Hello and thanks for you answer.

I have checked the HLADDRESS and LLADDRESS values and they are correct. I don't 
know if something is buggy, but when starting dsmcad it won't bind to port 1501 
even if I use TCPCLIENTPORT or not. The lsof command shows this:

dsmcad     3095    root    4u  IPv4     500722                TCP *:41363 
(LISTEN)

If it might be of some help, this a RedHat Linux 9 server.

Dan

1501 is the default, anyway.  (You can verify what the client is listening
on via the 'lsof' command or equivalent.)

Note that you are using SESSIONINITiation SERVEROnly, which says that the
server will initiate the session according to the node definition
HLADDRESS and LLADDRESS values.  Check those, and inspect the server
Activity Log for anomalies in attempting sessions with that client.
Use DEFine CLIENTAction to experiment and prove session capability
through the firewall.
