This function can be "Enable" or "Disable".
When it is enabled, the "W-ICMP detecting" at the "Network Basic Setting" page
will not effect.
 Default Route: Select Galaxy router default routing, it is the main route.
There are three types of route can be selected: Radio, Ethernet and COM
(connecting with a dial-up modem). When Ethernet or COM is set as default,
the Radio will be the backup.
 Route Detecting: Detecting the destination host IP address, if there is no
response at the set time interval and times, the router will switch over to the
selected backup route.
 When the "Radio" is set to the default route and the backup routing
function is enabled, we recommend setting the operator's gateway as
the destination IP address for detecting.
 When the "Ethernet" or "COM" is set to the default route, we
recommend setting a reliable host in the Internet as the destination IP
address.
Attention: The destination host should work reliable. Otherwise, it will cause the
router switch over frequently.
 Backup route: There are two options.
 Gateway - When the "Enable Gateway" is enabled, the traffic will be
routed to this gateway via the Ethernet interface if the default route
failed. The gateway IP address is the network gateway IP address that
Galaxy router is connected.
 COM - When the "COM" port is enabled, the traffic will be routed to
Galaxy router COM port if the default route failed, and then the
connected modem will dial a number that specified at COM port setting.
