Technical Specification: Modular NetBird Suite for OPNsense

1. Executive Summary

1.1 Project Overview

This project defines the architecture for a fully modular NetBird VPN integration on OPNsense. To maximize scalability and adhere to the "separation of concerns" principle, the ecosystem is divided into three distinct plugins:

• os-netbird-management (The Controller): The primary interface and brain. It hosts the Management Service and the Dashboard.
• os-netbird-signal (The Negotiator): A dedicated plugin for the Signal Service.
• os-netbird-relay (The Tunnel): A standalone plugin for the Relay Service.

1.2 Dependency Graph

To ensure a seamless user experience, we utilize the FreeBSD Ports dependency system:

• os-netbird-management depends on os-netbird-signal.
  • Rationale: A Management server cannot function effectively without a Signal server. Installing the Management plugin will automatically pull in the Signal plugin.
• os-netbird-relay has NO dependencies.
  • Rationale: Relays are often deployed on edge nodes (DMZ) that do not need the full management stack.

2. AGENT CONFIGURATION (SKILLS.md)

To be provided to the OpenCode Agent before starting the session.

AGENT SKILLS & TOOLS

You are an expert OPNsense Plugin Developer working in a hybrid environment. You must use the following methods to interact with the target system.

Environment

• Host (Local): Linux Development Workstation. Stores source code.
• Target (Remote): OPNsense VM (FreeBSD 13/14). IP: 192.168.122.225. User: root.
• Hypervisor: Libvirt/KVM running on Host.
• Authentication: There is a file in the local directory named 'opnsense_vm', use that for ssh auth, but if that fails, the root password is 'arocna3'

Skill: Remote Command Execution

When asked to "Run command X on target", use SSH:
ssh -o StrictHostKeyChecking=no root@192.168.122.225 -i /home/andrew/home_devices/opnsense_netbird/opnsense_vm "sh -c 'COMMAND'")

Skill: File Deployment

When asked to "Deploy file X to Y", use SCP:
scp -o StrictHostKeyChecking=no./home/andrew/home_devices/opnsense_netbird/known -i /home/andrew/home_devices/opnsense_netbird/opnsense_vm root@192.168.122.225:/remote/path/file

Skill: Service Management

• Reload Configd: ssh... "service configd restart"
• Reload Templates: ssh... "configctl template reload OPNsense/NetBird"
• Restart Service: ssh... "service netbird_mgmt restart"

Skill: Visual Verification (Puppeteer)

You have access to a local Node.js environment with puppeteer installed. Use this to take screenshots of the OPNsense Web UI to verify your work.

3. Technical Architecture

3.1 Plugin A: The Signal Service (os-netbird-signal)

• Role: Facilitates P2P handshake exchange between peers.
• Service Logic:
  • Local Mode: Bound to 127.0.0.1:10000, meant for Caddy proxying.
  • Public Mode: Bound to 0.0.0.0:10000 with its own TLS certs.
• Files: /usr/local/etc/rc.d/netbird_signal, /usr/local/etc/netbird/signal.json.

3.2 Plugin B: The Management Suite (os-netbird-management)

• Role: Orchestrator, User Interface, Identity Provider Interface.
• Integration Points:
  • Caddy: Configures the Reverse Proxy to route traffic to the Dashboard, Management API, and the local Signal API (provided by the dependency).
  • Certificates: Extracts certificates from the OPNsense Trust Store.
  • DNS: Syncs Unbound overrides to the Management network routes.

3.3 Plugin C: The Relay Service (os-netbird-relay)

• Role: Relays traffic for peers behind difficult NATs.
• Configuration: Minimal inputs (Management URL, Shared Secret).
• Firewall: Automatically manages the large UDP port range required for TURN functionality.

Dashboard Enablement (February 2026)

Overview

The NetBird Management plugin now includes support for the official NetBird Dashboard - a modern, feature-rich web interface for managing your NetBird network. The dashboard can be easily installed, configured, and updated directly from the OPNsense web UI.

Features

• One-Click Installation: Download and install the official dashboard from GitHub releases
• Automatic Updates: Update to the latest version with automatic backup creation
• Flexible Serving: Choose between static file serving (Caddy/Nginx) or built-in PHP server
• SSL/TLS Support: Configure SSL certificates for secure dashboard access
• Reverse Proxy Integration: Automatically configure your preferred reverse proxy
• Backup Management: Automatic backups before updates with restore capability
• Centralized Logging: All dashboard operations logged for troubleshooting

Enabling the Dashboard

1. Navigate to Services > NetBird > Management
2. Click on the Dashboard tab
3. Check the "Enable Official Dashboard" checkbox
4. Click "Install Dashboard" button
5. Wait for the download and installation to complete (progress shown)
6. Once installed, click "Open Official Dashboard" to access it

Dashboard Configuration

Navigate to the Dashboard Config tab to customize settings:

Serving Method

• Static Files (Caddy/Nginx) [Recommended]: Serve dashboard files directly through your reverse proxy. Best performance for production use.
• Built-in PHP Server: Use PHP's built-in server. Useful for testing or when reverse proxy is not available.

Network Configuration

• Listen Address: IP address to bind to (default: 127.0.0.1)
• Listen Port: Port number (default: random port above 10000, or specify manually)
• SSL Certificate: Select from OPNsense certificate store for HTTPS access

Management API

• API Endpoint: Auto-detected from management configuration. Modify if your setup requires a different endpoint.

Reverse Proxy

• Configure Reverse Proxy: Enable to automatically add dashboard to your reverse proxy
• Domain: The domain name for accessing the dashboard (e.g., dashboard.example.com)
• Path: URL path for the dashboard (default: /ui/netbird/dashboard)

Updating the Dashboard

1. Go to Dashboard Config tab
2. Click "Update Dashboard" button
3. System will automatically:
   • Create a backup of current installation
   • Download the latest release from GitHub
   • Extract and install new version
   • Preserve your configuration
4. Click "Open Official Dashboard" to verify the update

Note: The system keeps the last 5 backups automatically. Older backups are cleaned up to save space.

Backup Management

The Dashboard Config tab includes a backup management section:

• View Backups: See all available backups with date, version, and size
• Restore: Click "Restore" to revert to a previous version
• Delete: Remove old backups to free up space

Important: Always create a backup before major changes or updates.

Troubleshooting Dashboard

Installation Fails

1. Check the Logs tab for detailed error messages
2. Verify internet connectivity (GitHub API access required)
3. Check disk space: df -h /usr/local/www/
4. View installation log: /var/log/netbird/dashboard_installer.log

Dashboard Won't Load

1. Verify dashboard is installed: Check if /usr/local/www/netbird-dashboard/ exists
2. Check if service is running (for built-in server): service netbird_dashboard status
3. Verify firewall rules allow access to the port
4. Check reverse proxy configuration if using one

Update Issues

1. Ensure backup directory is writable: ls -la /var/backups/
2. Check GitHub API rate limits (cached for 1 hour)
3. Manually clear cache: rm /var/cache/netbird_dashboard_release.json

Multi-Reverse-Proxy Support (February 2026)

Overview

The NetBird Management plugin now supports multiple reverse proxy options: Caddy, Nginx, and HAProxy. The system can auto-detect installed proxies or you can manually select your preferred option.

Supported Proxies

Proxy	Auto-Detection	Static Files	Built-in Server	Notes
Caddy	✅ Yes	✅ Yes	✅ Yes	Recommended for automatic HTTPS
Nginx	✅ Yes	✅ Yes	✅ Yes	Good for high-traffic setups
HAProxy	✅ Yes	✅ Yes	✅ Yes	Best for load balancing
Direct	N/A	N/A	N/A	No proxy (not recommended)

Configuration

1. Navigate to Services > NetBird > Management
2. Click on the Settings tab
3. Select Reverse Proxy option:
   • Auto-detect (Recommended): Uses first available enabled proxy
   • Caddy/Nginx/HAProxy: Force specific proxy
   • Direct Access: No reverse proxy (warning: not recommended)

How It Works

Auto-Detection Priority:

1. Check if Caddy is installed and enabled
2. Check if Nginx is installed and enabled
3. Check if HAProxy is installed and enabled
4. If none found, recommend Caddy installation

Configuration on Save: When you save management settings with a public domain configured:

1. System detects which proxy to use
2. Adds reverse proxy rules for:
   • /signal → 127.0.0.1:10000 (Signal Service)
   • /api → 127.0.0.1:33073 (Management API)
   • /ui/netbird/dashboard → Dashboard files (if enabled)
3. Automatically reloads the proxy service
4. Shows success/error messages

Static File Serving

For the dashboard, when using Static Files serving method:

• Caddy/Nginx serve files directly from /usr/local/www/netbird-dashboard/
• Uses try_files directive for proper SPA (Single Page Application) routing
• React Router handles client-side navigation correctly

Manual Proxy Configuration

If you prefer to configure the proxy manually, here are example configurations:

Caddy:

dashboard.example.com {
    reverse_proxy /signal 127.0.0.1:10000
    reverse_proxy /api 127.0.0.1:33073
    reverse_proxy /ui/netbird/dashboard /usr/local/www/netbird-dashboard
}

Nginx:

server {
    listen 443 ssl;
    server_name dashboard.example.com;
    
    location /signal {
        proxy_pass http://127.0.0.1:10000;
    }
    
    location /api {
        proxy_pass http://127.0.0.1:33073;
    }
    
    location /ui/netbird/dashboard {
        alias /usr/local/www/netbird-dashboard;
        try_files $uri $uri/ /index.html;
    }
}

Firewall Rules (February 2026)

Automatic Firewall Rule Management

All three NetBird plugins include automatic firewall rule management through OPNsense's plugins.inc.d hook system. Rules are dynamically created when services are enabled and removed when disabled.

Rule Creation Behavior

Signal Service (os-netbird-signal)

• File: etc/inc/plugins.inc.d/netbird_signal.inc
• Rule Logic:
  • Checks if service is enabled: $mdl->general->enabled
  • Only creates rules if not binding to localhost (127.0.0.1)
  • In localhost mode (default): No firewall rules needed (operates behind Caddy proxy)
  • In public mode: Creates TCP pass rule on WAN for port 10000
• Default: Localhost mode, no external firewall rules

Management Service (os-netbird-management)

• File: etc/inc/plugins.inc.d/netbird.inc
• Rule Logic:
  • Checks if service is enabled: $mdl->general->enabled
  • Only creates rules when service is enabled
  • Creates TCP pass rule on LAN for port 33073 (Management API)
• Port: TCP 33073
• Interface: LAN (configurable)

Relay Service (os-netbird-relay)

• File: etc/inc/plugins.inc.d/netbird_relay.inc
• Rule Logic:
  • Checks if service is enabled: $mdl->general->enabled
  • Reads ports from configuration model
  • Creates rules dynamically based on configured ports
• Ports:
  • TCP 33080 (Relay API)
  • UDP 49152-65535 (TURN relay ports, configurable)
• Interface: WAN (for external peer connections)

Dashboard Service (Built-in Server)

• File: usr/local/etc/rc.d/netbird_dashboard
• Rule Logic:
  • Only applies when using built-in PHP server mode
  • Creates TCP pass rule for configured listen port
  • Rules managed by standard OPNsense service framework
• Port: Configurable (random >10000 by default)
• Interface: LAN (127.0.0.1 by default)

Implementation Details

Hook Registration

// Each plugin registers a firewall hook function
function netbird_signal_firewall($fw) { ... }
function netbird_firewall($fw) { ... }
function netbird_relay_firewall($fw) { ... }

Rule Registration

$fw->registerFilterRule(1, array(
    'type' => 'pass',
    'interface' => 'wan',
    'protocol' => 'tcp',
    'from' => 'any',
    'to' => '(self)',
    'to_port' => '33080',
    'descr' => 'NetBird Relay API',
    'log' => false
), null);

Configuration Check

$mdl = new \OPNsense\NetBird\Relay();
if ((string)$mdl->general->enabled !== '1') {
    return; // Skip rule creation if disabled
}

Security Considerations

1. Signal Service: Default localhost binding provides security through isolation
2. Management Service: LAN-only by default, can be changed to WAN if needed
3. Relay Service: WAN-facing by design to allow external peer connections
4. Dashboard Service: Localhost-only by default, reverse proxy recommended for external access
5. All Rules: Use 'pass' action with minimal logging to reduce log noise

Verification Commands

# Check firewall rules
pfctl -sr | grep netbird

# Check specific service rules
pfctl -sr | grep 33080  # Relay
pfctl -sr | grep 33073  # Management
pfctl -sr | grep 10000  # Signal (if in public mode)

# Reload firewall rules
service configd restart

Symptom: Dashboard shows "Cannot connect to API"

Solutions:

1. Check management service: service netbird_management status
2. Verify API endpoint: curl http://127.0.0.1:33073/api/peers
3. Check API endpoint configuration in Dashboard Config tab
4. Review management logs: tail -50 /var/log/netbird/management.log

Backup Restore Fails

Symptom: "Restore failed" error message

Solutions:

1. Verify backup exists: ls -la /var/backups/netbird-dashboard/
2. Check permissions: ls -la /var/backups/
3. Ensure target directory is writable: ls -la /usr/local/www/
4. Try manual restore from command line

Getting Help

If issues persist:

1. Check Logs First: Always start with /var/log/netbird/ logs
2. Verify Services: service netbird_* status for all services
3. Test Connectivity: sockstat -4l | grep netbird to verify ports
4. Review Configuration: Check all settings in web UI
5. Restart Services: Sometimes a full restart helps:

   service netbird_management restart
   service netbird_signal restart
   service netbird_relay restart
   service configd restart
   

Debug Mode

Enable debug logging by modifying log level in service scripts or adding verbose flags to configuration.
