monowall (Score 3, Interesting)

How can there be no mention yet of monowall? Its an excellent tool for simple reliable firewalling. We're running it off an old P2 class machine. The system software is on CD with our config file on a floppy. Its been completely reliable for going on a year and even this old machine happily keeps our T1 maxed out without blinking an eye. We actually replaced a failing WatchGuard box ($$) with monowall, increasing the feature set at near zero cost. The actaul hardware is a retired desktop (free) and we just added 3 PCI NICs (~$20 each). Eventually, we'll probably buy a rackmount system built for monowall, but even that only runs $500-$800.
