If you're behind NAT or a non-stateful firewall, you typically need to
use PASV. If the server is behind NAT or a non-stateful firewall, you
should not use PASV. If you're both behind NAT or non-stateful
firewalls, you might not be able to use FTP at all (for non-encrypted
FTP, a NAT helper on the firewall can re-write traffic to make active
mode work).
Since you're able to reach the server from off-site, the problem is
probably the firewall used by the clients on campus. If you don't run
that, you should mention the issue to the people who do (MIS?).
