Winprint HylaFAX

I am not sure if this really is a question belonging here, but perhaps
someone has an idea how to solve this problem with Winprint. I haven't been
able to find any solution at the hylafax forums though 8(

I have the problem that I have to use an ssh tunnel connection to get to my
hylafax-server. As the data transmission port, once the control connection
is established, is randomly assigned, I can't create an ssh tunnel
(automagically).

The "regular" ports are tunnel'd (4557, 4559, 444), but the random ones
obviously not.

Is there a way to use some kind of sftp (coming with ssh) instead or any
other means of using the ssh "functions"?
