IPSEC Tunnel trouble between two VRW200

    Hi,

    First...a note of disappointment: Linksys tech support seems to say: "You have selected a product that is not supported via Linksys Chat." I am not sure why...is it not supported model any more?

    Anyway...the real problem I have is:

    I got 2 sites. Both use a VRW200 router with Firmware Version: 1.0.39 .
    The routers do their job nice on LAN and WAN and WLAN.

    I need to connect the 2 sites via VPN IPSEC tunnel to ensure resources can be shared...imagine as a mini branch office and a Small main office.

    QuickVPN works nice for both, that is how I can manage both routers from home, but we need more, a tunnel between the 2 networks.

    I set up the tunnel on both ends using exact same settings, except, the branch accepts connections from ANY and main office calls branch by FDQN using dyndns.

    In VPN summary of the Branch, the status is ANY, in the office it is T (Try to connect to Remote Peer.)
    The connection seems to be up for a while...not short, but less than a day even with this T status, but it never becomes C and it disconnects eventually.

    Pasting here details of VPN tunnel from main office (altered the IP adresses a little bit but consequently):

    Please anyone can help me to get a C into connection status?
    Thanks,
    Dezso

    The WRV200 has an issue with incorrect tunnel status reporting, when the other end is on DDNS. In such a case it always says T, when it schould say C.
