    Hello all.
    I have some issues regarding 3CX Phone System and client. I will try to be clear, and expose these issues, one by one. I hope someone can help me around.

    I am running 3CX Server (3CX Phone System v6.0.570.0 FREE VERSION) on Win2000 Server. No Firewall here. LAN address 192.168.3.250
    I use a home internet connection (ADSL with 2MB Download & 256KB Upload).
    I am using DYNDNS to resolve mi connection IP Address. I have configured that name example.dyndns.org in my 3CX Server ==> Allow calls to external SIP URIs is checked; and the local SIP domain is my DYNDNS name.
    My LAN is 192.168.3.X
    Between the ADSL and my LAN I have a Linksys WRV200 Router. I have set up PORT FORWARDING as follows:
    PORT-------TCP---UDP---DESTINATION
    5060---------X------X-----192.168.3.250
    5090---------X-------------192.168.3.250
    9000~9020--X------X-----192.168.3.250

    I have 3 PCs, one notebook and 1 IP telephone on my LAN. All of them connect register as extensions with no problems.
    The problem is when I try to register remotely, from WAN. I have tried using DYNDNS name and IP Address at the 3CX Client. After that I have configured the TUNNEL tab, and selected to use this option. The configuration is as follows:
    IP or FQDN: 192.168.3.250
    Extension: 13
    Pin: 13 (its correct)
    In the TUNNEL tab:
    "Use TUNNEL to connect..." is checked
    Use tunnel of host: example.dyndns.org (tried the IP address too) ==> port 5080
    Remote end of tunnel: example.dyndns.org (tried the IP address too) ==> port 5090
    Tunnel password: *** (its the same one set at the 3CX server)

    As I cannot register extensions from WAN, I did the FIREWALL TEST from the "General Settings" and got these results:
    Only two errors:
    6 9005 Error (4) The STUN server returned an ip which is not accessible from outside. addrFromSTUN = 222.222.222.222:9005 (where 222.222.222.222 is my WAN IP)
    13 9011 Error (4) The STUN server returned an ip which is not accessible from outside. addrFromSTUN = 222.222.222.222:9011 (where 222.222.222.222 is my WAN IP)



    What am I doing wrong? Or what am I not doing?
    Thank you very much in advance!

    Hi Matt, thanks for your answer.
    Should I think about getting to my server via VPN from WAN?
    WRV200 supports VPN connections, but I have really never could get through with that.
    In the other hand, VPN traffic is encrypted and de-encrypted on both ends. This should impact performance, or not?

    What I really have seen is that WRV200 should work perfect with 3CX ==> http://www.3cx.com/forums/linksys-wrv200-router-has-lost-connection-and-dhcp-issues-5112.html

    Any other idea?

    I understand Matt. But this solution would take me to buy another wrv200?
    During my testing yesterady I found out something strange.
    I have installed XLite and I can register remotely on my 3CX now. But I cannot do it using 3CX client. Strange, isn´t it?
