Hello,
I am configuring my router and I want to setup the scenario as following:
LAN1 = 192.168.1.0/24 - eth5
LAN2 = 192.168.2.0/24 - eth5
WAN1 = 10.0.0.1 - eth1
WAN2 = 10.0.1.1 - eth2
I need to route my traffic from LAN1 to WAN1 only using policy based routing and LAN2 traffic over WAN2 only. But in case any of the links go down the traffic should be routed to the backup WAN i.e. if WAN1 goes down then LAN1 traffic should be diverted to WAN2. Also when the link comes up it should be diverted back to WAN1 only.
Any suggestions or help will be highly appreciated.
