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.

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? -- Dave Sherman Do not meddle in the affairs of dragons, MCSE, MCSA, CCNA for you are crunchy, and good with ketchup.
