input. The maximum acceptable groups is two IP groups.
Enable Line-Dropped
Scheduling
：
The WAN disconnection schedule will be activated by checking this
option. In some areas, there is a time limitation for WAN connection
service. For example: the optical fiber service will be disconnected from
0:00 am to 6:00 am. Although there is a standby system in the device, at
the moment of WAN disconnection, all the external connections that go
through this WAN will be disconnected too. Only after the disconnected
lines are reconnected can they go through the standby system to
connect with the Internet. Therefore, to avoid a huge number of
disconnection, users can activate this function to arrange new
connections to be made through another WAN to the Internet. In this
way, the effect of any disconnection can be minimized.
Line-Dropped Period
：
Input the time rule for disconnection of this WAN service.
Line-Dropped Scheduling
：
Input how long the WAN service may be disconnected before the newly
added connections should go through another WAN to connect with the
Internet.
Backup Interface
：
Select another WAN port as link backup when port binding is configured.
Users should select the port that employs the same ISP.
After the changes are completed, click
“Apply”
to save the configuration, or click
“Cancel"
to leave
without making any changes.
Static IP
If an ISP issues a static IP (such as one IP or eight IP addresses, etc.), please select this connection
mode and follow the steps below to input the IP numbers issued by an ISP into the relevant boxes.
