Netgear LB2120-100EUS Automatic Failover in Bridge Mode possible?

Hello,

I want to use the Netgear LB2120-100EUS as an automatic failover device that is switching from DSL to LTE when

the cable broadband connection fails. The Netgear LB2120-100EUS should be connected to a firewall / router (via LAN cable).

Out of this reason the Netgear LB2120-100EUS has to be set into Bridge Mode.

Is the automatic failover feature in Bridge Mode available?
