Is it possible you may have confused it with the GOTY edition and not the enhanced edition? From what I can tell online, no one else has been able to connect directly with the enhanced version of the game. The only reason I tried this was because I was shocked to see someone claim it was possible. It is unfortunate it isn't.
Are you familiar with Goldberg emulator? From what I can tell, it's possible to get LAN working with that. And by extension, use tunneling software. I saw one user that claims he uses that to play with his son.
