Netopia R6000 Series Routers offer the ability for PPP to reconfigure the router's Ethernet LAN when
establishing an unnumbered, non-NAT connection.
This allows a central site router to supply an entire IP subnet, rather than a single IP address, for use by a
Netopia router. If the applicable Connection Profile specifies an unnumbered, non-NAT connection and Negotiate
LAN IP Addr/Mask is set to On, PPP will attempt to negotiate both an IP Address and subnet mask.
Note: Once the router has reconfigured the address serving pool only to conform to the negotiated subnet, you
can adjust the base or extent of the pool and reboot the router. Your adjustments will not be overwritten when
the connection is next renegotiated because the router only reconfigures the address serving pool if it lies
outside the negotiated subnet.
The router does not adjust any address serving parameters other than the base and extent of the address
serving pool. This allows you to otherwise configure address serving as you please using the normal address
serving configuration items. For example, if you disable address serving, the router will not enable address
serving when it reconfigures the address serving pool.
To enable PPP Ethernet LAN configuration, navigate to the IP Profile Parameters screen of the Connection Profile
you want to use. This can be either the Easy Setup Profile or any other Connection Profile you have added.
The IP Profile Parameters screen for a Connection Profile displays a Negotiate LAN IP Addr/Mask toggle:
Address Translation Enabled:
IP Addressing...
Negotiate LAN IP Addr/Mask:
Remote IP Address:
Remote IP Mask:

Configure IP requirements for a remote network connection here.
This toggle is visible only if the profile's Data Link Encapsulation is set to PPP, the Address Translation
Enabled toggle is set to No and IP Addressing is set to Unnumbered. The default value is No.
RIP Profile Options is not visible if Negotiate LAN IP Addr/Mask is set to Yes and the Remote IP Mask is set
to 0.0.0.0. See "RIP Profile Options" on page 8-16
