Hi, Is there anybody there in the list that has experience setting up VPN connection using 2621 routers -12.0.7(T) ? The connection stays up as long as it used, when it's idle for an hour or so it drops. The only solution is to clear the tunnel with clear crypto isakmp clear crypto sa and then I have the tunnel up and running. I have tried crypto keepalive command but does not work ( i.e. crypto isakmp keepalive 300) Any idea ?
