So I am hoping for some general guidence. I have set up 2 RV110w firewall/vpn/routers at remote locations and an ipsec tunnel between them. Once the tunnel gets established everything works fine until it has been idle for some arbitrary amount of time. (Maybe a half hour or less.) at which point we lose server access and can no longer ping across the tunnel. To fix this I have had to dissconnect and reopen the tunnel again, I even went so far as to install an autopinger on the remote end to keep traffic on the tunnel which seems to help but is not going to be a viable long term solution. I expect that I am doing everything wrong entirely but any sort of guidance would be much appreciated. Called cisco support and the gentleman I talked to was both very nice and very unhelpful, he seemed to be unsure of what any of the various settings really did and sounded like he was guessing.
