IPSEC Site-to-Site as Backup to Wireless Link(
-
I have a wireless link between two sites where Site A has an interface that is bridged to Site B.
Site A Site B
(WAN - x.x.x.x) (WAN - x.x.x.x)
(WAN2 - 10.0.0.30/24) ((())) (LAN - 10.0.0.1/24)
(LAN - 192.168.10.0/24)Everything is working fine but I want to create an IPSEC site to site as a backup link incase the wireless link goes down. The problem occurs when I set up the IPSEC phase 2 with remote network of 10.0.0.0/24. I can't set the IPSEC as a gateway or policy routing. How do I get it so i can get a transparent backup link when wireless goes down?

Also, I am hooking up to a Edge router on the other side. It seems that edgeOS supports VTI (Virtual Tunnel Interface) for IPSEC. When will pFsense support "routed IPSEC"? If it is routed, I believe we can treat links as gateways and do load balance and failover correct?
