Hi Mates,


I have a lot of issue with a complex architecture composed by a couple of gateways CP3200 (in a clusterXL configuration) connected via VPN  to many CP1430 (#40) remote gateway CP1430. Other notes: the remote gateway are behind layer-3 NAT device. the provider router NAT all necessary ports to the gateway external IP. In addition the remote gateways have two ISP connection.


The remote gateway are defined into the management as external managed gateway (they are managed from the Local WebUI)


The VPNs are fine and we can establish correctly the tunnels but we face with randomically tunnel dustruption and not always the tunnels comes up automatically in short time...


How can we debug this random disruption?
We already configure the permanent tunnels and tunnel test
what parameter/variable can cause the service disruption?
