I am trying to set up my Sonicwall TZ-210 as follows:
- Two WAN interfaces (different ISPs), set up in failover mode.
- Two LAN interfaces with different subnets
- Each LAN subnet will have a preferred outbound WAN interface, but would failover when necessary.
In this way, each ISP is being used for a separate subnet of my network, but both subnets could failover to the other ISP if their primary went down.
I know how to do 1 and 2, but I don't know how to do 3. I could set up a route for each subnet to go through a specific interface, but what would happen in the event of a failover? Would it automatically update those routes?
Thanks!
