LABEL

DESCRIPTION

Destination

This displays the IP address to which this entry applies.

Gateway

This displays the gateway the VDSL Router uses to send traffic to the entry’s destination

address.

Subnet Mask

This displays the subnet mask of the destination net.

Flag

This displays whether the route is up (

U

), the VDSL Router drops packets for this

destination (

Overview

This chapter discusses the VDSL Router’s

WAN

screens. Use these screens to configure your VDSL

Router for Internet access.

A WAN (Wide Area Network) connection is an outside connection to another network or the

Internet. It connects your private networks, such as a LAN (Local Area Network) and other

networks, so that a computer in one location can communicate with computers in other locations.

Figure 14

LAN and WAN

3G (third generation) standards for the sending and receiving of voice, video, and data in a mobile

environment.

You can attach a 3G wireless adapter to the USB port and set the VDSL Router to use this 3G

connection as your WAN or a backup when the wired WAN connection fails.

What You Need to Know

The following terms and concepts may help as you read this chapter.

Encapsulation Method

Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set

up a WAN connection to the Internet, you need to use the same encapsulation method used by your

ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP

over Ethernet), they should also provide a username and password (and service name) for user

authentication.

WAN IP Address

The WAN IP address is an IP address for the VDSL Router, which makes it accessible from an

outside network. It is used by the VDSL Router to communicate with other devices in other

networks. It can be static (fixed) or dynamically assigned by the ISP each time the VDSL Router

tries to access the Internet.

If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and

DNS server IP address(es).

ATM

Asynchronous Transfer Mode (ATM) is a WAN networking technology that provides high-speed data

transfer. ATM uses fixed-size packets of information called cells. With ATM, a high QoS (Quality of

Service) can be guaranteed. ATM uses a connection-oriented model and establishes a virtual circuit

(VC) between Finding Out More

PTM

Packet Transfer Mode (PTM) is packet-oriented and supported by the VDSL2 standard. In PTM,

packets are encapsulated directly in the High-level Data Link Control (HDLC) frames. It is designed

to provide a low-overhead, transparent way of transporting packets over DSL links, as an

alternative to ATM.

3G

3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is

optimized as multiple users share the same channel and bandwidth is only allocated to users when

they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet

access to mobile devices.

IPv6 Introduction

IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The

increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10

38

IP

addresses. The VDSL Router can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks,

and supports IPv6 rapid deployment (6RD).

IPv6 Addressing

The 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This

is an example IPv6 address

2001:0db8:1a2b:0015:0000:0000:1a2f:0000

.

IPv6 addresses can be abbreviated in two ways:

•

Leading zeros in a block can be omitted. So

2001:0db8:1a2b:0015:0000:0000:1a2f:0000

can

be written as

2001:db8:1a2b:15:0:0:1a2f:0

.

•

Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can

only appear once in an IPv6 address. So

2001:0db8:0000:0000:1a2f:0000:0000:0015

can be

written as

2001:0db8::1a2f:0000:0000:0015

,

2001:0db8:0000:0000:1a2f::0015

,

2001:db8::1a2f:0:0:15

or

2001:db8:0:0:1a2f::15

.

IPv6 Prefix and Prefix Length

Similar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An

IPv6 prefix length specifies how many most significant bits (start from the left) in the address

compose the network address. The prefix length is written as “/x” where x is a number. For

example,

2001:db8:1a2b:15::1a2f:0/32

means that the first 32 bits (

2001:db8

) is the subnet prefix.
