you can use the ALLOW_NON_RESERVED_PORTS option to use ports 1025 to 5000.

Subject: [Veritas-bu] Still Another Question on Firewalls, Ports and
Security


I think I'm pretty clear now on which ports have to be accommodated within
the firewall to allow NetBackup connections but there is still one question
floating around out there that begs answering ...

"Is there a way to limit which ports NetBackup will use (something less than
the complete 512 to 1024 range) thereby insuring that a minimum number of
ports will have to be defined to the firewall software?"

My security guys are having a baby buffalo at the notion of allowing
NetBackup to have 512 ports available for use. I personally don't know if
that number is good or not nor if it represents a real security concern.
They are more interested in a total number of available ports being 25 - 50.
And oh by the way, they want to choose the range as well (ie; 1000 - 1024).

Any information would be greatly appreciated. I suspect that if the answer
is "You can't do it that way" They'll set me up with the 512 - 1024 range.
But hey ... I gotta at least say I asked.

Regards,

Dennis
