Overlapping subnet on WAN 2

Firewalla gold: I have a verizon mifi hotspot that I need to failover to when the primary WAN is down.

Primary WAN is AT&T.

Wireless is Verizon -> to be used as failover.

I'm getting this message.

The subnets of ISP 1 (192.168.1.205/24, Wireless (192.168.1.6/24) overlapped. Please check settings and resolve the conflict.

Can someone provide a solution to this? Thanks in advance!

You can't have two WAN on the same sub-network. What you need to do is change one of the WAN links to say 192.168.2.x/24.

Chang the WAN side IP addresses, you will need to do it either your ISP1 or Wireless modem/router. (it is not a firewalla thing)

That was the issue. Changing the WAN IP on the mifi device resolved the issue. Failover works awesome now! Thanks you!
