Billion M500 - Dual WAN; General Setting

Dual WAN
Dual WAN is specially designed to offer users failover/fallback.
Auto failover/failback is to ensure an always-on internet connection. Users can set a WAN1 (main
WAN) and WAN 2 (backup WAN), and when WAN1 fails, it will switch to WAN2, and when WAN1
restores, it will switch to WAN1 again.
General Setting
Select "Failover & Failback" or "Failover & Proirity" to enable the failover/failback feature to keep WAN
always on or "Load Balance" to maximize WAN band width.
