FirewallFabrik is a graphical firewall policy management tool and modern successor to Firewall Builder.
Its Qt 6 interface provides centralised policy design for multiple Linux firewalls, with support for both iptables and nftables.
Administrators create reusable objects representing hosts, networks, services and interfaces, then arrange them into firewall rules. FirewallFabrik compiles these policies into deployment-ready configurations that can be installed manually, through automation tools, or with its built-in SSH installer.
This is free and open source software.
Key Features
- Manages iptables and nftables policies from a unified Qt 6 interface.
- Maintains objects, rules and firewall definitions in a central policy database.
- Supports reusable hosts, networks, services, interfaces and object groups.
- Generates deterministic, human-readable firewall configurations.
- Stores policies in a version-control-friendly YAML format.
- Imports existing Firewall Builder XML policy files.
- Supports dual-stack IPv4 and IPv6 firewall policies.
- Provides NAT, custom chains, clustering and routing configuration.
- Detects problems such as rule shadowing during compilation.
- Includes search, search and replace, and full undo and redo history.
- Deploys policies to individual or multiple firewalls over SSH.
- Integrates with Ansible, CI/CD pipelines and other automation systems.
