All graphics and Web Configurator screens shown in this book are based on the
MAX-206M1R unless otherwise noted.
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.

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.

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

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
Chapter 5 The Setup Screens
User’s Guide
58
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

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.
Chapter 6 The LAN Configuration Screens
User’s Guide
66
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.

LABEL DESCRIPTION
Route Name Enter the name of the static route.
Active Select this if you want the static route to be used. Clear this if you do
not want the static route to be used.
Private Select this if you do not want the WiMAX Modem to tell other routers
about this static route. For example, you might select this if the static
route is in your LAN. Clear this if you want the WiMAX Modem to tell
other routers about this static route.
Destination IP
Address Enter one of the destination IP addresses that this static route affects.
IP Subnet Mask Enter the subnet mask that defines the range of destination IP
addresses that this static route affects. If this static route affects only
one IP address, enter 255.255.255.255.
Gateway IP
Address Enter the IP address of the gateway to which the WiMAX Modem should
send packets for the specified Destination. The gateway is a router or
a switch on the same network segment as the device's LAN or WAN
port. The gateway helps forward packets to their destinations.
Metric Usually, you should keep the default value. This field is related to RIP.
The metric represents the "cost of transmission". A router determines
the best route for transmission by choosing a path with the lowest
"cost". The smaller the metric, the lower the "cost". RIP uses hop count
as the measurement of cost, where 1 is for a directly-connected
network. The metric must be 1-15; if you use a value higher than 15,
the routers assume the link is down.

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.
Multicast You do not have to enable multicasting to use RIP-2M. (See RIP
Version.)
Select which version of IGMP the WiMAX Modem uses to support
multicasting on the LAN. Multicasting sends packets to some computers
on the LAN and is an alternative to unicasting (sending packets to one
computer) and broadcasting (sending packets to every computer).
•None - The WiMAX Modem does not support multicasting.
•IGMP-v1 - The WiMAX Modem supports IGMP version 1.
•IGMP-v2 - The WiMAX Modem supports IGMP version 2.
Multicasting can improve overall network performance. However, it
requires extra processing and generates more network traffic. In
addition, other computers on the LAN have to support the same version
of IGMP.

Table 18 ADVANCED > LAN Configuration > Other Settings (continued)
LABEL DESCRIPTION
Chapter 6 The LAN Configuration Screens
User’s Guide 73
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.
Chapter 6 The LAN Configuration Screens
User’s Guide
74
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.
Chapter 6 The LAN Configuration Screens
User’s Guide 75
•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

•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
Chapter 7 The WAN Configuration Screens
User’s Guide
78
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.
Chapter 7 The WAN Configuration Screens
User’s Guide 79
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.

The following table describes the labels in this screen.
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.

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.

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.

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.

forwarding rules for the WiMAX Modem.

1Jane requests a file from the Real Audio server (port 7070).
2Port 7070 is a “trigger” port and causes the WiMAX Modem to record Jane’s
computer IP address. The WiMAX Modem associates Jane's computer IP address
with the "incoming" port range of 6970-7170.
3The Real Audio server responds using a port number ranging between 6970-7170.
4The WiMAX Modem forwards the traffic to Jane’s computer IP address.
5Only Jane can connect to the Real Audio server until the connection is closed or
times out. The WiMAX Modem times out in three minutes with UDP (User
Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet
Protocol).
Two points to remember about trigger ports:
1Trigger events only happen on data that is coming from inside the WiMAX Modem
and going to the outside.
2If an application needs a continuous data stream, that port (range) will be tied up
so that another computer on the LAN can’t trigger it.
8.5 ALG
Some applications, such as SIP, cannot operate through NAT (are NAT un-
friendly) because they embed IP addresses and port numbers in their packets’
data payload.
Some NAT routers may include a SIP Application Layer Gateway (ALG). An
Application Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323
or FTP) at the application layer.
A SIP ALG allows SIP calls to pass through NAT by examining and translating IP
addresses embedded in the data stream.

change the system mode, change the password, configure the DDNS server
settings, and set the current date and time.
9.1.1 What You Can Do in This Chapter
•The General screen (Section 9.2 on page 101) lets you change the WiMAX
Modem’s mode, set up its system name, domain name, idle timeout, and
administrator password.
•The Dynamic DNS screen (Section 9.3 on page 102) lets you set up the WiMAX
Modem as a dynamic DNS client.
•The Firmware screen (Section 9.4 on page 104) lets you upload new firmware
to the WiMAX Modem.
•The Configuration screen (Section 9.5 on page 106) lets you back up or
restore the configuration of the WiMAX Modem.
•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 double-
click the System icon. Select the Network Identification tab and then click
the Properties button. Note the entry for the Computer Name field and enter
it as the System Name.
Chapter 9 The System Configuration Screens
User’s Guide
100
• 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:
1The 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.
2If the ISP did not give you DNS server information, leave the DNS Server fields in
the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the
DNS server IP addresses.

Domain Name Enter the domain name entry that is propagated to DHCP clients on the
LAN. If you leave this blank, the domain name obtained from the ISP is
used. Use up to 38 alphanumeric characters. Spaces are not allowed,
but dashes “-” and periods "." are accepted.

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, CU-
SeeMe, 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.

CHAPTER 10
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
Chapter 10 The Service Configuration Screens
User’s Guide
112
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 SIP-
Number@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 “VoIP-
provider.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
User’s Guide 113
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.
1The WiMAX Modem (A) sends SIP packets to the STUN server (B).
2The 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.
3The WiMAX Modem uses the public IP address and port number in the SIP packets
that it sends to the SIP server (C).
Figure 46 STUN Example
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.

•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 message-
waiting-status SIP packets as defined in RFC 3842.

G.711 provides high voice quality but requires more bandwidth (64
kbps).
•G.711A is typically used in Europe.
•G.711u is typically used in North America and Japan.
•G.723 provides good voice quality, and requires 20 or 40 kbps.
•G.729 requires only 8 kbps.
The WiMAX Modem must use the same codec as the peer. When two
SIP devices start a SIP session, they must agree on a codec.
For more on voice compression, see Voice Coding on page 115
DTMF Mode Control how the WiMAX Modem handles the tones that your telephone
makes when you push its buttons. You should use the same mode your
VoIP service provider uses.
•RFC 2833 - send the DTMF tones in RTP packets
•PCM - send the DTMF tones in the voice data stream. This method
works best when you are using a codec that does not use
compression (like G.711). Codecs that use compression (like G.729)
can distort the tones.

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.

The following section contains additional technical information about the WiMAX
Modem features described in this chapter.
10.4.1 SIP Call Progression
The following figure displays the basic steps in the setup and tear down of a SIP
call. A calls B.
1A sends a SIP INVITE request to B. This message is an invitation for B to
participate in a SIP telephone call.
2B sends a response indicating that the telephone is ringing.
3B sends an OK response after the call is answered.
4A then sends an ACK message to acknowledge that B has answered the call.
5Now A and B exchange voice media (talk).
Voice VLAN ID Select this if the WiMAX Modem has to be a member of a VLAN to
communicate with the SIP server. Ask your network administrator, if
you are not sure. Enter the VLAN ID provided by your network
administrator in the field on the right. Your LAN and gateway must be
configured to use VLAN tags.
Otherwise, clear this field.

6After talking, A hangs up and sends a BYE request.
7B 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.
Figure 49 SIP User Agent
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.
1The client device (A in the figure) sends a call invitation to the SIP proxy server
(B).
AB
Chapter 10 The Service Configuration Screens
User’s Guide 125
2The SIP proxy server forwards the call invitation to C.
Figure 50 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.
1Client device A sends a call invitation for C to the SIP redirect server (B).
2The SIP redirect server sends the invitation back to A with C’s IP address (or
domain name).

Figure 51 SIP Redirect Server
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.

Chapter 10 The Service Configuration Screens
User’s Guide 127
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 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.

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.

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.

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.

CHAPTER 13
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

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.
1Tim 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).
2Tim 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.
3Tim uses his private key to sign the message and sends it to Jenny.
4Jenny 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).
5Additionally, 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.
Chapter 13 The Certificates Screens
User’s Guide 165
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
User’s Guide
166
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.
1Browse to where you have the certificate saved on your computer.
2Make sure that the certificate has a “.cer” or “.crt” file name extension. (On some
Linux distributions, the file extension may be “.der”.)

CHAPTER 14
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 information-
security 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
Chapter 14 The Firewall Screens
User’s Guide
170
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 LAN-
to-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.
Chapter 14 The Firewall Screens
User’s Guide 171
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. WAN-
to-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.
Blocked
Services This is a list of services (ports) that are inaccessible to computers on
your LAN when service blocking is effective. To remove a service from
this list, select the service, and click Delete.

14.4.2 Guidelines For Enhancing Security With Your Firewall
1Change the default password via web configurator.
2Think about access control before you connect to the network in any way.
3Limit who can access your router.
4Don'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.
5For 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.
6Protect against IP spoofing by making sure the firewall is active.
7Keep 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.
1A computer on the LAN initiates a connection by sending out a SYN packet to a
receiving server on the WAN.
2The WiMAX Modem reroutes the SYN packet through Gateway A on the LAN to the
WAN.
3The reply from the WAN goes directly to the computer on the LAN without going
through the WiMAX Modem.
Chapter 14 The Firewall Screens
User’s Guide
176
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.
1A computer on the LAN initiates a connection by sending a SYN packet to a
receiving server on the WAN.
2The WiMAX Modem reroutes the packet to Gateway A, which is in Subnet 2.
3The reply from the WAN goes to the WiMAX Modem.
Chapter 14 The Firewall Screens

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 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:
1A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet,
FTP or Web service.
2You have disabled that service in one of the remote management screens.
3The 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.
4There 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.

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
TRAP # TRAP NAME DESCRIPTION
0coldStart (defined in RFC-
1215)A trap is sent after booting (power on).
1warmStart (defined in RFC-
1215)A trap is sent after booting (software reboot).
4authenticationFailure (defined
in RFC-1215)A trap is sent to the manager when receiving
any SNMP get or set requirements with the
wrong community (password).
6whyReboot (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.

Select this to prevent outsiders from discovering your WiMAX Modem by
sending requests to unsupported port numbers. If an outside user
attempts to probe an unsupported port on your WiMAX Modem, an
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
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-mm-
ddThh: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 (01-
60) 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-on-
demand.

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 Logs Screens
18.1 Overview
Use the TOOLS > Logs screens to look at log entries and alerts and to configure
the WiMAX Modem’s log and alert settings.
For a list of log messages, see Section 18.4 on page 205.
18.1.1 What You Can Do in This Chapter
•The View Logs screen (Section 18.2 on page 201) lets you look at log entries
and alerts.
•The Log Settings screen (Section 18.3 on page 203) lets you configure where
the WiMAX Modem sends logs and alerts, the schedule for sending logs, and
which logs and alerts are sent or recorded.
18.1.2 What You Need to Know
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
Chapter 18 The Logs Screens
User’s Guide
200
can reconstruct and analyze the traffic flowing through the device after collecting
the traffic logs.
The following table shows RFC-2408 ISAKMP payload types that the log displays.
Please refer to the RFC for detailed information on each type.
Table 75 Syslog Logs
LOG MESSAGE DESCRIPTION

This message is sent by the system ("RAS" displays
as the system name if you haven’t configured one)
when the router generates a syslog. The facility is
defined in the Log Settings screen. The severity is
the log’s syslog class. The definition of messages
and notes are defined in the various log charts
throughout this appendix. The “devID” is the MAC
address of the router’s LAN port. The “cat” is the
same as the category in the router’s logs.
Traffic Log: <Facility*8 +
Severity>Mon dd hr:mm:ss
hostname src="<srcIP:srcPort>"
