Hi, I use a mac (Version 10.5.8) & I have tried to logon to Battle.net using all of them, Diablo 2 LOD, Starcraft Brood War, & Warcraft 3 Frozen Throne. All of them I am only allowed to login to the ASIA server. I have all my ports forwarded, and don't see why I can't login. I have been in contact with Lucy from Blizzard, but we still cannot figure out what is going on. We have tried;

Flushing DNS.
Reinstalling all games/patches.
Reinstalling/Reloading my entire macbook.
Making my IP static/Dynamic.
Using 4 different IP addresses at 4 different peoples houses.
Flushing Cache.
Using cocktail to clear all temporary files.

Still no use, any help would be appreciated. I have tried using a ethernet cable, as well as wireless. All my games are downloaded/fully updated from my Blizzard account.

You're not blocked from the other three realms on our end so I'd go with what the two above said.
