Hi,
We are having a new phone system which is 3CX. I have been asked to open some ports.I am not sure how to do that.
There is a manual from the 3CX vendor but it is for 80C.

To verify:
config system session-helper
show full
Verify that SIP, RAS and H323 are 13, 3 and 2 as mentioned below. If so, proceed as follows:

Hi Tazio,
Thank you for the query!
As per the topology I understand in your scenario firewall will be acting as a NAT device for your H323 traffic. In this case, you want to know how to create a NAT rule to route your traffic received on public IP to your internal server with private IP.
