[p4] client on secured network

[Samuel M T Ehrlichman]

Hello all.  I am a graduate student who has been using the 2-user  version
of Perforce to manage files between my home and office
computers.  I run p4d on a small Linux box in my home.  Everything has 
worked swimmingly up until last month, when the administrators for the 
network at our department got paranoid and decided to block most traffic 
to and from the network.  Currently, email, http, and ssh work, but not 
much else does (e.g., no ftp, no ping or tracert, etc.).  Needless to 
say, p4 does not work anymore either.

Does any of you p4 experts know a way I can continue to use p4 from the 
office under the circumstances?  Can I get the client to use http 
tunneling or something like that?  (The documentation regarding ssh 
tunneling seems to focus on the situation where the *server* is on a 
secure network, which is not the issue here.)

If I need to ask the administrators to make changes, what would be the 
likely minimal change that would get things to work?

Thanks so much.
