So you will need to talk to the administrators of this proxy (or the college's netwoork) and ask that they assign you an "outside of the college local-area-network" IP address (in other words, ask them to give you one of their wide-area network or WAN addresses) and forward requests for that particular IP address to your computer on port 80.
The reason you cannot do this without their cooperation has to do with the fact that LAN IP addresses are not routable outside the local subnet; There would be no way for someone outside your college's local network to connect to your server unless you have a WAN IP address, and that address is forwarded to your LAN IP addresses.
An alternative would be to sign up with a broadband internet service provider independent of the college. But you will need to find one that will give you a fixed (static) IP address, and that will allow you to run a server on their network; Many will not, due to network traffic engineering considerations.
