CHAPTER 1
Getting Started
1.1 About Your MAX-207HW2R
The MAX-207HW2R 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 MAX-
207HW2R’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 20 on page 173 for a complete list of features for your model.
1.1.1 WiMAX Internet Access
Connect your computer or network to the MAX-207HW2R for WiMAX Internet
access. See the Quick Start Guide for instructions on hardware connection.
In a wireless metropolitan area network (MAN), the MAX-207HW2R connects to a
WiMAX base station (BS) for Internet access.
The following diagram shows a notebook computer equipped with the MAX-
207HW2R 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.
Chapter 1 Getting Started
MAX-207HW2R User’s Guide
20
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 MAX-207HW2R to make
and receive the following types of VoIP telephone calls:
• Peer-to-Peer calls - Use the MAX-207HW2R to make a call directly to the
recipient’s IP address without using a SIP proxy server.
Figure 2 MAX-207HW2R’s VoIP Features - Peer-to-Peer Calls
• Calls via a VoIP service provider - The MAX-207HW2R 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 MAX-
207HW2R
Do the following things regularly to make the MAX-207HW2R more secure and to
manage the MAX-207HW2R 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 MAX-207HW2R
becomes unstable or even crashes. If you forget your password, you will have to
reset the MAX-207HW2R to its factory default settings. If you backed up an
earlier configuration file, you would not have to totally re-configure the MAX-
207HW2R. You could simply restore your last configuration.
Signal

CHAPTER 3
The Setup Screens
3.1 Overview
Use these screens to configure or view LAN, DHCP Client and WAN settings.
3.1.1 What You Can Do in This Chapter
•The LAN Configuration screen (Section 3.2 on page 32) lets you configure the
MAX-207HW2R’s IP address and subnet mask.
•The DHCP Client screen (Section 3.3 on page 33) lets you view all DHCP client
information.
•The Time Setting screen (Section 3.4 on page 35) lets you configure your
MAX-207HW2R’s time and date keeping settings.
3.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
LAN
A Local Area Network, or a shared communication system to which many
computers are attached. A LAN, as its name implies, is limited to a local area such
as a home or office environment. LANs have different topologies, the most
common being the linear bus and the star configuration.
IP Address
IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to
communicate across the network. These networking devices are also known as
hosts.
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your
device will compute the subnet mask automatically based on the IP Address that
Chapter 3 The Setup Screens
MAX-207HW2R User’s Guide
32
you entered. You do not need to change the computer subnet mask unless you are
instructed to do so.
DHCP
Your WiMAX Modem can act as a DHCP (Dynamic Host Configuration Protocol)
server that can assign your LAN computers an IP address, subnet mask, DNS and
other routing information when its LAN DHCP feature is turned on.
Daytime
A network protocol used by devices for debugging and time measurement. A
computer can use this protocol to set its internal clock but only if it knows in which
order the year, month, and day are returned by the server. Not all servers use the
same format.
Time
A network protocol for retrieving the current time from a server. The computer
issuing the command compares the time on its clock to the information returned
by the server, adjusts itself automatically for time zone differences, then
calculates the difference and corrects itself if there has been any temporal drift.
NTP
NTP stands for Network Time Protocol. It is employed by devices connected to the
Internet in order to obtain a precise time setting from an official time server.
These time servers are accurate to within 200 microseconds.
3.1.3 Before You Begin
• Make sure that you have made all the appropriate hardware connections to the
MAX-207HW2R, 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.

3.4.1 Pre-Defined NTP Time Servers List
The MAX-207HW2R uses a pre-defined list of NTP time servers if you do not
specify a time server or it cannot synchronize with the time server you specified.
It can use this list regardless of the time protocol you select.
When the MAX-207HW2R uses the list, it randomly selects one server and tries to
synchronize with it. If the synchronization fails, then it goes through the rest of
the list in order until either it is successful or all the pre-defined NTP time servers
have been tried.
Time Protocol Select the time service protocol that your time server
uses.Check with your ISP or network administrator, or use trial-
and-error to find a protocol that works.
Daytime (RFC 867) - This format is day/month/year/time
zone.
Time (RFC 868) - This format displays a 4-byte integer giving
the total number of seconds since 1970/1/1 at 0:0:0.
NTP (RFC 1305) - This format is similar to Time (RFC 868).

•The DHCP Setup screen (Section 5.2 on page 44) lets you enable, disable, and
configure the DHCP server in the MAX-207HW2R.
•The Static DHCP screen (Section 5.3 on page 45) lets you assign specific IP
addresses to specific computers on the LAN.
•The IP Alias screen (Section 5.4 on page 47) lets you add subnets on the LAN
port. You can also control what routing information is sent and received by each
subnet.
•The Advanced screen (Section 5.5 on page 49) lets you control the routing
information that is sent and received by each subnet assign specific IP
addresses to specific computers on the LAN.
5.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
IP Address
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 5 The LAN Configuration Screens
MAX-207HW2R User’s Guide

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 MAX-
207HW2R an IP address, subnet mask, DNS and other routing information when
it’s turned on.

5.6 Technical Reference
The following section contains additional technical information about the MAX-
207HW2R features described in this chapter.
5.6.1 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 MAX-207HW2R. 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 192.168.100.1 to 192.168.1.254 (zero and 255 are
reserved). In other words, the first three numbers specify the network number
while the last number identifies an individual computer on that network.
Multicast You do not have to enable multicasting to use RIP-2M. (See RIP
Version.)
Select which version of IGMP the MAX-207HW2R 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 MAX-207HW2R does not support multicasting.
•IGMP-v1 - The MAX-207HW2R supports IGMP version 1.
•IGMP-v2 - The MAX-207HW2R 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.

LABEL DESCRIPTION
Chapter 5 The LAN Configuration Screens
MAX-207HW2R User’s Guide 51
Once you have decided on the network number, pick an IP address that is easy to
remember, for instance, 192.168.100.1, for your MAX-207HW2R, 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
MAX-207HW2R 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 MAX-207HW2R unless you are instructed to do otherwise.
5.6.2 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 MAX-207HW2R as a DHCP server or disable it. When configured as a
server, the MAX-207HW2R 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 MAX-207HW2R 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 5.3 on page 45.
5.6.3 LAN TCP/IP
The MAX-207HW2R 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 MAX-207HW2R are preset in the factory with the
following values:
• IP address of 192.168.100.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives
you explicit DNS server address(es), see Section 5.3 on page 45.
5.6.4 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.
Chapter 5 The LAN Configuration Screens
MAX-207HW2R User’s Guide
52
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 MAX-207HW2R 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 MAX-207HW2R tells the DHCP
clients that it itself is the DNS server. When a computer sends a DNS query to the
MAX-207HW2R, the MAX-207HW2R 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
MAX-207HW2R can pass the DNS servers to the computers and the computers can
query the DNS server directly without the MAX-207HW2R’s intervention.
5.6.5 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 MAX-207HW2R will broadcast its routing table periodically and
incorporate the RIP information that it receives.
•In Only - the MAX-207HW2R will not send any RIP packets but will accept all
RIP packets received.
•Out Only - the MAX-207HW2R will send out RIP packets but will not accept any
RIP packets received.
•None - the MAX-207HW2R 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 MAX-207HW2R sends (it recognizes both formats when
receiving). RIP-1 is universally supported; but RIP-2 carries more information.
Chapter 5 The LAN Configuration Screens
MAX-207HW2R User’s Guide 53
RIP-1 is probably adequate for most networks, unless you have an unusual
network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference
being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.
5.6.6 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 MAX-207HW2R supports both IGMP version 1 (IGMP-v1) and IGMP version 2
(IGMP-v2). At start up, the MAX-207HW2R queries all directly connected
networks to gather group membership. After that, the MAX-207HW2R periodically
updates this information. IP multicasting can be enabled/disabled on the MAX-
207HW2R LAN and/or WAN interfaces in the web configurator (LAN; WAN).
Select None to disable IP multicasting on these interfaces.

6.1 Overview
Wi-Fi is a wireless networking technology and it is a synonym for wireless LAN.
The blue circle marks a wireless LAN in the following figure. Wireless clients (A and
B) connect to an access point (AP) to access other devices (such as the printer) or
the Internet. Your MAX-207HW2R works as an AP when you install a compatible
WLAN card.

•Use the General screen (see Section 6.2 on page 59) to turn the wireless
connection on or off, set up wireless security, configure the MAC filter, set up
Quality of Service and make other basic configuration changes.
•Use the MAC Filter screen (see Section 6.3 on page 64) to configure a MAC
(Media Access Control) address filter to restrict access to the wireless network.
•Use the WPS screen (see Section 6.4 on page 65) to set up WPS by pressing a
button or using a PIN.
You don’t necessarily need to use all these screens to set up your wireless
connection. For example, you may just want to set up a network name, a wireless
radio channel and some security in the General screen.
6.1.2 What You Need to Know About WIFI
Wireless Basics
• Every device in the same wireless network must use the same Service Set
IDentity (SSID).
The SSID is the name of the wireless network.
• If two wireless networks overlap, they should use different channels.
Like radio stations or television channels, each wireless network uses a specific
channel, or frequency, to send and receive information.
Wireless Network Construction
Wireless networks consist of wireless clients, access points and bridges.
• A wireless client is a radio connected to a user’s computer.
• An access point is a radio with a wired connection to a network, which can
connect with numerous wireless clients and let them access the network.
• A bridge is a radio that relays communications between access points and
wireless clients, extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
• An “infrastructure” type of network has one or more access points and one or
more wireless clients. The wireless clients connect to the access points.
• An “ad-hoc” type of network is one in which there is no access point. Wireless
clients connect to one another in order to exchange information.
Wired Equivalent Privacy (WEP)
WEP (Wired Equivalent Privacy) encrypts data transmitted between wired and
wireless networks to keep the transmission private. Although one of the original
wireless encryption protocols, WEP is also the weakest. Many people use it strictly
to deter unintentional usage of their wireless network by outsiders.
Chapter 6 The WIFI Configuration Screen
MAX-207HW2R User’s Guide 57
Authentication Type
The IEEE 802.11b/g standard describes a simple authentication method between
the wireless stations and AP. Three authentication types are defined: Auto, Open
and Shared. The MAX-207HW2R supports the WEP (Open) and WEP (Shared)
authentication types.
• Open mode is implemented for ease-of-use and when security is not an issue.
The wireless station and the AP or peer computer do not share a secret key.
Thus the wireless stations can associate with any AP or peer computer and listen
to any transmitted data that is not encrypted.
• Shared mode involves a shared secret key to authenticate the wireless station
to the AP or peer computer. This requires you to enable the wireless LAN
security and use same settings on both the wireless station and the AP or peer
computer.
Wi-Fi Protected Access (WPA)
WPA encrypts data transmitted between wired and wireless networks to keep the
transmission private. It affords vastly stronger security than its lower-tier
counterpart, WEP (Wired Equivalent Privacy). It comes in two different flavors:
WPA and WPA2. Always try to use WPA2 as it implements the full version of the
security standard while WPA does not.
WPA2
WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger
encryption, authentication and key management than WPA. It includes two data
encryption algorithms, Temporal Key Integrity Protocol (TKIP) and Advanced
Encryption Standard (AES) in the Counter mode with Cipher block chaining
Message authentication Code Protocol (CCMP). WPA2 reduces the number of key
exchange messages from six to four (CCMP 4-way handshake) and shortens the
time required to connect to a network. Other WPA2 authentication features that
are different from WPA include key caching and pre-authentication. These two
features are optional and may not be implemented in all wireless devices. See also
WPA.
Pre-Shared Key (PSK)
A pre-shared key is a password shared between the server and the client that
unlocks the algorithm used to encrypt the data traffic between them. Without the
proper password, the client and the server cannot communicate.
Chapter 6 The WIFI Configuration Screen
MAX-207HW2R User’s Guide
58
Security
Security stops unauthorized devices from using the wireless network. It can also
protect the information that is sent in the wireless network.Use the strongest
security that every wireless client in the wireless network supports.
Note: WPA2 or WPA2-PSK security is recommended.
• WPA2-PSK and WPA-PSK do not employ user authentication and are known as
the personal version of WPA.
• WEP is better than no security, but it is still possible for unauthorized devices to
figure out the original information pretty quickly.
MAC Filter
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address consists of twelve hexadecimal characters (0-9, and A to F), and it is
usually written in the following format: “0A:A0:00:BB:CC:DD”.
The MAC filter controls access to the wireless network. You can use the MAC
address of each wireless client to allow or deny access to the wireless network.

6.1.3 Before You Start
Before you start using these screens, ask yourself the following questions. See
Section 6.1.2 on page 56 if some of the terms used here do not make sense to
you.
• What wireless standards do the other wireless devices support (IEEE 802.11g,
for example)? What is the most appropriate standard to use?
• What security options do the other wireless devices support (WPA-PSK, for
example)? What is the best one to use?
• Do the other wireless devices support WPS (Wi-Fi Protected Setup)? If so, you
can set up a well-secured network very easily.
Even if some of your devices support WPS and some do not, you can use WPS to
set up your network and then add the non-WPS devices manually, although this
is somewhat more complicated to do.

6.5 Wireless LAN Technical Reference
This section discusses wireless LANs in depth. For more information, see the
appendix.
6.5.1 Additional Wireless Terms
The following table describes some wireless network terms and acronyms used in
the MAX-207HW2R’s Web Configurator.
6.5.2 Wireless Security Overview
The following sections introduce different types of wireless security you can set up
in the wireless network.
6.5.2.1 Network Name (SSID)
Normally, the MAX-207HW2R acts like a beacon and regularly broadcasts the SSID
in the area. You can hide the SSID instead, in which case the MAX-207HW2R does
not broadcast the SSID. In addition, you should change the default SSID to
something that is difficult to guess.
This type of security is fairly weak, however, because there are ways for
unauthorized wireless devices to get the SSID. In addition, unauthorized wireless
devices can still see the information that is sent in the wireless network.
Table 21 Additional Wireless Terms
TERM DESCRIPTION
RTS/CTS Threshold In a wireless network which covers a large area, wireless devices
are sometimes not aware of each other’s presence. This may cause
them to send information to the AP at the same time and result in
information colliding and not getting through.
By setting this value lower than the default value, the wireless
devices must sometimes get permission to send information to the
MAX-207HW2R. The lower the value, the more often the devices
must get permission.
If this value is greater than the fragmentation threshold value (see
below), then wireless devices never have to get permission to send
information to the MAX-207HW2R.
Preamble A preamble affects the timing in your wireless network. There are
two preamble modes: long and short. If a device uses a different
preamble mode than the MAX-207HW2R does, it cannot
communicate with the MAX-207HW2R.
Fragmentation
Threshold A small fragmentation threshold is recommended for busy networks,
while a larger threshold provides faster performance if the network
is not very busy.
Chapter 6 The WIFI Configuration Screen
MAX-207HW2R User’s Guide 67
6.5.2.2 MAC Filter
Every device that can use a wireless network has a unique identification number,
called a MAC address.1 A MAC address is usually written using twelve hexadecimal
characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC
address for each device in the wireless network, see the device’s User’s Guide or
other documentation.
You can use the MAC address filter to tell the MAX-207HW2R which devices are
allowed or not allowed to use the wireless network. If a device is allowed to use
the wireless network, it still has to have the correct information (SSID, channel,
and security). If a device is not allowed to use the wireless network, it does not
matter if it has the correct information.
This type of security does not protect the information that is sent in the wireless
network. Furthermore, there are ways for unauthorized wireless devices to get the
MAC address of an authorized device. Then, they can use that MAC address to use
the wireless network.
6.5.2.3 User Authentication
Authentication is the process of verifying whether a wireless device is allowed to
use the wireless network. You can make every user log in to the wireless network
before they can use it. However, every device in the wireless network has to
support IEEE 802.1x to do this.
For wireless networks, you can store the user names and passwords for each user
in a RADIUS server. This is a server used in businesses more than in homes. If you
do not have a RADIUS server, you cannot set up user names and passwords for
your users.
Unauthorized wireless devices can still see the information that is sent in the
wireless network, even if they cannot use the wireless network. Furthermore,
there are ways for unauthorized wireless users to get a valid user name and
password. Then, they can use that user name and password to use the wireless
network.
6.5.2.4 Encryption
Wireless networks can use encryption to protect the information that is sent in the
wireless network. Encryption is like a secret code. If you do not know the secret
code, you cannot understand the message.
1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks.
These kinds of wireless devices might not have MAC addresses.
2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 6 The WIFI Configuration Screen
MAX-207HW2R User’s Guide
68
The types of encryption you can choose depend on the type of authentication.
(See Section 6.5.2.3 on page 67 for information about this.)
For example, if the wireless network has a RADIUS server, you can choose WPA
or WPA2. If users do not log in to the wireless network, you can choose no
encryption, Static WEP, WPA-PSK, or WPA2-PSK.
Usually, you should set up the strongest encryption that every device in the
wireless network supports. For example, suppose you have a wireless network
with the MAX-207HW2R and you do not have a RADIUS server. Therefore, there is
no authentication. Suppose the wireless network has two devices. Device A only
supports WEP, and device B supports WEP and WPA. Therefore, you should set up
Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. The other types of encryption are better than none at all, but it is still
possible for unauthorized wireless devices to figure out the original information
pretty quickly.
When you select WPA2 or WPA2-PSK in your MAX-207HW2R, you can also select
an option (WPA compatible) to support WPA as well. In this case, if some of the
devices support WPA and some support WPA2, you should set up WPA2-PSK or
WPA2 (depending on the type of wireless network login) and select the WPA
compatible option in the MAX-207HW2R.
Many types of encryption use a key to protect the information in the wireless
network. The longer the key, the stronger the encryption. Every device in the
wireless network must have the same key.
6.5.3 WiFi Protected Setup
Your MAX-207HW2R supports WiFi Protected Setup (WPS), which is an easy way
to set up a secure wireless network. WPS is an industry standard specification,
defined by the WiFi Alliance.
WPS allows you to quickly set up a wireless network with strong security, without
having to configure security settings manually. Each WPS connection works

between two devices. Both devices must support WPS (check each device’s
documentation to make sure).
Depending on the devices you have, you can either press a button (on the device
itself, or in its configuration utility) or enter a PIN (a unique Personal Identification
Number that allows one device to authenticate the other) in each of the two
devices. When WPS is activated on a device, it has two minutes to find another
device that also has WPS activated. Then, the two devices connect and set up a
secure network by themselves.
6.5.3.1 Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each
WPS-enabled device, and allowing them to connect automatically. You do not need
to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS
PBC button in their configuration utilities instead of or in addition to the physical
button.
Take the following steps to set up WPS using the button.
1Ensure that the two devices you want to set up are within wireless range of one
another.
2Look for a WPS button on each device. If the device does not have one, log into its
configuration utility and locate the button (see the device’s User’s Guide for how to
do this). The MAX-207HW2R’s WPS button is in the rear panel as shown next.
Figure 24 The WPS Button on the MAX-207HW2R
3Press the button on one of the devices (it doesn’t matter which). For the MAX-
207HW2R you must press the WPS button for more than three seconds.
4Within two minutes, press the button on the other device. The registrar sends the
network name (SSID) and security key through an secure connection to the
enrollee.

The WAN Configuration Screens
7.1 Overview
Use the ADVANCED > WAN Configuration screens to set up your MAX-
207HW2R’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 73) lets you set up your
MAX-207HW2R’s Internet settings.
•The WiMAX Configuration screen (Section 7.3 on page 75) lets set up the
frequencies used by your MAX-207HW2R.
•The WiMAX FC Table screen (Section 7.4 on page 80) lets you view BS
information previously scanned by your MAX-207HW2R.
7.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
WiMAX
WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16
wireless networking standard, which provides high-bandwidth, wide-range
wireless service across wireless Metropolitan Area Networks (MANs). ZyXEL is a
member of the WiMAX Forum, the industry group dedicated to promoting and
certifying interoperability of wireless broadband products.
In a wireless MAN, a wireless-equipped computer is known either as a mobile
station (MS) or a subscriber station (SS). Mobile stations use the IEEE 802.16e
standard and are able to maintain connectivity while switching their connection
from one base station to another base station (handover) while subscriber stations
use other standards that do not have this capability (IEEE 802.16-2004, for
Chapter 7 The WAN Configuration Screens
MAX-207HW2R User’s Guide
72
example). The following figure shows an MS-equipped notebook computer MS1
moving from base station BS1’s coverage area and connecting to BS2.
Figure 25 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 26 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 MAX-207HW2R and
the base station are controlled by the base station. The MAX-207HW2R follows the
base station’s configuration.
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.
Chapter 7 The WAN Configuration Screens
MAX-207HW2R User’s Guide 73
The following figure shows a base station using an AAA server to authenticate
mobile station MS, allowing it to access the Internet.
Figure 27 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.

7.3.1 Frequency Ranges
The following figure shows the MAX-207HW2R searching a range of frequencies to
find a connection to a base station.
Figure 30 Frequency Ranges
In this figure, A is the WiMAX frequency range. “WiMAX frequency range” refers to
the entire range of frequencies the MAX-207HW2R is capable of using to transmit
and receive (see the Product Specifications appendix for details).
In the figure, B shows the operator frequency range. This is the range of
frequencies within the WiMAX frequency range supported by your operator
(service provider).
The operator range is subdivided into bandwidth steps. In the figure, each C is a
bandwidth step.
The arrow D shows the MAX-207HW2R searching for a connection.
Have the MAX-207HW2R search only certain frequencies by configuring the
downlink frequencies. Your operator can give you information on the supported
frequencies.
The downlink frequencies are points of the frequency range your MAX-207HW2R
searches for an available connection. Use the Site Survey screen to set these
bands. You can set the downlink frequencies anywhere within the WiMAX
frequency range. In this example, the downlink frequencies have been set to
search all of the operator range for a connection.
7.3.2 Configuring Frequency Settings
You need to set the MAX-207HW2R to scan one or more specific radio frequencies
to find an available connection to a WiMAX base station.
Use the WiMAX Configuration screen to define the radio frequencies to be
searched for available wireless connections.
Note: It may take several minutes for the MAX-207HW2R to find a connection.

The Port Configuration Screens
8.1 Overview
Use these screens to enable NAT and configure port forwarding for the MAX-
207HW2R.
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.

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 MAX-207HW2R.
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.
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.

the Properties button. Note the entry for the Computer Name field and enter
it as the System Name.
• In Windows XP: Click Start > My Computer > View system information and
then click the Computer Name tab. Note the entry in the Full computer
name field and enter it as the MAX-207HW2R System Name.
Chapter 9 The System Configuration Screens
MAX-207HW2R User’s Guide

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 MAX-207HW2R 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 MAX-207HW2R 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.
9.2 Dynamic DNS
Dynamic DNS allows you to update your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, 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.

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 Setting screen (Section 10.2 on page 99) lets you setup and maintain
your SIP account(s) in the MAX-207HW2R.
•The Advanced SIP Settings screen (Section 10.2.1 on page 100) lets you set
up and maintain advanced settings for each SIP account
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
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
Chapter 10 The Service Configuration Screens
MAX-207HW2R User’s Guide
98
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 MAX-207HW2R 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 MAX-
207HW2R.

MAX-207HW2R User’s Guide 99
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 MAX-
207HW2R.
• Connect your MAX-207HW2R 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

Chapter 10 The Service Configuration Screens
MAX-207HW2R User’s Guide 101
•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.
10.2.1.2 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.729 requires only 8 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.
The MAX-207HW2R 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 100
DTMF Mode controls how the MAX-207HW2R 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.
•SIP INFO - send the DTMF tones in SIP messages.

10.3.1 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).
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.

10.3.2 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.
10.3.3 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 42 SIP User Agent
10.3.4 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
MAX-207HW2R User’s Guide
108
2The SIP proxy server forwards the call invitation to C.
Figure 43 SIP Proxy Server
10.3.5 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 44 SIP Redirect Server
10.3.6 NAT and SIP
The MAX-207HW2R must register its public IP address with a SIP register server.
If there is a NAT router between the MAX-207HW2R and the SIP register server,
the MAX-207HW2R probably has a private IP address. The MAX-207HW2R 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
MAX-207HW2R’s IP address from inside the SIP message and maps it to your SIP
identity. If the MAX-207HW2R has a private IP address listed in the SIP message,
the SIP server cannot map it to your SIP identity. See Chapter 8 The Port
Configuration Screens for more information.
Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to
allow the MAX-207HW2R to list its public IP address in the SIP messages.
10.3.7 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.

10.3.8 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 45 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.

settings and custom tones for the phone port on the MAX-207HW2R. 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 112) lets you control which
SIP accounts each phone uses.
•The Common screen (Section 11.3 on page 115) lets you activate and
deactivate immediate dialing.
•The Region screen (Section 11.4 on page 116) lets you maintain settings that
often depend on the region of the world in which the MAX-207HW2R 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 MAX-207HW2R reduce the bandwidth that a call uses by not transmitting
“silent packets” when you are not speaking.
When using VAD, the MAX-207HW2R 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

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 MAX-207HW2R 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.

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 MAX-207HW2R, 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 MAX-207HW2R 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 importmanage public key certificates
on the MAX-207HW2R.
The MAX-207HW2R 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 128) lets you import the
MAX-207HW2R’s CA-signed certificates.
•The Trusted CAs screen (Section 13.3 on page 129) lets you import trusted
CA-signed certificates.
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
MAX-207HW2R to generate certification requests that contain identifying

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 MAX-207HW2R 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 MAX-207HW2R does not trust a certificate if any
certificate on its path has expired or been revoked.
Chapter 13 The Certificates Screens
MAX-207HW2R User’s Guide 131
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 MAX-
207HW2R 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 MAX-207HW2R 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 MAX-207HW2R act as a certification authority and sign its own
certificates.
13.4.1.3 Factory Default Certificate
The MAX-207HW2R 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 MAX-
207HW2R 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
MAX-207HW2R User’s Guide
132
13.4.2 Verifying a Certificate
Before you import a certificate into the MAX-207HW2R, you should verify that you
have the correct certificate. This is especially true of trusted certificates since the
MAX-207HW2R 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”.)

The Remote Management
Screens
14.1 Overview
Use the TOOLS > Remote MGMT screens to control which computers can use
which services to access the MAX-207HW2R on each interface.
Remote management allows you to determine which services/protocols can access
which MAX-207HW2R interface (if any) from which computers.
You may manage your MAX-207HW2R from a remote location via:
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 MAX-
207HW2R 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.

14.1.2 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:
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 MAX-207HW2R 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 MAX-207HW2R’s WAN IP address when configuring from the WAN.
• Use the MAX-207HW2R’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 MAX-207HW2R 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.
SNMP
Simple Network Management Protocol (SNMP) is a protocol used for exchanging
management information between network devices. SNMP is a member of the
Chapter 14 The Remote Management Screens
MAX-207HW2R User’s Guide 137
TCP/IP protocol suite. Your MAX-207HW2R supports SNMP agent functionality,
which allows a manager station to manage and monitor the MAX-207HW2R
through the network. The MAX-207HW2R 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.

14.5 SNMP
An SNMP managed network consists of two main types of component: agents and
a manager.
Figure 60 SNMP Management Model
An agent is a management software module that resides in a managed device (the
MAX-207HW2R). 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.
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 MAX-207HW2R 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.
Chapter 14 The Remote Management Screens
MAX-207HW2R User’s Guide 141
• 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.
14.5.1 SNMP Traps
The MAX-207HW2R sends traps to the SNMP manager when any of the following
events occurs:
Table 56 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.

CHAPTER 15
The Firewall Screens
15.1 Overview
Use the TOOLS > Firewall screens to manage MAX-207HW2R’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.
15.1.1 What You Can Do in This Chapter
•The General screen (Section 15.2 on page 146) lets you configure the basic
settings for your firewall.
•The Services screen (Section 15.3 on page 149) 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.
15.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
About the MAX-207HW2R Firewall
The MAX-207HW2R firewall is a stateful inspection firewall and is designed to
protect against Denial of Service attacks when activated. The MAX-207HW2R's
purpose is to allow a private Local Area Network (LAN) to be securely connected to
Chapter 15 The Firewall Screens
MAX-207HW2R User’s Guide
146
the Internet. The MAX-207HW2R 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 MAX-207HW2R 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 MAX-207HW2R 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.
15.2 Firewall Setting
This section describes firewalls and the built-in MAX-207HW2R’s firewall features.
15.2.1 Firewall Rule Directions
Figure 64 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 15 The Firewall Screens
MAX-207HW2R User’s Guide 147
LAN-to-LAN/MAX-207HW2R means the LAN to the MAX-207HW2R LAN interface.
This is always allowed, as this is how you manage the MAX-207HW2R 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/MAX-207HW2R firewall rules. WAN-
to-WAN/MAX-207HW2R firewall rules are Internet to the MAX-207HW2R 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/MAX-207HW2R packets to log.
Forwarded WAN-to-LAN packets are not considered alerts.
15.2.2 Triangle Route
When the firewall is on, your MAX-207HW2R 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 MAX-207HW2R to protect your LAN
against attacks.
