How to connect two computers on a different location faking LAN?

Hey ,guys

I friend of mine downloaded Bordelands. This game has the option to LAN between two computers. Now we want to create a LAN private network between two computer at a completely different location. This way Windows will think we are LANing, but we are on different addresses. We have heard of a program wich (could possibly) do that, Hamachi, but we don’t know how it works or if it is actually possible to do such thing.
