Multihome additional consecutive addresses
This parameter defines how many additional (consecutive) addresses the ethernet driver will
“own”. For example, if the IP address of the interface was 10.3.20.40, and Multihome
additional consecutive addresses was set to 3, the IP addresses 10.3.20.41, 10.3.20.42 and
10.3.20.43 would also belong to the Ethernet interface.
Enable IGMP on this interface
This parameter is used to enable or disable the Internet Group Management Protocol for this
Ethernet interface.
Enable Bridge on this interface
Bridge mode only applies to models with built in Wi-Fi. If Wi-Fi is enabled, bridge mode
must be enabled on the Eth 0. This will create an Ethernet bridge between the Wi-Fi access
point and the physical Ethernet interface.
Generate Heartbeats on this interface
Enabling this option will display the parameters for Heartbeat packets. These are UDP
packets which can contain status information about the router and can be used in
conjunction with Remote Manager.
Send Heartbeat messages to IP address a.b.c.d every h hrs m mins s seconds
Where:
a.b.c.d specifies the destination IP address for heartbeat packets.
h, m & s specifies how often the router will transmit “heartbeat” packets to the specified
destination in (h) Hours, (m) Minutes and (s) Seconds.
Use interface x,y for the source IP address
By default, heartbeat packets will be sent with the source IP address of the interface on
which they were generated. If the heartbeat is required to be sent via an IPSec tunnel,
this parameter can be used to specify the source IP address of the heartbeat packet to
ensure the source and destination match the eroute selectors.
Select the transmit interface using the routing table
When enabled, the UDP heartbeats will choose the best route from the routing table. If
disabled the exit interface will be interface on which the heartbeat is configured.
Include IMSI information in the Heartbeat message
When enabled, the heartbeat will include the IMSI of the cellular module.
Include GPS information in the Heartbeat message
When enabled and the appropriate GPS hardware is installed, the heartbeat will include
the GPS co-ordinates of the router.
Generate Ping packets on this interface
Enabling this option will display the parameters for enabling auto-pings to be transmitted
from this interface. These pings can be monitored by the interface auto-pings were enabled
on and in the event of no ping reply, the interface can be taken out of service for a specified
amount of time, before allowing the interface to be used again. Another option is to enable
auto-pings on this interface and let the firewall handle taking the interface out of service in
the event of a failure. Both methods are explained in Application Notes on our Technical
Support Documents webpage.
