    Default iPSec Tunnel - Suddenly Stops Working

    Hi - I have been using a number of IPSEC VPN tunnels for a number of months - all of a sudden some (not) all of the tunnels have been dropped and will not connect.

    I am using Draytek Vigor 2830 - to create a LAN to LAN Tunnel back to Untangle.

    Link below is an extract from the Tunnel Log - has anyone any idea what might be up?
    A previous working Tunnel was - this will no longer connect.

    Any help greatly appreciated

    If I'm reading this correctly, it seems the Untangle is unable to reach which I imagine is your remote site.

    Hi - thanks fro your reply.

    I can ping from Untangle and the firewall is disabled on the Draytek, so I can't understand the error.
