CHAPTER 12
Certificate
12.1 Overview
The ZyXEL Device can use certificates (also called digital IDs) to authenticate
users. Certificates are based on public-private key pairs. A certificate contains the
certificate owner’s identity and public key. Certificates provide a way to exchange
public keys for use in authentication.
12.1.1 What You Can Do in this Chapter
•The Trusted CA screen lets you save the certificates of trusted CAs to the
ZyXEL Device (Section 12.3 on page 156).
12.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
Certification Authority
A Certification Authority (CA) issues certificates and guarantees the identity of
each certificate owner. There are commercial certification authorities like
CyberTrust or VeriSign and government certification authorities. The certification
authority uses its private key to sign certificates. Anyone can then use the
certification authority's public key to verify the certificates. You can use the ZyXEL
Device to generate certification requests that contain identifying information and
public keys and then send the certification requests to a certification authority.
Certificate File Format
The certification authority certificate that you want to import has to be in one of
these file formats:
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses 64
ASCII characters to convert a binary X.509 certificate into a printable form.
Chapter 12 Certificate

12.3 The Trusted CA Screen
Click Security > Certificates to open the following screen. This screen displays a
summary list of certificates of the certification authorities that you have set the
ZyXEL Device to accept as trusted. The ZyXEL Device accepts any valid certificate

CHAPTER 13
Static Route
13.1 Overview
The ZyXEL Device usually uses the default gateway to route outbound traffic from
computers on the LAN to the Internet. To have the ZyXEL Device send data to
devices not reachable through the default gateway, use static routes.
For example, the next figure shows a computer (A) connected to the ZyXEL
Device’s LAN interface. The ZyXEL Device routes most traffic from A to the
Internet through the ZyXEL Device’s default gateway (R1). You create one static
route to connect to services offered by your ISP behind router R2. You create
another static route to communicate with a separate network behind a router R3
connected to the LAN.

CHAPTER 14
Quality of Service (QoS)
14.1 Overview
Use the QoS screen to set up your ZyXEL Device to use QoS for traffic
management.
Quality of Service (QoS) refers to both a network’s ability to deliver data with
minimum delay, and the networking methods used to control bandwidth. QoS
allows the ZyXEL Device to group and prioritize application traffic and fine-tune
network performance.
Without QoS, all traffic data are equally likely to be dropped when the network is
congested. This can cause a reduction in network performance and make the
network inadequate for time-critical applications such as video-on-demand.
The ZyXEL Device assigns each packet a priority and then queues the packet
accordingly. Packets assigned with a high priority are processed more quickly than
those with low priorities if there is congestion, allowing time-sensitive applications
to flow more smoothly. Time-sensitive applications include both those that require
a low level of latency (delay) and a low level of jitter (variations in delay) such as
Voice over IP (VoIP) or Internet gaming, and those for which jitter alone is a
problem such as Internet radio or streaming video.
In the following figure, your Internet connection has an upstream transmission
speed of 50 Mbps. You configure a classifier to assign the highest priority queue
(6) to VoIP traffic from the LAN interface, so that voice traffic would not get
delayed when there is network congestion. Traffic from the boss’s IP address
(192.168.1.23 for example) is mapped to queue 5. Traffic that does not match

these two classes are assigned priority queue based on the internal QoS mapping
table on the ZyXEL Device.
Figure 78 QoS Example
14.1.1 What You Can Do in the QoS Screens
•Use the General screen (Section 14.2 on page 167) to enable QoS on the
ZyXEL Device, and specify the type of scheduling.
•Use the QoS Summary List screen (Section 14.2.1 on page 168) to check the
summary of QoS rules and actions you configured for the ZyXEL Device.
•Use the Queue Setup screen (Section 14.3 on page 168) to configure QoS
settings on the ZyXEL Device.
•Use the Class Setup screen (Section 14.4 on page 170) to configure QoS
settings on the ZyXEL Device.
14.1.2 What You Need to Know About QoS
802.1p
QoS is used to prioritize source-to-destination traffic flows. All packets in the same
flow are given the same priority. 802.1p is a way of managing traffic in a network
by grouping similar types of traffic together and treating each type as a class. You
can use 802.1p to give different priorities to different packet types.
Tagging and Marking
In a QoS class, you can configure whether to add or change the DiffServ Code
Point (DSCP) value and IEEE 802.1p priority level in a matched packet. When the
packet passes through a compatible network, the networking device, such as a
backbone switch, can provide specific treatment or service based on the tag or
marker.

14.5.1 IEEE 802.1p
IEEE 802.1p specifies the user priority field and defines up to eight separate traffic
types. The following table describes the traffic types defined in the IEEE 802.1d
standard (which incorporates the 802.1p).
14.5.2 IP Precedence
Similar to IEEE 802.1p prioritization at layer-2, you can use IP precedence to
prioritize packets in a layer-3 network. IP precedence uses three bits of the eight-
bit ToS (Type of Service) field in the IP header. There are eight classes of services
(ranging from zero to seven) in IP precedence. Zero is the lowest priority level and
seven is the highest.
14.5.3 Automatic Priority Queue Assignment
If you enable QoS on the ZyXEL Device, the ZyXEL Device can automatically base
on the IEEE 802.1p priority level, IP precedence and/or packet length to assign
priority to traffic which does not match a class.
The following table shows you the internal layer-2 and layer-3 QoS mapping on
the ZyXEL Device. On the ZyXEL Device, traffic assigned to higher priority queues

Level 7 Typically used for network control traffic such as router configuration
messages.
Level 6 Typically used for voice traffic that is especially sensitive to jitter (jitter is the
variations in delay).
Level 5 Typically used for video that consumes high bandwidth and is sensitive to
jitter.
Level 4 Typically used for controlled load, latency-sensitive traffic such as SNA
(Systems Network Architecture) transactions.
Level 3 Typically used for “excellent effort” or better than best effort and would
include important business traffic that can tolerate some delay.
Level 2 This is for “spare bandwidth”.
Level 1 This is typically used for non-critical “background” traffic such as bulk
transfers that are allowed but that should not affect other applications and
users.
Level 0 Typically used for best-effort traffic.

CHAPTER 15
Dynamic DNS Setup
15.1 Overview
Dynamic DNS allows you to update your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-
SeeMe, etc.). You can also access your FTP server or Web site on your own
computer using a domain name (for instance myhost.dhs.org, where myhost is a
name of your choice) that will never change instead of using an IP address that
changes each time you reconnect. Your friends or relatives will always be able to
call you even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP
server that would still like to have a domain name. The Dynamic DNS service
provider will give you a password or key.
15.1.1 What You Can Do in the DDNS Screen
Use the Dynamic DNS screen (Section 15.2 on page 176) to enable DDNS and
configure the DDNS settings on the ZyXEL Device.
15.1.2 What You Need To Know About DDNS
DYNDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be
aliased to the same IP address as yourhost.dyndns.org. This feature is useful if
you want to be able to use, for example, www.yourhost.dyndns.org and still reach
your hostname.

one (SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP
management operation.
Figure 88 SNMP Management Model
An SNMP managed network consists of two main types of component: agents and
a manager.
An agent is a management software module that resides in a managed device (the
ZyXEL Device). An agent translates the local management information from the
managed device into a form compatible with SNMP. The manager is the console
through which network administrators perform network management functions. It
executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each
piece of information to be collected about a device. Examples of variables include
such as number of packets received, node port status etc. A Management
Information Base (MIB) is a collection of managed objects. SNMP allows a
manager and agents to communicate for the purpose of accessing these objects.

If an outside user attempts to probe an unsupported port on your ZyXEL Device,
an ICMP response packet is automatically returned. This allows the outside user to
know the ZyXEL Device exists. Your ZyXEL Device supports anti-probing, which
prevents the ICMP response packet from being sent. This keeps outsiders from
discovering your ZyXEL Device when unsupported ports are probed.
Note: If you want your device to respond to pings and requests for unauthorized
services, you will also need to configure the firewall accordingly by disabling
SPI.

Chapter 17 Universal Plug-and-Play (UPnP)
P-660HN-Tx User’s Guide 185
CHAPTER 17
Universal Plug-and-Play (UPnP)
17.1 Overview
Universal Plug and Play (UPnP) is a distributed, open networking standard that
uses TCP/IP for simple peer-to-peer network connectivity between devices. A
UPnP device can dynamically join a network, obtain an IP address, convey its
capabilities and learn about other devices on the network. In turn, a device can
leave a network smoothly and automatically when it is no longer in use.
17.1.1 What You Can Do in the UPnP Screen
Use the UPnP screen (Section 17.2 on page 187) to enable UPnP on the ZyXEL
Device and allow UPnP-enabled applications to automatically configure the ZyXEL
Device.
17.1.2 What You Need to Know About UPnP
Identifying UPnP Devices
UPnP hardware is identified as an icon in the Network Connections folder
(Windows XP). Each UPnP compatible device installed on your network will appear
as a separate icon. Selecting the icon of a UPnP device will allow you to access the
information and properties of that device.
NAT Traversal
UPnP NAT traversal automates the process of allowing an application to operate
through NAT. UPnP network devices can automatically configure network
addressing, announce their presence in the network to other UPnP devices and
enable exchange of simple product and service descriptions. NAT traversal allows
the following:
• Dynamic port mapping
• Learning public IP addresses
Chapter 17 Universal Plug-and-Play (UPnP)
P-660HN-Tx User’s Guide
186
•Assigning lease times to mappings
Windows Messenger is an example of an application that supports NAT traversal
and UPnP.
See the NAT chapter for more information on NAT.
Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own
services and opening firewall ports may present network security issues. Network
information and configuration may also be obtained and modified by users in some
network environments.
When a UPnP device joins a network, it announces its presence with a multicast
message. For security reasons, the ZyXEL Device allows multicast messages on
the LAN only.
All UPnP-enabled devices may communicate freely with each other without
additional configuration. Disable UPnP if this is not your intention.
UPnP and ZyXEL
ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum
UPnP™ Implementers Corp. (UIC). ZyXEL's UPnP implementation supports
Internet Gateway Device (IGD) 1.0.
See the following sections for examples of installing and using UPnP.

login screen without entering the ZyXEL Device's IP address
(although you must still enter the password to access the web
configurator).
Allow users to make
configuration changes
through UPnP
Select this check box to allow UPnP-enabled applications to
automatically configure the ZyXEL Device so that they can
communicate through the ZyXEL Device, for example by using
NAT traversal, UPnP applications automatically reserve a NAT
forwarding port in order to communicate with another UPnP
enabled device; this eliminates the need to manually configure
port forwarding for the UPnP enabled application.

DSL Line
Status
Click this to view statistics about the DSL connections.
noise margin downstream is the signal to noise ratio for the
downstream part of the connection (coming into the ZyXEL Device from
the ISP). It is measured in decibels. The higher the number the more
signal and less noise there is.
output power upstream is the amount of power (in decibels) that the
ZyXEL Device is using to transmit to the ISP.
attenuation downstream is the reduction in amplitude (in decibels) of
the DSL signal coming into the ZyXEL Device from the ISP.
Discrete Multi-Tone (DMT) modulation divides up a line’s bandwidth into
sub-carriers (sub-channels) of 4.3125 KHz each called tones. The rest of
the display is the line’s bit allocation. This is displayed as the number (in
hexadecimal format) of bits transmitted for each tone. This can be used
to determine the quality of the connection, whether a given sub-carrier
loop has sufficient margins to support certain ADSL transmission rates,
and possibly to determine whether particular specific types of
interference or line attenuation exist. Refer to the ITU-T G.992.1
recommendation for more information on DMT.
The better (or shorter) the line, the higher the number of bits transmitted
for a DMT tone. The maximum number of bits that can be transmitted per
DMT tone is 15. There will be some tones without any bits as there has to
be space between the upstream and downstream channels.

address. Use NAT to convert your public IP address(es) to multiple
private IP addresses for the computers on your network.
Port Forwarding If you have a server (mail or web server for example) on your
network, you can use this feature to let people access it from the
Internet.
DHCP (Dynamic Host
Configuration
Protocol)
Use this feature to have the ZyXEL Device assign IP addresses, an
IP default gateway and DNS servers to computers on your
network. Your device can also act as a surrogate DHCP server
(DHCP Relay) where it relays IP address assignment from the
actual real DHCP server to the clients.
DHCPv6 Use this feature to have the ZyXEL Device assign IPv6 addresses,
an IPv6 default gateway and IPv6 DNS servers to computers on
your network.
Dynamic DNS
Support
With Dynamic DNS (Domain Name System) support, you can use
a fixed URL, www.zyxel.com for example, with a dynamic IP
address. You must register for this service with a Dynamic DNS
service provider.
IP Multicast IP multicast is used to send traffic to a specific group of
computers. The ZyXEL Device supports versions 1 and 2 of IGMP
(Internet Group Management Protocol) used to join multicast
groups (see RFC 2236).
IPv6 Multicast IPv6 multicast is used to send traffic to a specific group of
computers. The ZyXEL Device supports MLD (Multicast Listener
Discovery) used to join IPv6 multicast groups (see RFC 2236).

Play (UPnP)
A UPnP-enabled device can dynamically join a network, obtain an
IP address and convey its capabilities to other devices on the
network.
Firewall Your device has a stateful inspection firewall with DoS (Denial of
Service) protection. By default, when the firewall is activated, all
incoming traffic from the WAN to the LAN is blocked unless it is
initiated from the LAN. The firewall supports TCP/UDP inspection,
DoS detection and prevention, real time alerts, reports and logs.
URL Filtering URL filtering allows you to block access to Internet web sites of
certain URL that you specify.
IP and IPv6 Filtering IP/MAC and IPv6 filtering allows you to block traffic by IP
addresses, MAC addresses and IPv6 addresses.
QoS (Quality of
Service)
You can efficiently manage traffic on your network by reserving
bandwidth and giving priority to certain types of traffic and/or to
particular computers.
Remote Management This allows you to decide whether a service (HTTP or FTP traffic for
example) from a computer on a network (LAN or WAN for
example) can access the ZyXEL Device.
PPPoE Support

APPENDIX A
Setting up Your Computer’s IP
Address
All computers must have a 10M or 100M Ethernet adapter card and TCP/IP
installed.
Windows 95/98/Me/NT/2000/XP/Vista, Macintosh OS 7 and later operating
systems and all versions of UNIX/LINUX include the software components you
need to install and use TCP/IP on your computer. Windows 3.1 requires the
purchase of a third-party TCP/IP application package.
TCP/IP should already be installed on computers using Windows NT/2000/XP,
Macintosh OS 7 and later operating systems.
After the appropriate TCP/IP components are installed, configure the TCP/IP
settings in order to "communicate" with your network.
If you manually assign IP information instead of using dynamic assignment, make
sure that your computers have IP addresses that place them in the same subnet
as the ZyXEL Device’s LAN port.

APPENDIX B
IP Addresses and Subnetting
This appendix introduces IP addresses and subnet masks.
IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to
communicate across the network. These networking devices are also known as
hosts.
Subnet masks determine the maximum number of possible hosts on a network.
You can also use subnet masks to divide one network into multiple sub-networks.
Introduction to IP Addresses
One part of the IP address is the network number, and the other part is the host
ID. In the same way that houses on a street share a common street name, the
hosts on a network share a common network number. Similarly, as each house
has its own house number, each host on the network has its own unique
identifying number - the host ID. Routers use the network number to send packets
to the correct network, while the host ID determines to which host on the network
the packets are delivered.
Structure
An IP address is made up of four parts, written in dotted decimal notation (for
example, 192.168.1.1). Each of these four parts is known as an octet. An octet is
an eight-digit binary number (for example 11000000, which is 192 in decimal
notation).
Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or
0 to 255 in decimal.
Appendix B IP Addresses and Subnetting
P-660HN-Tx User’s Guide
260
The following figure shows an example IP address in which the first three octets
(192.168.1) are the network number, and the fourth octet (16) is the host ID.
Figure 143 Network Number and Host ID
How much of the IP address is the network number and how much is the host ID
varies according to the subnet mask.
Subnet Masks
A subnet mask is used to determine which bits are part of the network number,
and which bits are part of the host ID (using a logical AND operation). The term
“subnet” is short for “sub-network”.
A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the
corresponding bit in the IP address is part of the network number. If a bit in the
subnet mask is “0” then the corresponding bit in the IP address is part of the host
ID.
The following example shows a subnet mask identifying the network number (in
bold text) and host ID of an IP address (192.168.1.2 in decimal).

Appendix B IP Addresses and Subnetting
P-660HN-Tx User’s Guide 261
By convention, subnet masks always consist of a continuous sequence of ones
beginning from the leftmost bit of the mask, followed by a continuous sequence of
zeros, for a total number of 32 bits.
Subnet masks can be referred to by the size of the network number part (the bits
with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the
mask are ones and the remaining 24 bits are zeroes.
Subnet masks are expressed in dotted decimal notation just like IP addresses. The
following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit
and 29-bit subnet masks.
Network Size
The size of the network number determines the maximum number of possible
hosts you can have on your network. The larger the number of network number
bits, the smaller the number of remaining host ID bits.
An IP address with host IDs of all zeros is the IP address of the network
(192.168.1.0 with a 24-bit subnet mask, for example). An IP address with host
IDs of all ones is the broadcast address for that network (192.168.1.255 with a
24-bit subnet mask, for example).
As these two IP addresses cannot be used for individual hosts, calculate the
maximum number of possible hosts in a network as follows:

Notation
Since the mask is always a continuous number of ones beginning from the left,
followed by a continuous number of zeros for the remainder of the 32 bit mask,
you can simply specify the number of ones instead of writing the value of each
octet. This is usually specified by writing a “/” followed by the number of bits in
the mask after the address.
For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask
255.255.255.128.
The following table shows some possible subnet masks using both notations.
Subnetting
You can use subnetting to divide one network into multiple sub-networks. In the
following example a network administrator creates two sub-networks to isolate a
group of servers from the rest of the company network for security reasons.
In this example, the company network address is 192.168.1.0. The first three
octets of the address (192.168.1) are the network number, and the remaining
octet is the host ID, allowing a maximum of 28 – 2 or 254 possible hosts.

The following figure shows the company network before subnetting.
Figure 144 Subnetting Example: Before Subnetting
You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into
two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or
/25).
The “borrowed” host ID bit can have a value of either 0 or 1, allowing two
subnets; 192.168.1.0 /25 and 192.168.1.128 /25.
The following figure shows the company network after subnetting. There are now
two sub-networks, A and B.

Appendix B IP Addresses and Subnetting
P-660HN-Tx User’s Guide
264
In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of
27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself,
all ones is the subnet’s broadcast address).
192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127
with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP
address that can be assigned to an actual host for subnet A is 192.168.1.1 and
the highest is 192.168.1.126.
Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.
Example: Four Subnets
The previous example illustrated using a 25-bit subnet mask to divide a 24-bit
address into two subnets. Similarly, to divide a 24-bit address into four subnets,
you need to “borrow” two host ID bits to give four possible combinations (00, 01,
10 and 11). The subnet mask is 26 bits
(11111111.11111111.11111111.11000000) or 255.255.255.192.
Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a
host ID of all zeroes is the subnet itself, all ones is the subnet’s broadcast
address).

addresses, follow their instructions in selecting the IP addresses and the subnet
mask.
If the ISP did not explicitly give you an IP network number, then most likely you
have a single user account and the ISP will assign you a dynamic IP address when
the connection is established. If this is the case, it is recommended that you select
a network number from 192.168.0.0 to 192.168.255.0. The Internet Assigned
Number Authority (IANA) reserved this block of addresses specifically for private
use; please do not use any other number unless you are told otherwise. You must
also enable Network Address Translation (NAT) on the ZyXEL Device.
Once you have decided on the network number, pick an IP address for your ZyXEL
Device that is easy to remember (for instance, 192.168.1.1) but make sure that
no other device on your network is using that IP address.
The subnet mask specifies the network number portion of an IP address. Your
ZyXEL Device will compute the subnet mask automatically based on the IP
address that you entered. You don't need to change the subnet mask computed by
the ZyXEL Device unless you are instructed to do otherwise.
Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are
isolated from the Internet (running only between two branch offices, for example)
you can assign any IP addresses to the hosts without problems. However, the
Internet Assigned Numbers Authority (IANA) has reserved the following three
blocks of IP addresses specifically for private networks:
• 10.0.0.0 — 10.255.255.255
• 172.16.0.0 — 172.31.255.255
• 192.168.0.0 — 192.168.255.255
You can obtain your IP address from the IANA, from an ISP, or it can be assigned
from a private network. If you belong to a small organization and your Internet
access is through an ISP, the ISP can provide you with the Internet addresses for
your local networks. On the other hand, if you are part of a much larger
organization, you should consult your network administrator for the appropriate IP
addresses.
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment,
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,
Guidelines for Management of IP Address Space.

Wireless LANs
Wireless LAN Topologies
This section discusses ad-hoc and infrastructure wireless LAN topologies.
Ad-hoc Wireless LAN Configuration
The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects
a set of computers with wireless adapters (A, B, C). Any time two or more wireless
adapters are within range of each other, they can set up an independent network,
which is commonly referred to as an ad-hoc network or Independent Basic Service
Set (IBSS). The following diagram shows an example of notebook computers
using wireless adapters to form an ad-hoc wireless LAN.
Figure 156 Peer-to-Peer Communication in an Ad-hoc Network
BSS
A Basic Service Set (BSS) exists when all communications between wireless
clients or between a wireless client and a wired network client go through one
access point (AP).
Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is
enabled, wireless client A and B can access the wired network and communicate
Appendix D Wireless LANs
P-660HN-Tx User’s Guide
280
with each other. When Intra-BSS is disabled, wireless client A and B can still
access the wired network but cannot communicate with each other.
Figure 157 Basic Service Set
ESS
An Extended Service Set (ESS) consists of a series of overlapping BSSs, each
containing an access point, with each access point connected together by a wired
network. This wired connection between APs is called a Distribution System (DS).
This type of wireless LAN topology is called an Infrastructure WLAN. The Access
Points not only provide communication with the wired network but also mediate
wireless network traffic in the immediate neighborhood.
Appendix D Wireless LANs
P-660HN-Tx User’s Guide 281
An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and
their associated wireless clients within the same ESS must have the same ESSID
in order to communicate.
Figure 158 Infrastructure WLAN
Channel
A channel is the radio frequency(ies) used by wireless devices to transmit and
receive data. Channels available depend on your geographical area. You may have
a choice of channels (for your region) so you should use a channel different from
an adjacent AP (access point) to reduce interference. Interference occurs when
radio signals from different access points overlap causing interference and
degrading performance.
Adjacent channels partially overlap however. To avoid interference due to overlap,
your AP should be on a channel at least five channels away from a channel that an
adjacent AP is using. For example, if your region has 11 channels and an adjacent
AP is using channel 1, then you need to select a channel between 6 or 11.
RTS/CTS
A hidden node occurs when two stations are within range of the same access
point, but are not within range of each other. The following figure illustrates a
Appendix D Wireless LANs
P-660HN-Tx User’s Guide
282
hidden node. Both stations (STA) are within range of the access point (AP) or
wireless gateway, but out-of-range of each other, so they cannot "hear" each
other, that is they do not know if the channel is currently being used. Therefore,
they are considered hidden from each other.
Figure 159 RTS/CTS
When station A sends data to the AP, it might not know that the station B is
already using the channel. If these two stations send data at the same time,
collisions may occur when both sets of data arrive at the AP at the same time,
resulting in a loss of messages for both stations.
RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS
defines the biggest size data frame you can send before an RTS (Request To
Send)/CTS (Clear to Send) handshake is invoked.
When a data frame exceeds the RTS/CTS value you set (between 0 to 2432
bytes), the station that wants to transmit this frame must first send an RTS
(Request To Send) message to the AP for permission to send it. The AP then
responds with a CTS (Clear to Send) message to all other stations within its range
to notify them to defer their transmission. It also reserves and confirms with the
requesting station the time frame for the requested transmission.
Stations can send frames smaller than the specified RTS/CTS directly to the AP
without the RTS (Request To Send)/CTS (Clear to Send) handshake.
You should only configure RTS/CTS if the possibility of hidden nodes exists on
your network and the "cost" of resending large frames is more than the extra
network overhead involved in the RTS (Request To Send)/CTS (Clear to Send)
handshake.
If the RTS/CTS value is greater than the Fragmentation Threshold value (see
next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never
occur as data frames will be fragmented before they reach RTS/CTS size.
Note: Enabling the RTS Threshold causes redundant network overhead that could
negatively affect the throughput performance instead of providing a remedy.
Appendix D Wireless LANs
P-660HN-Tx User’s Guide 283
Fragmentation Threshold
A Fragmentation Threshold is the maximum data fragment size (between 256
and 2432 bytes) that can be sent in the wireless network before the AP will
fragment the packet into smaller data frames.
A large Fragmentation Threshold is recommended for networks not prone to
interference while you should set a smaller threshold for busy networks or
networks that are prone to interference.
If the Fragmentation Threshold value is smaller than the RTS/CTS value (see
previously) you set then the RTS (Request To Send)/CTS (Clear to Send)
handshake will never occur as data frames will be fragmented before they reach
RTS/CTS size.
Preamble Type
Preamble is used to signal that data is coming to the receiver. Short and long refer
to the length of the synchronization field in a packet.
Short preamble increases performance as less time sending preamble means
more time for sending data. All IEEE 802.11 compliant wireless adapters support
long preamble, but not all support short preamble.
Use long preamble if you are unsure what preamble mode other wireless devices
on the network support, and to provide more reliable communications in busy
wireless networks.
Use short preamble if you are sure all wireless devices on the network support it,
and to provide more efficient communications.
Use the dynamic setting to automatically use short preamble when all wireless
devices on the network support it, otherwise the ZyXEL Device uses long
preamble.
Note: The wireless devices MUST use the same preamble mode in order to
communicate.
IEEE 802.11g Wireless LAN
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an
IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point
(and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has
Appendix D Wireless LANs
P-660HN-Tx User’s Guide
284
several intermediate rate steps between the maximum and minimum data rates.
The IEEE 802.11g data rate and modulation are as follows:
Wireless Security Overview
Wireless security is vital to your network to protect wireless communication
between wireless clients, access points and the wired network.
Wireless security methods available on the ZyXEL Device are data encryption,
wireless client authentication, restricting access by device MAC address and hiding
the ZyXEL Device identity.
The following figure shows the relative effectiveness of these wireless security
methods available on your ZyXEL Device.
Note: You must enable the same wireless security settings on the ZyXEL Device and
on all wireless clients that you want to associate with it.

Appendix D Wireless LANs
P-660HN-Tx User’s Guide 285
IEEE 802.1x
In June 2001, the IEEE 802.1x standard was designed to extend the features of
IEEE 802.11 to support extended authentication as well as providing additional
accounting and control features. It is supported by Windows XP and a number of
network devices. Some advantages of IEEE 802.1x are:
• User based identification that allows for roaming.
• Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138,
2139) for centralized user profile and accounting management on a network
RADIUS server.
• Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows
additional authentication methods to be deployed with no changes to the access
point or the wireless clients.
RADIUS
RADIUS is based on a client-server model that supports authentication,
authorization and accounting. The access point is the client and the server is the
RADIUS server. The RADIUS server handles the following tasks:
• Authentication
Determines the identity of the users.
• Authorization
Determines the network services available to authenticated users once they are
connected to the network.
•Accounting
Keeps track of the client’s network activity.
RADIUS is a simple package exchange in which your AP acts as a message relay
between the wireless client and the network RADIUS server.
Types of RADIUS Messages
The following types of RADIUS messages are exchanged between the access point
and the RADIUS server for user authentication:
• Access-Request
Sent by an access point requesting authentication.
• Access-Reject
Sent by a RADIUS server rejecting access.
• Access-Accept
Sent by a RADIUS server allowing access.
Appendix D Wireless LANs
P-660HN-Tx User’s Guide
286
•Access-Challenge
Sent by a RADIUS server requesting more information in order to allow access.
The access point sends a proper response from the user and then sends another
Access-Request message.
The following types of RADIUS messages are exchanged between the access point
and the RADIUS server for user accounting:
•Accounting-Request
Sent by the access point requesting accounting.
• Accounting-Response
Sent by the RADIUS server to indicate that it has started or stopped accounting.
In order to ensure network security, the access point and the RADIUS server use a
shared secret key, which is a password, they both know. The key is not sent over
the network. In addition to the shared key, password information exchanged is
also encrypted to protect the network from unauthorized access.
Types of EAP Authentication
This section discusses some popular authentication types: EAP-MD5, EAP-TLS,
EAP-TTLS, PEAP and LEAP. Your wireless LAN device may not support all
authentication types.
EAP (Extensible Authentication Protocol) is an authentication protocol that runs on
top of the IEEE 802.1x transport mechanism in order to support multiple types of
user authentication. By using EAP to interact with an EAP-compatible RADIUS
server, an access point helps a wireless station and a RADIUS server perform
authentication.
The type of authentication you use depends on the RADIUS server and an
intermediary AP(s) that supports IEEE 802.1x.
For EAP-TLS authentication type, you must first have a wired connection to the
network and obtain the certificate(s) from a certificate authority (CA). A certificate
(also called digital IDs) can be used to authenticate users and a CA issues
certificates and guarantees the identity of each certificate owner.
EAP-MD5 (Message-Digest Algorithm 5)
MD5 authentication is the simplest one-way authentication method. The
authentication server sends a challenge to the wireless client. The wireless client
‘proves’ that it knows the password by encrypting the password with the challenge
and sends back the information. Password is not sent in plain text.
Appendix D Wireless LANs
P-660HN-Tx User’s Guide 287
However, MD5 authentication has some weaknesses. Since the authentication
server needs to get the plaintext passwords, the passwords must be stored. Thus
someone other than the authentication server may access the password file. In
addition, it is possible to impersonate an authentication server as MD5
authentication method does not perform mutual authentication. Finally, MD5
authentication method does not support data encryption with dynamic session
key. You must configure WEP encryption keys for data encryption.
EAP-TLS (Transport Layer Security)
With EAP-TLS, digital certifications are needed by both the server and the wireless
clients for mutual authentication. The server presents a certificate to the client.
After validating the identity of the server, the client sends a different certificate to
the server. The exchange of certificates is done in the open before a secured
tunnel is created. This makes user identity vulnerable to passive attacks. A digital
certificate is an electronic ID card that authenticates the sender’s identity.
However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle
certificates, which imposes a management overhead.
EAP-TTLS (Tunneled Transport Layer Service)
EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for
only the server-side authentications to establish a secure connection. Client
authentication is then done by sending username and password through the
secure connection, thus client identity is protected. For client authentication, EAP-
TTLS supports EAP methods and legacy authentication methods such as PAP,
CHAP, MS-CHAP and MS-CHAP v2.
PEAP (Protected EAP)
Like EAP-TTLS, server-side certificate authentication is used to establish a secure
connection, then use simple username and password methods through the
secured connection to authenticate the clients, thus hiding client identity.
However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2
and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is
implemented only by Cisco.
LEAP
LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of
IEEE 802.1x.

Dynamic WEP Key Exchange
The AP maps a unique key that is generated with the RADIUS server. This key
expires when the wireless connection times out, disconnects or reauthentication
times out. A new WEP key is generated each time reauthentication is performed.
If this feature is enabled, it is not necessary to configure a default encryption key
in the wireless security configuration screen. You may still configure and store
keys, but they will not be used while dynamic WEP is enabled.
Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange
For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and
PEAP) use dynamic keys for data encryption. They are often deployed in corporate
environments, but for public deployment, a simple user name and password pair
is more practical. The following table is a comparison of the features of
authentication types.
WPA and WPA2
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2
(IEEE 802.11i) is a wireless security standard that defines stronger encryption,
authentication and key management than WPA.
Key differences between WPA or WPA2 and WEP are improved data encryption and
user authentication.
If both an AP and the wireless clients support WPA2 and you have an external
RADIUS server, use WPA2 for stronger data encryption. If you don't have an
external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that
only requires a single (identical) password entered into each access point, wireless
gateway and wireless client. As long as the passwords match, a wireless client will
be granted access to a WLAN.

Appendix D Wireless LANs
P-660HN-Tx User’s Guide 289
If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK
depending on whether you have an external RADIUS server or not.
Select WEP only when the AP and/or wireless clients do not support WPA or WPA2.
WEP is less secure than WPA or WPA2.
Encryption
WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP),
Message Integrity Check (MIC) and IEEE 802.1x. WPA2 also uses TKIP when
required for compatibility reasons, but offers stronger encryption than TKIP with
Advanced Encryption Standard (AES) in the Counter mode with Cipher block
chaining Message authentication code Protocol (CCMP).
TKIP uses 128-bit keys that are dynamically generated and distributed by the
authentication server. AES (Advanced Encryption Standard) is a block cipher that
uses a 256-bit mathematical algorithm called Rijndael. They both include a per-
packet key mixing function, a Message Integrity Check (MIC) named Michael, an
extended initialization vector (IV) with sequencing rules, and a re-keying
mechanism.
WPA and WPA2 regularly change and rotate the encryption keys so that the same
encryption key is never used twice.
The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that
then sets up a key hierarchy and management system, using the PMK to
dynamically generate unique data encryption keys to encrypt every data packet
that is wirelessly communicated between the AP and the wireless clients. This all
happens in the background automatically.
The Message Integrity Check (MIC) is designed to prevent an attacker from
capturing data packets, altering them and resending them. The MIC provides a
strong mathematical function in which the receiver and the transmitter each
compute and then compare the MIC. If they do not match, it is assumed that the
data has been tampered with and the packet is dropped.
By generating unique data encryption keys for every data packet and by creating
an integrity checking mechanism (MIC), with TKIP and AES it is more difficult to
decrypt data on a Wi-Fi network than WEP and difficult for an intruder to break
into the network.
The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The
only difference between the two is that WPA(2)-PSK uses a simple common
password, instead of user-specific credentials. The common-password approach
makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s
still an improvement over WEP as it employs a consistent, single, alphanumeric
password to derive a PMK which is used to generate unique temporal encryption
Appendix D Wireless LANs
P-660HN-Tx User’s Guide
290
keys. This prevent all wireless devices sharing the same encryption keys. (a
weakness of WEP)
User Authentication
WPA and WPA2 apply IEEE 802.1x and Extensible Authentication Protocol (EAP) to
authenticate wireless clients using an external RADIUS database. WPA2 reduces
the number of key exchange messages from six to four (CCMP 4-way handshake)
and shortens the time required to connect to a network. Other WPA2
authentication features that are different from WPA include key caching and pre-
authentication. These two features are optional and may not be supported in all
wireless devices.
Key caching allows a wireless client to store the PMK it derived through a
successful authentication with an AP. The wireless client uses the PMK when it tries
to connect to the same AP and does not need to go with the authentication
process again.
Pre-authentication enables fast roaming by allowing the wireless client (already
connecting to an AP) to perform IEEE 802.1x authentication with another AP
before connecting to it.
Wireless Client WPA Supplicants
A wireless client supplicant is the software that runs on an operating system
instructing the wireless client how to use WPA. At the time of writing, the most
widely available supplicant is the WPA patch for Windows XP, Funk Software's
Odyssey client.
The Windows XP patch is a free download that adds WPA capability to Windows
XP's built-in "Zero Configuration" wireless client. However, you must run Windows
XP to use it.
WPA(2) with RADIUS Application Example
To set up WPA(2), you need the IP address of the RADIUS server, its port number
(default is 1812), and the RADIUS shared secret. A WPA(2) application example
with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is
the distribution system.
1The AP passes the wireless client's authentication request to the RADIUS server.
2The RADIUS server then checks the user's identification against its database and
grants or denies network access accordingly.
3A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by
the RADIUS server and the client.
Appendix D Wireless LANs
P-660HN-Tx User’s Guide 291
4The RADIUS server distributes the PMK to the AP. The AP then sets up a key
hierarchy and management system, using the PMK to dynamically generate
unique data encryption keys. The keys are used to encrypt every data packet that
is wirelessly communicated between the AP and the wireless clients.
Figure 160 WPA(2) with RADIUS Application Example
WPA(2)-PSK Application Example
A WPA(2)-PSK application looks as follows.
1First enter identical passwords into the AP and all wireless clients. The Pre-Shared
Key (PSK) must consist of between 8 and 63 ASCII characters or 64 hexadecimal
characters (including spaces and symbols).
2The AP checks each wireless client's password and allows it to join the network
only if the password matches.
3The AP and wireless clients generate a common PMK (Pairwise Master Key). The
key itself is not sent over the network, but is derived from the PSK and the SSID.
Appendix D Wireless LANs
P-660HN-Tx User’s Guide
292
4The AP and wireless clients use the TKIP or AES encryption process, the PMK and
information exchanged in a handshake to create temporal encryption keys. They
use these keys to encrypt data exchanged between them.

Antenna Overview
An antenna couples RF signals onto air. A transmitter within a wireless device
sends an RF signal to the antenna, which propagates the signal through the air.
The antenna also operates in reverse by capturing RF signals from the air.
Positioning the antennas properly increases the range and coverage area of a
wireless LAN.
Antenna Characteristics
Frequency
An antenna in the frequency of 2.4GHz (IEEE 802.11b and IEEE 802.11g) or 5GHz
(IEEE 802.11a) is needed to communicate efficiently in a wireless LAN
Radiation Pattern
A radiation pattern is a diagram that allows you to visualize the shape of the
antenna’s coverage area.
Antenna Gain
Antenna gain, measured in dB (decibel), is the increase in coverage within the RF
beam width. Higher antenna gain improves the range of the signal for better
communications.
For an indoor site, each 1 dB increase in antenna gain results in a range increase
of approximately 2.5%. For an unobstructed outdoor site, each 1dB increase in
gain results in a range increase of approximately 5%. Actual results may vary
depending on the network environment.
Antenna gain is sometimes specified in dBi, which is how much the antenna
increases the signal power compared to using an isotropic antenna. An isotropic
antenna is a theoretical perfect antenna that sends out radio signals equally well
in all directions. dBi represents the true gain that the antenna provides.
Types of Antennas for WLAN
There are two types of antennas used for wireless LAN applications.
Appendix D Wireless LANs
P-660HN-Tx User’s Guide
294
•Omni-directional antennas send the RF signal out in all directions on a horizontal
plane. The coverage area is torus-shaped (like a donut) which makes these
antennas ideal for a room environment. With a wide coverage area, it is possible
to make circular overlapping coverage areas with multiple access points.
• Directional antennas concentrate the RF signal in a beam, like a flashlight does
with the light from its bulb. The angle of the beam determines the width of the
coverage pattern. Angles typically range from 20 degrees (very directional) to
120 degrees (less directional). Directional antennas are ideal for hallways and
outdoor point-to-point applications.
Positioning Antennas
In general, antennas should be mounted as high as practically possible and free of
obstructions. In point-to–point application, position both antennas at the same
height and in a direct line of sight to each other to attain the best performance.
For omni-directional antennas mounted on a table, desk, and so on, point the
antenna up. For omni-directional antennas mounted on a wall or ceiling, point the
antenna down. For a single AP application, place omni-directional antennas as
close to the center of the coverage area as possible.
For directional antennas, point the antenna in the direction of the desired
coverage area.
P-660HN-Tx User’s Guide 295
APPENDIX E
IPv6
Overview
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 1038 IP addresses.
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.
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.
Appendix E IPv6
P-660HN-Tx User’s Guide
296
Link-local Address
A link-local address uniquely identifies a device on the local network (the LAN). It
is similar to a “private IP address” in IPv4. You can have the same link-local
address on multiple interfaces on a device. A link-local unicast address has a
predefined prefix of fe80::/10. The link-local unicast address format is as follows.
Table 96 Link-local Unicast Address Format
Global Address
A global address uniquely identifies a device on the Internet. It is similar to a
“public IP address” in IPv4. A global unicast address starts with a 2 or 3.
Unspecified Address
An unspecified address (0:0:0:0:0:0:0:0 or ::) is used as the source address
when a device does not have its own address. It is similar to “0.0.0.0” in IPv4.
Loopback Address
A loopback address (0:0:0:0:0:0:0:1 or ::1) allows a host to send packets to
itself. It is similar to “127.0.0.1” in IPv4.
Multicast Address
In IPv6, multicast addresses provide the same functionality as IPv4 broadcast
addresses. Broadcasting is not supported in IPv6. A multicast address allows a
host to send packets to all hosts in a multicast group.
Multicast scope allows you to determine the size of the multicast group. A
multicast address has a predefined prefix of ff00::/8. The following table describes
some of the predefined multicast addresses.
1111 1110 10 0 Interface ID
10 bits 54 bits 64 bits
Table 97 Predefined Multicast Address

FF05:0:0:0:0:0:1:3 All DHCP severs on a local site.
Appendix E IPv6
P-660HN-Tx User’s Guide 297
The following table describes the multicast addresses which are reserved and can
not be assigned to a multicast group.
Subnet Masking
Both an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits,
which are divided into eight 16-bit blocks and written in hexadecimal notation.
Hexadecimal uses four bits for each character (1 ~ 10, A ~ F). Each block’s 16 bits
are then represented by four hexadecimal characters. For example,
FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.
Interface ID
In IPv6, an interface ID is a 64-bit identifier. It identifies a physical interface (for
example, an Ethernet port) or a virtual interface (for example, the management IP
address for a VLAN). One interface should have a unique interface ID.
EUI-64
The EUI-64 (Extended Unique Identifier) defined by the IEEE (Institute of
Electrical and Electronics Engineers) is an interface ID format designed to adapt
with IPv6. It is derived from the 48-bit (6-byte) Ethernet MAC address as shown
next. EUI-64 inserts the hex digits fffe between the third and fourth bytes of the

MAC address and complements the seventh bit of the first byte of the MAC
address. See the following example.
Stateless Autoconfiguration
With stateless autoconfiguration in IPv6, addresses can be uniquely and
automatically generated. Unlike DHCPv6 (Dynamic Host Configuration Protocol
version six) which is used in IPv6 stateful autoconfiguration, the owner and status
of addresses don’t need to be maintained by a DHCP server. Every IPv6 device is
able to generate its own and unique IP address automatically when IPv6 is
initiated on its interface. It combines the prefix and the interface ID (generated
from its own Ethernet MAC address, see Interface ID and EUI-64) to form a
complete IPv6 address.
When IPv6 is enabled on a device, its interface automatically generates a link-local
address (beginning with fe80).
When the interface is connected to a network with a router and the ZyXEL Device
is set to automatically obtain an IPv6 network prefix from the router for the
interface, it generates 3another address which combines its interface ID and
global and subnet information advertised from the router. This is a routable global
IP address.
DHCPv6
The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a
server-client protocol that allows a DHCP server to assign and pass IPv6 network
addresses, prefixes and other configuration information to DHCP clients. DHCPv6
servers and clients exchange DHCP messages using UDP.
Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which
is used for identification when they are exchanging DHCPv6 messages. The DUID
is generated from the MAC address, time, vendor assigned ID and/or the vendor's
private enterprise number registered with the IANA. It should not change over
time even after you reboot the device.
Identity Association
An Identity Association (IA) is a collection of addresses assigned to a DHCP client,
through which the server and client can manage a set of related IP addresses.
MAC 00 : 13 : 49 :12 : 34 :56
EUI-64 02:13 :49 :FF :FE :12 : 34 :56
3. In IPv6, all network interfaces can be associated with several addresses.
Appendix E IPv6
P-660HN-Tx User’s Guide 299
Each IA must be associated with exactly one interface. The DHCP client uses the
IA assigned to an interface to obtain configuration from a DHCP server for that
interface. Each IA consists of a unique IAID and associated IP information.
The IA type is the type of address in the IA. Each IA holds one type of address.
IA_NA means an identity association for non-temporary addresses and IA_TA is an
identity association for temporary addresses. An IA_NA option contains the T1 and
T2 fields, but an IA_TA option does not. The DHCPv6 server uses T1 and T2 to
control the time at which the client contacts with the server to extend the lifetimes
on any addresses in the IA_NA before the lifetimes expire. After T1, the client
sends the server (S1) (from which the addresses in the IA_NA were obtained) a
Renew message. If the time T2 is reached and the server does not respond, the
client sends a Rebind message to any available server (S2). For an IA_TA, the
client may send a Renew or Rebind message at the client's discretion.
DHCP Relay Agent
A DHCP relay agent is on the same network as the DHCP clients and helps forward
messages between the DHCP server and clients. When a client cannot use its link-
local address and a well-known multicast address to locate a DHCP server on its
network, it then needs a DHCP relay agent to send a message to a DHCP server
that is not attached to the same network.
The DHCP relay agent can add the remote identification (remote-ID) option and
the interface-ID option to the Relay-Forward DHCPv6 messages. The remote-ID
option carries a user-defined string, such as the system name. The interface-ID
option provides slot number, port information and the VLAN ID to the DHCPv6
server. The remote-ID option (if any) is stripped from the Relay-Reply messages
before the relay agent sends the packets to the clients. The DHCP server copies
the interface-ID option from the Relay-Forward message into the Relay-Reply
message and sends it to the relay agent. The interface-ID should not change even
after the relay agent restarts.
Prefix Delegation
Prefix delegation enables an IPv6 router to use the IPv6 prefix (network address)
received from the ISP (or a connected uplink router) for its LAN. The ZyXEL Device
uses the received IPv6 prefix (for example, 2001:db2::/48) to generate its LAN IP
address. Through sending Router Advertisements (RAs) regularly by multicast, the

ZyXEL Device passes the IPv6 prefix information to its LAN hosts. The hosts then
can use the prefix to generate their IPv6 addresses.
ICMPv6
Internet Control Message Protocol for IPv6 (ICMPv6 or ICMP for IPv6) is defined in
RFC 4443. ICMPv6 has a preceding Next Header value of 58, which is different
from the value used to identify ICMP for IPv4. ICMPv6 is an integral part of IPv6.
IPv6 nodes use ICMPv6 to report errors encountered in packet processing and
perform other diagnostic functions, such as "ping".
Multicast Listener Discovery
The Multicast Listener Discovery (MLD) protocol (defined in RFC 2710) is derived
from IPv4's Internet Group Management Protocol version 2 (IGMPv2). MLD uses
ICMPv6 message types, rather than IGMP message types. MLDv1 is equivalent to
IGMPv2 and MLDv2 is equivalent to IGMPv3.
MLD allows an IPv6 switch or router to discover the presence of MLD listeners who
wish to receive multicast packets and the IP addresses of multicast groups the
hosts want to join on its network.
MLD snooping and MLD proxy are analogous to IGMP snooping and IGMP proxy in
IPv4.
MLD filtering controls which multicast groups a port can join.
MLD Messages
A multicast router or switch periodically sends general queries to MLD hosts to
update the multicast forwarding table. When an MLD host wants to join a
multicast group, it sends an MLD Report message for that address.
An MLD Done message is equivalent to an IGMP Leave message. When an MLD
host wants to leave a multicast group, it can send a Done message to the router
or switch. The router or switch then sends a group-specific query to the port on
which the Done message is received to determine if other devices connected to
this port should remain in the group.
Example - Enabling IPv6 on Windows XP/2003/Vista
By default, Windows XP and Windows 2003 support IPv6. This example shows you
how to use the ipv6 install command on Windows XP/2003 to enable IPv6. This
Appendix E IPv6
P-660HN-Tx User’s Guide 301
also displays how to use the ipconfig command to see auto-generated IP
addresses.
IPv6 is installed and enabled by default in Windows Vista. Use the ipconfig
command to check your automatic configured IPv6 address as well. You should
see at least one IPv6 address available for the interface on your computer.
Example - Enabling DHCPv6 on Windows XP
Windows XP does not support DHCPv6. If your network uses DHCPv6 for IP
address assignment, you have to additionally install a DHCPv6 client software on
your Windows XP. (Note: If you use static IP addresses or Router Advertisement
for IPv6 address assignment in your network, ignore this section.)
This example uses Dibbler as the DHCPv6 client. To enable DHCPv6 client on your
computer:
1Install Dibbler and select the DHCPv6 client option on your computer.
