Firewall Builder is multi-platform firewall configuration and management tool. It consists of a GUI and set of policy compilers for various firewall platforms. Firewall Builder uses object-oriented approach, it helps administrator maintain a database of network objects and allows policy editing using simple drag-and-drop operations. Firewall Builder currently supports iptables, ipfilter, OpenBSD PF as well as Cisco PIX and Cisco IOS extended access lists. Being truly vendor-neutral, Firewall Builder can generate configuration file for any supported target firewall platform from the same policy created in its GUI. This provides for both consistent policy management solution for heterogeneous environments and possible migration path.
