we have problems with a VPN 3030 concentrator (Release 4.7.2G). we experienced two times that after a power outage the tunnels are not coming back. Reset on both sites of the tunnel doesn't help. The tunnel seems to come up, but there is no transmit acitivity. For another tunnel we cant see any activity by creating the tunnel, although by creating packets that should be forwarded through the tunnel.
When sending interesting trafic take a look at the real time log and see what is going on , ask the other side of tunnel if they see you hiting their end, this way you can at least see your logs and see if you are geting out.
the situation is strange. One tunnel is created but no traffic is trasmitted in the tunnel (statistic). The other tunnel is not created, with a sniffer we can see that the concentrator is answering the ping request with "not reachable". The log shows nothing for the second tunnel.
