3.3.4 PPPoE Encapsulation

The Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). You can use PPPoE encapsulation only
when you're using the Prestige with an xDSL modem as the WAN device.
PPPoE is an IETF Draft standard specifying how a host personal computer interacts with a broadband
modem (i.e. xDSL, cable, wireless, etc.) to achieve access to high-speed data networks. It preserves the
existing Microsoft Dial-Up Networking experience and requires no new learning or procedures.
For the service provider, PPPoE offers an access and authentication method that works with existing access
control systems (e.g., Radius). For the user, PPPoE provides a login and authentication method that the
existing Microsoft Dial-Up Networking software can activate, and therefore requires no new learning or
procedures for Windows users.
One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function
known as dynamic service selection. This enables the service provider to easily create and offer new IP
services for specific users.
Operationally, PPPoE saves significant effort for both the end user and ISP/carrier, as it requires no specific
configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the Prestige (rather than individual computers), the computers on the
LAN do not need PPPoE software installed, since the Prestige does that part of the task. Furthermore, with
NAT, all of the LAN's computers will have access.
If you enable PPPoE in menu 4, you will see the next screen. For more information on PPPoE, please refer to
the PPPoE Appendix.
