real-time
+logread -f | grep -E 'wireguard|vxlan|lab100'
+```
+
+## Troubleshooting
+
+### WireGuard Not Starting
+
+```bash
+# Check kernel modules
+lsmod | grep wireguard
+
+# Reload network
+/etc/init.d/network reload
+
+# Check logs
+logread | grep wireguard
+```
+
+### VXLAN Not Working
+
+```bash
+# Manually recreate VXLAN
+/etc/init.d/vxlan-lab100 restart
+
+# Check if WireGuard is up first
+ip link show wg_lab100
+```
+
+### DHCP Not Assigning IPs
+
+```bash
+# Restart dnsmasq
+/etc/init.d/dnsmasq restart
+
+# Check configuration
+uci show dhcp.lab100
+
+# Test with static IP first
+ip addr add 10.100.0.50/24 dev br_lab100
+```
+
+### Firewall Blocking Traffic
+
+```bash
+# Temporarily disable firewall for testing
+/etc/init.d/firewall stop
+
+# Check rules
+iptables -L -n -v
+
+# Re-enable
+/etc/init.d/firewall start
+```
+
+### Package Installation Failures
+
+```bash
+# Update package lists
+opkg update
+
+# Check available space
+df -h
+
+# Free up space if needed
+opkg remove <unnecessary-packages>
+```
+
+## Performance Tuning
+
+### For High-Throughput Labs
+
+```bash
+# Increase network buffers
+sysctl -w net.core.rmem_max=16777216
+sysctl -w net.core.wmem_max=16777216
+
+# Make permanent
+echo "net.core.rmem_max=16777216" >> /etc/sysctl.conf
+echo "net.core.wmem_max=16777216" >> /etc/sysctl.conf
+```
+
+### For Low-Resource Devices
+
+```bash
+# Reduce WireGuard keepalive
+uci set network.wg_lab100_peer0.persistent_keepalive='60'
+uci commit network
+
+# Limit DHCP lease time
+uci set dhcp.lab100.leasetime='1h'
+uci commit dhcp
+```
+
+## Backup and Recovery
+
+### Create Backup
+
+```bash
+# Full configuration backup
+sysupgrade -b /tmp/backup-$(date +%Y%m%d).tar.gz
+
+# Download backup
+scp root@192.168.1.21:/tmp/backup-*.tar.gz ./
+```
+
+### Restore Backup
+
+```bash
+# Upload backup
+scp backup-20250130.tar.gz root@192.168.1.21:/tmp/
+
+# Restore
+sysupgrade -r /tmp/backup-20250130.tar.gz
+```
+
+## Integration with Multi-Vendor Labs
+
+OpenWrt gateways are fully compatible with Linux and MikroTik gateways in the same lab network:
+
+```hcl
+# Example mixed gateway lab
+lab_networks = {
+  lab100 = {
+    gateways = [
+      { hostname = "gw1", type = "linux" },
+      { hostname = "rt1", type = "mikrotik" },
+      { hostname = "ap1", type = "openwrt" }  # All three work together!
+    ]
+  }
+}
+```
+
+All three gateway types:
+- ✅ Form full mesh WireGuard tunnels with each other
+- ✅ Participate in VXLAN overlay
+- ✅ Provide DHCP services (with split ranges or failover)
+- ✅ Export metrics to centralized Prometheus
+- ✅ Can be managed from same Ansible playbooks
+
+## Next Steps
+
+- Enable road warrior access: Edit `terraform.tfvars` and set `road_warrior = true`
+- Add monitoring dashboards in Grafana
+- Configure alerting for tunnel failures
+- Set up automated backups via cron
+
+## Support
+
+For OpenWrt-specific issues:
+- OpenWrt documentation: https://openwrt.org/docs
+- Check `/var/log/messages` for system logs
+- Use `logread -f` for real-time debugging
+- Run health check: `ansible-playbook playbooks/health-check.yml`

+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to

+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must

+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *

+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a

+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
