Failover WAN

[Peter847]

Not sure I'm posting in the right place . . .

I have two WAN interfaces, WAN0 is a regular cable modem and WAN1 is a 4G modem.  I setup a failover group to use WAN0 if it was available and fail over to WAN1 if it wasn't.  This worked but if WAN0 failed my LAN used so much data on WAN1 that I exceeded my data limit.

To limit the data I only want critical devices to failover to WAN1, the rest can wait until WAN0 comes back on line.  I intend to make the following changes to the default Failover setup in the OPNsense documentation.

• Do not create the firewall rule to direct all the LAN traffic to the Failover Gateway Group.
• Instead create a firewall rule that only directs LAN traffic from the critical devices.

Will this work?

Yes!
