Can you host on battle.net without others on your home lan joining? If so, is everyone on you home lan using a unique cd-key? I'm not sure of how blizzard and battle.net view multiple players from 1 ip with the host on the same ip, but if all the cd-keys are not unique I doubt they would allow that to work. When I get home tonight I'll try what you are attempting and follow up on this post if i find anything helpful.
