Disconnect the link after n failed echo requests
The value in this text box set the number of consecutive failed echo requests that are
allowed before the router terminates the link. When set to zero, this functionality is
disabled, i.e. the router will not terminate the link if the LCP echo requests do not elicit a
response from the remote.
Generate Heartbeats on this interface
When checked, this checkbox reveals the configuration options that control how the router
sends heartbeat packets. Generating a valid configuration enables the router to send
heartbeat packets to the specified destination. Heartbeat packets are UDP packets that
contain various items of information about the router and which may include status
information that may be used to locate its current dynamic IP address. Heartbeats may also
contain GPS position information and mobile telephone module information.
Send Heartbeat messages to IP address a.b.c.d every h hrs, m minutes, s secs
The left-hand text box contains the IP address of the destination for the heartbeat
packets. The remaining text boxes specify the desired interval between sending
heartbeat packets.
Use interface x,y for the source IP address
These two text boxes allow selection of the source interface for the UDP heartbeats.
Selecting an Ethernet source will allow the packets to follow the routing table instead of
being sent out from the PPP interface on which they are set.
Select transmit interface using the routing table
When checked, this checkbox 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 checked, this checkbox causes the router to include the IMSI of the wireless
MODEM module in the heartbeat packet.
Include GPS information in the Heartbeat message
When checked, this checkbox causes the router to include the GPS co-ordinates in the
heartbeat packet.
Generate Ping packets on this interface
When checked, this checkbox causes the router to reveal the configuration parameters that
enable the sending of ICMP echo request (ping) packets. This feature can be used 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
These parameters control 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 zero 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 zero, when a ping failure is detected on the primary host address, this
