Local Router
The local router is the Router installed on the same LAN segment as the ADSL VoIP Router.
This router requires that the Default Route is the ADSL VoIP 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 ADSL VoIP Router.
Metric 1
Other Routers on the Local LAN
Other routers on the local LAN must use the ADSL VoIP Router's Local Router as the Default
Route. The entries will be the same as the ADSL VoIP Router's local router, with the exception
of the Gateway IP Address.
• For a router with a direct connection to the ADSL VoIP Router's local Router, the Gateway
IP Address is the address of the ADSL VoIP Router's local router.
• For routers which must forward packets to another router before reaching the ADSL VoIP
Router's local router, the Gateway IP Address is the address of the intermediate router.
