Argue with the administrators and tell them why you need these ports open
and why it doesn't represent a threat to them to have them open. You
can also ask them to open them on a case-by-case basis, let's say just
to your computer or server. They cannot interfere with the mission of
the school, which is what they are doing if they restrict your ability
to do research. That would be my line of argument.
