ABOUT THE INTERNET CONNECTION
2-9
The WAN Failover function automatically switches the default gateway port to maintain Internet connectivity.
If a connectivity failure occurs on the [WAN1] port (the main port), the WAN Failover function automatically routes
all traffic through the [WAN2] (the backup port) port.
