Firewall Builder consists of a GUI and set of
policy compilers for various firewall platforms.
It helps users maintain a database of objects and
allows policy editing using simple drag-and-drop
operations. The GUI and policy compilers are
completely independent, which provides for a
consistent abstract model and the same GUI for
different firewall platforms. It currently
supports iptables, ipfilter, ipfw, OpenBSD pf,
Cisco PIX and FWSM, and Cisco routers access lists.
