4.3.1.B Default LAN Route
The Default LAN Route is a special static route that can be useful when there are a large number of networks
accessible through a gateway. All IP packets received having a destination IP address without an explicit routing-
table entry will be sent to the default route.
To define the Concentrator’s default LAN route:
1. Select Default Route (LAN) from the IP Configuration Menu. For a Concentrator right out of the box,
this screen will appear:
2. To enable a default route, you will need to change the Status from
DISABLED
to one of the following:
•
SET TO NEXT HOP
With this setting, you will need to specify a Next Hop IP address for your default route
(you’ll do this in step 3).
•
SET TO SELF
With this setting, the Concentrator will ARP directly for all IP addresses for which it does not have a
route. This requires routers on the Concentrator’s LAN segment to have proxy ARP enabled in order
for the Concentrator to reach subnets behind the routers. If you select Set to Self, no additional screen
changes are needed here. Proceed to step 5.
3. If you have changed the status to Set to Next Hop, enter the IP address of the Next Hop gateway that
provides access to the target default network. The Next Hop must be on the network connected to
the defined LAN interface.
