When Fail:
(1) Generate the Error Condition in the System Log: If an ISP
connection failure is detected, an error message will be recorded in
the System Log. This line will not be removed; therefore, the some of
the users on this line will not have normal connections.
This option is suitable under the condition that one of the WAN
connections has failed; the traffic going through this WAN to the
destination IP cannot shift to another WAN to reach the destination.
For example, if users want the traffic to 10.0.0.1 ~ 10.254.254.254 to
go only through WAN1, while WAN2 is not to support these
destinations, users should select this option. When the WAN1
connection is disconnected, packets for 10.0.0.1~10.254.254.254
cannot be transmitted through WAN 2, and there is no need to remove
the connection when WAN 1 is disconnected.
(2) Keep System Log and Remove the Connection: If an ISP
connection failure is detected, no error message will be recorded in
the System Log. The packet transmitted through this WAN will be
shifted to the other WAN automatically, and be shifted back again
when the connection for the original WAN is repaired and
reconnected.
This option is suitable when one of the WAN connections fails and the
traffic going through this WAN to the destination IP should go through
the other WAN to reach the destination. In this way, when any of the
WAN connections is broken, other WANs can serve as a backup;
traffic can be shifted to a WAN that is still connected.
Detecting Feedback Servers:
Default Gateway:
The local default communication gateway location, such as the IP
address of an ADSL router, will be input automatically by the device.
Therefore, users just need to check the option if this function is needed.
Attention! Some gateways of an ADSL network will not affect packet
detection. If users have an optical fiber box, or the IP issued by ISP is a
public IP and the gateway is located at the port of the net café rather
than at the IP provider’s port, do not activate this option.
ISP Host:
This is the detected location for the ISP port, such as the DNS IP
address of ISP. When configuring an IP address for this function, make
sure this IP is capable of receiving feedback stably and speedily. (Please
