Wizard Setup
This chapter provides information on the Wizard Setup screens in the web configurator.
3.1 Wizard Setup Introduction
Use the Wizard Setup screens to configure your system for Internet access settings and fill in the fields with
the information in the Internet Account Information table of the Quick Start Guide. Your ISP may have
already configured some of the fields in the wizard screens for you.
3.2 Encapsulation
Be sure to use the encapsulation method required by your ISP. The Prestige supports the following methods.
3.2.1 PPPoE Encapsulation
PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP.
The Prestige bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an
ATM PVC (Permanent Virtual Circuit) that connects to an ADSL Access Concentrator where the PPP
session terminates. One PVC can support any number of PPP sessions from your LAN. The PPPoE option
is for a dial-up connection using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing access
control systems (for example Radius). 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 you 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 individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or 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
