Your university campus probably uses a system called network address translation (NAT) to connect your computer to the internet. That makes up an internal network IP for each computer on the campus, and directs any traffic from the wider internet through a single IP address. Once the traffic hits the internal university campus network the NAT system redirects it to the internal network IPs for each computer on the campus.

I have not yet found a way to sync an altcoin wallet through any network using NAT, but if there is a way I would love to hear about it.
