Firewall administration tool GUI
Platforms: Linux · Last verified September 6, 2026
Firewall Builder consists of an object-oriented GUI and a set of policy compilers for various firewall platforms. In Firewall Builder, firewall policy is a set of rules, each rule consists of abstract objects which represent real network objects and services (hosts, routers, firewalls, networks, protocols). Firewall Builder helps the user maintain a database of objects and allows policy editing using simple drag-and-drop operations.
