Firewall Builder
by lecyborg
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. Technical summary of features supported by the policy compilers for all platforms can be found in the section "Modules" (see menu on the left).
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.

This page shall be easy to read and understand to reduce the manual analysis time.
This page containts statistics on packets and links to more detailled information on a given host, port, domain and so on.
