CHAPTER 1
Getting Started
1.1 About Your WiMAX Modem
The WiMAX Modem has a built-in switch and one phone port. It allows you to
access the Internet by connecting to a WiMAX wireless network.
You can use a traditional analog telephone to make Internet calls using the WiMAX
Modem’s Voice over IP (VoIP) communication capabilities.
You can configure firewall and content filtering 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 21 on page 223 for a complete list of features for your model.
1.1.1 WiMAX Internet Access
Connect your computer or network to the WiMAX Modem for WiMAX Internet
access. See the Quick Start Guide for instructions on hardware connection.
In a wireless metropolitan area network (MAN), the WiMAX Modem connects to a
WiMAX base station (BS) for Internet access.
The following diagram shows a notebook computer equipped with the WiMAX
Modem connecting to the Internet through a WiMAX base station (marked BS).
Figure 1 Mobile Station and Base Station
When the firewall is on, all incoming traffic from the Internet to your network is
blocked unless it is initiated from your network.
User s Guide
31
Chapter 1Getting Started
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 Make Calls via Internet Telephony Service Provider
In a home or small office environment, you can use the WiMAX Modem to make
and receive the following types of VoIP telephone calls:
• Peer-to-Peer calls - Use the WiMAX Modem to make a call directly to the
recipient’s IP address without using a SIP proxy server.
Figure 2 WiMAX Modem s VoIP Features - Peer-to-Peer Calls
32
• Calls via a VoIP service provider - The WiMAX Modem sends your call to a VoIP
service provider’s SIP server which forwards your calls to either VoIP or PSTN
phones.

1.3 Good Habits for Managing the Device
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 your 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.

CHAPTER 2
Introducing the Web
Configurator
2.1 Overview
The web configurator is an HTML-based management interface that allows easy
device set up and management via any web browser that supports: HTML 4.0,
CSS 2.0, and JavaScript 1.5, and higher. The recommended screen resolution for
using the web configurator is 1024 by 768 pixels and 16-bit color, or higher.
In order to use the web configurator you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled
by default in many operating systems and web browsers.
• JavaScript (enabled by default in most web browsers).
• Java permissions (enabled by default in most web browsers).
See the Appendix C on page 263 for more information on configuring your web
browser.
2.1.1 Accessing the Web Configurator
1 Make sure your WiMAX Modem hardware is properly connected (refer to the Quick
Start Guide for more information).
2 Launch your web browser.
3 Enter the IP address on the UG cover as the URL.
4 A user name and password screen displays. Enter the default user or admin
account name and password (on the UG cover), then click Login. Click Clear to
clear the password field. If you have changed the password, enter your password
and click Login.
User s Guide

5.1 Overview
Use these screens to configure or view LAN, DHCP Client and WAN settings.
5.1.1 What You Can Do in This Chapter
• The Set IP Address screen (Section 5.2 on page 54) lets you configure the
WiMAX Modem’s IP address and subnet mask.
• The DHCP Client screen (Section 5.3 on page 55) to view connection
information for clients configured by the WiMAX Modem’s internal DHCP server.
• The Time Setting screen (Section 5.4 on page 56) lets you configure your
WiMAX Modem’s time and date keeping settings.
5.1.2 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

Chapter 5The Setup Screens
you entered. You do not need to change the computer subnet mask unless you are
instructed to do so.
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.
5.1.3 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 logged in to the web configurator at least one time and
changed your password from the default, as described in the Quick Start Guide.

The LAN Configuration Screens
6.1 Overview
Use the ADVANCED > LAN Configuration screens to set up the WiMAX Modem
on the LAN. You can configure its IP address 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.
6.1.1 What You Can Do in This Chapter
• The DHCP Setup screen (Section 6.2 on page 60) lets you enable, disable, and
configure the DHCP server in the WiMAX Modem.
• The Static DHCP screen (Section 6.3 on page 62) lets you assign specific IP
addresses to specific computers on the LAN.
• The IP Static Route screen (Section 6.4 on page 63) lets you examine the
static routes configured in the WiMAX Modem.
• The Other Settings screen (Section 6.5 on page 65) lets you control the
routing information that is sent and received by each subnet assign specific IP
addresses to specific computers on the LAN.
6.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.

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

Chapter 6The LAN Configuration Screens
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.

The metric represents the "cost of transmission". A router determines
the best route for transmission by choosing a path with the lowest
"cost". The smaller the metric, the lower the "cost". RIP uses hop count
as the measurement of cost, where 1 is for a directly-connected
network. The metric must be 1-15; if you use a value higher than 15,
the routers assume the link is down.

computer) and broadcasting (sending packets to every computer).
• None - The WiMAX Modem does not support multicasting.
• IGMP-v1 - The WiMAX Modem supports IGMP version 1.
• IGMP-v2 - The WiMAX Modem supports IGMP version 2.
Multicasting can improve overall network performance. However, it
requires extra processing and generates more network traffic. In
addition, other computers on the LAN have to support the same version
of IGMP.

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 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.
Chapter 6The LAN Configuration Screens
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 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. You don't need to change the subnet mask computed by
the WiMAX Modem unless you are instructed to do otherwise.
6.6.2 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients to obtain TCP/IP configuration at start-up from a server. 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.
The WiMAX Modem 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 6.3 on page 62.
User s Guide
67
Chapter 6The LAN Configuration Screens
6.6.3 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.
These parameters should work for the majority of installations. If your ISP gives
you explicit DNS server address(es), see Section 6.2 on page 60.
6.6.4 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 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
notspecified, 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.

User s Guide
6.6.5 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers. The RIP Direction field controls the sending and
receiving of RIP packets. When set to:
• Both - the 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.
The Version field controls the format and the broadcasting method of the RIP
packets that the WiMAX Modem 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.
Chapter 6The LAN Configuration Screens
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.
6.6.6 Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1
sender - 1 recipient) or Broadcast (1 sender - everybody on the network).
Multicast delivers IP packets to a group of hosts on the network - not everybody
and not just 1.
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.
User s Guide
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

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).
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 24 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.
Figure 25 WiMAX: Multiple Mobile Stations
72
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 WiMAX Modem and the
base station are controlled by the base station. The WiMAX Modem follows the
base station’s configuration.
User s Guide
Chapter 7The WAN Configuration Screens
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 26 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.

When computers use peer to peer applications, such as file
sharing applications, they may use a large number of NAT
sessions. If you do not limit the number of NAT sessions a single
client can establish, this can result in all of the available NAT
sessions being used. In this case, no additional NAT sessions can

8.3 Port Forwarding
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 ADVANCED > NAT Configuration > 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.

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,
Trigger port forwarding solves this problem by allowing computers 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 37 Trigger Port Forwarding Example
1 Jane requests a file from the Real Audio server (port 7070).
2 Port 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.
3 The Real Audio server responds using a port number ranging between 6970-7170.
4 The WiMAX Modem 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 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:
1 Trigger events only happen on data that is coming from inside the WiMAX Modem
and going to the outside.
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.

8.5 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.
Click ADVANCED > NAT Configuration > ALG to enable and disable SIP (VoIP),
FTP (file transfer), and H.323 (audio-visual) ALG in the WiMAX Modem.

settings, and set the current date and time.
9.1.1 What You Can Do in This Chapter
• The General screen (Section 9.2 on page 95) lets you change the WiMAX
Modem’s mode, set up its system name, domain name, idle timeout, and
administrator password.
• The Dynamic DNS screen (Section 9.3 on page 96) lets you set up the WiMAX
Modem as a dynamic DNS client.
• The Firmware screen (Section 9.4 on page 98) lets you upload new firmware to
the WiMAX Modem.
• The Configuration screen (Section 9.5 on page 100) lets you back up or
restore the configuration of the WiMAX Modem.
• The Restart screen (Section 9.6 on page 101) lets you restart your WiMAX
Modem from within the web configurator.
• The Bridge screen (Section 9.7 on page 102) lets you set the WiMAX Modem to
either Bridge or Router mode.
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".
User s Guide
93
Chapter 9The System Configuration Screens
• In Windows 2000: Click Start > Settings > Control Panel and then double-
click 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.
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. 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:
1 The ISP tells you the DNS server addresses, usually in the form of an information
sheet, when you sign up. If your ISP gives you DNS server addresses, enter them
in the DNS Server fields in the SYSTEM General screen.
2 If 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.

9.3 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.
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.
Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.
