m0n0wall <http://m0n0.ch/wall/> is the probably easiest firewall package 
to use. It is FreeBSD based with a web interface to manage it. You can 
put it on any number of hardware configurations, including an older PC 
with two network cards. I've been using it for a couple of years now 
with no problems. It forwards logs to an internal syslog server on my 
home network.
