    Hello, we have configured the NAT rules in our firewall but when we use a port checker (https://portchecker.co/check) it shows that port 5090 is closed. We didn't change this port 5090 in 3CX so we expect 3CX to respond. But it isn't. Or is this a firewall problem?

    Hello @heusd045

    Does the 3CX firewall pass the check? Have you configured port 5090 for both TCP and UDP?

    Are all your services running? Have you tried connecting a 3CX client remotely using the tunnel? Does that work?

    I am going to contact the manufacturer of our firewall because everything in 3CX looks correct.

    Thank you
