Trying to set up a server from college network

So this is actually my friend that is trying to set up a server and he is on campus. I am not and would like to connect but no matter what we try the server does not show up at all. Running port scans constantly shows that all ports are closed. Everything is set up for the external IP address for his computer. My conclusion is that most likely something funky is happening with the college network. Are there any ways to get around this? Port forwarding is obviously not an option and he is only using the Windows firewall and I've allowed javaw and Minecraft_server.exe.

Code:

I believe Hamachi can sort you out. I'm not sure exactly how it works, but I know some people use it to get around school filters etc.

 

Depending on the university, they may allow your friend to host a server with the understanding that some ports will be blocked and that other web traffic take priority. Check out the school's IT department's website. You'll probably find something there. Alternatively, you can just rent a cheap server to save you the trouble.
