Firewall Builder is a firewall configuration and management GUI that supports configuring a wide range of firewalls from a single application. Supported firewalls include Linux iptables, BSD pf, Cisco ASA/PIX, Cisco router access lists and many more. Import of existing iptables configurations was greatly improved in the recently released Firewall Builder V4.2. Features like object de-duplication and expanded rules recognition make it even easier to get started using Firewall Builder to manage your iptables configurations.
