Router Configuration
It is essential that all IP packets for devices not on the local LAN be passed to the Broadband
Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this,
the local LAN must be configured to use the Broadband Router as the Default Route or Default
Gateway.
Local Router
The local router is the Router installed on the same LAN segment as the Broadband Router.
This router requires that the Default Route is the Broadband Router itself. Typically, routers
have a special entry for the Default Route. It should be configured as follows.
Destination IP Address Normally 0.0.0.0, but check your router
documentation.
Network Mask Normally 0.0.0.0, but check your router
documentation.
Gateway IP Address The IP Address of the Broadband Router.
Metric 1
Other Routers on the Local LAN
Other routers on the local LAN must use the Broadband Router's Local Router as the Default
Route. The entries will be the same as the Broadband Router's local router, with the exception
of the Gateway IP Address.
• For a router with a direct connection to the Broadband Router's local Router, the Gateway
IP Address is the address of the Broadband Router's local router.
• For routers which must forward packets to another router before reaching the Broadband
Router's local router, the Gateway IP Address is the address of the intermediate router.
