CHAPTER
Getting Started
This chapter introduces the main features and applications of the ZyXEL Device.
1.1 About Your ZyXEL Device
The ZyXEL Device is a WiMAX WiFi router with built-in switch and VoIP. It allows you to
access the Internet by connecting to a WiMAX wireless network.
You can create a WiFi network using the Wireless LAN feature.
You can use a traditional analog telephone to make Internet calls using the ZyXEL Device’s
Voice over IP (VoIP) communication capabilities.
You can configure firewall and content filtering for secure Internet access, as well as a host of
other features.
The web browser-based Graphical User Interface (GUI), also known as the web configurator,
provides easy management.
See Chapter 25 on page 269 for a complete list of features for your model.
At the time of writing, this User’s Guide covers the following models:
Table 2 Models Covered
MAX-200HW2
2.5Ghz
MAX-210HW2
3.5Ghz
MAX-230HW2
2.3Ghz
This User’s Guide uses screens and example settings from the MAX-210HW2 model.
1.1.1 Wireless Internet Access
Connect your computer or network to the ZyXEL Device for wireless Internet access. See the
Quick Start Guide for instructions on hardware connection.
In a wireless metropolitan area network (MAN), the ZyXEL Device connects to a base station
(BS) for Internet access.
The following diagram shows a notebook computer equipped with the ZyXEL Device
connecting to the Internet through a base station (marked BS).
MAX-200HW2 Series User’s Guide
33
Chapter 1 Getting Started
Figure 1 Mobile Station and Base Station
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.
Use content filtering to block access to web sites with URLs 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.
1.1.2 WiFi Network
The ZyXEL Device Wireless LAN feature allows IEEE 802.11b or IEEE 802.11g compatible
wireless clients to access the Internet or the local network as well as to communicate with each
other. Wireless stations can move freely anywhere in the coverage area and use resources on
the wired network.
Figure 2 WLAN Application Example
1.1.3 Make Calls via Internet Telephony Service Provider
In a home or small office environment, you can use the ZyXEL Device to make and receive
the following types of VoIP telephone calls:
• Peer-to-Peer calls (A) - Use the ZyXEL Device to make a call to the recipient’s IP address
without using a SIP proxy server.
34
MAX-200HW2 Series User’s Guide
Chapter 1 Getting Started
• Calls via a VoIP service provider (B) - The ZyXEL Device sends your call to a VoIP
service provider’s SIP server which forwards your calls to either VoIP or PSTN phones.

1.2.2 Antennas
If you have a MAX-210HW2 you should have a 2dBi WiFi omni antenna and a 2dBi WiMAX
omni antenna. Connect the WiFi antenna to the SMA connector port labelled WiFi. Connect
the WiMAX antenna to the SMA connector port labelled WiMAX. Make sure you connect the
correct antenna to the correct connector port.
36
MAX-200HW2 Series User’s Guide
Chapter 1 Getting Started
If you have a MAX-200HW2 or MAX-210HW2 you should have a 2dBi Wifi omni antenna
and a panel directional antenna. Connect the WiFi omni antenna to the connector port labelled
WiFi. Connect the cable to the panel directional antenna and connector port labelled WiMAX.
Make sure you position the panel directional antenna as far away from the device as possible
to minimize interference. See the panel directional antenna documentation on how to set it up.
The MAX-210HW2 is also equipped with one internal 6dBi directional patch antenna for
WiMAX. If your signal strength is poor (use the SIGNAL LEDs to gauge received signal
strength) orient the front of the ZyXEL Device (the side with the LEDs) towards the base
station. If you do not know the location of the base station, experiment with moving the
ZyXEL Device while observing the SIGNAL LEDs.
1.3 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 ZyXEL Device becomes unstable or
even crashes. If you forget your password, you will have to reset the ZyXEL Device to its
factory default settings. If you backed up an earlier configuration file, you would not have
to totally re-configure the ZyXEL Device. You could simply restore your last
configuration.

8 Click Apply. Your Internet access settings are saved to the ZyXEL Device, and are used
automatically each time you connect to the Internet.
3.1.2 Configure WiMAX Settings
The WiMAX Frequency screen allows you to specify a set of frequencies to search for a
connection to a base station. Before you start, you need information from your ISP about the
supported frequencies.
In this example, your ISP has told you that the supported WiMAX frequencies are at 2.55 and
2.56 Gigahertz (GHz). See Section 8.4 on page 111 for more information on radio frequencies.
Follow the steps below to configure your frequency settings.
1 Click Network > WAN > WiMAX Frequency to open the screen shown next.
Figure 15 Tutorial: WiMAX Frequency Setup
2 Enter the frequency settings your ISP gave you in the DL Frequency fields. Note that
these fields are in kilohertz (kHz).
2.55 GHz is equal to 2550000 kHz, so enter 2550000 in the DL Frequency [1] field.
2.56 GHz is equal to 2560000 kHZ, so enter 2560000 in the DL Frequency [2] field.
3 Click Apply to save your settings. The ZyXEL Device scans for an available wireless
connection at the DL Frequency [1] setting (2.55 GHz) and, if it does not find an
available connection, searches at the DL Frequency [2] setting (2.56 GHz). When it
finds an available connection, the fields in this screen will be automatically set to use
that frequency.
For an example of using the WiMAX Frequency screen to configure more frequencies,
see Section 8.4.2.1 on page 113.
4 Look at the LEDs on your ZyXEL Device. When the ZyXEL Device successfully
connects to a base station, the LINK LED shines green steadily. The SIGNAL 1 ~ 5
LEDs indicate the signal strength, with SIGNAL 5 showing a very strong signal and
SIGNAL 1 showing a very weak signal.

3.3.1 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 labelled C and the access point is labelled 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.
3 When you try to connect to an AP with security configured, a window will pop up
prompting you to specify the security settings. Enter the pre-shared key and leave the
encryption type at the default setting.
Use the Next button to move on to the next screen. You can use the Back button at any
time to return to the previous screen, or the Exit button to return to the Site Survey
screen.

network using your settings. When the wireless link is established, the ZyXEL utility
icon in the system tray turns green and the Link Info screen displays details of the active
connection. Check the network information in the Link Info screen to verify that you
have successfully connected to the selected network. If the wireless client is not
connected to a network, the fields in this screen remain blank.

3.4 Make a Telephone Call Over the Internet
To make a call over the Internet using the ZyXEL Device, first do the following things:
• Set up hardware connections from the ZyXEL Device to your computer, your telephone
and the power supply (see the Quick Start Guide for more details on hardware
connections).
• Set up your Internet access and WiMAX settings on the ZyXEL Device (see Section 3.1.1
on page 49 and Section 3.1.2 on page 52 for examples).
• Set up an account with a Voice over IP (VoIP) provider. This account (called a SIP
account) allows you to make calls over the Internet. See Chapter 12 on page 149 for more
information on SIP accounts.
Use the sections below to set up your SIP account and speed dialing, and place a VoIP call.
3.4.1 Configure Your SIP Account
Your ZyXEL Device needs to be configured with the details of your SIP account before you
can use it to make calls over the Internet. In this example, your SIP identity is
“id123@abcvoip.com”, your user name is “id123” and your password is “zyx987”. Your VoIP
provider has told you that the SIP server address is “sipserver-abcvoip.com”. See Section
12.1.3 on page 149 for more information on SIP identities.
Once you have connected the ZyXEL Device to your computer and accessed the Web
Configurator (see the Quick Start Guide for details) follow the steps below to configure your
SIP settings.
1 In the Web Configurator, click VoIP > SIP in the navigation panel.
The following screen displays. This screen is where you enter your SIP account details.

is selected.
3 Enter your SIP user name (‘id123’) in the Number field.
4 Enter your VoIP provider’s SIP server name (‘sipserver-abcvoip.com’) in the SIP Server
Address field. As your VoIP provider did not give you a different REGISTER Server
Address, enter ‘sipserver-abcvoip.com’ again.
Enter your VoIP provider’s domain name (‘abcvoip.com’) in the SIP Service Domain
field.
5 In the Authentication area, enter ‘id123’ in the User Name field, and ‘zyx987’ in the
Password field. Leave the SIP Local Port, SIP Server Port and REGISTER Server
Port fields at their default values, as your VoIP provider did not supply port details.
Click Apply.
6 Click on the Status button in the navigation panel to check that your SIP account is
correctly registered.
Look in the VoIP Status area towards the bottom of the Status screen. If the SIP 1
account displays Registered in the Registration field, it is ready to use.
If the Registration field for the SIP 1 account displays Register Fail or Inactive, click
the Register button, check your settings in the VoIP > SIP screen or contact your VoIP
provider to confirm that you have the correct settings and that your account is active.
3.4.2 Configure a Phone
Once you have set up your SIP account, click VoIP > Phone > Analog Phone in the
navigation panel. The following screen displays.

CHAPTER
Wireless LAN
This chapter discusses how to configure the wireless network settings in your ZyXEL Device.
See the appendices for more detailed information about wireless networks.
7.1 Wireless Network Overview
The following figure provides an example of a wireless network.
Figure 50 Example of a Wireless Network
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.
MAX-200HW2 User’s Guide
91
Chapter 7 Wireless LAN
• 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.
7.2 Wireless Security Overview
The following sections introduce different types of wireless security you can set up in the
wireless network.
7.2.1 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.
7.2.2 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.
7.2.3 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.
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.
92
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.
MAX-200HW2 User’s Guide
Chapter 7 Wireless LAN
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.
7.2.4 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.
The types of encryption you can choose depend on the type of user authentication. (See
Section 7.2.3 on page 92 for information about this.)
Table 23 Types of Encryption for Each Type of Authentication
Weakest
NO AUTHENTICATION
RADIUS SERVER
No Security
WPA
Static WEP
WPA-PSK
Strongest
WPA2-PSK
WPA2
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, WPAPSK, 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.
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.
MAX-200HW2 User’s Guide
93
Chapter 7 Wireless LAN
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.
7.2.5 One-Touch Intelligent Security Technology (OTIST)
With ZyXEL’s OTIST, you set up the SSID and WPA-PSK on the ZyXEL Device. Then, the
ZyXEL Device transfers them to the devices in the wireless networks. As a result, you do not
have to set up the SSID and encryption on every device in the wireless network.
The devices in the wireless network have to support OTIST, and they have to be in range of the
ZyXEL Device when you activate it. See Section 7.4 on page 101 for more details.
7.3 General Wireless LAN Screen
If you are configuring the ZyXEL Device from a computer connected to the
wireless LAN and you change the ZyXEL Device’s SSID, channel or security
settings, you will lose your wireless connection when you press Apply to
confirm. You must then change the wireless settings of your computer to
match the ZyXEL Device’s new settings.

7.4 OTIST
In a wireless network, the wireless clients must have the same SSID and security settings as
the access point (AP) or wireless router (we will refer to both as “AP” here) in order to
associate with it. Traditionally this meant that you had to configure the settings on the AP and
then manually configure the exact same settings on each wireless client.
OTIST (One-Touch Intelligent Security Technology) allows you to transfer your AP’s SSID
and WPA-PSK security settings to wireless clients that support OTIST and are within
transmission range. You can also choose to have OTIST generate a WPA-PSK key for you if
you didn’t configure one manually.
OTIST replaces the pre-configured wireless settings on the wireless clients.
7.4.1 Enabling OTIST
You must enable OTIST on both the AP and wireless client before you start transferring
settings.
The AP and wireless client(s) MUST use the same Setup key.
Click the Network > Wireless LAN > OTIST. The following screen displays.

CHAPTER
WAN Setup
This chapter describes how to configure WAN settings.
8.1 WAN Overview
A WAN (Wide Area Network) is an outside connection to another network or the Internet.
Your ZyXEL Device uses the IEEE 802.16e WiMAX standard to connect wirelessly to a
WiMAX base station (see Section 1.1 on page 33).
8.2 WiMAX
WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 wireless
networking standard, which provides high-bandwidth, wide-range wireless service across
wireless Metropolitan Area Networks (MANs). ZyXEL is a member of the WiMAX Forum,
the industry group dedicated to promoting and certifying interoperability of wireless
broadband products.
In a wireless MAN, a wireless-equipped computer is known either as a mobile station (MS) or
a subscriber station (SS). Mobile stations use the IEEE 802.16e standard and are able to
maintain connectivity while switching their connection from one base station to another base
station (handover) while subscriber stations use other standards that do not have this capability
(IEEE 802.16-2004, for example). The following figure shows an MS-equipped notebook
computer MS1 moving from base station BS1’s coverage area and connecting to BS2.
Figure 65 WiMax: Mobile Station
WiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber stations
and mobile stations to local base stations. Numerous subscriber stations and mobile stations
connect to the network through a single base station (BS), as in the following figure.
MAX-200HW2 Series User’s Guide
107
Chapter 8 WAN Setup
Figure 66 WiMAX: Multiple Mobile Stations
A base station's coverage area can extend over many hundreds of meters, even under poor
conditions. A base station provides network access to subscriber stations and mobile stations,
and communicates with other base stations.
The radio frequency and bandwidth of the link between the ZyXEL Device and the base
station are controlled by the base station. The ZyXEL Device follows the base station’s
configuration.
8.2.1 Authentication
When authenticating a user, the base station uses a third-party RADIUS or Diameter server
known as an AAA (Authentication, Authorization and Accounting) server to authenticate the
mobile or subscriber stations.
The following figure shows a base station using an AAA server to authenticate mobile station
MS, allowing it to access the Internet.
Figure 67 Using an AAA Server
In this figure, the dashed arrow shows the PKM (Privacy Key Management) secured
connection between the mobile station and the base station, and the solid arrow shows the EAP
secured connection between the mobile station, the base station and the AAA server. See the
WiMAX security appendix for more details.

8.4 Frequency Settings
In a WiMAX network, a mobile or subscriber station must use a radio frequency supported by
the base station to communicate. When the ZyXEL Device looks for a connection to a base
station, it can search a range of frequencies.
Radio frequency is measured in Hertz (Hz).
Table 33 Radio Frequency Conversion
1 kHz = 1000 Hz
1 MHz = 1000 kHz (1000000 Hz)
1 GHz = 1000 MHz (1000000 kHz)
8.4.1 Frequency Ranges
The following figure shows the ZyXEL Device searching a range of frequencies to find a
connection to a base station.
Figure 69 Frequency Ranges
In this figure, A is the WiMAX frequency range. “WiMAX frequency range” refers to the
entire range of frequencies the ZyXEL Device is capable of using to transmit and receive (see
the Product Specifications appendix for details).
In the figure, B shows the operator frequency range. This is the range of frequencies within the
WiMAX frequency range supported by your operator (service provider).
The operator range is subdivided into bandwidth steps. In the figure, each C is a bandwidth
step.
The arrow D shows the ZyXEL Device searching for a connection.
Have the ZyXEL Device search only certain frequencies by configuring the downlink
frequencies. Your operator can give you information on the supported frequencies.
The downlink frequencies are points of the frequency range your ZyXEL Device searches for
an available connection. Use the Site Survey screen to set these bands. You can set the
downlink frequencies anywhere within the WiMAX frequency range. In this example, the
downlink frequencies have been set to search all of the operator range for a connection.
8.4.2 Configuring Frequency Settings
You need to set the ZyXEL Device to scan one or more specific radio frequencies to find an
available connection to a WiMAX base station.
MAX-200HW2 Series User’s Guide

Chapter 8 WAN Setup
Use the WiMAX Frequency screen to define the radio frequencies to be searched for
available wireless connections. See Section 8.4.2.1 on page 113 for an example of using the
WiMAX Frequency screen.
It may take several minutes for the ZyXEL Device to find a connection.
• The ZyXEL Device searches the DL Frequency settings in ascending numerical order,
from [0] to [9].
• If you enter a 0 in a DL Frequency field, the ZyXEL Device immediately moves on to the
next DL Frequency field.
• When the ZyXEL Device connects to a base station, the values in this screen are
automatically set to the base station’s frequency. The next time the ZyXEL Device
searches for a connection, it searches only this frequency. If you want the ZyXEL Device
to search other frequencies, enter them in the DL Frequency fields.

Use these screens to set up the ZyXEL Device on the LAN. You can configure its IP address
and subnet mask, DHCP services, and other subnets. You can also control how the ZyXEL
Device sends routing information using RIP.
9.1 LAN Overview
A Local Area Network (LAN) is a shared communication system to which many computers
are attached. A LAN is usually a computer network limited to the immediate area, such as the
same building or floor of a building.
9.1.1 IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, 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 specifically 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.
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. You
don't need to change the subnet mask computed by the ZyXEL Device unless you are
instructed to do otherwise.

9.1.2 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. You 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 DHCP service is disabled, you must have
another DHCP server on your LAN, or else each computer must be manually configured.
The ZyXEL Device is pre-configured with a pool of IP addresses for the DHCP clients (DHCP
Pool). See the product specifications in the appendices. Do not assign static IP addresses from
the DHCP pool to your LAN computers.
These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), see Section 9.2.2 on page 122.
9.1.3 LAN TCP/IP
The ZyXEL Device has built-in DHCP server capability that assigns IP addresses and DNS
servers to systems that support DHCP client capability.
The LAN parameters of the ZyXEL Device are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), see Section 9.2.2 on page 122.
9.1.4 DNS Server Address
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 without it, you must know the
IP address of a machine before you can access it. The DNS server addresses that you enter in
the DHCP setup 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 first is for an ISP
to tell a customer the DNS server addresses, usually in the form of an information sheet, when
s/he signs up. If your ISP gives you the DNS server addresses, enter them in the DNS Server
fields in DHCP Setup, otherwise, leave them blank.
Some ISPs choose to pass the DNS servers using the DNS server extensions of PPP 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.
If the Primary and Secondary DNS Server fields in the LAN Setup screen are not specified,
for instance, left as 0.0.0.0, the ZyXEL Device tells the DHCP clients that it itself is the DNS
server. When a computer sends a DNS query to the ZyXEL Device, the ZyXEL Device
forwards the query to the real DNS server learned through IPCP and relays the response back
to the computer.
120
MAX-200HW2 Series User’s Guide
Chapter 9 LAN
Please note that DNS proxy works only when the ISP uses the IPCP DNS server 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
LAN Setup screen. This way, the ZyXEL Device can pass the DNS servers to the computers
and the computers can query the DNS server directly without the ZyXEL Device’s
intervention.
9.1.5 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.
• 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.
• 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 (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.
9.1.6 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.
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.
MAX-200HW2 Series User’s Guide
121
Chapter 9 LAN
The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMPv2). 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.

NAT
Use these screens to configure port forwarding and trigger ports for the ZyXEL Device. You
can also enable and disable SIP, FTP, and H.323 ALG.
10.1 NAT Overview
10.1.1 Port Forwarding: Services and Port Numbers
A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or
FTP, that you can make accessible to the outside world even though NAT makes your whole
inside network appear as a single machine to the outside world.
Use the NAT Port Forwarding Screen to forward incoming service requests to the server(s) on
your local network. You may enter a single port number or a range of port numbers to be
forwarded, and the local IP address of the desired server. The port number identifies a service;
for example, web service is on port 80 and FTP on port 21. In some cases, such as for
unknown services or where one server can support more than one service (for example both
FTP and web service), it might be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service
request that does not have a server explicitly designated for it is forwarded to the default
server. If the default is not defined, the service request is simply discarded.
See Appendix F on page 333 for some examples of services.
For example, let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A
in the example), port 80 to another (B in the example) and assign a default server IP address of
192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP
assigns the WAN IP address. The NAT network appears as a single host on the Internet.
Figure 81 Multiple Servers Behind NAT Example
MAX-200HW2 Series User’s Guide
129
Chapter 10 NAT
10.1.2 Trigger Port Forwarding
Some services use a dedicated range of ports on the client side and a dedicated range of ports
on the server side. With regular port forwarding you set a forwarding port in NAT to forward a
service (coming in from the server on the WAN) to the IP address of a computer on the client
side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP
address. In order to use the same service on a different LAN computer, you have to manually
replace the LAN computer's IP address in the forwarding port with another LAN computer's IP
address,
Trigger port forwarding solves this problem by allowing computers on the LAN to
dynamically take turns using the service. The ZyXEL Device records the IP address of a LAN
computer that sends traffic to the WAN to request a service with a specific port number and
protocol (a "trigger" port). When the ZyXEL Device's WAN port receives a response with a
specific port number and protocol ("incoming" port), the ZyXEL Device forwards the traffic
to the LAN IP address of the computer that sent the request. After that computer’s connection
for that service closes, another computer on the LAN can use the service in the same manner.
This way you do not need to configure a new IP address each time you want a different LAN
computer to use the application.
10.1.2.1 Trigger Port Forwarding Example
The following is an example of trigger port forwarding. In this example, J is Jane’s computer
and S is the Real Audio server.
Figure 82 Trigger Port Forwarding Process: Example
1 Jane requests a file from the Real Audio server (port 7070).
2 Port 7070 is a “trigger” port and causes the ZyXEL Device to record Jane’s computer IP
address. The ZyXEL Device associates Jane's computer IP address with the "incoming"
port range of 6970-7170.
3 The Real Audio server responds using a port number ranging between 6970-7170.
4 The ZyXEL Device forwards the traffic to Jane’s computer IP address.
5 Only Jane can connect to the Real Audio server until the connection is closed or times
out. The ZyXEL Device times out in three minutes with UDP (User Datagram Protocol),
or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol).
10.1.2.2 Two Points To Remember About Trigger Ports
1 Trigger events only happen on data that is coming from inside the ZyXEL Device and
going to the outside.
130
MAX-200HW2 Series User’s Guide
Chapter 10 NAT
2 If an application needs a continuous data stream, that port (range) will be tied up so that
another computer on the LAN can’t trigger it.
10.1.3 SIP ALG
Some applications, such as SIP, cannot operate through NAT (are NAT un-friendly) because
they embed IP addresses and port numbers in their packets’ data payload.
Some NAT routers may include a SIP Application Layer Gateway (ALG). An Application
Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323 or FTP) at the
application layer.
A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses
embedded in the data stream. See Section 10.2.5 on page 135 for information on configuring
the ZyXEL Device’s ALG.

VPN Transport
11.1 Overview
This chapter describes the Network > VPN Transport screens.
The ZyXEL Device’s VPN Transport feature allows traffic from multiple users to pass through
the WiMAX network, to the service provider’s router. Each user has his own personal
connection to the service provider, even though there is only a single WiMAX connection.
This allows the service provider to identify which user traffic comes from.
The following figure shows two users (A and B), connecting to the ZyXEL Device (Z)
through a switch (S). Each user has his own connection over the WiMAX network to the
service provider’s router (R).
Figure 88 VPN Transport example
WiMAX
The services available may vary, depending upon the service provider.
VPN stands for “Virtual Private Network”. There are many types of VPN; the type used by the
ZyXEL Device is known as Virtual Private LAN Service, or VPLS.
Unlike some other types of VPN (such as IPSec VPNs) VPLS VPNs do not
use authentication or encryption to secure the data they carry.

11.1.1 What You Can Do in the VPN Transport Screens
• Use the Network > VPN Transport > General screen (see Section 11.2 on page 140) to
turn VPN transport on or off, and to set the VPN transport endpoint (your service
provider’s router).
• Use the Network > VPN Transport > Customer Interface screen (see Section 11.3 on
page 141) to specify which users can use which WiMAX network links.
• Use the Network > VPN Transport > Ethernet Pseudowire screen (see Section 11.5 on
page 143) to configure the links over the WiMAX network between the ZyXEL Device
and the service provider’s router.
• Use the Network > VPN Transport > Statistics screen (see Section 11.7 on page 145) to
view performance information about the VPN transport connections.
11.1.2 What You Need to Know about VPN Transport
Identifying Users
For the ZyXEL Device’s VPN Transport feature to work, it must be able to identify users on
the LAN. It does this by examining VLAN (Virtual Local Area Network) tags.
These tags must be added to the data packets by a switch on the LAN. In the following
example, two users (A and B) are connected to a switch (C). A and B are connected to
different ports on the switch (port 1 and port 2). A and B send untagged packets to the switch.
The switch adds tags to packets depending on the physical port on which they arrive. Packets
arriving on port 1 are given a VLAN ID (VLAN IDentifier) of 1, and packets arriving on port
2 are given a VLAN ID of 2. When the packets reach the ZyXEL Device (D), their source is
identified by examining their VLAN tags.

Ethernet Pseudowires
Because VPLS mimics a simple wired Ethernet connection to your service provider’s router,
the connection between the ZyXEL Device and the peer device is known as an “Ethernet
pseudowire” or “PW”.
The Ethernet pseudowires use MPLS (MultiProtocol Label Switching) virtual circuit labels to
define the connection. In any such pseudowire, the ingress label on one device must be the
same as the egress label on the peer device, as shown in the following figure. A is your ZyXEL
Device and B is your service provider’s router.

Customer Interface Mapping
Once the ZyXEL Device has examined a frame’s VLAN tag, it is able to assign the frame to a
specified path. This is done using a customer interface. The customer interface is simply a set
of information that takes frames from a VLAN and put them on an Ethernet pseudowire, and
vice versa.
In the following example, the ZyXEL Device takes frames tagged with two different VLAN
IDs (10 and 20) and using the customer interfaces, assigns them to specific pseudowires (PW1
and PW2).

The ZyXEL Device has a default customer interface configured for frames that arrive at the
ZyXEL Device without VLAN tags.
11.1.3 Before You Begin
Before you start configuring your ZyXEL Device to use VPN transport, ensure that you have
the following from the service provider.
• The IP address or domain name of the service provider’s edge router.
• Virtual circuit (VC) labels for each Ethernet Pseudowire you want to create.
Also, ensure you know the VLAN IDs (Virtual LAN IDentifiers) of the VLANs on your LAN.

11.8 VPN Transport Technical Reference
This section includes background information about VPN Transport.
11.8.1 Multi-Protocol Label Switching
The ZyXEL Device uses MPLS VPNs to create virtual private LANs. MPLS stands for MultiProtocol Label Switching, and is a packet-switching technology that allows packets with
different VLAN tags to be transported on different paths (known as LSPs, or Label Switched
Paths). Each packet is identified by its VLAN tag and sent to a specific LSP for transport over
the WiMAX network.
146
MAX-200HW2 Series User’s Guide
Chapter 11 VPN Transport
Each LSP has a defined start-point and end-point. Since MPLS creates mono-directional paths
(traffic flows in only one direction), each Ethernet pseudowire uses two LSPs so that traffic
can flow both ways. One LSP carries upstream traffic, and the other carries downstream
traffic.
11.8.2 Generic Routing Encapsulation
In order to transport the VPLS traffic over the WiMAX network, the ZyXEL Device uses the
Generic Routing Encapsulation (GRE) protocol. Like MPLS, GRE is a tunneling protocol that
has specified endpoints. The GRE tunnel is bi-directional, and transports both LSPs. The GRE
tunnel runs across the WiMAX network between the ZyXEL Device and your service
provider’s router.
It is necessary to encapsulate the Ethernet pseudowire since the WiMAX connection is IPonly. MPLS information is carried in a packet’s Ethernet header and, without encapsulation,
would be stripped from the packet prior to the packet’s transmission over the WiMAX link.
The following figure shows the VPLS connection between your ZyXEL Device (A) and your
service provider’s router (B), consisting of GRE-encapsulated Ethernet pseudowire traffic.

SIP
Use these screens to set up your SIP accounts and to configure QoS settings.
12.1 SIP Overview
12.1.1 Introduction to VoIP
VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you
to make phone calls and send faxes over the Internet at a fraction of the cost of using the
traditional circuit-switched telephone network. You can also use servers to run telephone
service applications like PBX services and voice mail. Internet Telephony Service Provider
(ITSP) companies provide VoIP service. A company could alternatively set up an IP-PBX and
provide it’s own VoIP service.
Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to
handle a telephone call. VoIP can use advanced voice coding techniques with compression to
reduce the required bandwidth.
12.1.2 Introduction to SIP
The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that
handles the setting up, altering and tearing down of voice and multimedia sessions over the
Internet.
SIP signaling is separate from the media for which it handles sessions. The media that is
exchanged during the session can use a different path from that of the signaling. SIP handles
telephone calls and can interface with traditional circuit-switched telephone networks.
12.1.3 SIP Identities
A SIP account uses an identity (sometimes referred to as a SIP address). A complete SIP
identity is called a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the
SIP account in a way similar to the way an e-mail address identifies an e-mail account. The
format of a SIP identity is SIP-Number@SIP-Service-Domain.
12.1.3.1 SIP Number
The SIP number is the part of the SIP URI that comes before the “@” symbol. A SIP number
can use letters like in an e-mail address (johndoe@your-ITSP.com for example) or numbers
like a telephone number (1122334455@VoIP-provider.com for example).
MAX-200HW2 Series User’s Guide
149
Chapter 12 SIP
12.1.3.2 SIP Service Domain
The SIP service domain of the VoIP service provider (the company that lets you make phone
calls over the Internet) is the domain name in a SIP URI. For example, if the SIP address is
1122334455@VoIP-provider.com, then “VoIP-provider.com” is the SIP service domain.
12.1.4 SIP Call Progression
The following figure displays the basic steps in the setup and tear down of a SIP call. A calls
B.
Table 57 SIP Call Progression
1. INVITE
2. Ringing
3. OK
4. ACK
5.Dialogue (voice traffic)
6. BYE
7. OK
1 A sends a SIP INVITE request to B. This message is an invitation for B to participate in
a SIP telephone call.
2 B sends a response indicating that the telephone is ringing.
3 B sends an OK response after the call is answered.
4 A then sends an ACK message to acknowledge that B has answered the call.
5 Now A and B exchange voice media (talk).
6 After talking, A hangs up and sends a BYE request.
7 B replies with an OK response confirming receipt of the BYE request and the call is
terminated.
12.1.5 SIP Client Server
SIP is a client-server protocol. A SIP client is an application program or device that sends SIP
requests. A SIP server responds to the SIP requests.
When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A
SIP client could be a computer or a SIP phone. One device can act as both a SIP client and a
SIP server.
12.1.5.1 SIP User Agent
A SIP user agent can make and receive VoIP telephone calls. This means that SIP can be used
for peer-to-peer communications even though it is a client-server protocol. In the following
figure, either A or B can act as a SIP user agent client to initiate a call. A and B can also both
act as a SIP user agent to receive the call.
150
MAX-200HW2 Series User’s Guide
Chapter 12 SIP
Figure 99 SIP User Agent
12.1.5.2 SIP Proxy Server
A SIP proxy server receives requests from clients and forwards them to another server.
In the following example, you want to use client device A to call someone who is using client
device C.
1 The client device (A in the figure) sends a call invitation to the SIP proxy server (B).
2 The SIP proxy server forwards the call invitation to C.
Figure 100 SIP Proxy Server
12.1.5.3 SIP Redirect Server
A SIP redirect server accepts SIP requests, translates the destination address to an IP address
and sends the translated IP address back to the device that sent the request. Then the client
device that originally sent the request can send requests to the IP address that it received back
from the redirect server. Redirect servers do not initiate SIP requests.
In the following example, you want to use client device A to call someone who is using client
device C.
1 Client device A sends a call invitation for C to the SIP redirect server (B).
2 The SIP redirect server sends the invitation back to A with C’s IP address (or domain
name).
3 Client device A then sends the call invitation to client device C.
MAX-200HW2 Series User’s Guide
151
Chapter 12 SIP
Figure 101 SIP Redirect Server
12.1.5.4 SIP Register Server
A SIP register server maintains a database of SIP identity-to-IP address (or domain name)
mapping. The register server checks your user name and password when you register.
12.1.6 RTP
When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to
handle voice data transfer. See RFC 1889 for details on RTP.
12.1.7 NAT and SIP
The ZyXEL Device must register its public IP address with a SIP register server. If there is a
NAT router between the ZyXEL Device and the SIP register server, the ZyXEL Device
probably has a private IP address. The ZyXEL Device lists its IP address in the SIP message
that it sends to the SIP register server. NAT does not translate this IP address in the SIP
message. The SIP register server gets the ZyXEL Device’s IP address from inside the SIP
message and maps it to your SIP identity. If the ZyXEL Device has a private IP address listed
in the SIP message, the SIP server cannot map it to your SIP identity. See Chapter 10 on page
129 for more information about NAT.
Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to allow
the ZyXEL Device to list its public IP address in the SIP messages.
12.1.7.1 SIP ALG
See Section 10.1.3 on page 131.
