Firewall Builder 3.0.7

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 and Cisco PIX.
Firewall Builder allows for management of multiple firewalls using the same network object database. Change made to an object is immediately reflected in the policy of all firewalls using this object. Administrator only needs to recompile and install policies on actual firewall machines.

In Firewall Builder, administrator works with an abstraction of firewall policy and NAT rules; software effectively "hides" specifics of particular target firewall platform and helps administrator focus on implementation of security policy. Backend software components, or policy compilers, can deduct many parameters of policy rules using information available through network and service objects and therefore generate fairly complex code for the target firewall, thus relieving administrator from having to remember all its details and limitations. Policy compilers can also run sanity checks on firewall rules and make sure typical errors are caught before generated policy is deployed.
