ssh out with -R mapped to the local 22 and the
other end at some non-reserved port (e.g., 65432).

On the other hand, you are bypassing the
site security rules by doing this. Someone
considers blocking inbound ssh access reasonable
and may be unhappy about you installing a back
door on them.

If this has anything to do with your work
computer I'd suggest getting some written
(e.g., printed email or longhand) confirmation
from the firewall's manager (or your boss) that
bypassing the firewall rules is OK or you can
get heavily slapped (see "Just Another Convicted
Perl Hacker" for a good description).
