Getting to Know Your ZyXEL

This chapter introduces the main features and applications of the ZyXEL Device.

1.1 Overview

The ZyXEL Device is a wireless secure router with a 4-port switch and 56K modem.

The ZyXEL Device is always used as a wireless broadband router with a WAN dial-up
connection. You can also deploy the ZyXEL Device as an access point (AP) or a WiFi WAN
router. When you use the ZyXEL Device as a WiFi WAN router, you access the Internet via a
wireless WAN connection and still take advantage of a host of features such as NAT, firewall,
content filtering and bandwidth management.

P-334WHD User’s Guide

CHAPTER 1

Device

See Appendix A on page 217 for a complete list of features.

1.2 Applications for the ZyXEL Device

Here are some examples of what you can do with your ZyXEL Device.

The ZyXEL Device supports three operating modes: Router, Access Point and WiFi WAN
Router.

1.2.1 Router Mode

The ZyXEL Device is in Router mode by default and functions as a normal (wireless) router.

1.2.1.1 Internet Access via a Broadband Connection

For Internet access, connect the WAN Ethernet port to your existing Internet access gateway
(company network, or your cable or DSL modem for example). Connect computers or servers
to the LAN ports for shared Internet access.

Wireless clients can move freely anywhere in the coverage area and use resources on the wired
network.

See the Quick Start Guide for instructions on hardware connections.

Chapter 1 Getting to Know Your ZyXEL Device 29

P-334WHD User’s Guide

Figure 1 Router Mode: Internet Access via a Broadband Connection

You can also configure firewall and content filtering 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 for
example.

Use content filtering to block access to web sites containing keywords that you specify. You
can define time periods and days during which content filtering is enabled and include or
exclude particular computers on your network from content filtering. For example, you could
block access to certain web sites for the kids.

Use bandwidth management to efficiently manage traffic on your network by giving priority
to certain types of traffic and/or to particular computers. For example, you could make sure
that voice over Internet calls get enough bandwidth in your network, and/or limit bandwidth
devoted to the boss’s excessive file downloading.

1.2.1.2 Internet Access via a Dial-up Connection

Alternatively, the computers connected to the ZyXEL Device can share Internet access via the
built-in 56K modem. If both the broadband and dial-up WAN connections are set up, the
ZyXEL Device uses the dial-up connection (via the modem) as a backup. When the primary
broadband WAN connection is down, the ZyXEL Device changes to use the dial-up WAN
connection automatically.

Figure 2 Router Mode: Internet Access via a Dial-up Connection

30 Chapter 1 Getting to Know Your ZyXEL Device

1.2.2 Access Point Mode

You can have the ZyXEL Device works as a pure access point (AP). It allows you to
transparently install the ZyXEL Device in your network and there is no change needed to your
current network. When the ZyXEL Device is in Access Point mode, all LAN and WAN ports
act as a hub.

The application diagram for Access Point mode is similar to Router mode, except that the
ZyXEL Device in Access Point mode does not have advanced features, such as NAT, DHCP
server, firewall, bandwidth management, etc.

Figure 3 ZyXEL Device as an AP

P-334WHD User’s Guide

1.2.3 WiFi WAN Router Mode

If you set the ZyXEL Device to WiFi WAN Router mode, the ZyXEL Device uses a wireless
WAN connection via an AP or wireless router, instead of a wired connection via a DSL/cable
modem.

Note: You can set the ZyXEL Device to WiFi WAN router mode only when you use

Ethernet encapsulation.

When the ZyXEL Device is in WiFi WAN Router mode, all LAN and WAN ports act as a
hub. You cannot connect them to a modem or router. In this mode, the ZyXEL Device does
not allow network access to wireless clients (WLAN).

Introducing the Web

This chapter describes how to access the ZyXEL Device web configurator and provides an
overview of its screens.

2.1 Web Configurator Overview

The web configurator is an HTML-based management interface that allows easy ZyXEL
Device setup and management via Internet browser. Use Internet Explorer 6.0 and later or
Netscape Navigator 7.0 and later versions. The recommended screen resolution is 1024 by 768
pixels.

P-334WHD User’s Guide

CHAPTER 2

Configurator

In order to use the web configurator you need to allow:

• Web browser pop-up windows from your device. Web pop-up blocking is enabled by
default in Windows XP SP (Service Pack) 2.

• JavaScripts (enabled by default).

• Java permissions (enabled by default).

Refer to the Troubleshooting chapter to see how to make sure these functions are allowed in
Internet Explorer.

2.2 Accessing the Web Configurator

1 Make sure your ZyXEL Device hardware is properly connected and prepare your

computer/computer network to connect to the ZyXEL Device (refer to the Quick Start
Guide).

2 Launch your web browser.

3 Type "192.168.1.1" as the URL.

4 Type "1234" (default) as the password and click Login. In some versions, the default

password appears automatically - if this is the case, click Login.

5 You should see a screen asking you to change your password (highly recommended) as

shown next. Type a new password (and retype it to confirm) and click Apply or click
Ignore.

Figure 7 Change Password Screen

Note: The management session automatically times out when the time period set in

the Administrator Inactivity Timer field expires (default five minutes). Simply
log back into the ZyXEL Device if this happens to you.

2.3 Resetting the ZyXEL Device

If you forget your password or cannot access the web configurator, you will need to use the
RESET button at the back of the ZyXEL Device to reload the factory-default configuration
file. This means that you will lose all configurations that you had previously and the password
will be reset to “1234”.

2.3.1 Procedure to Use the Reset Button

1 Make sure the PWR LED is on (not blinking).

2 Press the RESET button for ten seconds or until the PWR LED begins to blink and then

release it. When the PWR LED begins to blink, the defaults have been restored and the
ZyXEL Device restarts.

3.4.2 PPPoE Connection

Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an
IETF (Internet Engineering Task Force) standard specifying how a host personal computer
interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access
to high-speed data networks.

For the service provider, PPPoE offers an access and authentication method that works with
existing access control systems (for instance, RADIUS).

One of the benefits of PPPoE is the ability to let end users access one of multiple network
services, a function known as dynamic service selection. This enables the service provider to
easily create and offer new IP services for specific users.

Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber’s 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 LAN's computers will have
Internet access.

3.4.6 DNS Server Address

Use DNS (Domain Name System) to map a domain name to its corresponding IP address and
vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is
extremely important because without it, you must know the IP address of a computer before
you can access it.

The ZyXEL Device can get the DNS server addresses in the following ways.

1 The ISP tells you the DNS server addresses, usually in the form of an information sheet,

when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS
Server fields in the Wizard and/or WAN > Internet Connection screen.

2 If the ISP did not give you DNS server information, leave the DNS Server fields set to

0.0.0.0 in the Wizard screen and/or set to From ISP in the WA N > Internet Connection

screen for the ISP to dynamically assign the DNS server IP addresses.

70 Chapter 3 Connection Wizard

This chapter discusses how to configure the wireless network settings in your ZyXEL Device.
See the appendices for more detailed information about wireless networks.

4.1 Wireless Network Overview

The following figure provides an example of a wireless network.

Figure 36 Example of a Wireless Network

P-334WHD User’s Guide

CHAPTER 4

Wireless LAN

The wireless network is the part in the blue circle. In this wireless network, devices A and B
are called wireless clients. The wireless clients use the access point (AP) to interact with other
devices (such as the printer) or with the Internet. Your ZyXEL Device is the AP.

Every wireless network must follow these basic guidelines.

• Every wireless client in the same wireless network must use the same SSID.

The SSID is the name of the wireless network. It stands for Service Set IDentity.

• If two wireless networks overlap, they should use different channels.

Like radio stations or television channels, each wireless network uses a specific channel,
or frequency, to send and receive information.

Chapter 4 Wireless LAN 71

P-334WHD User’s Guide

• Every wireless client in the same wireless network must use security compatible with the
AP.

Security stops unauthorized devices from using the wireless network. It can also protect
the information that is sent in the wireless network.

4.2 Wireless Security Overview

The following sections introduce different types of wireless security you can set up in the
wireless network.

4.2.1 SSID

Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can
hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you
should change the default SSID to something that is difficult to guess.

This type of security is fairly weak, however, because there are ways for unauthorized devices
to get the SSID. In addition, unauthorized devices can still see the information that is sent in
the wireless network.

4.2.2 MAC Address Filter

Every wireless client has a unique identification number, called a MAC address.1 A MAC
address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002
or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate
User’s Guide or other documentation.

You can use the MAC address filter to tell the AP which wireless clients are allowed or not
allowed to use the wireless network. If a wireless client is allowed to use the wireless network,
it still has to have the correct settings (SSID, channel, and security). If a wireless client is not
allowed to use the wireless network, it does not matter if it has the correct settings.

This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized
wireless client. Then, they can use that MAC address to use the wireless network.

4.2.3 User Authentication

You can make every user log in to the wireless network before they can use it. This is called
user authentication. However, every wireless client in the wireless network has to support
IEEE 802.1x to do this.

1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless
networks. These kinds of wireless devices might not have MAC addresses.

2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

72 Chapter 4 Wireless LAN

For wireless networks, there are two typical places to store the user names and passwords for
each user.

• In the AP: this feature is called a local user database or a local database.

• In a RADIUS server: this is a server used in businesses more than in homes.

If your AP does not provide a local user database and if you do not have a RADIUS server,
you cannot set up user names and passwords for your users.

Unauthorized devices can still see the information that is sent in the wireless network, even if
they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless
users to get a valid user name and password. Then, they can use that user name and password
to use the wireless network.

Local user databases also have an additional limitation that is explained in the next section.

4.2.4 Encryption

Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.

P-334WHD User’s Guide

The types of encryption you can choose depend on the type of user authentication. (See

Section 4.2.3 on page 72 for information about this.)

Table 29 Types of Encryption for Each Type of Authentication

No Authentication RADIUS Server

Weakest No Security

Static WEP

WPA-PSK

Strongest WPA2-PSK WPA2

WPA

For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2.
If users do not log in to the wireless network, you can choose no encryption, Static WEP,
WPA-PSK, or WPA2-PSK.

Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. For example, suppose the AP does not have a local user database, and you
do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless
network has two wireless clients. Device A only supports WEP, and device B supports WEP
and WPA. Therefore, you should set up Static WEP in the wireless network.

Chapter 4 Wireless LAN 73

P-334WHD User’s Guide

Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger

encryption. IEEE 802.1x and WEP encryption are better than none at all, but it
is still possible for unauthorized devices to figure out the original information
pretty quickly.

It is not possible to use WPA-PSK, WPA or stronger encryption with a local
user database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.

When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option
(WPA Compatible) to support WPA as well. In this case, if some wireless clients support
WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the
type of wireless network login) and select the WPA Compatible option in the ZyXEL Device.

Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every wireless client in the wireless network must
have the same key.

4.3 General Wireless LAN Screen

Note: If you are configuring the ZyXEL Device from a computer connected to the

This section describes how to connect the wireless client to a network.

Chapter 5 Wireless Tutorial 87

P-334WHD User’s Guide

5.3.1 Connecting to a Wireless LAN

The following sections show you how to join a wireless network using the ZyXEL utility, as in
the following diagram. The wireless client is labeled C and the access point is labeled AP.

There are three ways to connect the client to an access point.

• Configure nothing and leave the wireless client to automatically scan for and connect to
any available network that has no wireless security configured.

• Manually connect to a network.

• Configure a profile to have the wireless client automatically connect to a specific network
or peer computer.

This example illustrates how to manually connect your wireless client to an access point (AP)
which is configured for WPA-PSK security and connected to the Internet. Before you connect
to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared
key. In this example, the SSID is “SSID_Example3” and the pre-shared key is
“ThisismyWPA-PSKpre-sharedkey”.

After you install the ZyXEL utility and then insert the wireless client, follow the steps below
to connect to a network using the Site Survey screen.

1 Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.

2 The wireless client automatically searches for available wireless networks. Click Scan if

you want to search again. If no entry displays in the Available Network List, that means
there is no wireless network available within range. Make sure the AP or peer computer is
turned on or move the wireless client closer to the AP or peer computer.

5.3.2 Creating and Using a Profile

A profile lets you automatically connect to the same wireless network every time you use the
wireless client. You can also configure different profiles for different networks, for example if
you connect a notebook computer to wireless networks at home and at work.

This example illustrates how to set up a profile and connect the wireless client to an access
point configured for WPA-PSK security. In this example, the SSID is “SSID_Example3”, the
profile name is “PN_Example3” and the pre-shared key is “ThisismyWPA-PSKpre­sharedkey”. You have chosen the profile name “PN_Example3”.

This chapter describes how to configure WAN settings.

6.1 WAN Overview

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

6.1.1 WAN IP Address Assignment

Every computer on the Internet must have a unique IP address. If your networks are isolated
from the Internet, for instance, only between your two branch offices, 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.

P-334WHD User’s Guide

CHAPTER 6

WAN

Table 37 Private IP Address Ranges

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 have it assigned by 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.

6.1.2 DNS Server Address Assignment

Use DNS (Domain Name System) to map a domain name to its corresponding IP address and
vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is
extremely important because without it, you must know the IP address of a computer before
you can access it.

The ZyXEL Device can get the DNS server addresses in the following ways.

Chapter 6 WAN 95

P-334WHD User’s Guide

1 The ISP tells you the DNS server addresses, usually in the form of an information sheet,

when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS
Server fields in the Wizard and/or WAN > Internet Connection screen.

2 If the ISP did not give you DNS server information, leave the DNS Server fields set to

0.0.0.0 in the Wizard screen and/or set to From ISP in the WA N > Internet Connection

screen for the ISP to dynamically assign the DNS server IP addresses.

6.1.3 WAN MAC Address

The MAC address screen allows users to configure the WAN port's MAC address by either
using the factory default or cloning the MAC address from a computer on your LAN. Choose
Factory Default to select the factory assigned default MAC Address.

Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address
of the computer on the LAN whose MAC you are cloning. Once it is successfully configured,
the address will be copied to the rom file (ZyNOS configuration file). It will not change unless
you change the setting or upload a different ROM file.

It is recommended that you clone the

6.1.4 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 (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. If
you would like to read more detailed 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 both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-
v2). 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.

6.2.2 PPPoE Encapsulation

The ZyXEL Device supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an
IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a
broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet 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).

One of the benefits of PPPoE is the ability to let you access one of multiple network services,
a function known as dynamic service selection. This enables the service provider to easily
create and offer new IP services for individuals.

Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires
no specific configuration of the broadband modem at the customer site.

By implementing PPPoE directly on the 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.

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 (i.e. xDSL, cable, wireless, etc.) connection.
Operationally, PPPoE saves significant effort for both the end user and ISP/carrier,
as it requires no specific configuration of the broadband modem at the customer
site. By implementing PPPoE directly on the router rather than individual
computers, the computers on the LAN do not need PPPoE software installed, since
the router does that part of the task. Further, with NAT, all of the LAN's computers
