Hello, I am not able connect to the 3CX server through the Internet. Only through the local network. I have done the tests with two open networks, with the firewall off. I get the public IP of the 3CX server connection and try to use the tunnel to make the connection, but he can not. If I try to use the tunnel on the internal network, it works normally, but never succeeded in the external network connection. Recalling that there is no firewall enabled, and the two networks are open to the test. Should not connect?
