You're trying to get everyone on your LAN to be able to play on Bnet? I don't think anyone has been successful with this without tons of lag. I personally don't know why there is tons of lag but I can speculate that the packets of information aren't going to the right person(s) and so there is a lot of lost packets which causes 'lag' because then the person who transmitted that information needs to continue to do so until the right person recieves it.
It's like if the person I was throwing the ball to was behind you, you keep blocking him so I have to keep throwing the ball to try to get it to him and it ends up taking a long time.

I play Starcraft on a WAN connection all the time.
Everybody on bnet plays SC on a WAN connection.
