1.2.1 Good Habits for Managing the ZyXEL Device
Do the following things regularly to make the ZyXEL Device more secure and to
manage the ZyXEL Device more effectively.
• Change the password. Use a password that’s not easy to guess and that consists
of different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it).
Restoring an earlier working configuration may be useful if the device becomes
unstable or even crashes. If you forget y our password, you will hav e to reset the
ZyXEL Device to its factory default settings . If yo u backed up an earlier
configuration file, you would not have to totally re-configure the ZyXEL Device.
You could simply restore your last configuration.
1.3 Internet Access
Your ZyXEL Device provides shared Internet access by connecting the DSL port to
the DSL or MODEM jack on a splitter or your telephone jack. Computers can
connect to the ZyXEL Device’s LAN port or wirelessly.
Figure 1 Internet Access Example
You can al so configure firewall and filtering feature on the ZyXEL Device for secure
Internet access. When the firewall is on, all incoming traffic from the Internet to
your network is blocked unless it is initiated from your network. This means that
probes from the outside to your network are not allowed, but you can safely
browse the Internet and download files.
22
Use the filtering feaure to block access to specific web sites or Internet
applications such as MSN or Yahoo Messanger. You can also configure IP/MAC
filtering rules for incoming or outgoing traffic.
P-660N-T1A User’s Guide
Use QoS to efficiently manage traffic on your network by giving priority to certain
types of traffic and/or to particular c omput ers. For example, you could make sure
that the ZyXEL Device gives Voice over Internet (VoIP) calls high priority, and/or
limit bandwidth devoted to the boss’s excessive file downloading.
1.4 Wireless Access
The ZyXEL Device is a wireless Access Point (AP) for wireless clients, such as
notebook computers or PDAs and iPads. It allows them to connect to the Internet
without having to rely on inconvenient Ethernet cables.
You can configure your wireless network in either the built -in Web Configurator, or
using the WPS button.
Figure 2 Wireless Access Example
Chapter 1 Introduction
However, befo re you can use this ZyXEL Device to create a wireless network, you
must set its country code first in the Web Configurator. This is very important.
To set the wireless country code:
1 Log into the ZyXEL Device’s built-in Web Configurator. See Chapter 8 on page 99.
2 Open the Network > Wireless LAN > AP screen.
3 Select your country from the Channel Selection list. See Section 8.2 on page
101 for details.
4 Click Apply to save your changes.
5 Finally, open th e Int e rn et and Wireless Configuration wizards to set up your
network. See Chapter 5 on page 53.

4.2 Setting Up a Secure Wireless Network
Thomas wants to set up a wireless network so that he can use his notebook to
access the Internet. In this wireless network, the ZyXEL Device serves as an
access point (AP), and the notebook is the wireless client. The wireless client can
access the Internet through the AP.
Thomas has to configure the wireless network settings on the ZyXEL Device. Then
he can set up a wireless network using WPS (Section 4.2.2 on page 41) or manual
configuration (Section 4.2.3 on page 45).

4.2.2 Using WPS
This section shows you how to set up a wireless network using WPS. It uses the
ZyXEL Device as the AP and ZyXEL NWD210N as the wireless client which
connects to the notebook.
Note: The wireless client must be a WPS-aware device (for example, a WPS USB
adapter or PCMCIA card).
There are two WPS methods to set up the wireless client settings:
• Push Button Configuration (PBC) - simply press a button. This is the easier
of the two methods.
• PIN Configuration - configure a Personal Identification Number (PIN) on the
ZyXEL Device. A wireless client must also use the same PIN in order to
download the wireless network settings from the ZyXEL Device.
Push Button Configuration (PBC)

WAN Setup
6.1 Overview
This chapter describes how to configure WAN settings from the WAN screens. Use
these screens to configure your ZyXEL Device 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 29 LAN and WAN
6.1.1 What You Can Do in the WAN Screens
•Use the Internet Connection screen (Section 6.2 on page 69) to configure the
WAN settings on the ZyXEL Device for Internet access.
•Use the More Connections screen (Section 6.3 on page 74) to set up
additional Internet access connections.
6.1.2 What You Need to Know
The following terms and concepts may help as you 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) or PPPoA,
P-660N-T1A User’s Guide
67
Chapter 6 WAN Setup
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 ZyXEL Device, which makes it
accessible from an outside network. It is used by the ZyXEL Device to
communicate with other devices in other networks. It can be static (fixed) or
dynamically assigned by the ISP each time the ZyXEL Device 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) (and a gateway IP add ress if you use
the Ethernet or ENET ENCAP encapsulation method).
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just one.
IGMP
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a Multicast group - it is not used to carry user data.
There are three versions of IGMP. IGMP version 2 and 3 are improvements over
version 1, but IGMP version 1 is still in wide use.
Finding Out More
See Section 6.4 on page 78 for technical background information on WAN.
6.1.3 Before You Begin
You need to know your Internet access settings such as encapsulation and W AN IP
address. Get this information from your ISP.

6.4 Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
6.4.1 Encapsulation
Be sure to use the encapsulation method required by your ISP. The ZyXEL Device
supports the following methods.
78
P-660N-T1A User’s Guide
6.4.1.1 ENET ENCAP
The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented
with the IP network protocol. IP packets are routed between the Ethernet interface
and the WAN interface and then formatted so that they can be understood in a
bridged environment. For instance, it encapsulates routed Ethernet frames into
bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in
the Gateway IP Address field in the wizard or WAN screen. You can get this
information from your ISP.
6.4.1.2 PPP over Ethernet
The ZyXEL Device 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).
Chapter 6 WAN Setup
One of the benefits of PPPoE is the ability to let you access one of multiple network
services, a function known as dynamic servic e selection. This enables the service
provider to easily create and offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both yo u 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 ZyXEL Device (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of
the LANs’ computers will have access.
6.4.1.3 PPPoA
PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A
PPPoA connection functions like a dial-up Internet connection. The ZyXEL Device
encapsulates the PPP session based on RFC1483 and sends it through an ATM PVC
(Permanent Virtual Circuit) to the Internet Service Provider’s (ISP) DSLAM (Digital
Subscriber Line (DSL) Access Multiplexer). Please refer to RFC 2364 for more
information on PPPoA. Refer to RFC 1661 for more information on PPP.
6.4.1.4 RFC 1483
RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM
Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple
protocols over a single A TM virtual circuit (LL C-based multiplexing) and the second
P-660N-T1A User’s Guide
79
Chapter 6 WAN Setup
method assumes that each protocol is carried over a separate ATM virtual circuit
(VC-based multiplexing). Please refer to RFC 1483 for more detailed information.
6.4.2 Multiplexing
There are two conventions to identify what protocols the virtual circuit (VC) is
carrying. Be sure to use the multiplexing method required by your ISP.
VC-based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific
virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be
dominant in environments where dynamic creation of large numbers of ATM VCs is
fast and economical.
LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information
being contained in each packet header. Despite the extra bandwidth and
processing overhead, this method may be advantageous if it is not practical to
have a separate VC for each carried protocol, for example, if charging heavily
depends on the number of simultaneous VCs.
6.4.3 VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel
Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255
and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM
traffic). Please see the appendix for more information.
6.4.4 IP Address Assignment
A static IP is a fixed IP that your ISP gives y ou. A dynamic IP is not fix e d; the ISP
assigns you a different one each time. The Single User Account feature can be
enabled or disabled if you have either a dynamic or static IP. However the
encapsulation method assigned influences your choices for IP address and ENET
ENCAP gateway.
IP Assignment with PPPoA or PPPoE Encapsulation
If you have a dynamic IP, then the IP Address and Gateway IP Address fields
are not applicable (N/A). If you have a static IP, then you only need to fill in the IP
Address field and not the Gateway IP Address field.
80
P-660N-T1A User’s Guide
IP Assignment with RFC 1483 Encapsulation
In this case the IP address assignment must be static.
IP Assignment with ENET ENCAP Encapsulation
In this case you can have either a static or dynamic IP. For a static IP you must fill
in all the IP Address and Gateway IP Address fields as supplied by your ISP.
However for a dynamic IP, the ZyXEL Device acts as a DHCP client on the WAN
port and so the IP Address and Gateway IP Address fields are not applicable
(N/A) as the DHCP server assigns them to the ZyXEL Device.
6.4.5 Nailed-Up Connection (PPP)
A nailed-up connection is a dial-up line where the connection is always up
regardless of traffic demand. The ZyXEL Device does two things when you speci fy
a nailed-up connection. The first is that idle timeout is dis abled. The second is that
the ZyXEL Device will try to bring up the connection when turne d on and
whenever the connection is down. A nailed-up connection can be very expensive
for obvious reasons.
Chapter 6 WAN Setup
Do not specify a nailed-up connection unless your telephone company offers flatrate service or you need a constant connection and the cost is of no concern.
6.4.6 NAT
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP
address of a host in a packet, for example, the source address of an outgoing
packet, used within one network to a different IP address known within another
network.
6.5 Traffic Shaping
T r affic Shaping is an agreement between the carrier and the subscriber to regulate
the average rate and fluctuations of data transmission over an ATM network. This
agreement helps eliminate congestion, which is important for transmission of real
time data such as audio and video connections.
Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This
parameter may be lower (but not higher) than the maximum line speed. 1 ATM
cell is 53 bytes (424 bits), so a maximum speed of 832Kbps gives a maximum
PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the
line speed.
P-660N-T1A User’s Guide
81
Chapter 6 WAN Setup
Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It
specifies the maximum average rate at which cells can be sent over the virtual
connection. SCR may not be greater than the PCR.
Maximum Burst Size (MBS) is the maximum number of cells that can be sent at
the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to
the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR
again.
If the PCR, SCR or MBS is set to the default of "0", the system will assign a
maximum value that correlates to your upstream line rate.
The following figure illustrates the relationship between PCR, SCR and MBS.
Figure 35 Example of Traffic Shaping
6.5.1 ATM Traffic Classes
These are the basic ATM traffic classes defined by the ATM Forum Traffic
Management 4.0 Specification.
Constant Bit Rate (CBR)
Constant Bit Rate (CBR) provides fixed bandwidth that is always available even if
no data is being sent. CBR traffic is generally time-sensitive (doesn't tolerate
delay). CBR is used for connections that continuously require a specific amount of
bandwidth. A PCR is specified and if traffic exceeds this rate, cells may be
dropped. Examples of connections that need CBR would be high-resolution video
and voice.
Variable Bit Rate (VBR)
The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections.
Connections that use the Variable Bit Rate (VBR) traffic class can be grouped into
real time (VBR-RT) or non-real time (VBR-nRT) connections.
82
P-660N-T1A User’s Guide
Chapter 6 WAN Setup
The VBR-R T (real-time V ariable Bit Rate) type is used with burst y connections that
require closely controlled delay and delay variation. It also provides a fixed
amount of bandwidth (a PCR is specified) but is only available when data is being
sent. An example of an VBR-RT connection would be video conferencing. Video
conferencing requires real-time data transfers and the bandwidth requirement
varies in proportion to the video image's changing dynamics.
The VBR-nRT (non real-time Variable Bit Rate) type is used with bursty
connections that do not require closely controlled delay and delay variation. It is
commonly used for "bursty" traffic typical on LANs. PCR and MBS define the burst
levels, SCR defines the minimum level. An example of an VBR-nRT connection
would be non-time sensitive data file transfers.
Unspecified Bit Rate (UBR)
The Unspecified Bit Rate (UBR) ATM traffic class is for bursty data transfers .
However, UBR doesn't guarantee any bandwidth and only delivers traffic when the
network has spare bandwidth. An example application is background file transfer.

7.1 Overview
A Local Area Network (LAN) is a shared communication system to which many
networking devices are connected. It is usually located in one immediate area
such as a building or floor of a building.
Use the LAN screens to help you configure a LAN DHCP server and manage IP
addresses.
7.1.1 What You Can Do in the LAN Screens
•Use the IP screen (Section 7.2 on page 87) to set the LAN IP address and
subnet mask of your ZyXEL device. You can also edit your ZyXEL Device's RIP,
multicast, and Windows Networking settings from this screen.
•Use the DHCP Setup screen (Section 7.3 on page 89) to configure the ZyXEL
Device’s DHCP settings.
•Use the Client List screen (Section 7.4 on page 90) to assign IP addresses on
the LAN to specific individual computers based on their MAC Addresses.
•Use the IP Alias screen (Section 7.5 on page 91) to change your ZyXEL
Device’s IP alias settings.
P-660N-T1A User’s Guide

Chapter 7 LAN Setup
7.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
IP Address
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 Mask
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.
DHCP
A DHCP (Dynamic Host Configuration Protocol) server can assign your ZyXEL
Device an IP address, subnet mask, DNS and other routing information when it's
turned on.
RIP
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers.
Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just 1.
IGMP
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a Multicast group - it is not used to carry user data.
There are three versions of IGMP. IGMP version 2 and 3 are improvements over
version 1, but IGMP version 1 is still in wide use.
86
DNS
DNS (Domain Name System) is for mapping a domain name to its corresponding
IP address and vice versa. The DNS server is extremely important because
P-660N-T1A User’s Guide
without it, you must know the IP address of a networking device before you can
access it.

LABEL DESCRIPTION
RIP Direction RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a
router to exchange routing information with other routers. The RIP
Direction field controls the sending and receiving of RIP packets.
Select the RIP direction from Both/In Only/Out Only/None. When
set to Both or Out Only, the ZyXEL Device will broadcast its routing
table periodically. When set to Both or In Only, it will incorporate the
RIP information that it receives; when set to None, it will not send any
RIP packets and will ignore any RIP packets received.
RIP Version The RIP Version field controls the format and the broadcasting
method of the RIP packets that the ZyXEL Device sends (it recognizes
both formats when receiving). RIP-1 is universally supported but RIP-2
carries more information. RIP-1 is probably adequate for most
networks, unless you have an unusual network topology. Both RIP-2B
and RIP-2M sends the routing data in RIP-2 format; the difference
being that RIP-2B uses subnet broadcasting while RIP-2M uses
multicasting. Multicasting can reduce the load on non-router machines
since they generally do not listen to the RIP multicast address and so
will not receive the RIP packets. However, if one router uses
multicasting, then all routers on your network must use multicasting,
also. By default, RIP direction is set to Both and the Version set to
RIP-1.

7.6 Technical Reference
This section provides some technical background information about the topics
covered in this chapter.
7.6.1 LANs, WANs and the ZyXEL Device
The actual physical connection determines whether the ZyXEL Device ports are
LAN or WAN ports. There are two separate IP networks, one inside the LAN
network and the other outside the WAN network as shown next.
Figure 42 LAN and WAN IP Addresses
7.6.2 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients to obtain TCP/IP configuration at start-up from a server. Y ou can
configure the ZyXEL Device as a DHCP server or disable it. When configured as a
server, the ZyXEL Device provides the TCP/IP configuration for the clients. If you
turn DHCP service off, you must have another DHCP server on your LAN, or else
the computer must be manually configured.
IP Pool Setup
The ZyXEL Device is pre-configured with a pool of IP addresses for the DHCP
clients (DHCP Pool). See the product specif ic a t i o ns in the appendices. Do not
assign static IP addresses from the DHCP pool to your LAN computers.
7.6.3 DNS Server Addresses
DNS (Domain Name System) maps a domain name to its corresponding IP
address and vice versa. The DNS server is extremely important because without
it, you must know the IP address of a computer before you can access it. The DNS
94
P-660N-T1A User’s Guide
server addresses you enter when you set up DHCP are passed to the client
machines along with the assigned IP address and subnet mask.
There are two ways that an ISP disseminates the DNS server addresses.
• The ISP tells you the DNS server addresses, usually in the form of an
information sheet, when you sign up. If your I SP gives you DNS se rver
addresses, enter them in the DNS Server fields in the DHCP Setup screen.
• Some ISPs choose to disseminate the DNS server addresses using the DNS
server extensions of IPCP (IP Control Protocol) after the connection is up. If
your ISP did not give you explicit DNS servers, chances are the DNS servers are
conveyed through IPCP negotiation. The ZyXEL Device supports the IPCP DNS
server extensions through the DNS proxy feature.
Please note that DNS proxy works only when the ISP uses the IPCP DNS serve r
extensions. It does not mean you can leave the DNS servers out of the DHCP
setup under all circumstances. If your ISP gives you explicit DNS servers, make
sure that you enter their IP addresses in the DHCP Setup screen.
7.6.4 LAN TCP/IP
Chapter 7 LAN Setup
The ZyXEL Device has built-in DHCP server capability that assigns IP addresses
and DNS servers to systems that support DHCP client capability.
IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, so too do
computers on a LAN share one common network number.
Where you obtain your network number depends on your particular situation. If
the ISP or your network administrator assigns you a block of registered IP
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 and you must enable the
Network Address Translation (NAT) feature of the ZyXEL Device. The Internet
Assigned Number Authority (IANA) reserved this block of addresses sp ecifically for
private use; please do not use any other number unless you are told otherwise.
Let's say you select 192.168.1.0 as the network number; which covers 254
individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are
reserved). In other words, the first three numbers specify the network number
while the last number identifies an individual computer on that network.
P-660N-T1A User’s Guide
95
Chapter 7 LAN Setup
Once you have decided on the network number , pick an IP address that is easy to
remember, for instance, 192.168.1.1, for your ZyXEL Device, 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. Y ou 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, for example, only between your two branch offices, you
can assign IP addresses to the hosts without problems. However, the Internet
Assigned Numbers Authority (IANA) has reserve d 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.
Note: 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”.
7.6.5 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers. The RIP Direction field controls the sending and
receiving of RIP packets. When set to:
• Both - the ZyXEL Device will broadcast its routing table periodically and
incorporate the RIP information that it receives.
96
• In Only - the ZyXEL Device will not send any RIP packets but will accept all RIP
packets received.
• Out Only - the ZyXEL Device will send out RIP packets but will not accept any
RIP packets received.
P-660N-T1A User’s Guide
• None - the ZyXEL Device will not send any RIP packets and will ignore any RIP
packets received.
The Version field controls the format and the broadcasting method of the RIP
packets that the ZyXEL Device sends (i t recognizes bot h formats when receiving).
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is
probably adequate for most networks, unless you have an unusual network
topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference
being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.
7.6.6 Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just 1.
Chapter 7 LAN Setup
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a Multicast group - it is not used to carry user data. IGMP
version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP
version 1 is still in wide use. IGMP version 3 supports source filtering, reporting or
ignoring traffic from specific source address to a particular host on the network. If
you would like to read more detail e d information about interoperability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class
D IP address is used to identify host groups and can be in the range 224.0.0.0 to
239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used
by IP multicast computers. The address 224.0.0.1 is used for query messages and
is assigned to the permanent group of all IP hosts (including gateways). All hosts
must join the 224.0.0.1 group in order to participate in IGMP. The address
224.0.0.2 is assigned to the multicast routers group.
The ZyXEL Device supports IGMP version 1 (IGMP-v1), IGMP version 2 (IGMP-
v2) and IGMP version 3 (IGMP-v3). At start up, the ZyXEL Device queries all
directly connected networks to gather group membership. After that, the ZyXEL
Device periodically updates this information. IP multicasting can be enabled/
disabled on the ZyXEL Device LAN and/or WAN interfaces in the web configurator
(LAN; WAN). Select None to disable IP multicasting on these interfaces.

Chapter 8 Wireless LAN
You don’t necessarily need to use all these screens to set up your wireless
connection. For example, you may just want to set up a network name, a wireless
radio channel and security in the AP screen.
8.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie
radios send and receive information over the airwaves, wireless networking
devices exchange information with one another. A wireless networking device is
just like a radio that lets your computer exchange information with radios
attached to other computers. Like walkie-talkies, most wireless networking
devices operate at radio frequency bands that are open to the public and do not
require a license to use. However, wireless networking is different from that of
most traditional radio communications in that there a number of wireless
networking standards available with different methods of data encryption.
SSID
Each network must have a name, referred to as the SSID - “Ser vice Set
IDentifier”. The “service set” is the network, so the “service set ident i fier” is the
network’s name. This helps you identify your wireless network when wireless
networks’ coverage areas overlap and you have a variety of networks to choose
from.
MAC Address Filter
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address consists of twelve hexadecimal characters (0-9, and A to F), and it is
usually written in the following form at: “0A:A0:00:BB:CC:DD”.
The MAC address filter controls access to the wireless network. You can use the
MAC address of each wireless client to allow or deny access to the wireless
network.
