I'm looking for a solution from MP pro gamers. Me and my mates play via Hamachi, and I created the network. My Diablo 2 copy sees and uses the Hamachi-provided IP-address, so I can host games. But my mate's copies don't see their Hamachi IP address, so they can't host games. They tried to restart Hamachi, D2 and computers, but they didn't succeed. So how is that Diablo 2 does not see the Hamachi network on a Windows 7 computer?
