Route:
Detect connection with route method, when choose this method, users
should also configure "Detection Interval", "Primary Detection Server IP"
and "Backup Detection Server IP" items.
PPP:
Detect connection with PPP method, when choose this method, users
should also configure "Detection Interval" item.
Detection Interval:
time (in seconds) to wait between detection attempts.
Primary Detection Server IP:
the primary (first) server that should be reachable and
respond to the configured detection method
Backup Detection Server IP:
the backup (second) server that should be reachable
via the WAN interface and respond to the configured detection method
Note:
Both the primary and backup detection servers should be stable and
reliable
–
if these servers fail to respond correctly in a timely manner, the modem
will attempt to drop and re-establish the connection. During this time, no
incoming or outgoing traffic can be send/received
Note:
The main and backup WAN detection servers have the route to their IP
address bound to the specified link (main or backup). Therefore, main and
backup link detection servers are required to be different. This also means that the
detection servers should not also perform another required function
–
that is, you
should
not
assign the same IPs as used for link detection to DNS server(s), or to be
the target of serial port or GPS data etc.
Fixed WAN IP, Fixed WAN Gateway can be configured using the following settings.
Enabling this feature allocate modem with fix WAN IP with fix WAN Gateway. Dial
failure to restart (default 10 mins) feature along with Ppp Asyncmap can also be
enabled. Enabling dial failure to restart enable modem to run the dial up script
every 10 minutes.
Note:
for “dual both on
-
line”
(a main and backup WAN), you should disable
“Enable Dial Failure to Restart” or the modem
will reboot on extended main
WAN link failure
Force reconnect
Enabling this option forces the Datamax 4G to drop the WAN connection and
then re-establish it at the defined interval.
