Gigabit SSL VPN Security Router User’s Manual
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.
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 This is the detect location for DNS. (Only a web address such as
Host
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.
