NBU 6.5.5 Port requirements

[Dan_Giberson]

We are moving our Master and our Media servers behind firewalls away from most of our clients.Currently we are running NBU 6.5.5 with client versions ranging across the board. I just want to make sure my firewall rules are set up properly. I have looked at the Port Usage document from Symantec, and as far as I can tell I need the following ports:
13724
13783
1556
2821
4032

I'm not sure about the last two...let me know if there are any others that I am missing.

As well, since our master and media servers are separated by datacenters, what ports are needed for them to talk to one another:
13724
1556

any others?

thanks.

13783 is for vopie (legacy security - veritas one-time password in everything) - do you have it configured? I honestly do not know anyone still using it...

2821 and 4032 are for Authentication and Authorization. You will know if you have it configured.

Under normal circumstances you only need 13724 and 1556 (bi-directional).

Up to NBU 7, server-client comms only use13724 and Media Manager comms use 1556, but it seems Symantec is moving towards 1556 for everything. See this discussion:

https://www-secure.symantec.com/connect/forums/701-clients-making-calls-1556-pbx

So, best to start making provision for 1556 for server-client comms as well.

Thanks guys.

On a related note...We ran a vulnerability scan on our Master and Media servers and noticed that port 4673/TCP keeps popping up during backups...any ideas?

In August, 2005, IANA officially registered port 4673 (TCP and UDP) for "CXWS Operations", meaning it's the standard port used by the CXWS binary streaming protocol.  http://www.piazzafamily.org/jeffpiazza/work/cxws.html
