We have Expressway E dual NIC deployment and i have question regarding the ports H323. On the firewall port 1720 TCP already open but still it showing closed on the TAC CSA SRV and port test.
On the Expressway E H323 protocol configuration, why the LAN 2 (outside int.) IP and ports are not showing while for SIP is showing??? Is this normal? We are thinking port 1720 is not activated on LAN 2 of Expressway-E tha'ts why port 1720 is not reachable from internet.
Do you have the appropriate DNS SRV records required for H.323?
Port 1720 should be showing as open on the CSA under normal circumstances, so no this is not normal.
Have you checked the event logs on Expressway C and E for anything untoward?
What version of Expressway are you running? Have you consulted the IP Port Usage document for your version of Expressway? As an example, here is the 12.5 version:
I have the same status too. Having done a bit of digging, I expect this is normal behaviour.
Did you notice this thread at all? Looks like it's a similar query to yours:
