    Dear Friends,

    I need your kind help for publishing 3CX Server behind of my router, here is my scenario:

    I have a CISCO 1841 Router,
    Installed 3CX Server on Windows Server 2003, which is a member of my internal domain controller,

    I configured my router with these following static nat statements:
    ip nat inside source static tcp 4300 interface FastEthernet0/1 4300
    ip nat inside source static tcp 42019 interface FastEthernet0/1 42019
    ip nat inside source static tcp 42000 interface FastEthernet0/1 42000
    ip nat inside source static tcp 5070 interface FastEthernet0/1 5070

    But problem is that when I try to telnet any of the above port from the out side of my network using any other gateway or trying to connect from the 3CX server it self, so none of any port is responding.

    I checked the server status from the 3CX web console and it is looking that it is genrating the randum ports for SIP connection / STUN.

    With I am trying to connect with my 3CX Server from the other gateways like with putting this below connection details:
    3CX System / SIP Server : (my external IP)
    with my exten: 100
    PIN : 100

    So it is trying to discover network but after some while it gives the "STUN Server Error".

    Kindly try to help me out for this issue.
