I use CC proxy. I don't do anything special at home. My IP address shows as my home IP when I'm at work. My home connection is essentially just a middle-man.

I'll get more specific on the settings when I get home, if you want me to. I set it up ages ago, so I don't really remember how to set it up, but I can probably figure it out easy enough. I remember it being a really simple program to set up at any rate.
