XG Failover rules

I have setup: Port2 WAN Static, set Active in my failover rule in Link Manager.

Port8 WAN Failover DHCP (its a 4G cradlepoint) set as Backup in Link Manager.

I set the backup to activate on Any gateway fails.

Test worked perfect right on time (30sec)

Do I need worry about adding any Failover Rules ?
