    I can't register an x-lite phone from outside.
    From inside the firewall check fails with the following errors:

    1 9000 Error (4) Global address (returned by STUN) is not accessible from outside. This issue can be generated only if a STUN server is defined for checking. addrFromSTUN =

    2 9000 Error (6) Different NAT translation for different requests (to STUN and to Firewall Checker Agent). This situation can occur if there is something wrong with NAT translation or a symmetric NAT is used. addrFromAgent =
    addrFromSTUN =

    3 9000 Warning (8) Local port is not blocked from outside. STUN server has returned global port different from the local one, but the local port is also accessible from outside.
    4 9000 Warning (10) Port number has been changed during NAT translation. externalAddress =

    My firewall reports that all is well:
    <84> Dec 9 15:36:32 FIREWALL rule (1 of 3) : Protocol: UDP Src ip: Src port: 4200 Dst ip: Dst port: 9000 Chain: forward_host_service Rule Id: 46 Action: accept

    <84> Dec 9 15:37:15 FIREWALL rule (1 of 1) : Protocol: UDP Src ip: Src port: 2281 Dst ip: Dst port: 5060 Chain: forward_host_service Rule Id: 45 Action: accept

    -> the first entry is the firewall check;
    -> the second entry is my x-lite phone connecting to the 3cx server

    The x-lite phone seems to be registered on the server, but the extension is unaware (408 error).

    What is going wrong with the STUN-test on the server?
