Hello.
I would like to change the port range of VRTSpbx / Symantec Private Branch Exchange service.
I found this article but it does not work for me.

How can i set a custom port range for pbx_exchange.exe?
kindly regards
Thorsten
You can try to limit port range for _all_ processes on OS level:

I tested it with a very few number of ports and it worked.
Thank you!
PBX uses port 1556 - this port is assigned by IANA so nobody else uses it.
I recommend you don't change the default port as you will have to change the port on all other Netbackup client and servers.
Please explain why you want to change the pbx port - has a oracle listener taken the port on a client ?
Best Regards

additional to port 1556 the service is using some random high ports
I don't want to change port 1556.
I want to restrict the upper port range.
See nbtstat -b:

I think what you are seeing is normal/expected
When making a network connection you have source and destination port. The destination port is what matters (e.g. port 80 www or 1556) - the source port or change of it is negotiated between the two hosts and can be any unassigned port - usually in the high range. Firewall are also aware of this - this is called stateful inspections.
Here is a example for browser connections made with SSL - port 443.
netstat -a -n | findstr 443
TCP x.x.x.x:50913 x.x.x.x:443 ESTABLISHED
TCP x.x.x.x:61069 x.x.x.x:443 ESTABLISHED
