Backup WAN Connnection - NETGEAR 4G LTE Modem

[SecurityPlus]

Has anyone used a Netgear 4G LTE Modem (LB2120) as a backup WAN connection on a FortiGate. The primary WAN 1 connection will be a fiber connection. Would like a fail-over WAN 2 connection using SD-WAN in the event the fiber connection fails. Are there other alternatives to this that should instead be considered?

As long as it's connected over ethernet, the brand/internet media type shouldn't be a matter. It could be in router mode to have another subnet between the modem/router and your FGT or in bridge mode that the modem provides just media conversion. Either way it's just another internet connection.

We think that we need to set this up as a redundant internet basic failover instead of using SD-WAN. https://cookbook.fortinet...net-basic-failover-56/ SD-WAN looks as though it was consuming some bandwidth on the cellular modem even though the primary fiber connection had not failed. The cellular does not have a static address. The Netgear modem offers a bridge mode or a router mode. Which mode should be used? From the perspective of the failover / failback it seems that the Netgear needs to do routing so that we can run it using a consistent gateway address of 192.168.5.1.
