Firewall Builder consists of an object-oriented GUI and a set of policy compilers for various firewall platforms. In Firewall Builder, a firewall policy is a set of rules; each rule consists of abstract objects that represent real network objects and services (hosts, routers, firewalls, networks, protocols). Firewall Builder helps users maintain a database of objects and allows policy editing using simple drag-and-drop operations. Preferences and object databases are stored in XML format.
We support policy compiler for the popular free firewall engine iptables, ipfilter and OpenBSD PF.
Here is one to watch.
