You can download an ISO image of a program called hardwall (I think) it's basically a stipped down version of Linux configured to run as a standalone firewall, all you need to do is install it on an old 386/486 or something, and do IP masquerading from that machine to the machine you surf from, (or set up DHCP) you can do that over a bit of ethernet cable one machine to the other, or by a simple 10/100 hub. Just go to freshmeat.net and look for firewalls, you'll find it :) There's also a program called Freedom, by Zero Knowledge corp, which prevents external machines accessing data from your box, it's more used to stop cookies, etc. but I think it too has a "paranoid" mode :) later jb
