Hi everyone... I've installed service pack 2 recently and disable the security center (firewall, antivirus and update) But when i try to download a torrent file using bit tornado or any other bittorrent client, it say that my computer is behind a firewall... Still, I have the chance of having a second computer with only SP1 installed and if I download the same file, everything is OK. This cause problem, because downloading a torrent file behind a firewall can drop the speed a lot !!! (going from 230 kb/s to about max 25- 35 kb/s) Anyone got a fix for that?
