possible to pass through server fire wall?

Is it possible to break through the fire wall and have the normal internet environment back again?

I'm having problems like
1. can't receive stuff with msn messenger
2. can't access AIM
3. torrent not working
4. bad msn messenger connection

oh and the internet is connected through lan lol

WTFWTFWTF I feel like going out and beating someone

somebody help

wtf, im behind a firewall and i can send/receive msn filesends with no ports open. and aim shouldnt be blocked even if ports are closed.

torrents is a normal ports issue though... hmmm, sounds like there blocking inbound AND outbound traffic at the gateway, unless its your gateway/router your probably fucked
