LogMeIn Hamachi was a pretty great way of setting up a LAN over the internet for gaming. We used to play Minecraft on it all the time in college.
Hamachi was created by Alex Pankratov.

LMI bought Hamachi in 2006 and I was involved in the development until 2009. Through that time there were no known issues with older games. Nothing was broken.
