Protect Your Network With an Open-Source Firewall

"It's the rare IT person who doesn't sometimes run into a situation where they are helping a client or organization who has more IT needs than budget. Often it's the rule and not the exception. If you ever find yourself in a situation where you need a decently robust and full featured firewall and have a budget approaching zero, I have just the solution for you: SmoothWall Express.

"SmoothWall Express 3.0 is an open source GNU/Linux firewall which is security-hardened and freely downloadable. By design, it has minimal hardware requirements and a small footprint. It should work with nearly any Pentium class computer with at least 128MB of RAM and a hard disk with a capacity of 2GB or greater. It'll likely work with that PC you have sitting in your closet that you've been too lazy to recycle. You'll want to have at least two network cards installed for basic use, and three or more if you want to have a DMZ or incorporate a wireless network. Keep in mind though, that your firewall's reliability is limited by the hardware on which it's installed."
