You might want to take a look at m0n0wall too. It is based upon FreeBSD
and ipfilter. It is working very well for me on an older AMD K6/300
system. It will boot off of cdrom or a flash card. http://m0n0.ch/wall

The other thing I have noticed with some older systems is that various
unix drivers may have problems with devices on the far side of PCI
bridge chips. My system will recognize PCI cards in pci slots 1 & 2, but
not 3 & 4.

Used/refurbished thin systems from HP/IBM/Compaq are readily available
for reasonable prices. You can get a decent system that will boot from
cdrom with a 500 MHz cpu, built-in lan, decent RAM, easily for less than
$200 US.
