I have a RV042G which I have configure failover from WAN1 to WAN2. When WAN1 disappears, internet access switches over to WAN2 as advertised. However, the VPN tunnel does not. The tunnel is configured for WAN1 with Keep Alive, Dead Peer Detection and Tunnel Backup with the remote backup address the same as IP address, the local interface set to WAN2 and the VPN Tunnel Backup Idle Time set to 30 seconds. I have several more of these to configure, so your assistance is appreciated. Thank you.
