Gameranger Connection Problem

[[LOT]rundown 3]

"Your internet connection is behind a Port-Restricted Cone NAT Router that may prevent you from connecting to some players in peer-peer games."

This is the message I get when I either host or join a game when I am on the internet using gameranger at school. Does anyone know how to fix this? I can join and host games but when I do I lagg so much that it is unplayable so something must be done to fix it. I am on a university network.

Unfortunately I'm on a school network so I don't have access to port forwarding.
