## Overview

The Firewall widget displays a summary of connected firewalls on a Homarr board. Currently supports OPNsense only.

## Supported Integrations

| Integration | Description |
|-------------|-------------|
| **OPNsense** | Open-source firewall & routing platform — the only supported firewall integration |

## Setup

1. Add the OPNsense integration in [[wiki/homelab/homarr-integrations|Homarr Integrations]] (set credentials, test connection)
2. Add the Firewall widget to a board — see [[wiki/homelab/homarr-boards|Homarr Boards]] for widget placement
3. Widget auto-populates from the linked integration

## Key Takeaways

- Single supported firewall: **OPNsense** (open-source, self-hosted)
- Widget requires a working OPNsense integration to display data
- Follow the standard Homarr widget-add flow (Widgets docs page)
- No additional widget-specific config beyond the integration link
