I have a lot of down time at my job, so I connect my laptop to my works internet through an ethernet cord to help kill time. Lately, my work has installed an internet firewall so now I can't access some of my favorite sites ie facebook. Is there a something I can do that would let me access my computer at home from work and use the internet from that computer so that the internet wouldn't be restricted? I've heard of VPN's and VNC's, but I'm not familiar how they work. My home computer uses Windows XP and my laptop is Windows 7. I'm only looking for ideas that have actually been tested out and work, not just suggestions.
