P2P Application that goes through firewalls

[d_unbeliever]

Are there any P2P Application that goes through school firewalls (squid)...i don't want to use any tunneling program or circumventor since its either they are quite slow or u need to subscribe (don't have the money) to use them...

hope you will help me with this guys...been looking for solution for eternity....

"Go through" a firewall? Well ...... no. Go around ... surely theyre not blocking ALL ports. Use a program that lets you select the port to use.
