I've been searching for a way to disable all public web proxies on my home network. I've searched for ways to do it on the client computer (XP Home - without 3rd party software that can be disabled) and for ways to do it with Tomato. I've read a couple of threads that mention IPchains, but I'm not getting it. Am I on the right track or is there a better way? If this is the way to go, can someone kindly point me to a primer or How-To?
