Routing
This Chapter explains the Routing features of the Internet Router.
Overview
While the ISDN Internet Router includes a standard routing table, this feature can
be completely ignored if you do not have a router in your LAN.
If you DO have a router, it is necessary to configure BOTH the Router and the
Routing table in the ISDN Internet Router correctly, as described in the following
sections.
Router Configuration
It is essential that all IP packets for devices not on the local LAN be passed to the
ISDN Internet Router, so that they can be forwarded to the Internet. To achieve this,
the Routers must be configured to use the ISDN Internet Router as the Default
Route or Default Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the ISDN
Internet Router. This router requires that the Default Route is the ISDN Internet
Router itself. Typically, routers have a special entry for the Default Route. It should
be configured as follows.
Destination IP Ad-
