Last night I went along to the Herts LUG again. Not so many there this time. Actually there were far more computers than people as someone had brought along several very old PCs to see what could be done with them. We actually managed to get enough bits to almost build a Smoothwall firewall. It was only a P200 with 32MB, but it seems that is enough. The biggest problem was finding a CD drive that would read a CDR. I'm not sure I need a dedicated PC as a firewall. I have a router that can do what I need and it's cheaper to have that on all the time than a PC. It's also silent. It just means I always have lots of flashing lights in the study with that and the cable modem.
