gShield (formerly Godot's Modified Modular Firewall), is an aggressive, modular, ipchains-based firewall script. Features include: easy configuration through a BSD-style configuration file, optional IPmasq support, TCPwrapper-like funtionality for service access, and extremely restrictive defaults. It hopes to make administrating a comprehensive firewall easier, as well as offering robust protection.
