I don't think it is possible. I have used ssh tunnelling quite a bit,
and can see the following issues:

(1) There are a lot of ports that need forwarding
(2) Some ports would need forwarding in both directions
(3) An SSH tunnel requires that you connect to a port on the local
machine, whereas NetWorker connects to a remote machine. It might be
possible to do some sort of hack by messing with the hosts file, but
even if that was possible you would need to do this on both machines.

I wouldn't even want to attempt this. Perhaps you could rsync the data
if there is not too much needing backing up.
