How to install and Configure Smoothwall Express 3 Firewall

The SmoothWall GPL project was founded in the summer of 2000 by Lawrence Manning (Principle Code Author) and Richard Morrell (Project Manager). Their goal was to create a Linux distribution that could convert a redundant PC into a hardened internet firewall device. With help from other early contributors; John Faulty and Tom Ellils, the first SmoothWall Firewall was posted to sourceforge.net at the end of August 2000.

The project was immediately popular and grew rapidly. Within weeks, thousand of copies had been downloaded and SmoothWall was appearing regularly on magazine cover CDs in the UK and overseas. Many more developers joined the team and new versions were released almost weekly, incorporating new features based on software contributions from all round the world.
