Broadband Router User Guide

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.

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.

Routing Example

Router A

(192.168.1.80)

(192.168.0.100)

Segment 1

(192.168.1.xx)

Router B

(192.168.1.90) (192.168.2.70)

Segment 0

(192.168.0.xx)

Broadband

Router

(192.168.0.1)

Segment 2

(192.168.2.xx)

For the LAN shown above, with 2 routers and 3 LAN segments, the required entries would be as follows.
