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 237 for a complete list of features for your model.

Chapter 1 Getting Started

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.
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

• 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.

Chapter 1 Getting Started

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.

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).

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 58) lets you configure the
WiMAX Modem’s IP address and subnet mask.
• The DHCP Client screen (Section 5.3 on page 59) to view connection
information for clients configured by the WiMAX Modem’s internal DHCP server.
• The Time Setting screen (Section 5.4 on page 60) 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

57

Chapter 5 The 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.

5.2 Set IP Address

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 66) lets you enable, disable, and
configure the DHCP server in the WiMAX Modem.
• The Static DHCP screen (Section 6.3 on page 68) lets you assign specific IP
addresses to specific computers on the LAN.
• The IP Static Route screen (Section 6.4 on page 69) lets you examine the
static routes configured in the WiMAX Modem.
• The Other Settings screen (Section 6.5 on page 71) 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 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.

User’s Guide

65

Chapter 6 The 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.

6.2 DHCP Setup
Click ADVANCED > LAN Configuration > DHCP Setup to enable, disable, and
configure the DHCP server in the WiMAX Modem.

of the subnet the WiMAX Modem is in). For example, if the IP Pool
Start Address is 10.10.10.10, the WiMAX Modem can allocate up to
10.10.10.254, or 245 IP addresses.

DNS Server
First, Second
and Third DNS
Server

Specify the IP addresses of a maximum of three DNS servers that the
network can use. The WiMAX Modem provides these IP addresses to
DHCP clients. You can specify these IP addresses two ways.
From ISP - provide the DNS servers provided by the ISP on the WAN
port.
User Defined - enter a static IP address.
DNS Relay - this setting will relay DNS information from the DNS
server obtained by the WiMAX Modem.
None - no DNS service will be provided by the WiMAX Modem.

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.

6.6 Technical Reference
The following section contains additional technical information about the WiMAX
Modem features described in this chapter.

6.6.1 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 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.

72

User’s Guide

Chapter 6 The 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 68.

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.
The LAN parameters of the WiMAX Modem 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 6.3 on page 68.

User’s Guide

73

Chapter 6 The LAN Configuration Screens

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
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.

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.

74

User’s Guide

Chapter 6 The LAN Configuration Screens
• 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.
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.
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.

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 80) lets you set up your
WiMAX Modem’s Internet settings.
• The WiMAX Configuration screen (Section 7.3 on page 82) lets set up the
frequencies used by your WiMAX Modem.
• The Antenna Selection screen (Section 7.4 on page 86) to switch between the
WiMAX Modem’s internal antenna and the external antennas (MAX-216M1R plus
only; other models do not support this option.)
• The Advanced screen (Section 7.5 on page 87) lets configure your DNS server,
RIP, Multicast and Windows Networking settings.

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

User’s Guide

77

Chapter 7 The WAN Configuration Screens
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

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.

78

User’s Guide

Chapter 7 The 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.

The NAT Configuration Screens
8.1 Overview
Use these screens to configure port forwarding and trigger ports for the WiMAX
Modem. You can also enable and disable SIP, FTP, and H.323 ALG.
Network Address Translation (NAT) maps a host’s IP address within one network
to a different IP address in another network. For example, you can use a NAT
router to map one IP address from your ISP to multiple private IP addresses for
the devices in your home network.

8.1.1 What You Can Do in This Chapter
• The General screen (Section 8.2 on page 89) lets you enable or disable NAT
and to allocate memory for NAT and firewall rules.
• The Port Forwarding screen (Section 8.3 on page 90) lets you look at the
current port-forwarding rules in the WiMAX Modem, and to enable, disable,
activate, and deactivate each one.
• The Trigger Port screen (Section 8.4 on page 94) lets you maintain trigger port
forwarding rules for the WiMAX Modem.
• The ALG screen (Section 8.5 on page 96) lets you enable and disable SIP
(VoIP), FTP (file transfer), and H.323 (audio-visual) ALG in the WiMAX Modem.

Max NAT/Firewall
Session Per User

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
be established, and users may not be able to access the Internet.
Each NAT session establishes a corresponding firewall session. Use
this field to limit the number of NAT/firewall sessions each client
computer can establish through the WiMAX Modem.
If your network has a small number of clients using peer to peer
applications, you can raise this number to ensure that their
performance is not degraded by the number of NAT sessions they
can establish. If your network has a large number of users using
peer to peer applications, you can lower this number to ensure no
single client is using all of the available NAT sessions.

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.

User’s Guide

Chapter 8 The NAT Configuration Screens
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.

Chapter 8 The NAT Configuration Screens

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.
Click ADVANCED > NAT Configuration > Trigger Port to maintain trigger port
forwarding rules for the WiMAX Modem.

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 38 Trigger Port Forwarding Example

User’s Guide

95

Chapter 8 The NAT Configuration Screens

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 unfriendly) 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.

• The Restart screen (Section 9.6 on page 107) 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.

User’s Guide

99

Chapter 9 The System Configuration Screens
• 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, 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:

100

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.

The Service Configuration
Screens
10.1 Overview
The VOICE > Service Configuration screens allow you to set up your voice
accounts and configure your QoS settings.
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.

10.1.1 What You Can Do in This Chapter
• The SIP Settings screen (Section 10.2 on page 113) lets you setup and
maintain your SIP account(s) in the WiMAX Modem.
• The Advanced SIP Settings screen (Section 10.2.1 on page 115) lets you set
up and maintain advanced settings for each SIP account
• The QoS screen (Section 10.3 on page 122) lets you set up and maintain ToS
and VLAN settings for the WiMAX Modem.

10.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.

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

User’s Guide

111

Chapter 10 The Service Configuration Screens
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.

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 SIPNumber@SIP-Service-Domain.

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).

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 “VoIPprovider.com” is the SIP service domain.

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.

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.

Use NAT
If you know the NAT router’s public IP address and SIP port number, you can use
the Use NAT feature to manually configure the WiMAX Modem to use a them in the
SIP messages. This eliminates the need for STUN or a SIP ALG. You must also
configure the NAT router to forward traffic with this port number to the WiMAX
Modem.

Chapter 10 The Service Configuration Screens

10.1.3 Before you Begin
• Ensure that you have all of your voice account information on hand. If not,
contact your voice account service provider to find out which settings in this
chapter you should configure in order to use your telephone with the WiMAX
Modem.
• Connect your WiMAX Modem to the Internet, as described in the Quick Start
Guide. If you have not already done so, then you will not be able to test your
VoIP settings.

10.2 SIP Settings
Click VOICE > Service Configuration > SIP Setting to setup and maintain
your SIP account(s) in the WiMAX Modem. Your VoIP or Internet service provider
should provide you with your account information. You can also enable and disable
each SIP account.

10.2.1 Advanced SIP Settings
This section describes the features of the Advanced SIP settings screen.

10.2.1.1 STUN
STUN (Simple Traversal of User Datagram Protocol (UDP) through Network
Address Translators) allows the WiMAX Modem to find the presence and types of
NAT routers and/or firewalls between it and the public Internet. STUN also allows
the WiMAX Modem to find the public IP address that NAT assigned, so the WiMAX
Modem can embed it in the SIP data stream. STUN does not work with symmetric
NAT routers or firewalls. See RFC 3489 for details on STUN.
The following figure shows how STUN works.
1

The WiMAX Modem (A) sends SIP packets to the STUN server (B).

2

The STUN server (B) finds the public IP address and port number that the NAT
router used on the WiMAX Modem’s SIP packets and sends them to the WiMAX
Modem.

3

The WiMAX Modem uses the public IP address and port number in the SIP packets
that it sends to the SIP server (C).

10.2.1.2 Outbound Proxy
Your VoIP service provider may host a SIP outbound proxy server to handle all of
the WiMAX Modem’s VoIP traffic. This allows the WiMAX Modem to work with any
type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off a SIP
ALG on a NAT router in front of the WiMAX Modem to keep it from re-translating
the IP address (since this is already handled by the outbound proxy server).

10.2.1.3 Voice Coding
A codec (coder/decoder) codes analog voice signals into digital signals and
decodes the digital signals back into voice signals. The WiMAX Modem supports
the following codecs.

User’s Guide

115

Chapter 10 The Service Configuration Screens
• G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures
analog signal amplitudes at regular time intervals (sampling) and converts them
into digital bits (quantization). Quantization “reads” the analog signal and then
“writes” it to the nearest digital value. For this reason, a digital sample is usually
slightly different from its analog original (this difference is known as
“quantization noise”). G.711 provides excellent sound quality but requires
64kbps of bandwidth.
• G.723 is an Adaptive Differential Pulse Code Modulation (ADPCM) waveform
codec. Differential (or Delta) PCM is similar to PCM, but encodes the audio signal
based on the difference between one sample and a prediction based on previous
samples, rather than encoding the sample’s actual quantized value. Many
thousands of samples are taken each second, and the differences between
consecutive samples are usually quite small, so this saves space and reduces
the bandwidth necessary.
However, DPCM produces a high quality signal (high signal-to-noise ratio or
SNR) for high difference signals (where the actual signal is very different from
what was predicted) but a poor quality signal (low SNR) for low difference
signals (where the actual signal is very similar to what was predicted). This is
because the level of quantization noise is the same at all signal levels. Adaptive
DPCM solves this problem by adapting the difference signal’s level of
quantization according to the audio signal’s strength. A low difference signal is
given a higher quantization level, increasing its signal-to-noise ratio. This
provides a similar sound quality at all signal levels. G.723 provides high quality
sound and requires 20 or 40 kbps.
• G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec. It uses a filter
based on information about how the human vocal tract produces sounds. The
codec analyzes the incoming voice signal and attempts to synthesize it using its
list of voice elements. It tests the synthesized signal against the original and, if
it is acceptable, transmits details of the voice elements it used to make the
synthesis. Because the codec at the receiving end has the same list, it can
exactly recreate the synthesized audio signal.G.729 provides good sound quality
and reduces the required bandwidth to 8kbps.

10.2.1.4 MWI (Message Waiting Indication)
Enable Message Waiting Indication (MWI) enables your phone to give you a
message–waiting (beeping) dial tone when you have one or more voice messages.
Your VoIP service provider must have a messaging system that sends messagewaiting-status SIP packets as defined in RFC 3842.

10.3 QoS
Network traffic can be classified by setting the ToS (Type Of Service) values at the
data source (for example, at the WiMAX Modem) so a server can decide the best
method of delivery, that is the least cost, fastest route and so on.
Virtual Local Area Network (VLAN) allows a physical network to be partitioned into
multiple logical networks. Only stations within the same group can communicate
with each other.
Your WiMAX Modem can add IEEE 802.1Q VLAN ID tags to voice frames that it
sends to the network. This allows the WiMAX Modem to communicate with a SIP
server that is a member of the same VLAN group. Some ISPs use the VLAN tag to
identify voice traffic and give it priority over other traffic.
Click VOICE > Service Configuration > QoS to set up and maintain ToS and
VLAN settings for the WiMAX Modem. QoS (Quality of Service) refers to both a
network's ability to deliver data with minimum delay and the networking methods
used to provide bandwidth for real-time multimedia applications.

A

B

1. INVITE
2. Ringing
3. OK
4. ACK

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).

User’s Guide

123

Chapter 10 The Service Configuration Screens

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.

10.4.2 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.

10.4.3 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.

10.4.4 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.

124

The client device (A in the figure) sends a call invitation to the SIP proxy server

10.4.5 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).

10.4.6 NAT and SIP
The WiMAX Modem must register its public IP address with a SIP register server.
If there is a NAT router between the WiMAX Modem and the SIP register server,
the WiMAX Modem probably has a private IP address. The WiMAX Modem 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
WiMAX Modem’s IP address from inside the SIP message and maps it to your SIP
identity. If the WiMAX Modem has a private IP address listed in the SIP message,
the SIP server cannot map it to your SIP identity. See Chapter 8 The NAT
Configuration Screens for more information.
Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to
allow the WiMAX Modem to list its public IP address in the SIP messages.

10.4.7 DiffServ
DiffServ is a class of service (CoS) model that marks packets so that they receive
specific per-hop treatment at DiffServ-compliant network devices along the route
based on the application types and traffic flow. Packets are marked with DiffServ
Code Points (DSCPs) indicating the level of service desired. This allows the
intermediary DiffServ-compliant network devices to handle the packets differently
depending on the code points without the need to negotiate paths or remember
state information for every flow. In addition, applications do not have to request a
particular service or give advanced notice of where the traffic is going.

126

User’s Guide

Chapter 10 The Service Configuration Screens

10.4.8 DSCP and Per-Hop Behavior
DiffServ defines a new DS (Differentiated Services) field to replace the Type of
Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and
a 6-bit DSCP field which can define up to 64 service levels. The following figure
illustrates the DS field.

Figure 52 DiffServ: Differentiated Service Field
DSCP

Unused

(6-bit)

(2-bit)

DSCP is backward compatible with the three precedence bits in the ToS octet so
that non-DiffServ compliant, ToS-enabled network device will not conflict with the
DSCP mapping.
The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior),
that each packet gets across the DiffServ network. Based on the marking rule,
different kinds of traffic can be marked for different priorities of forwarding.
Resources can then be allocated according to the DSCP values and the configured
policies.

Use the VOICE > Phone screens to configure the volume, echo cancellation, VAD
settings and custom tones for the phone port on the WiMAX Modem. You can also
select which SIP account to use for making outgoing calls.

11.1.1 What You Can Do in This Chapter
• The Analog Phone screen (Section 11.2 on page 130) lets you control which
SIP accounts each phone uses.
• The Common screen (Section 11.3 on page 132) lets you activate and
deactivate immediate dialing.
• The Region screen (Section 11.4 on page 133) lets you maintain settings that
often depend on the region of the world in which the WiMAX Modem is located.

11.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.

Voice Activity Detection/Silence Suppression/Comfort Noise
Voice Activity Detection (VAD) detects whether or not speech is present. This lets
the WiMAX Modem reduce the bandwidth that a call uses by not transmitting
“silent packets” when you are not speaking.
When using VAD, the WiMAX Modem generates comfort noise when the other
party is not speaking. The comfort noise lets you know that the line is still
connected as total silence could easily be mistaken for a lost connection.

Echo Cancellation
G.168 is an ITU-T standard for eliminating the echo caused by the sound of your
voice reverberating in the telephone receiver while you talk.

11.5 Technical Reference
The following section contains additional technical information about the WiMAX
Modem features described in this chapter.

11.5.1 The Flash Key
Flashing means to press the hook for a short period of time (a few hundred
milliseconds) before releasing it. On newer telephones, there should be a "flash"
key (button) that generates the signal electronically. If the flash key is not
available, you can tap (press and immediately release) the hook by hand to
achieve the same effect. However, using the flash key is preferred since the
timing is much more precise. The WiMAX Modem may interpret manual tapping as
hanging up if the duration is too long
You can invoke all the supplementary services by using the flash key.

11.5.2 Europe Type Supplementary Phone Services
This section describes how to use supplementary phone services with the Europe
Type Call Service Mode. Commands for supplementary services are listed in the
table below.
After pressing the flash key, if you do not issue the sub-command before the
default sub-command timeout (2 seconds) expires or issue an invalid subcommand, the current operation will be aborted.

The Phone Book Screens
12.1 Overview
The VOICE > Phone Book screens allow you to configure the WiMAX Modem’s
phone book for making VoIP calls.

12.1.1 What You Can Do in This Chapter
• The Incoming Call Policy screen (Section 12.2 on page 140) lets you maintain
rules for handling incoming calls. You can block, redirect, or accept them.
• The Speed Dial screen (Section 12.3 on page 142) lets you add, edit, or
remove speed-dial entries.

12.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.

Speed Dial and Peer-to-Peer Calling
Speed dial provides shortcuts for dialing frequently used (VoIP) phone numbers. It
is also required if you want to make peer-to-peer calls.
In peer-to-peer calls, you call another VoIP device directly without going through
a SIP server. In the WiMAX Modem, you must set up a speed dial entry in the
phone book in order to do this. Select Non-Proxy (Use IP or URL) in the Type
column and enter the callee’s IP address or domain name. The WiMAX Modem
sends SIP INVITE requests to the peer VoIP device when you use the speed dial
entry.
You do not need to configure a SIP account in order to make a peer-to-peer VoIP
call.

The Certificates Screens
13.1 Overview
Use the TOOLS > Certificates screens to manage public key certificates on the
WiMAX Modem.
The WiMAX Modem can use public key certificates (also sometimes called “digital
IDs”) to authenticate users. Certificates are based on public-private key pairs. A
certificate contains the certificate owner’s identity and public key. Certificates
provide a way to exchange public keys for use in authentication.
Public key certificates are used by web browsers to ensure that a secure web site
is legitimate. When a certificate authority such as VeriSign, Comodo, or Network
Solutions (to name a few) receives a certificate request from a website operator,
they confirm that the web domain and contact information in the request match
those on public record with a domain name registrar. If they match, then the
certificate is issued to the website operator, who then places it on his site to be
issued to all visiting web browsers to let them know that the site is legitimate.

13.1.1 What You Can Do in This Chapter
• The My Certificates screen (Section 13.2 on page 148) lets you generate and
export self-signed certificates or certification requests and import the WiMAX
Modem’s CA-signed certificates.
• The Trusted CAs screen (Section 13.3 on page 158) lets you display a
summary list of certificates of the certification authorities that you have set the
WiMAX Modem to accept as trusted.

13.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.

Certificate Authorities
A Certification Authority (CA) issues certificates and guarantees the identity of
each certificate owner. There are commercial certification authorities like
CyberTrust or VeriSign and government certification authorities. You can use the

The following section contains additional technical information about the WiMAX
Modem features described in this chapter.

User’s Guide

163

Chapter 13 The Certificates Screens

13.4.1 Certificate Authorities
When using public-key cryptology for authentication, each host has two keys. One
key is public and can be made openly available. The other key is private and must
be kept secure.
These keys work like a handwritten signature (in fact, certificates are often
referred to as “digital signatures”). Only you can write your signature exactly as it
ought to look. When people know what your signature ought to look like, they can
verify whether something was signed by you, or by someone else. In the same
way, your private key “writes” your digital signature and your public key allows
people to verify whether data was signed by you, or by someone else. This
process works as follows.
1

Tim wants to send a message to Jenny. He needs her to be sure that it comes
from him, and that the message content has not been altered by anyone else
along the way. Tim generates a public key pair (one public key and one private
key).

2

Tim keeps the private key and makes the public key openly available. This means
that anyone who receives a message seeming to come from Tim can read it and
verify whether it is really from him or not.

3

Tim uses his private key to sign the message and sends it to Jenny.

4

Jenny receives the message and uses Tim’s public key to verify it. Jenny knows
that the message is from Tim, and she knows that although other people may
have been able to read the message, no-one can have altered it (because they
cannot re-sign the message with Tim’s private key).

5

Additionally, Jenny uses her own private key to sign a message and Tim uses
Jenny’s public key to verify the message.
The WiMAX Modem uses certificates based on public-key cryptology to
authenticate users attempting to establish a connection, not to encrypt the data
that you send after establishing a connection. The method used to secure the data
that you send through an established connection depends on the type of
connection. For example, a VPN tunnel might use the triple DES encryption
algorithm.
The certification authority uses its private key to sign certificates. Anyone can
then use the certification authority’s public key to verify the certificates.
A certification path is the hierarchy of certification authority certificates that
validate a certificate. The WiMAX Modem does not trust a certificate if any
certificate on its path has expired or been revoked.

164

User’s Guide

Chapter 13 The Certificates Screens
Certification authorities maintain directory servers with databases of valid and
revoked certificates. A directory of certificates that have been revoked before the
scheduled expiration is called a CRL (Certificate Revocation List). The WiMAX
Modem can check a peer’s certificate against a directory server’s list of revoked
certificates. The framework of servers, software, procedures and policies that
handles keys is called PKI (public-key infrastructure).

13.4.1.1 Advantages of Certificates
Certificates offer the following benefits.
• The WiMAX Modem only has to store the certificates of the certification
authorities that you decide to trust, no matter how many devices you need to
authenticate.
• Key distribution is simple and very secure since you can freely distribute public
keys and you never need to transmit private keys.

13.4.1.2 Self-signed Certificates
You can have the WiMAX Modem act as a certification authority and sign its own
certificates.

13.4.1.3 Factory Default Certificate
The WiMAX Modem generates its own unique self-signed certificate when you first
turn it on. This certificate is referred to in the GUI as the factory default
certificate.

13.4.1.4 Certificate File Formats
Any certificate that you want to import has to be in one of these file formats:
• Binary X.509: This is an ITU-T recommendation that defines the formats for
X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses
lowercase letters, uppercase letters and numerals to convert a binary X.509
certificate into a printable form.
• Binary PKCS#7: This is a standard that defines the general syntax for data
(including digital signatures) that may be encrypted. A PKCS #7 file is used to
transfer a public key certificate. The private key is not included. The WiMAX
Modem currently allows the importation of a PKS#7 file that contains a single
certificate.
• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses
lowercase letters, uppercase letters and numerals to convert a binary PKCS#7
certificate into a printable form.

Note: Be careful to not convert a binary file to text during the transfer process. It is
easy for this to occur since many programs use text files by default.

Chapter 13 The Certificates Screens

13.4.2 Verifying a Certificate
Before you import a certificate into the WiMAX Modem, you should verify that you
have the correct certificate. This is especially true of trusted certificates since the
WiMAX Modem also trusts any valid certificate signed by any of the imported
trusted certificates.

13.4.2.1 Checking the Fingerprint of a Certificate on Your Computer
A certificate’s fingerprints are message digests calculated using the MD5 or SHA1
algorithms. The following procedure describes how to check a certificate’s
fingerprint to verify that you have the actual certificate.
1

Browse to where you have the certificate saved on your computer.

2

Make sure that the certificate has a “.cer” or “.crt” file name extension. (On some
Linux distributions, the file extension may be “.der”.)

Details tab and scroll down to the Thumbprint Algorithm and Thumbprint
fields.

Use a secure method to verify that the certificate owner has the same information
in the Thumbprint Algorithm and Thumbprint fields. The secure method may
very based on your situation. Possible examples would be over the telephone or

The Firewall Screens
14.1 Overview
Use the TOOLS > Firewall screens to manage WiMAX Modem’s firewall security
measures.
Originally, the term firewall referred to a construction technique designed to
prevent the spread of fire from one room to another. The networking term
"firewall" is a system or group of systems that enforces an access-control policy
between two networks. It may also be defined as a mechanism used to protect a
trusted network from an untrusted network. Of course, firewalls cannot solve
every security problem.
A firewall is one of the mechanisms used to establish a network security perimeter
in support of a network security policy. It should never be the only mechanism or
method employed. For a firewall to guard effectively, you must design and deploy
it appropriately. This requires integrating the firewall into a broad informationsecurity policy. In addition, specific policies must be implemented within the
firewall itself.

14.1.1 What You Can Do in This Chapter
• The Firewall Setting screen (Section 14.2 on page 170) lets you configure the
basic settings for your firewall.
• The Service Setting screen (Section 14.3 on page 173) lets you enable service
blocking, set up the date and time service blocking is effective, and to maintain
the list of services you want to block.

14.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.

About the WiMAX Modem Firewall
The WiMAX Modem firewall is a stateful inspection firewall and is designed to
protect against Denial of Service attacks when activated. The WiMAX Modem's
purpose is to allow a private Local Area Network (LAN) to be securely connected to

User’s Guide

169

Chapter 14 The Firewall Screens
the Internet. The WiMAX Modem can be used to prevent theft, destruction and
modification of data, as well as log events, which may be important to the security
of your network.
The WiMAX Modem is installed between the LAN and a WiMAX base station
connecting to the Internet. This allows it to act as a secure gateway for all data
passing between the Internet and the LAN.
The WiMAX Modem has one Ethernet (LAN) port. The LAN (Local Area Network)
port attaches to a network of computers, which needs security from the outside
world. These computers will have access to Internet services such as e-mail, FTP
and the World Wide Web. However, “inbound access” is not allowed (by default)
unless the remote host is authorized to use a specific service.

14.2 Firewall Setting
This section describes firewalls and the built-in WiMAX Modem’s firewall features.

14.2.1 Firewall Rule Directions
Figure 68 Firewall Rule Directions

LAN-to-WAN rules are local network to Internet firewall rules. The default is to
forward all traffic from your local network to the Internet.
You can block certain LAN-to-WAN traffic in the Services screen (click the
Services tab). All services displayed in the Blocked Services list box are LANto-WAN firewall rules that block those services originating from the LAN.
Blocked LAN-to-WAN packets are considered alerts. Alerts are “higher priority
logs” that include system errors, attacks and attempted access to blocked web
sites. Alerts appear in red in the View Log screen. You may choose to have alerts
e-mailed immediately in the Log Settings screen.

170

User’s Guide

Chapter 14 The Firewall Screens
LAN-to-LAN/WiMAX Modem means the LAN to the WiMAX Modem LAN interface.
This is always allowed, as this is how you manage the WiMAX Modem from your
local computer.
WAN-to-LAN rules are Internet to your local network firewall rules. The default is
to block all traffic from the Internet to your local network.
How can you forward certain WAN to LAN traffic? You may allow traffic originating
from the WAN to be forwarded to the LAN by:
• Configuring NAT port forwarding rules.
• Configuring WAN or LAN & WAN access for services in the Remote MGMT
screens or SMT menus. When you allow remote management from the WAN,
you are actually configuring WAN-to-WAN/WiMAX Modem firewall rules. WANto-WAN/WiMAX Modem firewall rules are Internet to the WiMAX Modem WAN
interface firewall rules. The default is to block all such traffic. When you decide
what WAN-to-LAN packets to log, you are in fact deciding what WAN-to-LAN
and WAN-to-WAN/WiMAX Modem packets to log.
Forwarded WAN-to-LAN packets are not considered alerts.

14.2.2 Triangle Route
When the firewall is on, your WiMAX Modem acts as a secure gateway between
your LAN and the Internet. In an ideal network topology, all incoming and
outgoing network traffic passes through the WiMAX Modem to protect your LAN
against attacks.

14.4 Technical Reference
The following section contains additional technical information about the WiMAX
Modem features described in this chapter.

14.4.1 Stateful Inspection Firewall.
Stateful inspection firewalls restrict access by screening data packets against
defined access rules. They make access control decisions based on IP address and
protocol. They also "inspect" the session data to assure the integrity of the
connection and to adapt to dynamic protocols. These firewalls generally provide
the best speed and transparency; however, they may lack the granular application
level access control or caching that some proxies support. Firewalls, of one type or
another, have become an integral part of standard security solutions for
enterprises.

174

User’s Guide

Chapter 14 The Firewall Screens

14.4.2 Guidelines For Enhancing Security With Your Firewall
1

Change the default password via web configurator.

2

Think about access control before you connect to the network in any way.

3

Limit who can access your router.

4

Don't enable any local service (such as telnet or FTP) that you don't use. Any
enabled service could present a potential security risk. A determined hacker might
be able to find creative ways to misuse the enabled services to access the firewall
or the network.

5

For local services that are enabled, protect against misuse. Protect by configuring
the services to communicate only with specific peers, and protect by configuring
rules to block packets for the services at specific interfaces.

6

Protect against IP spoofing by making sure the firewall is active.

7

Keep the firewall in a secured (locked) room.

14.4.3 The “Triangle Route” Problem
A traffic route is a path for sending or receiving data packets between two
Ethernet devices. You may have more than one connection to the Internet
(through one or more ISPs). If an alternate gateway is on the LAN (and its IP
address is in the same subnet as the WiMAX Modem’s LAN IP address), the
“triangle route” (also called asymmetrical route) problem may occur. The steps
below describe the “triangle route” problem.
1

A computer on the LAN initiates a connection by sending out a SYN packet to a
receiving server on the WAN.

2

The WiMAX Modem reroutes the SYN packet through Gateway A on the LAN to the
WAN.

3

The reply from the WAN goes directly to the computer on the LAN without going
through the WiMAX Modem.

User’s Guide

175

Chapter 14 The Firewall Screens
As a result, the WiMAX Modem resets the connection, as the connection has not
been acknowledged.

Figure 72 “Triangle Route” Problem

14.4.3.1 Solving the “Triangle Route” Problem
If you have the WiMAX Modem allow triangle route sessions, traffic from the WAN
can go directly to a LAN computer without passing through the WiMAX Modem and
its firewall protection.
Another solution is to use IP alias. IP alias allows you to partition your network
into logical sections over the same Ethernet interface. Your WiMAX Modem
supports up to three logical LAN interfaces with the WiMAX Modem being the
gateway for each logical network.
It’s like having multiple LAN networks that actually use the same physical cables
and ports. By putting your LAN and Gateway A in different subnets, all returning
network traffic must pass through the WiMAX Modem to your LAN. The following
steps describe such a scenario.

176

1

A computer on the LAN initiates a connection by sending a SYN packet to a
receiving server on the WAN.

2

The WiMAX Modem reroutes the packet to Gateway A, which is in Subnet 2.

3

The reply from the WAN goes to the WiMAX Modem.

User’s Guide

Chapter 14 The Firewall Screens

4

The WiMAX Modem then sends it to the computer on the LAN in Subnet 1.

Content Filter
15.1 Overview
Use the TOOLS > Content Filter screens to create and enforce policies that
restrict access to the Internet based on content
Internet content filtering allows you to create and enforce Internet access policies
tailored to their needs. Content filtering is the ability to block certain web features
or specific URL keywords. The WiMAX Modem can block web features such as
ActiveX controls, Java applets, cookies and disable web proxies. The WiMAX
Modem also allows you to define time periods and days during which the WiMAX
Modem performs content filtering.

The Remote Management
Screens
16.1 Overview
Use the TOOLS > Remote Management screens to control which computers can
use which services to access the WiMAX Modem on each interface.
Remote management allows you to determine which services/protocols can access
which WiMAX Modem interface (if any) from which computers.
You may manage your WiMAX Modem from a remote location via:

Table 63 Remote Management
•

Internet (WAN only)

•

ALL (LAN and WAN)

•

LAN only

•

Neither (Disable).

To disable remote management of a service, select Disable in the corresponding
Server Access field.
You may only have one remote management session running at a time. The
WiMAX Modem automatically disconnects a remote management session of lower
priority when another remote management session of higher priority starts. The
priorities for the different types of remote management sessions are as follows.
1

Telnet

2

HTTP

16.1.1 What You Can Do in This Chapter
• The WWW screen (Section 16.2 on page 185) lets you control HTTP access to
your WiMAX Modem.

16.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.

Remote Management Limitations
Remote management over LAN or WAN will not work when:
1

A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet,
FTP or Web service.

2

You have disabled that service in one of the remote management screens.

3

The IP address in the Secured Client IP field does not match the client IP
address. If it does not match, the WiMAX Modem will disconnect the session
immediately.

4

There is already another remote management session with an equal or higher
priority running. You may only have one remote management session running at
one time.

Remote Management and NAT
When NAT is enabled:
• Use the WiMAX Modem’s WAN IP address when configuring from the WAN.
• Use the WiMAX Modem’s LAN IP address when configuring from the LAN.

System Timeout
There is a default system management idle timeout of five minutes (three
hundred seconds). The WiMAX Modem automatically logs you out if the
management session remains idle for longer than this timeout period. The
management session does not time out when a statistics screen is polling. You can
change the timeout period in the Maintenance > System > General screen.

SNMP
Simple Network Management Protocol (SNMP) is a protocol used for exchanging
management information between network devices. SNMP is a member of the
TCP/IP protocol suite. Your WiMAX Modem supports SNMP agent functionality,
which allows a manager station to manage and monitor the WiMAX Modem
through the network. The WiMAX Modem supports SNMP version one (SNMPv1)
and version two (SNMPv2). The next figure illustrates an SNMP management
operation.

Note: SNMP is only available if TCP/IP is configured.

16.5 SNMP
An SNMP managed network consists of two main types of component: agents and
a manager.

Figure 79 SNMP Management Model

An agent is a management software module that resides in a managed device (the
WiMAX Modem). An agent translates the local management information from the
managed device into a form compatible with SNMP. The manager is the console
through which network administrators perform network management functions. It
executes applications that control and monitor managed devices.

User’s Guide

187

Chapter 16 The Remote Management Screens
The managed devices contain object variables/managed objects that define each
piece of information to be collected about a device. Examples of variables include
such as number of packets received, node port status etc. A Management
Information Base (MIB) is a collection of managed objects. SNMP allows a
manager and agents to communicate for the purpose of accessing these objects.
The WiMAX Modem supports MIB II that is defined in RFC-1213 and RFC-1215.
The focus of the MIBs is to let administrators collect statistical data and monitor
status and performance.
SNMP itself is a simple request/response protocol based on the manager/agent
model. The manager issues a request and the agent returns responses using the
following protocol operations:
• Get - Allows the manager to retrieve an object variable from the agent.
• GetNext - Allows the manager to retrieve the next object variable from a table
or list within an agent. In SNMPv1, when a manager wants to retrieve all
elements of a table from an agent, it initiates a Get operation, followed by a
series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.

16.5.1 SNMP Traps
The WiMAX Modem sends traps to the SNMP manager when any of the following
events occurs:

Table 67 SNMP Traps

188

TRAP #

TRAP NAME

DESCRIPTION

0

coldStart (defined in RFC1215)

A trap is sent after booting (power on).

1

warmStart (defined in RFC1215)

A trap is sent after booting (software reboot).

4

authenticationFailure (defined
in RFC-1215)

A trap is sent to the manager when receiving
any SNMP get or set requirements with the
wrong community (password).

6

whyReboot (defined in
ZYXEL-MIB)

A trap is sent with the reason of restart before
rebooting when the system is going to restart
(warm start).

6a

For intentional reboot:

A trap is sent with the message "System reboot
by user!" if reboot is done intentionally, (for
example, download new files, CI command "sys
reboot", etc.).

6b

For fatal error:

A trap is sent with the message of the fatal
code if the system reboots because of fatal
errors.

ICMP response packet is automatically returned. This allows the outside
user to know the WiMAX Modem exists. Your WiMAX Modem supports
anti-probing, which prevents the ICMP response packet from being
sent. This keeps outsiders from discovering your WiMAX Modem when
unsupported ports are probed.
If you clear this, your WiMAX Modem replies with an ICMP Port
Unreachable packet for a port probe on unused UDP ports and with a
TCP Reset packet for a port probe on unused TCP ports.

16.8 TR0-69
TR-069 is an abbreviation of “Technical Reference 069”, a protocol designed to
facilitate the remote management of Customer Premise Equipement (CPE), such
as the WiMAX Modem. It can be managed over a WAN by means of an Auto
Configuration Server (ACS). TR-069 is based on sending Remote Procedure Calls
(RPCs) between the ACS and the client device. RPCs are sent in Extensible Markup
Language (XML) format over HTTP or HTTPS.
An administrator can use an ACS to remotely set up the WiMAX Modem, modify its
settings, perform firmware upgrades, and monitor and diagnose it. In order to do
so, you must enable the TR-069 feature on your WiMAX Modem and then
configure it appropriately. (The ACS server which it will use must also be
configured by its administrator.)

Figure 83 TR-069 Example
SIP

ACS

HTTP

In this example, the WiMAX Modem receives data from at least 3 sources: A SIP
server for handling voice calls, an HTTP server for handling web services, and an
ACS, for configuring the WiMAX Modem remotely. All three servers are owned and
operated by the client’s Internet Service Provider. However, without the
configuration settings from the ACS, the WiMAX Modem cannot access the other
two servers. Once the WiMAX Modem receives its configuration settings and
implements them, it can connect to the other servers. If the settings change, it
will once again be unable to connect until it receives its updates from the ACS.
The WiMAX Modem can be configured to periodically check for updates from the
auto-configuration server so that the end user need not be worried about it.

Periodic
Inform Time

Enter a time interval that the WiMAX Modem will trigger a periodic
inform interval. This works in tandem with the Periodic Inform
Interval and is not mutually exclusive of it.
The Periodic Inform Time must be in the following format: yyyy-mmddThh:mm:ss where yyyy is a four digit year (“2009”), mm is a two
digit month (01~12), dd is a two digit day (01~28), hh is a two-digit
hour in 24-hour format (01~24), mm is a two digit minutes value (0160) and ss is a two digit seconds value (01-60).

Note: You must separate the day information from the hour
information with a “T”.
This feature gives the WiMAX Modem a baseline from which to begin
calculating when each periodic inform happens.
If the inform time is set for some point in the past, the WiMAX Modem
interpolates the inform interval forward to the current time and begins
its periodic inform at the appropriate time based on this interpolation.
If the inform time is set for some point in the future, then the WiMAX
Modem interpolates backwards to the current time and actually begins
at the appropriate time based on this interpolation.

QoS

17.1 Overview
Quality of Service (QoS) refers to both a network’s ability to deliver data with
minimum delay, and the networking methods used to control the use of
bandwidth. Without QoS, all traffic data is equally likely to be dropped when the
network is congested. This can cause a reduction in network performance and
make the network inadequate for time-critical application such as video-ondemand.

17.3 Class Setup
Use this screen to add, edit or delete QoS classifiers. A classifier groups traffic into
data flows according to specific criteria such as the source address, destination
address, source port number, destination port number or incoming interface. For
example, you can configure a classifier to select traffic from the same protocol
port (such as Telnet) to form a flow.
You can give different priorities to traffic that the WiMAX Modem forwards out
through the WAN interface. Give high priority to voice and video to make them run
more smoothly. Similarly, give low priority to many large file downloads so that
they do not reduce the quality of other applications.

The following terms and concepts may help as you read through this chapter.

Alerts
An alert is a type of log that warrants more serious attention. Some categories
such as System Errors consist of both logs and alerts.

Syslog Logs
There are two types of syslog: event logs and traffic logs.
The device generates an event log when a system event occurs, for example,
when a user logs in or the device is under attack. The device generates a traffic
log when a "session" is terminated.
A traffic log summarizes the session's type, when it started and stopped the
amount of traffic that was sent and received and so on. An external log analyzer

The router sent a TCP reset packet when a TCP
connection state was out of order.Note: The firewall
refers to RFC793 Figure 6 to check the TCP state.

Firewall session time
out, sent TCP RST

The router sent a TCP reset packet when a dynamic
firewall session timed out.
The default timeout values are as follows:
ICMP idle timeout: 3 minutes
UDP idle timeout: 3 minutes
TCP connection (three way handshaking) timeout: 270
seconds
TCP FIN-wait timeout: 2 MSL (Maximum Segment
Lifetime set in the TCP header).

TCP reset timeout: 10 seconds

Exceed MAX incomplete,
sent TCP RST

The router sent a TCP reset packet when the number of
incomplete connections (TCP and UDP) exceeded the
user-configured threshold. (Incomplete count is for all
TCP and UDP connections through the firewall.)Note:
When the number of incomplete connections (TCP + UDP)
> “Maximum Incomplete High”, the router sends TCP RST
packets for TCP connections and destroys TOS (firewall
dynamic sessions) until incomplete connections <
“Maximum Incomplete Low”.

server. Contact your VoIP service provider.

Problems With Multiple SIP Accounts

You can set up two SIP accounts on your WiMAX Modem. By default your WiMAX
Modem uses SIP account 1 for outgoing calls, and it uses SIP accounts 1 and 2 for
incoming calls. With this setting, you always use SIP account 1 for your outgoing
calls and you cannot distinguish which SIP account the calls are coming in
through. If you want to control the use of different dialing plans for accounting
purposes or other reasons, you need to configure your phone port in order to
control which SIP account you are using when placing or receiving calls.

20.5 Reset the WiMAX Modem to Its Factory

DESCRIPTION

Web-based Configuration
and Management Tool

Also known as “the web configurator”, this is a firmwarebased management solution for the WiMAX Modem. You must
connect using a compatible web browser in order to use it.

High Speed Wireless
Internet Access

The WiMAX Modem is ideal for high-speed wireless Internet
browsing.
WiMAX (Worldwide Interoperability for Microwave Access) is
a wireless networking standard providing high-bandwidth,
wide-range secured wireless service. The WiMAX Modem is a
WiMAX mobile station (MS) compatible with the IEEE 802.16e
standard.

Firewall

238

The WiMAX Modem is a stateful inspection firewall with DoS
(Denial of Service) protection. By default, when the firewall is
activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The WiMAX
Modem’s firewall supports TCP/UDP inspection, DoS detection
and prevention, real time alerts, reports and logs.

User’s Guide

Chapter 21 Product Specifications

Table 104 Firmware Specifications (continued)
FEATURE

DESCRIPTION

Content Filtering

The WiMAX Modem can block access to web sites containing
specified keywords. You can define time periods and days
during which content filtering is enabled and include or
exclude a range of users on the LAN from content filtering.

Network Address
Translation (NAT)

Network Address Translation (NAT) allows the translation of
an Internet protocol address used within one network (for
example a private IP address used in a local network) to a
different IP address known within another network (for
example a public IP address used on the Internet).

Universal Plug and Play
(UPnP)

Your device and other UPnP enabled devices can use the
standard TCP/IP protocol to dynamically join a network,
obtain an IP address and convey their capabilities to each
other.

Dynamic DNS Support

With Dynamic DNS support, you can have a static hostname
alias for a dynamic IP address, allowing the host to be more
easily accessible from various locations on the Internet. You
must register for this service with a Dynamic DNS service
provider.

DHCP

DHCP (Dynamic Host Configuration Protocol) allows the
individual clients (computers) to obtain the TCP/IP
configuration at start-up from a centralized DHCP server.
Your device has built-in DHCP server capability enabled by
default. It can assign IP addresses, an IP default gateway
and DNS servers to DHCP clients. Your device can also act as
a surrogate DHCP server (DHCP Relay) where it relays IP
address assignment from the actual real DHCP server to the
clients.

IP Alias

IP alias allows you to partition a physical network into logical
networks over the same Ethernet interface. Your device
supports three logical LAN interfaces via its single physical
Ethernet interface with the your device itself as the gateway
for each LAN network.

Multiple SIP Accounts

You can configure multiple voice (SIP) accounts.

SIP ALG

Your device is a SIP Application Layer Gateway (ALG). It
allows VoIP calls to pass through NAT for devices behind it
(such as a SIP-based VoIP software application on a
computer).

Dynamic Jitter Buffer

The built-in adaptive buffer helps to smooth out the
variations in delay (jitter) for voice traffic (up to 60 ms). This
helps ensure good voice quality for your conversations.

Voice Activity Detection/
Silence Suppression

Voice Activity Detection (VAD) reduces the bandwidth that a
call uses by not transmitting when you are not speaking.

Comfort Noise Generation

Your device generates background noise to fill moments of
silence when the other device in a call stops transmitting
because the other party is not speaking (as total silence
could easily be mistaken for a lost connection).

Echo Cancellation

You device supports G.168 of at least 24 ms.
This an ITU-T standard for eliminating the echo caused by the
sound of your voice reverberating in the telephone receiver
while you talk.

Call Park and
Pickup

Call park and pickup lets you put a call on hold (park) and then
continue the call (pickup). The caller must still pay while the call is
parked.
When you park the call, you enter a number of your choice (up to
eight digits), which you must enter again when you pick up the call. If
you do not enter the correct number, you cannot pickup the call. This
means that only someone who knows the number you have chosen
can pick up the call.
You can have more than one call on hold at the same time, but you
must give each call a different number.

User’s Guide

Call Return

With call return, you can place a call to the last number that called
you (either answered or missed). The last incoming call can be
through either SIP or PSTN.

Country Code

Phone standards and settings differ from one country to another, so
the settings on your WiMAX Modem must be configured to match
those of the country you are in. The country code feature allows you
to do this by selecting the country from a list rather than changing
each setting manually. Configure the country code feature when you
move the WiMAX Modem from one country to another.

Do not Disturb
(DnD)

This feature allows you to set your phone not to ring when someone
calls you. You can set each phone independently using its keypad, or
configure global settings for all phones using the command line
interpreter.

Auto Dial

You can set the WiMAX Modem to automatically dial a specified
number immediately whenever you lift a phone off the hook. Use the
Web Configurator to set the specified number. Use the command line
interpreter to have the WiMAX Modem wait a specified length of time
before dialing the number.

242

Phone config

The phone configuration table allows you to customize the phone
keypad combinations you use to access certain features on the
WiMAX Modem, such as call waiting, call return, call forward, etc. The
phone configuration table is configurable in command interpreter
mode.

Firmware update
enable / disable

If your service provider uses this feature, you hear a recorded
message when you pick up the phone when new firmware is available
for your WiMAX Modem. Enter *99# in your phone’s keypad to have
the WiMAX Modem upgrade the firmware, or enter #99# to not
upgrade. If your service provider gave you different numbers to use,
enter them instead. If you enter the code to not upgrade, you can
make a call as normal. You will hear the recording again each time
you pick up the phone, until you upgrade.

Call waiting

This feature allows you to hear an alert when you are already using
the phone and another person calls you. You can then either reject
the new incoming call, put your current call on hold and receive the
new incoming call, or end the current call and receive the new
incoming call.

Call forwarding

With this feature, you can set the WiMAX Modem to forward calls to a
specified number, either unconditionally (always), when your number
is busy, or when you do not answer. You can also forward incoming
calls from one specified number to another.

Caller ID

The WiMAX Modem supports caller ID, which allows you to see the
originating number of an incoming call (on a phone with a suitable
display).

REN

A Ringer Equivalence Number (REN) is used to determine the number
of devices (like telephones or fax machines) that may be connected
to the telephone line. Your device has a REN of three, so it can
support three devices per telephone port.

QoS (Quality of
Service)

Quality of Service (QoS) mechanisms help to provide better service
on a per-flow basis. Your device supports Type of Service (ToS)
tagging and Differentiated Services (DiffServ) tagging. This allows
the device to tag voice frames so they can be prioritized over the
network.

DESCRIPTION

Web-based Configuration
and Management Tool

Also known as “the web configurator”, this is a firmwarebased management solution for the WiMAX Modem. You must
connect using a compatible web browser in order to use it.

High Speed Wireless
Internet Access

The WiMAX Modem is ideal for high-speed wireless Internet
browsing.
WiMAX (Worldwide Interoperability for Microwave Access) is
a wireless networking standard providing high-bandwidth,
wide-range secured wireless service. The WiMAX Modem is a
WiMAX mobile station (MS) compatible with the IEEE 802.16e
standard.

User’s Guide

Firewall

The WiMAX Modem is a stateful inspection firewall with DoS
(Denial of Service) protection. By default, when the firewall is
activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The WiMAX
Modem’s firewall supports TCP/UDP inspection, DoS detection
and prevention, real time alerts, reports and logs.

Content Filtering

The WiMAX Modem can block access to web sites containing
specified keywords. You can define time periods and days
during which content filtering is enabled and include or
exclude a range of users on the LAN from content filtering.

Network Address
Translation (NAT)

Network Address Translation (NAT) allows the translation of
an Internet protocol address used within one network (for
example a private IP address used in a local network) to a
different IP address known within another network (for
example a public IP address used on the Internet).

Universal Plug and Play
(UPnP)

Your device and other UPnP enabled devices can use the
standard TCP/IP protocol to dynamically join a network,
obtain an IP address and convey their capabilities to each
other.

Dynamic DNS Support

With Dynamic DNS support, you can have a static hostname
alias for a dynamic IP address, allowing the host to be more
easily accessible from various locations on the Internet. You
must register for this service with a Dynamic DNS service
provider.

DHCP

DHCP (Dynamic Host Configuration Protocol) allows the
individual clients (computers) to obtain the TCP/IP
configuration at start-up from a centralized DHCP server.
Your device has built-in DHCP server capability enabled by
default. It can assign IP addresses, an IP default gateway
and DNS servers to DHCP clients. Your device can also act as
a surrogate DHCP server (DHCP Relay) where it relays IP
address assignment from the actual real DHCP server to the
clients.

IP Alias

IP alias allows you to partition a physical network into logical
networks over the same Ethernet interface. Your device
supports three logical LAN interfaces via its single physical
Ethernet interface with the your device itself as the gateway
for each LAN network.

Multiple SIP Accounts

You can configure multiple voice (SIP) accounts.

Table 112 Voice Features
Call Park and
Pickup

Call park and pickup lets you put a call on hold (park) and then
continue the call (pickup). The caller must still pay while the call is
parked.
When you park the call, you enter a number of your choice (up to
eight digits), which you must enter again when you pick up the call. If
you do not enter the correct number, you cannot pickup the call. This
means that only someone who knows the number you have chosen
can pick up the call.
You can have more than one call on hold at the same time, but you
must give each call a different number.

248

Call Return

With call return, you can place a call to the last number that called
you (either answered or missed). The last incoming call can be
through either SIP or PSTN.

Country Code

Phone standards and settings differ from one country to another, so
the settings on your WiMAX Modem must be configured to match
those of the country you are in. The country code feature allows you
to do this by selecting the country from a list rather than changing
each setting manually. Configure the country code feature when you
move the WiMAX Modem from one country to another.

Do not Disturb
(DnD)

This feature allows you to set your phone not to ring when someone
calls you. You can set each phone independently using its keypad, or
configure global settings for all phones using the command line
interpreter.

Auto Dial

You can set the WiMAX Modem to automatically dial a specified
number immediately whenever you lift a phone off the hook. Use the
Web Configurator to set the specified number. Use the command line
interpreter to have the WiMAX Modem wait a specified length of time
before dialing the number.

Phone config

The phone config table allows you to customize the phone keypad
combinations you use to access certain features on the WiMAX
Modem, such as call waiting, call return, call forward, etc. The phone
config table is configurable in command interpreter mode.

Firmware update
enable / disable

If your service provider uses this feature, you hear a recorded
message when you pick up the phone when new firmware is available
for your WiMAX Modem. Enter *99# in your phone’s keypad to have
the WiMAX Modem upgrade the firmware, or enter #99# to not
upgrade. If your service provider gave you different numbers to use,
enter them instead. If you enter the code to not upgrade, you can
make a call as normal. You will hear the recording again each time
you pick up the phone, until you upgrade.

Call waiting

This feature allows you to hear an alert when you are already using
the phone and another person calls you. You can then either reject
the new incoming call, put your current call on hold and receive the
new incoming call, or end the current call and receive the new
incoming call.

Call forwarding

With this feature, you can set the WiMAX Modem to forward calls to a
specified number, either unconditionally (always), when your number
is busy, or when you do not answer. You can also forward incoming
calls from one specified number to another.

Caller ID

The WiMAX Modem supports caller ID, which allows you to see the
originating number of an incoming call (on a phone with a suitable
display).

REN

A Ringer Equivalence Number (REN) is used to determine the number
of devices (like telephones or fax machines) that may be connected
to the telephone line. Your device has a REN of three, so it can
support three devices per telephone port.

QoS (Quality of
Service)

Quality of Service (QoS) mechanisms help to provide better service
on a per-flow basis. Your device supports Type of Service (ToS)
tagging and Differentiated Services (DiffServ) tagging. This allows
the device to tag voice frames so they can be prioritized over the
network.

A

WiMAX Security
Wireless security is vital to protect your wireless communications. Without it,
information transmitted over the wireless network would be accessible to any
networking device within range.

User Authentication and Data Encryption
The WiMAX (IEEE 802.16) standard employs user authentication and encryption to
ensure secured communication at all times.
User authentication is the process of confirming a user’s identity and level of
authorization. Data encryption is the process of encoding information so that it
cannot be read by anyone who does not know the code.
WiMAX uses PKMv2 (Privacy Key Management version 2) for authentication, and
CCMP (Counter Mode with Cipher Block Chaining Message Authentication Protocol)
for data encryption.
WiMAX supports EAP (Extensible Authentication Protocol, RFC 2486) which allows
additional authentication methods to be deployed with no changes to the base
station or the mobile or subscriber stations.

PKMv2
PKMv2 is a procedure that allows authentication of a mobile or subscriber station
and negotiation of a public key to encrypt traffic between the MS/SS and the base
station. PKMv2 uses standard EAP methods such as Transport Layer Security
(EAP-TLS) or Tunneled TLS (EAP-TTLS) for secure communication.
In cryptography, a ‘key’ is a piece of information, typically a string of random
numbers and letters, that can be used to ‘lock’ (encrypt) or ‘unlock’ (decrypt) a
message. Public key encryption uses key pairs, which consist of a public (freely
available) key and a private (secret) key. The public key is used for encryption
and the private key is used for decryption. You can decrypt a message only if you
have the private key. Public key certificates (or ‘digital IDs’) allow users to verify
each other’s identity.

User’s Guide

257

Appendix A WiMAX Security

RADIUS
RADIUS is based on a client-server model that supports authentication,
authorization and accounting. The base station is the client and the server is the
RADIUS server. The RADIUS server handles the following tasks:
• Authentication
Determines the identity of the users.
• Authorization
Determines the network services available to authenticated users once they are
connected to the network.
• Accounting
Keeps track of the client’s network activity.
RADIUS is a simple package exchange in which your base station acts as a
message relay between the MS/SS and the network RADIUS server.

Types of RADIUS Messages
The following types of RADIUS messages are exchanged between the base station
and the RADIUS server for user authentication:
• Access-Request
Sent by an base station requesting authentication.
• Access-Reject
Sent by a RADIUS server rejecting access.
• Access-Accept
Sent by a RADIUS server allowing access.
• Access-Challenge
Sent by a RADIUS server requesting more information in order to allow access.
The base station sends a proper response from the user and then sends another
Access-Request message.
The following types of RADIUS messages are exchanged between the base station
and the RADIUS server for user accounting:
• Accounting-Request
Sent by the base station requesting accounting.
• Accounting-Response
Sent by the RADIUS server to indicate that it has started or stopped accounting.
In order to ensure network security, the access point and the RADIUS server use a
shared secret key, which is a password they both know. The key is not sent over

258

User’s Guide

Appendix A WiMAX Security
the network. In addition to the shared key, password information exchanged is
also encrypted to protect the network from unauthorized access.

Diameter
Diameter (RFC 3588) is a type of AAA server that provides several improvements
over RADIUS in efficiency, security, and support for roaming.

Security Association
The set of information about user authentication and data encryption between two
computers is known as a security association (SA). In a WiMAX network, the
process of security association has three stages.
• Authorization request and reply
The MS/SS presents its public certificate to the base station. The base station
verifies the certificate and sends an authentication key (AK) to the MS/SS.
• Key request and reply
The MS/SS requests a transport encryption key (TEK) which the base station
generates and encrypts using the authentication key.
• Encrypted traffic
The MS/SS decrypts the TEK (using the authentication key). Both stations can
now securely encrypt and decrypt the data flow.

CCMP
All traffic in a WiMAX network is encrypted using CCMP (Counter Mode with Cipher
Block Chaining Message Authentication Protocol). CCMP is based on the 128-bit
Advanced Encryption Standard (AES) algorithm.
‘Counter mode’ refers to the encryption of each block of plain text with an
arbitrary number, known as the counter. This number changes each time a block
of plain text is encrypted. Counter mode avoids the security weakness of repeated
identical blocks of encrypted text that makes encrypted data vulnerable to
pattern-spotting.
‘Cipher Block Chaining Message Authentication’ (also known as CBC-MAC) ensures
message integrity by encrypting each block of plain text in such a way that its
encryption is dependent on the block before it. This series of ‘chained’ blocks
creates a message authentication code (MAC or CMAC) that ensures the encrypted
data has not been tampered with.

User’s Guide

259

Appendix A WiMAX Security

Authentication
The WiMAX Modem supports EAP-TTLS authentication.

EAP-TTLS (Tunneled Transport Layer Service)
EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for
only the server-side authentications to establish a secure connection (with EAPTLS digital certifications are needed by both the server and the wireless clients for
mutual authentication). Client authentication is then done by sending username
and password through the secure connection, thus client identity is protected. For
client authentication, EAP-TTLS supports EAP methods and legacy authentication
methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2.

IP Addresses and Subnetting
This appendix introduces IP addresses and subnet masks.
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 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.

Introduction to IP Addresses
One part of the IP address is the network number, and the other part is the host
ID. In the same way that houses on a street share a common street name, the
hosts on a network share a common network number. Similarly, as each house
has its own house number, each host on the network has its own unique
identifying number - the host ID. Routers use the network number to send
packets to the correct network, while the host ID determines to which host on the
network the packets are delivered.

Structure
An IP address is made up of four parts, written in dotted decimal notation (for
example, 192.168.1.1). Each of these four parts is known as an octet. An octet is
an eight-digit binary number (for example 11000000, which is 192 in decimal
notation).
Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or
0 to 255 in decimal.

User’s Guide

299

Appendix D IP Addresses and Subnetting
The following figure shows an example IP address in which the first three octets
(192.168.1) are the network number, and the fourth octet (16) is the host ID.

Figure 144 Network Number and Host ID

How much of the IP address is the network number and how much is the host ID
varies according to the subnet mask.

Subnet Masks
A subnet mask is used to determine which bits are part of the network number,
and which bits are part of the host ID (using a logical AND operation). The term
“subnet” is short for “sub-network”.
A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the
corresponding bit in the IP address is part of the network number. If a bit in the
subnet mask is “0” then the corresponding bit in the IP address is part of the host
ID.
The following example shows a subnet mask identifying the network number (in
bold text) and host ID of an IP address (192.168.1.2 in decimal).

Appendix D IP Addresses and Subnetting
By convention, subnet masks always consist of a continuous sequence of ones
beginning from the leftmost bit of the mask, followed by a continuous sequence of
zeros, for a total number of 32 bits.
Subnet masks can be referred to by the size of the network number part (the bits
with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the
mask are ones and the remaining 24 bits are zeroes.
Subnet masks are expressed in dotted decimal notation just like IP addresses. The
following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit
and 29-bit subnet masks.

Network Size
The size of the network number determines the maximum number of possible
hosts you can have on your network. The larger the number of network number
bits, the smaller the number of remaining host ID bits.
An IP address with host IDs of all zeros is the IP address of the network
(192.168.1.0 with a 24-bit subnet mask, for example). An IP address with host
IDs of all ones is the broadcast address for that network (192.168.1.255 with a
24-bit subnet mask, for example).
As these two IP addresses cannot be used for individual hosts, calculate the
maximum number of possible hosts in a network as follows:

Appendix D IP Addresses and Subnetting

Notation
Since the mask is always a continuous number of ones beginning from the left,
followed by a continuous number of zeros for the remainder of the 32 bit mask,
you can simply specify the number of ones instead of writing the value of each
octet. This is usually specified by writing a “/” followed by the number of bits in
the mask after the address.
For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask
255.255.255.128.
The following table shows some possible subnet masks using both notations.

Subnetting
You can use subnetting to divide one network into multiple sub-networks. In the
following example a network administrator creates two sub-networks to isolate a
group of servers from the rest of the company network for security reasons.
In this example, the company network address is 192.168.1.0. The first three
octets of the address (192.168.1) are the network number, and the remaining
octet is the host ID, allowing a maximum of 28 – 2 or 254 possible hosts.

302

User’s Guide

Appendix D IP Addresses and Subnetting
The following figure shows the company network before subnetting.

Figure 145 Subnetting Example: Before Subnetting

You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into
two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or
/25).
The “borrowed” host ID bit can have a value of either 0 or 1, allowing two
subnets; 192.168.1.0 /25 and 192.168.1.128 /25.

User’s Guide

303

Appendix D IP Addresses and Subnetting
The following figure shows the company network after subnetting. There are now
two sub-networks, A and B.

Figure 146 Subnetting Example: After Subnetting

In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of
27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself,
all ones is the subnet’s broadcast address).
192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127
with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP
address that can be assigned to an actual host for subnet A is 192.168.1.1 and
the highest is 192.168.1.126.
Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.

Example: Four Subnets
The previous example illustrated using a 25-bit subnet mask to divide a 24-bit
address into two subnets. Similarly, to divide a 24-bit address into four subnets,
you need to “borrow” two host ID bits to give four possible combinations (00, 01,
10 and 11). The subnet mask is 26 bits
(11111111.11111111.11111111.11000000) or 255.255.255.192.

304

User’s Guide

Appendix D IP Addresses and Subnetting
Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a
host ID of all zeroes is the subnet itself, all ones is the subnet’s broadcast
address).

Configuring IP Addresses
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. 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. You must
also enable Network Address Translation (NAT) on the WiMAX Modem.
Once you have decided on the network number, pick an IP address for your
WiMAX Modem that is easy to remember (for instance, 192.168.1.1) 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

User’s Guide

307

Appendix D IP Addresses and Subnetting
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.

Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are
isolated from the Internet (running only between two branch offices, for example)
you can assign any IP addresses to the hosts without problems. However, the
Internet Assigned Numbers Authority (IANA) has reserved the following three
blocks of IP addresses specifically for private networks:
• 10.0.0.0
• 172.16.0.0

— 10.255.255.255
— 172.31.255.255

• 192.168.0.0 — 192.168.255.255
You can obtain your IP address from the IANA, from an ISP, or it can be assigned
from a private network. If you belong to a small organization and your Internet
access is through an ISP, the ISP can provide you with the Internet addresses for
your local networks. On the other hand, if you are part of a much larger
organization, you should consult your network administrator for the appropriate IP
addresses.
Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment,
please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466,
Guidelines for Management of IP Address Space.

IP Address Conflicts
Each device on a network must have a unique IP address. Devices with duplicate
IP addresses on the same network will not be able to access the Internet or other
resources. The devices may also be unreachable through the network.

Conflicting Computer IP Addresses Example
More than one device can not use the same IP address. In the following example
computer A has a static (or fixed) IP address that is the same as the IP address
that a DHCP server assigns to computer B which is a DHCP client. Neither can
access the Internet. This problem can be solved by assigning a different static IP

address to computer A or setting computer A to obtain an IP address
automatically.

Figure 147 Conflicting Computer IP Addresses Example

Conflicting Router IP Addresses Example
Since a router connects different networks, it must have interfaces using different
network numbers. For example, if a router is set between a LAN and the Internet
(WAN), the router’s LAN and WAN addresses must be on different subnets. In the
following example, the LAN and WAN are on the same subnet. The LAN computers
cannot access the Internet because the router cannot route between networks.

Figure 148 Conflicting Computer IP Addresses Example

Conflicting Computer and Router IP Addresses Example
More than one device can not use the same IP address. In the following example,
the computer and the router’s LAN port both use 192.168.1.1 as the IP address.

Importing Certificates
This appendix shows you how to import public key certificates into your web
browser.
Public key certificates are used by web browsers to ensure that a secure web site
is legitimate. When a certificate authority such as VeriSign, Comodo, or Network
Solutions, to name a few, receives a certificate request from a website operator,
they confirm that the web domain and contact information in the request match
those on public record with a domain name registrar. If they match, then the
certificate is issued to the website operator, who then places it on the site to be
issued to all visiting web browsers to let them know that the site is legitimate.
Many ZyXEL products, such as the NSA-2401, issue their own public key
certificates. These can be used by web browsers on a LAN or WAN to verify that
they are in fact connecting to the legitimate device and not one masquerading as
it. However, because the certificates were not issued by one of the several
organizations officially recognized by the most common web browsers, you will
need to import the ZyXEL-created certificate into your web browser and flag that
certificate as a trusted authority.

Note: You can see if you are browsing on a secure website if the URL in your web
browser’s address bar begins with https:// or there is a sealed padlock
icon (
) somewhere in the main browser window (not all browsers show the
padlock in the same location.)

SIP Passthrough
Enabling/Disabling the SIP ALG
You can turn off the WiMAX Modem SIP ALG to avoid retranslating the IP address
of an existing SIP device that is using STUN. If you want to use STUN with a SIP
client device (a SIP phone or IP phone for example) behind the WiMAX Modem,
use the ip alg disable ALG_SIP command to turn off the SIP ALG.

Signaling Session Timeout
Most SIP clients have an “expire” mechanism indicating the lifetime of signaling
sessions. The SIP UA sends registration packets to the SIP server periodically and
keeps the session alive in the WiMAX Modem.
If the SIP client does not have this mechanism and makes no call during the
WiMAX Modem SIP timeout default (60 minutes), the WiMAX Modem SIP ALG
drops any incoming calls after the timeout period. You can use the ip alg
siptimeout command to change the timeout value.

Audio Session Timeout
If no voice packets go through the SIP ALG before the timeout period default (5
minutes) expires, the SIP ALG does not drop the call but blocks all voice traffic
and deletes the audio session. You cannot hear anything and you will need to
make a new call to continue your conversation.
