Opening Port

I am running SuSE 10.2. I do not run the firewall since I have a HW
router and most ports are shut down. I am trying to connect to a
service on the box on port 3200 from within a private network, but it
is failing. Using
nmap, it tells me that only the following ports are open.

I suspect that since 3200 is closed, it is the reason for the
failure. How do I open it? Maybe I am misinterpreting it. Does the
listing below mean only these ports are available, or they're they
only ones that are currently active.

I was under the impression that unless you had a firewall running, all
the ports were open. Thanks for any help.
