I heard about IPcop. It can be classified as hardware-based firewall, right? Anyway, we have an old P3 and I equipped it with 2 LAN cards. I was able to run IPcop but I wasn't able to connect to the net, so I shelved the project for the moment. You guys using IPcop? Is it worth the additional hardware and maintenance cost (like electricity)? I'm trying to protect a network of 60 computers.
