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?
 
The 3CX firewall passes the check and port 5090 is configered both for 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
 
That sounds good. Please let us know if you need further assistance or when you have a solution to your issue.
