CHAPTER 6: WAN Setup
This chapter describes how to configure WAN settings.
6.1 WAN Overview
A WAN (Wide Area Network) is an outside connection to another network or the
Internet.
See the Wizard Setup chapter for more information on the fields in the WAN
screens.
6.2 PPPoE Encapsulation
The ADSL Router supports PPPoE (Point-to-Point Protocol over Ethernet).
PPPoE is an IETF Draft standard (RFC 2516) specifying how a personal
computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.)
connection. 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 ADSL Router (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the ADSL Router does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.
6.3 PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables
secure transfer of data from a remote client to a private server, creating a Virtual
Private Network (VPN) using TCP/IP-based networks.
PPTP supports on-demand, multi-protocol and virtual private networking over
public networks, such as the Internet.
6.4 Traffic Shaping
Traffic Shaping is an agreement between the carrier and the subscriber to
regulate the average rate and “burstiness” or fluctuation of data transmission over
