Titan Quest and Hamachi

Does anybody know how to get Titan Quest Immortal Throne to work over hamachi, or more specifically is it possible to get the latest version TQIT to work over the latest version of hamachi? I've had a search around and come up with dead ends on this. I've tried putting aliases on to so everyone is on the same ip range and that doesn't seem to work. This isn't particularly important to me because I've got port forwarding setup up for the game anyway but if anyone has any words of wisdom they are greatly appreciated.

Cheers
