Certainly a possibility.  We don't have enough information to say for sure.

TCP.

That's not the default port.  But if that's the one the server's listening
on, that's the only one you need.  

If you have FreeTDS 0.60 or later, try tsql from your development machine
(see "man tsql").  You can use tcpdump to see if you're getting a reponse
from the server.  

HTH.
