The WAN2 link is defective

 

 

In the illustration above, the WAN2 link no longer functions The gateway RemoteTunWAN2 then appears as uncontactable and therefore unavailable. For the router ProductionRouter, both gateways RemoteTunWAN1 and RemoteTunWAN3 have been enabled and production traffic will then go through tunnels set up on the WAN1 and WAN3 links.
