I have a computer at home in Boston. I'd like to set it up so that when I'm traveling and going online, it looks like I'm on my Boston computer. I used LogMeIn but (a) it's overkill since I don't need to access my computer and just need to use it's IP address (b) they charge a yearly fee and (c) it's slow to use the mouse and keyboard.
Is there a better way to "tunnel" through my Boston computer so it looks like I'm on that computer when I'm surfing the web on my travel laptop?
My Boston computer is a dual-boot that has XP and Ubuntu on it.
