I have a TL-R600VPN with site-to-site IPSEC vpn established. I need to setup a failover WAN (working), but I need the VPN tunnel to also switch over to the failover WAN when the primary WAN goes down (not working).
The IPSEC tunnel is set to authenticate locally with Name, not IP--so it would work fine for purposes of the tunnel. I just can't get it to switch to the backup WAN link when the primary goes down.
I also tried creating a second tunnel bound to the secondary WAN, but cannot do that either due to overlapping local and remote subnets.
Any assistance would be much appreciated!
