Solved firewall test SIP ALG problem

[next2]

Hi,
This is a new install. All necessary ports have been forwarded to the ipbx.
There is one error while running the firewall test :

detecting SIP ALG... detected (sent fd4af46e ≠ 98a4010a, received 58d6f8a2 ≠ fc3a540d)

What does it mean exactly ?
Thank you !

Hi @next2 ,

SIP ALG is a feature on gateways that modifies the packets, for 3CX to work correctly this has to be disabled.
You can find more info about it here: https://www.3cx.com/docs/firewall-checker/#h.ikh44hto4r56

Hope this helps!
