Hi, I have the same probs - the univerity blocks the port. I htink the only workaround is to set up an linux-server on both sides of the firewall, so that you can start to tunnel the ports linuxserver1 to linuxserver2 over the http or ftp ports. they can't cloce these ports.
The problem ist to find an linuxserver in the www to which you have full access.
