We have two RVS4000 routers set up with a site to site VPN. If there is an interuption in the ADSL line, the RVS4000 VPN drops and does not start up when the ADSL line is reconnected. The VPN can be started manually. Is there a way to have the VPN re-established automatically?
It doesn't seem to. Previously we had two Linksys RVO42 routers and they re-connected without any problems. One of the RVO42s failed and both were replaced by the RVS4000s then we started having problems. I will do some more testing tomorrow and get back to you.
RV042 supports Dead Peer Detection to keep the tunnel alive, but RVS4000 not. When a tunnel disconnects, RVS4000 will re-connect the tunnel only when there is VPN traffic that tries to go on the tunnel.
