SSH works through my 678 just fine. My nat entry is exactly the same,
except for my IP addresses of course :-). My server is running RedHat
7.2, recently upgraded from RH 6.2. Very smooth upgrade, by the way.

The symptom makes it sound like your tcp packets are either (1) not
reaching the server, or (2) reaching the server, but the server is
unable to respond back to your client. Do you have any other ports being
forwarded by your 678? Web or mail, perhaps, that you could test? Have
you verified that your server is able to reach the 'Net? If not, do you
have the correct default gateway setup?
