Route Info Screen
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 (
!
), the route uses a gateway (

), the target is a host (
H
), reinstate route for
dynamic routing (
R
), the route was dynamically installed by redirect (

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.

•
Use the
WAN Service
screens to view, remove or add a WAN interface. You can also configure
the WAN settings on the VDSL Router for Internet access (
Section 4.4 on page 81

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.
