Unsupported 3CX Firewall on windows server 2019 -

[howar]

Dear,
Greeting

I have a problem with 3CX installed on windows server 2019.
all ports are blocked even after making port forward to 3CX and DMZ from the router.
on windows server firewall allowed all ports.
https://www.3cx.com/docs/ports/ mentioned inbound and outbound f


the gateway is registered successfully with 3CX through 5060 but the 3CXblocked it 10.10.10.202:5060


As you see the gateway attached is registered with 3CX

Please advice
