CHAPTER 9 Overview of Major Capabilities
The Motorola Netopia® Gateway offers simplified setup and management features as well as advanced broadband router capabilities. The following are some of the main features of the Motorola Netopia® Gate- way:
•“Wide Area Network Termination” on page 351
The Gateway combines an ADSL modem with an Internet router. It translates protocols used on the Inter- net to protocols used by home personal computers and eliminates the need for special desktop soft- ware (i.e. PPPoE).
•“Simplified Local Area Network Setup” on page 352
•“Management” on page 353
A Web server built into the Motorola Netopia® Operating System makes setup and maintenance easy using standard browsers. Diagnostic tools facilitate troubleshooting.
•“Security” on page 354
Network Address Translation (NAT), password protection, Stateful Inspection firewall and other
Wide Area Network Termination
PPPoE/PPPoA (Point-to-Point Protocol over Ethernet/ATM)
The PPPoE specification, incorporating the PPP and Ethernet standards, allows your computer(s) to connect to your Service Provider’s network through your Ethernet WAN connection. The Motorola
Service Providers may require the use of PPP authentication protocols such as Challenge Handshake Authentication Protocol (CHAP) or Password Authentication Protocol (PAP). CHAP and PAP use a username and password pair to authenticate users with a PPP server.
A CHAP authentication process works as follows:
1.The password is used to scramble a challenge string.
2.The password is a shared secret, known by both peers.
