Configure network interfaces
Select transmit interface using the routing table
When enabled, causes the router to choose the best route from the routing table. If unchecked,
the exit interface will be the interface on which the heartbeat is configured.
Include IMSI information in the Heartbeat message
When enabled, causes the router to include the IMSI of the wireless modem module in the
heartbeat packet.
Include GPS information in the Heartbeat message
When enabled, causes the router to include the GPS co-ordinates in the heartbeat packet.
Generate Ping packets on this interface
When enabled, this setting causes the router to reveal the configuration parameters that enable
the sending of ICMP echo request (ping) packets. You can use this feature as part of a backup
interface strategy.
Send n byte pings to IP host a.b.c.d every h hrs, m mins, s secs
Controls how the ICMP echo requests are generated. The value in the left-hand text box specifies
the number of data bytes in the echo request. Typical values are 32 or 64 octets. The IP host text
box specifies the IP address of the host to which the ping packets are sent. The remaining
parameters specify how often the ping should be sent.
Send pings every h hrs, m mins, s seconds if ping responses are not being received
These three text boxes specify the interval at which to send pings when more than one ping
request is outstanding. When left at the default of 0, this function is disabled.
Switch to sending pings to IP host a.b.c.d after n failures
These parameters allow for more reliable problem detection before failover occurs. If the value
in the first text box is a valid IP address, and the value in the second text box is greater than 0,
when a ping failure is detected on the primary host address, this secondary host is tried. This is
to ensure that should the primary host become unavailable for any reason and stops responding
to the ICMP echo requests, the router will check an alternative IP address before initiating the
failover procedure. The value in the second text box is the number of pings that should be
allowed to fail before checking the secondary IP address.
