How to assign a DB2-Instance to a unique IP-Address (and Port - of course)

I was told, this is not possible, but other products like Oracle or
MQSeries do support this! What is true, what are the reasons?
Is there a security risk, because the DB2-Instance provides service
to any IP-Endpoint of a machine, just because of the addressed port?
Thanks a lot! Wolfgang, Munich

Please define what you mean by "assign". When you catalog a remote TCP/IP
node, you must specify a host-name or IP address.

That's when you have two network cards in your DB2 server system and
you want DB2 to accept client connections thru only one of them.

I couldn't find anything in the DB2 manuals but using a software
firewall might be an option.

Indeed, I guess you'd set your firewall rules to only open the DB2 port
(e.g. 50000) on a specific IP address.
