4.4.2 Dual WAN
Dual WAN is specially designed to offer users Failover/Fallback or Load Balance feature.
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.
WAN 2 (backup WAN), and when WAN1 fails, it will switch to WAN2, and when WAN1 restores, it will switch to
WAN1 again.
4.4.2.1 General Setting
Select Failover to enable the failover/failback feature or Load Balance to make the router work in load balance
mode.
Failover
WAN Port Service Detection Policy
WAN1:
Select “EWAN”, “SFP” or “3G/4G-LTE USB” for WAN1 (The main WAN).
WAN2:
Select the “SFP” or “3G/4G-LTE USB” for WAN2 as backup port if you select “EWAN” as WAN1.
Connectivity Decision:
Set how many times of probing failure to switch to backup port.
Probe Cycle:
Set the time duration for the Probe Cycle to determine when the router will switch to the backup
connection (backup port) once the main connection (main port) fails. For example, when set to 30 seconds, the
probe will be conducted every 30 seconds.
probe will be conducted every 30 seconds.
Note:
1) The time set is for each probe cycle, but the decision to change to the backup port is determined by Probe
Cycle
Cycle
multiplied by connection Decision amount (e.g. From the image above it will be 30 seconds multiplied
by 3 consecutive fails, the router will determine failover to WAN2 (backup port)).
2).The failback setting follow the same decision policy as the failover. For example, according to settings above
