Firewall Manager

A modern, GNOME-integrated GUI for managing firewalld.

Overview

Firewall Manager provides a clean and intuitive interface for configuring firewalld. Built with Rust and GTK4/libadwaita, it integrates seamlessly with the GNOME desktop environment, allowing users to effortlessly manage network zones, define custom services, and toggle runtime versus permanent firewall rules.

Features

• Runtime vs Permanent Modes: Effortlessly toggle between validating temporary configurations and persisting those settings to disk.
• Contextual Change Tracking: A smart UI that tracks unsaved runtime modifications, ensuring you never accidentally lose or permanently apply rules without a prompt.
• Zone Assignments: Quickly view and switch active zones for your network interfaces.
• Service Definitions: Define, edit, and apply custom service profiles (ports and protocols) without dropping into the CLI.

Installation

Building from Source

To build and install the project locally using Flatpak, ensure you have flatpak and flatpak-builder installed, along with the standard GNOME 48 SDK.

# Clone the repository
git clone https://github.com/rodrigofilipefaria/FirewallManager.git
cd FirewallManager

# Build and install the Flatpak package
flatpak-builder build-dir com.github.rodrigofilipefaria.FirewallManager.json --force-clean
flatpak-builder --user --install --force-clean build-dir com.github.rodrigofilipefaria.FirewallManager.json

# Run the application
flatpak run com.github.rodrigofilipefaria.FirewallManager

Requirements

If running or compiling natively outside of a Flatpak container, your system will require:

• Rust toolchain (cargo, rustc)
• GTK4 / libadwaita development headers
• firewalld (must be active and serving its D-Bus endpoint)
