IPsec VPN Connection With Dual WAN Link Backup Using TL-R600VPN?
When setting up an IPsec Lan-To-Lan VPN policy, I see that I need to specify a WAN port. Is there a way to setup the TL-R600VPN so the VPN connection is reestablished on the backup WAN when the primary WAN is down?
If it matters, site A has two ISPs and can be setup to be the Initiator of the tunnel and site B has one ISP (at the moment) and maybe have its VPN policy configured with 0.0.0.0 as the remote host. Both sites would have Dead Peer Detection setup and I assume Site B would detect the connection as down and delete the IPsec SA while site A would reestablish the tunnel under the backup WAN / IP address.
