A great start is to search whttp://sourceforge.net/ for firewalls.

There are quite a few CD ISO distributions that can be easily installed from the CD to a hard drive, run from the CD ROM and etc.

Some of the more popular are:


You'll need two network interface cards. All the distros are free OPenSOurce and have good documentation and great user forums for help.

Hope this got you started!

I'll add a couple more options:

m0n0wall (http://m0n0.ch/wall/) - Embedded software firewall package based on FreeBSD
pfSense (http://www.pfsense.com/) - Based on m0n0wall, but uses OpenBSD's pf as for it's firewall functions, and adds feature rich routing functionality, my personal favorite

All of the ones mentioned are hard drive -based, but there are also live-CD based ones that don't require a hard drive installation (nor a hard drive at all), such as Devil-Linux (http://www.devil-linux.org/). There are also commercial options, such as Astaro (http://www.astaro.com/) and ClarkConnect (http://www.clarkconnect.com/).
