**Status**: Production Stable | **License**: MIT | **Version**: [![v3.11.8](https://img.shields.io/badge/version-3.11.8-blue)](https://github.com/agit8or1/OPNMGR/releases) | **Agent**: v1.4.0

A comprehensive web-based management platform for centralized monitoring, configuration, and maintenance of OPNsense firewalls.

If you find OPNManager useful, please consider giving it a star on GitHub — it helps others discover the project!

### New in v3.11 — Complete UI Redesign

OPNManager v3.11 features a ground-up UI redesign inspired by Datadog and Grafana:

- **Collapsible icon sidebar** — slim 72px rail that expands on hover, pin to keep open
- **Firewall health grid dashboard** — at-a-glance health cards for every firewall with status dots, health bars, uptime, and last checkin
- **Dark + Light themes** — system-preference aware with manual toggle, consistent across all pages
- **KPI metric strip** — compact pills showing total firewalls, online/offline counts, updates needed, and average health score
- **Professional design system** — 1,600+ lines of CSS with custom properties, no more inline styles
- **Security hardening** (v3.10) — 25+ endpoints secured with authentication, CSRF on 19+ forms, dependency updates

## System Requirements

### Server Requirements
- **OS**: Ubuntu 22.04 LTS or newer
- **PHP**: 8.0 or higher
- **MySQL/MariaDB**: 8.0+ / 10.6+
- **Web Server**: Apache 2.4+ or Nginx 1.18+
- **Disk Space**: Minimum 10GB (20GB+ recommended for backups)
- **Memory**: Minimum 2GB RAM (4GB+ recommended)

### Managed Firewalls
- **OPNsense**: 20.7+ (tested up to 25.7.x)
- **FreeBSD**: 13.x or 14.x
- **Connectivity**: Outbound HTTPS (443) access to manager server

---

## Quick Start

### 1. Server Installation

```bash
# Clone the repository
cd /var/www
git clone https://github.com/agit8or1/OPNMGR.git opnsense
cd /var/www/opnsense

# Install PHP dependencies
composer install --no-dev

# Import the database schema
# This creates the `opnsense_fw` database, all tables, and the reference data.
mysql -u root -p < database/schema.sql

# Create the application database user
mysql -u root -p -e "
  CREATE USER 'opnsense_user'@'localhost' IDENTIFIED BY 'your-secure-password';
  GRANT ALL PRIVILEGES ON opnsense_fw.* TO 'opnsense_user'@'localhost';
  FLUSH PRIVILEGES;"

# Configure the application
cp .env.example .env
# Edit .env and set at minimum DB_HOST, DB_NAME, DB_USER, DB_PASS and APP_URL
chmod 640 .env

# Create the first administrator account
php scripts/create_admin.php

# Set proper permissions
chown -R www-data:www-data /var/www/opnsense
chmod 755 /var/www/opnsense

# Configure Apache virtual host and reload
a2ensite opnmanager
systemctl reload apache2
```

> **Note:** the schema is safe to re-import — every statement is idempotent.
> To regenerate it from an existing installation, run `scripts/generate_schema.sh`.

### 2. Firewall Enrollment

#### Option A: Quick Enrollment (Recommended)

1. Log into OPNManager web interface
2. Navigate to **Firewalls > Add Firewall**
3. Generate an enrollment key
4. On the OPNsense firewall, run the one-liner install command shown on the page

#### Option B: Manual Plugin Installation

```bash
# On the OPNsense firewall, install the agent plugin:
fetch -o - https://<your-opnmgr-server>/downloads/plugins/install_opnmanager_agent.sh | sh
```

Then configure the agent via the OPNsense web GUI under **Services > OPNManager Agent**.

### 3. Agent Plugin

The OPNManager agent installs as a native OPNsense plugin:

- **Plugin location**: `/usr/local/opnsense/scripts/OPNsense/OPNManagerAgent/agent.sh`
- **Configuration**: Via OPNsense GUI (Services > OPNManager Agent)
- **Service management**: `service opnmanager_agent start|stop|restart`
- **Logs**: `/var/log/opnmanager_agent.log`
- **Auto-update**: Agent checks for updates on each check-in and self-updates

---

## Configuration

### Agent Check-in

The agent checks in every 2 minutes by default. On each check-in, it reports:
- System stats (CPU, memory, disk)
- Network interface status and traffic counters
- Latency measurements
- OPNsense version and update availability
- Pending command results

### Traffic Counter Intelligence

The agent uses the best available counter source:
- **Link layer** (default): Captures all traffic including forwarded/NAT
- **pf counters** (fallback): Used when Link-layer counters are frozen (common with virtio_net on VPS)
- **IP layer** (last resort): Per-address traffic only

---

## Security

### Authentication
- Secure password hashing (PHP `password_hash`)
- Session management with CSRF protection
- Login attempt logging

### Agent Communication
- HTTPS-only agent check-ins
- Hardware ID-based firewall identification
- Base64-encoded command payloads
- PID file locking prevents duplicate agents

### Secure Connections
- On-demand SSH reverse tunnels (dynamic port allocation 8100-8200)
- No exposed firewall ports required
- Automatic tunnel session cleanup

---

## Troubleshooting

### Agent Not Checking In

```bash
# On the OPNsense firewall:
service opnmanager_agent status
tail -20 /var/log/opnmanager_agent.log
```

### Network Data Shows Incorrect Values

- Ensure agent is v1.5.6+ (supports pf counter fallback for virtio_net)
- Check agent log for "Link layer counter frozen" messages
- Traffic data accumulates over time; new installations need ~24h for full graphs
