OPNsense Manager

A native Android app to manage device-level firewall blocking on your OPNsense firewall — no web browser needed.

Features

- Device list — auto-discovered from DHCP leases with online/offline status - One-tap block/unblock — instantly adds/removes devices from a firewall alias - Blocked-only filter — filter the list to show only blocked devices - Active connections — tap any device to see its live pf state table (protocol, source, destination, bytes) - Rename devices — save friendly names stored locally on your phone - Biometric lock — optional fingerprint/face unlock to protect app access - Secure credentials — API key and secret are AES-256 encrypted on-device and masked in the UI

Requirements

- Android 8.0+ (API 26) - OPNsense firewall accessible on your local network - OPNsense API key & secret (how to create one)

Setup

1. Install the APK 2. Open the app — enter your Firewall URL, API Key, and API Secret 3. Tap Test & Connect — you'll land on the device list

How Blocking Works

The app creates a firewall alias named android_app_blocked on first block action, and a single block rule targeting that alias. Blocking a device adds its IP to the alias; unblocking removes it. Changes are applied via the OPNsense REST API immediately.

ℹ️ Note

The APK is unsigned.
