RV-042 IPSec problems

    First time post so apologies in advance if I'm being thick! I have the following scenario:

    Head office using: internet->Netgear DG834 ( to provide DSL)->RV-042 ( for VPN)

    connecting to 16 remote sites just using Netgear DG834s for VPN as well as DSL (192.168.x.1).

    N.B. The head office is using dyndns, the remote sites are static ip.

    Problems as follows:
    1. If I reboot the remote device and then establish the tunnel everything works fine at first (can access remote subnet). However, with keep-alive enabled the tunnel appears to re-establish okay (after 3600 sec) but I can then only ping the remote router and not the lan behind it.
    E.G. ping to works but does not.

    If I manually take the tunnel down and back up I can then ping okay again?

    2. Thought I'd try without keep-alive but the tunnels don't re-establish at all then from the RV-042 although bizarely they do connect if I remote admin the 834 and connect from that side.

    It would be easy to blame the 834's for the problem but it used to work rock solid just using the 834 at head office for ipsec but unfortunately this only supports 5 tunnels.

    Any help appreciated!
