DNS Server Input the DNS IP address set by ISP. At least one IP group should be
input. The maximum acceptable is two IP groups.

LAN IP Range 1 and Internal LAN IP Range 2 respectively.
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.
Router Plus NAT Mode
：
When you apply a public IP address as your default gateway, you can setup this public IP address into a
LAN PC, and this PC can use this public IP address to reach the Internet. Others PCs can use NAT mode to
reach the Internet.
If this WAN network is enabled the Router plus NAT mode, you can still use load balancing function in this
WAN network.
