1.3 Good Habits for Managing the WiMAX
Modem
Do the following things regularly to make the WiMAX Modem more secure and to
manage the WiMAX Modem 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 WiMAX Modem
becomes unstable or even crashes. If you forget yo ur password, you will have to
reset the WiMAX Modem to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the WiMAX
Modem. You could simply restore your last configuration.

Use these screens to configure or view LAN, DHCP Client and WAN settings.
3.1.1 What You Can Do in This Chapter
•The Set IP Address (LAN 設定 ) screen (Section 3.2 on page 32) lets you
configure the WiMAX Modem’s IP address and subnet mask.
•The DHCP Client (DHCP 用戶端 ) screen (Section 3.3 on page 33) lets you view
all DHCP client information.
•The Time Setting (時間設定) screen (Section 3.4 on page 35) lets you configure

3.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
LAN
A Local Area Network, or a shared communication system to which many
computers are attached. A LAN, as its name implies, is limited to a local area such
as a home or office environment. LANs have different topologies, the most
common being the linear bus and the star configuration.
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
The subnet mask specifies the network number portion of an IP address. Your
device will compute the subnet mask automatically based on the IP Address that
User’s Guide
31
Chapter 3 The Setup Screens
you entered. Y ou do not need to change the computer subnet mask unless you are
instructed to do so.
DHCP
Your WiMAX Modem can act as a DHCP (Dynamic Host Configuration Protocol)
server that can assign your LAN computers an IP address, subnet mask, DNS and
other routing information when its LAN DHCP feature is turned on.
Daytime
A network protocol used by devices for debugging and time measurement. A
computer can use this protocol to set its internal clock but only if it knows in which
order the year, month, and day are returned by the server. Not all servers use the
same format.
Time
A network protocol for retrieving the current time from a server. The computer
issuing the command compares the time on its clock to the information returned
by the server, adjusts itself automatically for time zone differences, then
calculates the difference and corrects itself if there has been any temporal drift.
NTP
NTP stands for Network Time Protocol. It is employed by devices connected to the
Internet in order to obtain a precise time setting from an official time server.
These time servers are accurate to within 200 microseconds.
3.1.3 Before You Begin
• Make sure that you have made all the appropriate hardware connections to the
WiMAX Modem, as described in the Quick Start Guide.
• Make sure that you have logg ed in to the web confi gurator at least one time and

3.4.1 Pre-Defined NTP Time Servers List
The WiMAX Modem uses a pre-defined list of NTP time servers if you do not
specify a time server or it cannot synchronize with the time server you specified.
It can use this list regardless of the time protocol you select.
When the WiMAX Modem uses the list, it randomly selects one server and tries to
synchronize with it. If the synchronization fails, then it goes through the rest of
the list in order until either it is successful or all the pre-defined NTP time servers
have been tried.
The WiMAX Modem automatically resets the time in the following circumstances:
• When the device starts up, such as when you press the Power button.
• When you click Apply (套用 ) in the SETUP (設定 ) > Time Setting (時間設定)
screen.
• Once every 24-hours after starting up.

The LAN Configuration Screens
5.1 Overview
Use the ADVANCED > LAN Configuration screens to set up the WiMAX Modem
on the LAN. You can configure its IP addr ess and subnet mask, DHCP services, and
other subnets. You can also control how the WiMAX Modem sends routing
information using RIP.
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.
5.1.1 What You Can Do in This Chapter
•The DHCP Setup screen (Section 5.2 on page 46) lets you enable, disable, and
configure the DHCP server in the WiMAX Modem.
•The Sta tic DHCP sc reen (Section 5.3 on page 47) lets you assign specific IP
addresses to specific computers on the LAN.
•The IP Alias screen (Section 5.4 on page 49) lets you add subnets on the LAN
port. You can also control what routing information is sent and received by each
subnet.
•The IP Static Route screen (Section 5.5 on page 51) lets you examine the
static routes configured in the WiMAX Modem.
•The Other Settings screen (Section 5.6 on page 53) lets you control the
routing information that is sent and received by each subnet assign specific IP
addresses to specific computers on the LAN.
5.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
IP Address
User’s Guide
IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to
45
Chapter 5 The LAN Configuration Screens
communicate across the network. These networking devices are also known as
hosts.
Subnet Masks
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.
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
without it, you must know the IP address of a networking device before you can
access it.
DHCP
A DHCP (Dynamic Host Configuration Protocol) server can assign your WiMAX
Modem an IP address, subnet mask, DNS and other routing information when it’s
turned on.

5.7 Technical Reference
The following section contains additional technical information about the WiMAX
Modem features described in this chapter.
5.7.1 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 WiMAX Modem. 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 192.168.100.1 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.
54
User’s Guide
Once you have decided on the network number, pick an IP address that is easy to
remember, for instance, 192.168.100.1, for your WiMAX Modem, 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
WiMAX Modem 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 WiMAX Modem unless you are instructed to do otherwise.
5.7.2 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 WiMAX Modem as a DHCP server or disable it. When configured as a
server, the WiMAX Modem 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.
Chapter 5 The LAN Configuration Screens
The WiMAX Modem 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.
These parameters should work for the majority of installations. If your ISP gives
you explicit DNS server address(es), see Section 5.3 on page 47.
5.7.3 LAN TCP/IP
The WiMAX Modem 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 WiMAX Modem are preset in the factory with the
following values:
• IP address of 192.168.100.1 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 5.3 on page 47.
5.7.4 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.
User’s Guide
55
Chapter 5 The LAN Configuration Screens
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 serv ers are conv eyed through IPCP
negotiation. The WiMAX Modem 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 WiMAX Modem tells the DHCP
clients that it itself is the DNS server. When a computer sends a DNS query to the
WiMAX Modem, the WiMAX Modem forwards the query to the real DNS server
learned through IPCP and relays the response back to the computer.
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
WiMAX Modem can pass the DNS servers to the computers and the computers can
query the DNS server directly without the WiMAX Modem’s intervention.
5.7.5 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 WiMAX Modem will broadcast its routing table periodically and
incorporate the RIP information that it receives.
• In Only - the WiMAX Modem will not send any RIP packets but will accept all
RIP packets received.
• Out Only - the WiMAX Modem will send out RIP packets but will not accept any
RIP packets received.
• None - the WiMAX Modem will not send any RIP packets and will ignore any RIP
packets received.
56
The Version field controls the format and the broadcasting method of the RIP
packets that the WiMAX Modem sends (it recog nizes both formats when
receiving). RIP-1 is universally supported; but RIP-2 carries more information.
User’s Guide
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.
5.7.6 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 host s must join t he 224.0.0.1 group in order
to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers
group.
Chapter 5 The LAN Configuration Screens
The WiMAX Modem supports both IGMP version 1 (IGMP-v1) and IGMP version 2
(IGMP-v2). At start up, the WiMAX Modem queries all directly connected
networks to gather group membership. After that, the WiMAX Modem periodically
updates this information. IP multicasting can be enabled/disabled on the WiMAX
Modem LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.

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 some security in the AP screen.
6.1.2 What You Need to Know About WIFI
Wireless Basics
• Every device in the same wireless network must use the same Service Set
IDentity (SSID).
The SSID is the name of the wireless network.
• 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.
Wireless Network Construction
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can
connect with numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and
wireless clients, extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or
more wireless clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless
clients connect to one another in order to exchange information.
Wired Equivalent Privacy (WEP)
60
WEP (Wired Equivalent Privacy) encrypts data transmitted between wired and
wireless networks to keep the transmission private. Although one of the original
wireless encryption protocols, WEP is also the weakest. Many people use it strictly
to deter unintentional usage of their wireless network by outsiders.
Authentication Type
User’s Guide
Chapter 6 The WIFI Configuration Screen
The IEEE 802.11b/g standard describes a simple authentication method between
the wireless stations and AP. Three authentication types are defined: Auto, Open
and Shared. The WiMAX Modem supports the WEP (Open) and WEP (Shared)
authentication types.
• Open mode is implemented for ease-of-use and when security is not an issue.
The wireless station and the AP or peer computer do not share a secret key.
Thus the wireless stations can associate with any AP or peer computer and listen
to any transmitted data that is not encrypted.
• Shared mode involves a shared secret key to authenticate the wireless station
to the AP or peer computer. This requires you to enable the wireless LAN
security and use same settings on both the wireless station and the AP or peer
computer.
Wi-Fi Protected Access (WPA)
WPA encrypts data transmitted between wired and wireless networks to keep the
transmission private. It affords vastly stronger security than its lower-tier
counterpart, WEP (Wired Equivalent Privacy). It comes in two different flavors:
WPA and WPA2. Always try to use WPA2 as it implements the full version of the
security standard while WPA does not.
WPA2
WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger
encryption, authentication and key management than WPA. It includes two data
encryption algorithms, Temporal Key Integrity Protocol (TKIP) and Advanced
Encryption Standard (AES) in the Counter mode with Cipher block chaining
Message authentication Code Protocol (CCMP). WPA2 reduces the number of key
exchange messages from six to four (CCMP 4-way handshake) and shortens the
time required to connect to a network. Other WPA2 authentication features that
are different from WPA include key caching and pre-authentication. These two
features are optional and may not be implemented in all wireless devices. See also
WPA.
Pre-Shared Key (PSK)
A pre-shared key is a password shared between the server and the client that
unlocks the algorithm used to encrypt the data traffic between them. Without the
proper password, the client and the server cannot communicate.

Security stops unauthorized devices from using the wireless network. It can also
protect the information that is sent in the wireless network.Use the stron g es t
security that every wireless client in the wireless network supports.
Table 17 Wireless Security Levels

MAC Address Filtering
WEP Encryption
IEEE 802.1x EAP with RADIUS Server
• WPA2-PSK and WPA-PSK do not employ user authentication and are known as
the personal version of WPA.
• WEP is better than no security, but it is still possible for unauthorized devices to
figure out the original information pretty quickly.
AES
Advanced Encryption Standard is method of data encryption that uses a secret
key. AES may use a 128-bit, 192-bit or 256-bit key. AES is faster than 3DES.
TKIP
Temporal Key Integrity Protocol (TKIP) is an encryption protocol that uses 128-bit
keys that are dynamically generated and distributed by the authentication server.
TKIP regularly changes and rotates the encryption keys so that the same
encryption key is never used twice.
62
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”.
User’s Guide
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.

6.1.3 Before You Start
Before you start using these screens, ask yourself the following questions. See
Section 6.1.2 on page 60 if some of the terms used here do not make sense to
you.
• What wireless standards do the other wireless devices support (IEEE 802.11g,
for example)? What is the most appropriate standard to use?
Chapter 6 The WIFI Configuration Screen
• What security options do the other wireless devices support (WPA-PSK, for
example)? What is the best one to use?
• Do the other wireless devices support WPS (Wi-Fi Protected Setup)? If so, you
can set up a well-secured network very easily.
Even if some of your devices support WPS and some do not, you can use WPS to
set up your network and then add the non-WPS devices manually, although this
is somewhat more complicated to do.
• What advanced options do you want to configure, if any? If you want to
configure advanced options such as Qualit y of Service, ensure that you know
precisely what you want to do. If you do not want to configure advanced
options, leave them alone.

The following table describes some wireless network terms and acronyms used in
the WiMAX Modem’s Web Configurator.
Table 23 Additional Wireless Terms
TERMDESCRIPTION
RTS/CTS ThresholdIn a wireless network which covers a large area, wireless devices
are sometimes not aware of each other’s presence. This may cause
them to send information to the AP at the same time and result in
information colliding and not getting through.
By setting this value lower than the default value, the wireless
devices must sometimes get permission to send information to the
WiMAX Modem. The lower the value, the more often the devices
must get permission.
If this value is greater than the fragmentation threshold value (see
below), then wireless devices never have to get permission to send
information to the WiMAX Modem.
PreambleA preamble affects the timing in your wireless network. There are
two preamble modes: long and short.If a device uses a different
preamble mode than the WiMAX Modem does, it cannot
communicate with the WiMAX Modem.
AuthenticationThe process of verifying whether a wireless device is allowed to use
the wireless network.
Fragmentation
Threshold
A small fragmentation threshold is recommended for busy networks,
while a larger threshold provides faster performance if the network
is not very busy.
Chapter 6 The WIFI Configuration Screen
6.4.2 Wireless Security Overview
The following sections introduce different types of wireless s ecurity you can set up
in the wireless network.
6.4.2.1 SSID
Normally , the WiMAX Modem acts lik e a beacon and regularly broadcasts the SSID
in the area. Yo u can hide the S SID instead, in which case the WiMAX Modem 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 wireless devices to get the SSID. In addition, unauthorized wireless
devices can still see the in formation that is sent in the wireless network.
6.4.2.2 MAC Address Filter
Every device that can use a wireless network has a unique identification number,
called a MAC address.
1
A MAC address is usually written using twelve hexadecimal
User’s Guide
71
Chapter 6 The WIFI Configuration Screen
characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC
address for each device in the wireless network, see the device’s User’s Guide or
other documentation.
You can use the MAC address filter to tell the WiMAX Modem which devices are
allowed or not allowed to use the wireless network. If a device is allowed to use
the wireless network, it still has to have the correct information (SSID, channel,
and security). If a device is not allowed to use the wireless network, it does not
matter if it has the correct information.
This type of security does not protect the inf o rm at ion that is sent in the wireless
network. Furthermore, there are ways f or unauthorized wireless devices to get the
MAC address of an authorized device. Then, they can use that MAC address to use
the wireless network.
6.4.2.3 User Authentication
Authentication is the process of verifying whether a wireless device is allowed to
use the wireless network. Y ou can make every user log in to the wireless network
before they can use it. However, every device in the wireless network has to
support IEEE 802.1x to do this.
For wireless networks, you can store the user names and passwords for each user
in a RADIUS server . This is a server used in businesses more than in homes. If you
do not have a RADIUS server, you cannot set up user names and passwords for
your users.
Unauthorized wireless 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.
6.4.2.4 Encryption
Wireless networks can use encryption to protect the informat ion 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.
72
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.
User’s Guide
Chapter 6 The WIFI Configuration Screen
The types of encryption you can choose depend on the type of authentication.
(See Section 6.4.2.3 on page 72 for information about this.)
Table 24 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION RADIUS SERVER
WeakestNo Security
Static WEP
WPA-PSK
WPA
StrongestWPA2-PSKWPA2
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 device in the
wireless network supports. For example, suppose you have a wireless network
with the WiMAX Modem and you do not have a RADIUS serv er. Therefore, there is
no authentication. Suppose the wireless network has two devices. Device A only
supports WEP, and device B supports WEP and WPA. Therefore, you should set up
Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. The other types of encryption are better than none at all, but it is still
possible for unauthorized wireless devices to figure out the original information
pretty quickly.
When you select WPA2 or WPA2-PSK in your WiMAX Modem, you can also select
an option (WPA compatible) to support WPA as well. In this case, if some of the
devices 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 WiMAX Modem.
Many types of encryption use a key to protect the information in the wireless
network. The longer the key, the stronger the encryption. Every device in the
wireless network must have the same key.
6.4.3 MBSSID
Traditionally, you needed to use different APs to configure different Basic Service
Sets (BSSs). As well as the cost of buying extr a APs, there w as also the possibilit y
of channel interference. The WiMAX Modem’s MBSSID (Multiple Basic Service Set
IDentifier) function allows you to use one access point to provide several BSSs
simultaneously. You can then assign varying QoS priorities and/or security modes
to different SSIDs.
User’s Guide
73
Chapter 6 The WIFI Configuration Screen
Wireless devices can use different BSSIDs to associate with the same AP.
6.4.3.1 Notes on Multiple BSSs
• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use different keys for different BSSs. If two wireless devices have
different BSSIDs (they are in different BSSs), but have the same keys, they
may hear each other’s communications (but not communicate with each other).
• MBSSID should not replace but rather be used in conjunction with 802.1x
security.
6.4.4 Wireless Distribution System (WDS)
The WiMAX Modem can act as a wireless network bridge and establish WDS
(Wireless Distribution System) links with other APs. You need to know the MAC
addresses of the APs you want to link to. Once the security settings of peer sides
match one another, the connection between devices is made.
At the time of writing, WDS security is compatible with other ZyXEL access points
only. Refer to your other access point’s documentation for details.
The following example illustrates how WDS link works between APs. Notebook
computer A is a wireless client connecting to access point AP 1. AP 1 has no
wired Internet connection, but can establish a WDS link with access point AP 2,
which does. When AP 1 has a WDS link with AP 2, the notebook computer can
access the Internet through AP 2.
Figure 25 WDS Link Example

AP 1
6.4.5 WiFi Protected Setup
Your WiMAX Modem supports WiFi Protected Setup (WPS), which is an easy w ay to
set up a secure wireless network. WPS is an industry standard specification,
defined by the WiFi Alliance.
WPS allows you to quickly set up a wireless network with strong security, without
having to configure security settings manually. Each WPS connection works
between two devices. Both devices must support WPS (check each device’s
documentation to make sure).
WDS
AP 2
74
User’s Guide
Depending on the devices you have, you can either press a button (on the device
itself , or in its configuration utility) or enter a PIN (a unique P ersonal Identification
Number that allows one device to authenticate the other) in each of the two
devices. When WPS is activated on a device, it has two minutes to find another
device that also has WPS activated. Then, the two devices connect and set up a
secure network by themselves.
6.4.5.1 Push Button Configuration
WPS Push Button Configuration (PBC) is in itiated by pressing a button on each
WPS-enabled device, and allowing them to connect automatically. You do not need
to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS
PBC button in their configuration utilities instead of or in addition to the physical
button.
Take the following steps to set up WPS using the button.
Chapter 6 The WIFI Configuration Screen
1Ensure that the two devices you want to set up are within wireless range of one
another.
2Look for a WPS button on each device. If the device does not have one, log into its
configuration utility and locate the button (see the device’s User’ s Guide for how to
do this). The WiMAX Modem’s WPS button is in the rear panel as shown next.
Figure 26 The WPS Button on the WiMAX Modem
3Press the button on one of the devices (it doesn’t matter which). For the WiMAX
Modem you must press the WPS button for more than three seconds.
4Within two minutes, press the button on the other device. The registrar sends the
network name (SSID) and security key throug h an secure connection to the
enrollee.
User’s Guide
If you need to make sure that WPS worked, check the list of associated wireless
clients in the AP’s configuration utility. If you see the wireless client in the list,
WPS was successful.

The WAN Configuration Screens
7.1 Overview
Use the ADVANCED > WAN Configuration screens to set up your WiMAX
Modem’s Wide Area Network (WAN) or Internet features.
A Wide Area Network (or WAN) links geographically dispersed locations to other
networks or the Internet. A WAN configuration can include switched and
permanent telephone circuits, terrestrial radio systems and satellite systems.
7.1.1 What You Can Do in This Chapter
•The Internet Connection screen (Section 7.2 on page 79) lets you set up your
WiMAX Modem’s Internet settings.
•The W iMAX Configuration screen (Section 7.3 on page 82) lets set up the
frequencies used by your WiMAX Modem.
7.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
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
User’s Guide
77
Chapter 7 The WAN Configuration Screens
example). The following figure shows an MS-equipped notebook computer MS1
moving from base station BS1’s coverage area and connecting to BS2.
Figure 27 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 singl e base station ( BS), as
in the following figure.
Figure 28 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 t he WiMAX Modem and the
base station are controlled by the base station. The WiMAX Modem follows the
base station’s configur ation.
Authentication
When authenticating a user, the base station uses a third-party RADIUS or
Diameter server known as an AAA (Authentication, Authorizat ion and Ac counting)
server to authenticate the mobile or subscriber stations.

Chapter 7 The WAN Configuration Screens
The following figure shows a base station using an AAA server to authenticate
mobile station MS, allowing it to access the Internet.

makes your whole inside network appear as a single machine to the outside world.
Use the ADVANCED ( 進階 ) > NAT Configuration (NAT 設定 ) > 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, we b serv ice 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.
Chapter 8 The NAT Configuration Screens
For example, let's say you want to assig n 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.

Enter the port number or range of port numbers you want to forward to
the specified server.
To forward one port number, enter the port number in the Start Port
and End Port fields.
To forward a range of ports,
• enter the port number at the beginning of the range in the Start Port field
• enter the port number at the end of the range in the End Port field.
Enter the IP address of the server to which to forward packets for the
selected port number(s). This server is usually on the LAN.
8.4 Trigger Port
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,
Tr i g ger port forwarding solves this problem by allowi ng c om puters on the LAN to
dynamically take turns using the service. The WiMAX Modem 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 WiMAX Modem's
WAN port receives a response with a specific port number and protocol
("incoming" port), the WiMAX Modem 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.

8.4.1 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 39 Trigger Port Forwarding Example
1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a “trigger” port and causes the WiMAX Modem to record Jane’s
computer IP address. The WiMAX Modem associates Jane's computer IP address
with the "incoming" port range of 6970-7170.
96
3The Real Audio server responds using a p ort number ranging between 6970-7170.
4The WiMAX Modem forwards the traffic to Jane’s computer IP address.
User’s Guide
Chapter 8 The NAT Configuration Screens
5Only Jane can connect to the Real Audio server until the connection is closed or
times out. The WiMAX Modem times out in three minutes with UDP (User
Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet
Protocol).
Two points to remember about trigger ports:
1Trigger events only happen on data that is coming from inside the WiMAX Modem
and going to the outside.
2If 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.

9.1.1 What You Can Do in This Chapter
•The Dynamic DNS screen (Section 9.2 on page 100) lets you set up the WiMAX
Modem as a dynamic DNS client.
•The Firmware screen (Section 9.3 on page 102) lets you upload new firmware
to the WiMAX Modem.
•The Configuration screen (Section 9.4 on page 104) lets you back up or
restore the configuration of the WiMAX Modem.
•The Restart screen (Section 9.5 on page 105) lets you restart your WiMAX
Modem from within the web configurator.
9.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
System Name
The System Name is often used for identification purposes. Because some ISPs
check this name you should enter your computer's "Computer Name".
• In Windows 2000: Click Start > Settings > Control Panel and then doubleclick the System icon. Select the Network Identification tab and then click
the Properties button. Note the entry for the Computer Name field and enter
it as the System Name.
• In Windows XP: Click Start > My Computer > View system information and
then click the Computer Name tab. Note the entry in the Full computer name field and enter it as the WiMAX Modem System Name.
User’s Guide

Chapter 9 The System Configuration Screens
Domain Name
The Domain Name entry is what is propagated to the DHCP clients on the LAN. If
you leave this blank, the domain name obtained by DHCP from the ISP is used.
While you must enter the host name (System Name) on each individual computer,
the domain name can be assigned from the WiMAX Modem via DHCP.
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 WiMAX Modem can get the DNS server addresses in the following ways:
1The ISP tells you the DNS server addresses, usually in the form of an information
sheet, when you sign up. If your ISP g i ves you DNS server addresses, enter them
in the DNS Server fields in the SYSTEM General screen.
2If the ISP did not give you DNS server information, leave the DNS Server fields in
the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the
DNS server IP addresses.
9.2 Dynamic DNS
Dynamic DNS allows you to update your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, CUSeeMe, etc.). You can also access your FTP server or Web site on your own
computer using a domain name (for instance myhost.dhs.org, where myhost is a
name of your choice) that will never change instead of using an IP address that
changes each time you reconnect. Your friends or relatives will always be able to
call you even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with
www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP
server that would still like to have a domain name. The Dynamic DNS service
provider will give you a password or key.
100
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be
aliased to the same IP address as yourhost.dyndns.org. This feature is useful if
you want to be able to use, for example, www.yourhost.dyndns. org and still reach
your hostname.
