What a port scan would find really depends on how your university's
network is setup. Is a web proxy in use, as opposed to a web cache
or nothing at all? Is your host on public address space, or are you
on private address space with another device on the network handling
network/port translation? Is there a firewall in place at the
school's handoff to the ISP?
You need to find out the answers to some of these questions. One
thing you can try to lead you in the right direction, go to a website
that identifies your IP address, like http://www.ipchicken.com/. Is
that IP your IP address? If it is, then you have a direct connection
to the internet. A firewall at the handoff may still be blocking
certain ports, however, so a port scan would be hitting the firewall
on those ports. If the IP address you get back from ipchicken is not
the address configured on your machine, then it is probably that of a
proxy or translation device.
