    I'm trying to to get my Firewall Test to pass, mostly just because it annoys me that it's failing. I have a Static 1:1 NAT configured for my 3CX server, and firewall rules permitting the traffic. Inbound SIP works without issues. However I keep failing the "Full Cone Test". I have a Juniper SRX firewall securing the network.

    What exactly is the "Full Cone" test and why would it still be failing with a 1:1 static NAT?

    Hi Robert,

    Can you confirm what ports are not passing the test?

    Regards,

    All of the ports are failing. 5060, 5090, and the 9000-9255. I'm not seeing denies in my traffic logs.
