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
input the DNS IP of the ISP port)
Remote Host:
This is the detected location for the remote Network Segment. This
Remote Host IP should better be capable of receiving feedback stably
and speedily. (Please input the DNS IP of the ISP port).
DNS Lookup Host: This is the detect location for DNS. (Only a web address such as
www.hinet.net is acceptable here. Do not input an IP address.) In
addition, do not input the same web address in this box for two different
WANs.
Note
！
In the load balance mode for Assigned Routing, the first WAN port (WAN1) will be saved for the
traffic of the IP addresses or the application service ports that are not assigned to other WANs (WAN2).
Therefore, in this mode, we recommend assigning one of the connections to the first WAN. When other
