Good Day,
Anyone had luck configuring a 3CX telephone server to go through a RT-AC88U (or equivalent) firewall? I've assigned the port forwards in accordance with the 3CX manual, but remote phones cannot connect. Everything works internally, but phones from the outside world cannot connect.
If you could share your settings for such a set-up, it would be very helpful.
Cheers.
