in comp.security.firewalls i read:

no, and it's not even possible the way that sshd's are currently written,
e.g., port 22 can't be tunneled because the other end-point already has it
open. (your end might too.)

it's time for you to move beyond ssh, to a vpn. perhaps ipsec is available
for both ends. since you are posting to a firewall group i'll assume that
you have such a thing (at both ends?), and say that the documentation for
it/them is the right place to start.

>>From what I've read, UDP cannot normally be tunnelled through SSH, though?

it could, but nobody has written any code to handle it, except for x11.
the trickiest part is that since the ssh tunnel is, in effect, a nat you
will probably also need code to handle upper level protocol messages which
have lower level protocol data embedded.

that's because that's not what ssh was designed to handle.
