Smoothwall Express is an open source firewall distribution based on the GNU/Linux operating system. Designed for ease of use, SmoothWall Express is configured via a web-based GUI and requires absolutely no knowledge of Linux to install or use. SmoothWall Express enables you to easily build a firewall to securely connect a network of computers to the Internet.
The most obvious new features in Smoothwall Express 3, are the updated linux kernel (from 2.4 in Smoothwall Express 2) to 2.6 which gives better support for network cards and todays hardware, and of course the Smoothwall web based interface has a slick, new, expertly designed theme.
