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 W AN2, and when WAN1
restores, it will switch to WAN1 again.
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” or “SFP” for WAN1 (The main WAN).
WAN2:
Select“SFP” 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.
Note:
1)
The time set is for each probe cycle, but the decision to change to the backup port is determined by
Probe 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 in the screenshot, the connection probe will be carried out every 30 seconds, and 3
consecutive times of probe success is found, the router will determine failback to WAN1 (main WAN).
