How do I figure out which ports are open behind a firewall?
I'm trying to get my BitTorrent client to work in school, but they have sealed off most of the ports. Especially ports for known apps like MSN, ICQ etc.
I could tunnel the traffic through a proxy server, but for what speed? :P
Anyone have any tips? I'm downloading stuff from sourceforge.net mirrors at 1.400kb/sec, so it would be nice to get a BitTorrent client to work here since I have my own portable HDD
Thanks for any help
Oh, btw, I'm using Slackware 9 and the Azureus BitTorrent client.
