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
Built-in DHCP and DNS proxy features minimize or eliminate the need to program any network configura-
tion into your home personal computer.
• “Management” on page 353
A Web ser ver 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 built-in
security features prevent unauthorized remote access to your network. Pinholes, default ser ver, and
other features permit access to computers on your home network that you can specify.
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 Ser vice Provider’s network through your Ethernet WAN connection. The Motorola Netopia®-series
Gateway suppor ts PPPoE, eliminating the need to install PPPoE client software on any LAN computers.
Ser vice 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 ser ver.
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.
