Netbackup uses the 4-5 dedicated 137.. ports.

In addition, it uses 512 to 1024 for port allocation and window
accessibility.

In addition, it uses 1025 to 5000 either dynamically or incrementally, based
on a setting in your master servers bp.conf  or lack thereof.  These ports
are for the communication interchange.

There is a "beta" doc on the port usage available from your rep at Veritas.

We also have firewall, and the backups stopeed working when the firewall
team blocked the 'ping' ability between the machines.

Apparently NBU doesn't only check 13782 but first tries ping in both
directions, which we didn't find documented. When ping was allowed - the
backups worked again.

Our firewall person said that low ports like 1014 etc are opened
dynamically by the clients, are accepted as such by the firewall, and
do not need to be configured.
