LTE
1.1 Overview
The Device is an LTE (Long Term Evolution) device including an outdoor unit (ODU) and an indoor
unit (IDU). The LTE Device provides a complete security solution with a robust firewall based on
Stateful Packet Inspection (SPI) technology and Denial of Service (DoS).
See the chapter on product specifications for a full list of features.
1.2 Applications for the LTE Device
Here are some example uses for which the LTE Device is well suited.
Introduction
1.2.1 Internet Access
Your LTE Device provides Internet access by connecting to an LTE network wirelessly.
Computers can connect to the LTE Device’s ETHERNET ports.
Figure 1 LTE Device’s Internet Access Application
1.2.2 Wireless Connection
By default, the wireless LAN (WLAN) is enabled on the LTE Device. Once Wireless is enabled, IEEE
802.11b/g/n compliant clients can wirelessly connect to the LTE De vice to access network
LTE6101 User’s Guide 13

resources. You can set up a wireless network with WPS (WiFi Protected Setup) or manually add a
client to your wireless network.
Figure 2 Wireless Connection Application
1.3 The WLAN Button
You can use the WIRELESS ON/OFF button on top of the device to turn the wireless LAN on or off.
You can also use it to activate WPS in order to quickly set up a wireless network with strong
security.
Turn the Wireless LAN On or Off
1 Make sure the PWR/SYS LED is on (not blinking).
2 Press the WIRELESS ON/OFF button for one second and release it. The WLAN/WPS LED should
change from on to off or vice versa.
Activate WPS
1 Make sure the PWR/SYS LED is on (not blinking).
2 Press the WIRELESS ON/OFF button for more than five seconds and release it. Press the WPS
button on another WPS-enabled device within range of the LTE Device. The WLAN/WPS LED
should flash while the LTE Device sets up a WPS connection with the wireless device.
You must activate WPS in the LTE Device and in another wireless device within two minutes of each
other. See Section 5.7.6 on page 59 for more information.

1.4 Ways to Manage the LTE Device
• Web Configurator. This is for management of the LTE Device using a (supported) web browser.
1.5 Good Habits for Managing the LTE Device
Do the following things regularly to make the LTE Device more secure and to manage the LTE
Device 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 device becomes unstable or even crashes. If you
forget your password to access the Web Configurator, you will have to reset the LTE Device to its
factory default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the LTE Device. You could simply restore your last configuration. Write down
any information your ISP provides you.

WAN
LAN
This chapter discusses the LTE Device’s Broadband screens. Use these screens to configure your
LTE Device for Internet access.
A WAN (Wide Area Network) connection is an outside connection to another network or the
Internet. It connects your private networks, such as a LAN (Local Area Network) and other
networks, so that a computer in one location can communicate with computers in other locations.
This LTE Device supports LTE connection for the WAN only.

Broadband
4.1.1 What You Can Do in this Chapter
•Use the Broadband screen to view or edit an L TE WAN interface. Y o u can also configure the W AN
settings on the LTE Device for Internet access (Section 4.2 on page 34).
•Use the SIM screen to enter the PIN of your SIM card (Section 4.3 on page 36).
4.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
LTE6101 User’s Guide 33
Page 34
Chapter 4 Broadband
WAN IP Address
The WAN IP address is an IP address for the L TE Device, which makes it accessible from an outside
network. It is used by the LTE Device to communicate with other devices in other networks. It can
be static (fixed) or dynamically assigned by the ISP each time the LTE Device tries to access the
Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es).
APN
Access Point Name (APN) is a unique string which indicates an LTE network. An APN is required for
LTE stations to enter the LTE network and then the Internet.
4.1.3 Before You Begin
You may need to know your Internet access settings such as LTE APN, WAN IP address and SIM
card’s PIN code if the INTERNET light on your LTE Device is off. Get this information from your
service provider.
4.2 The Broadband Screen
The LTE Device must have a WAN interface to allow users to use the LTE connection to access the
Internet. Use the Broadband screen to view or modify a WAN interface.
Click Network Setting > Broadband. The following screen opens.

4.4 Technical Reference
The following section contains additional technical information about the LTE Device features
described in this chapter.
Encapsulation
Be sure to use the encapsulation method required by your ISP. The LTE Device supports the
following methods:
IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a
different one each time. The Single User Account feature can be enabled or disabled if you have
either a dynamic or static IP. However the encapsulation method assigned influences your choices
for IP address and default gateway.
LTE6101 User’s Guide
37
Page 38
Chapter 4 Broadband
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa. The DNS server is ex tremely important be ca use without it, you m ust know the IP address of
a computer before you can access it.
The LTE Device can get the DN S server addresses in the following ways.
1 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
2 If your ISP dynamically assigns the DNS server IP addresses (along with the LTE Device’s WAN IP
address), set the DNS server fields to get the DNS server address from the ISP.

5.1 Overview
This chapter describes the LTE Device’s Network Setting > Wireless screens. Use these screens
to set up your LTE Device’s wireless connection.
5.1.1 What You Can Do in this Chapter
•Use the General screen to enable the Wireless LAN, enter the SSID and select the wireless
security mode (Section 5.2 on page 43).
•Use the More AP screen to set up multiple wireless networks on your LTE Device (Section 5.3 on
page 49).
•Use the WPS screen to enable or disable WPS, view or generate a security PIN (Personal
Identification Number) (Section 5.4 on page 51).
•Use the WMM screen to enable Wi-Fi MultiMedia (WMM) to ensure quality of service in wireless
networks for multimedia applications (Section 5.5 on page 52).
•Use the Scheduling screen to schedule a time period for the wireless LAN to operate each day
(Section 5.6 on page 54).
CHAPTER 5
Wireless
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.
5.1.2 Wireless Network Overview
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.
LTE6101 User’s Guide 41
Page 42
Chapter 5 Wireless
The following figure provides an example of a wireless network.
Figure 18 Example of a Wireless Network
The wireless network is the part in the blue circle. In this wireless network, devices A and B use the
access point (AP) to interact with the other devices (such as the printer) or with the Internet. Your
LTE Device is the AP.
Every wireless network must follow these basic guidelines.
• Every device in the same wireless network must use the same SSID.
The SSID is the name of the wireless network. It stands for Service Set IDentifier.
• If two wireless networks overlap, they should use a different channel.
Like radio stations or television channels, each wireless network uses a specific channel, or
frequency, to send and receive information.
• Every device in the same wireless network must use security compatible with the AP.
• Security stops unauthorized devices from using the wireless network. It can also protect the
information that is sent in the wireless network.
Radio Channels
In the radio spectrum, there are certain frequency bands allocated for unlicensed, civilian use. For
the purposes of wireless networking, these bands are divided into numerous channels. This allows a
variety of networks to exist in the same place without interfering with one another. When you
create a network, you must select a channel to use.
Since the available unlicensed spectrum varies from one country to another, the number of
available channels also varies.
42
A channel is the radio frequency(ies) used by wireless devices to transmit and receive data.
Channels available depend on your geographical area. You may have a choice of channels (for your
region) so you should use a channel different from an adjacent AP (access point) to reduce
interference. Interference occurs when radio signals from different access points overlap causing
interference and degrading performance.
LTE6101 User’s Guide
Page 43
Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should
be on a channel at least five channels away from a channel that an adjacent AP is using. For
example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to
select a channel between 6 or 11.
5.1.3 Before You Begin
Before you start using these screens, ask yourself the following questions. See Section 5.7 on page
54 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 wellsecured network very easily.
Even if some of your devices support WPS and some do not, you can use WPS to set up your
network and then add the non-WPS devices manually, although this is somewhat more
complicated to do.
• What advanced options do you want to configure, if any? If you want to configure advanced
options, ensure that you know precisely what you want to do. If you do not want to configure
advanced options, leave them alone.

Select No Security to allow wireless stations to communicate with the access points without any
data encryption or authentication.
Note: If you do n ot enable any wi r eless security on your LTE Device, your netwo rk is
accessible to any wireless networking device that is within range.

5.2.2 Basic (Static WEP/Shared WEP Encryption)
WEP encryption scrambles the data transmitted between the wireless stations and the access points
(AP) to keep network communications private. Both the wireless stations and the access points
must use the same WEP key.
There are two types of WEP authentication namely, Open System (Static WEP) and Shared Key
(Shared WEP).
LTE6101 User’s Guide
45
Page 46
Chapter 5 Wireless
Open system 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 key 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.
In order to configure and enable WEP encryption, click Network Settings > Wireless to display
the General screen. Select Basic as the security level. Then select Static WEP or Shared WEP
from the Security Mode list.

5.2.3 More Secure (WPA(2)-PSK)
The WPA-PSK security mode provides both improved data encryption and user authentication over
WEP. Using a Pre-Shared Key (PSK), both the L TE Device and the connecting client share a common
password in order to validate the connection. This type of encryption, while robust, is not as strong
as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode is a newer , more robust version of
the WPA encryption standard. It offers slightly better security, although the use of PSK makes it
less robust than it could be.

5.2.4 WPA(2) Authentication
The WPA2 security mode is currently the most robust form of encryption for wireless networks. It
requires a RADIUS server to authenticate user credentials and is a full implementation the security
protocol. Use this security option for maximum protection of your network. However, it is the least
backwards compatible with older devices.
The WPA security mode is a security subset of WPA2. It requires the presence of a RADIUS server
on your network in order to validate user credentials. This encryption standard is slightly older than
WPA2 and therefore is more compatible with older devices.

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

By setting this value lower than the def ault value, the wireless devices must sometimes get
permission to send information to the LTE Device. 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

cannot communicate with the LTE Device.
A small fragmentation threshold is recommended for busy networks, while a larger
threshold provides faster performance if the network is not very busy.
Chapter 5 Wireless
5.7.2 Wireless Security Overview
By their nature, radio communications are simple to intercept. For wireless data networks, this
means that anyone within range of a wireless network without security can not only read the data
passing over the airwaves, but also join the network. Once an unauthorized person has access to
the network, he or she can steal information or introduce malware (malicious software) intended to
compromise the network. For these reasons, a variety of security systems have been developed to
ensure that only authorized people can use a wireless data network, or understand the data carried
on it.
These security standards do two things. First, they authenticate. This means that only people
presenting the right credentials (often a username and password, or a “key” phrase) can access the
network. Second, they encrypt. This means that the information sent over the air is encoded. Only
people with the code key can understand the information, and only people who have been
authenticated are given the code key.
These security standards vary in effectiveness. Some can be broken, such as the old Wired
Equivalent Protocol (WEP). Using WEP is better than using no security at all, but it will not keep a
determined attacker out. Other security standards are secure in themselves but can be broken if a
user does not use them properly . For example, the WP A -PSK securit y standard is very secure if you
use a long key which is difficult for an attacker’s software to guess - for example, a twenty-letter
long string of apparently random numbers and letters - but it is not very secure if you use a short
key which is very easy to guess - for example, a three-letter word from the dictionary.
Because of the damage that can be done by a malicious attacker, it’s not just people who have
sensitive information on their network who should use security. Everybody who uses any wireless
network should ensure that effective security is in place.
A good way to come up with effective security keys, passwords and so on is to use obscure
information that you personally will easily remember, and to enter it in a way that appears random
LTE6101 User’s Guide

Chapter 5 Wireless
and does not include real words. For example, if your mother owns a 1970 Dodge Challenger and
her favorite movie is Vanishing Point (which you know was made in 1971) you could use
“70dodchal71vanpoi” as your security key.
The following sections introduce different types of wireless security you can set up in the wireless
network.
5.7.2.1 SSID
Normally, the LTE Device acts like a beacon and regularly broadcasts the S SID in the area. You can
hide the SSID instead, in which case the LTE Device 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.
5.7.2.2 MAC Address Filter
Every device that can use a wireless network has a unique identification number, called a MAC
address.
00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC add ress 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 LTE Device 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.

A MAC address is usually written using twelve hexadecimal characters2; for example,
5.7.2.3 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 using 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.
56
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.
LTE6101 User’s Guide
Page 57
5.7.2.4 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.
The types of encryption you can choose depend on the type of authentication. (See Section 5.7.2.3
on page 56 for information about this.)
Table 20 Types of Encryption for Each Type of Authentication
Weakest No Security WPA
Strongest WPA2-PSK WPA2
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.
Chapter 5 Wireless
NO AUTHENTICATION RADIUS SERVER
Static WEP
WPA-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 LTE Device 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 LTE Device, 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 LTE Device.
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.
5.7.3 Signal Problems
Because wireless networks are radio networks, their signals are subject to limitations of distance,
interference and absorption.
Problems with distance occur when the two radios are too far apart. Problems with interference
occur when other radio waves interrupt the data signal. Interference may come from other radio
transmissions, such as military or air traffic control communications, or from machines that are
coincidental emitters such as electric motors or microwaves. Problems with absorption occur when
physical objects (such as thick walls) are between the two radios, muffling the signal.

Chapter 5 Wireless
5.7.4 BSS
A Basic Service Set (BSS) exists when all communications between wireless stations or between a
wireless station and a wired network client go through one access point (AP).
Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS traffic blocking is
disabled, wireless station A and B can access the wired network and communicate with each other .
When Intra-BSS traffic blocking is enabled, wireless station A and B can still access the wired
network but cannot communicate with each other.
Figure 29 Basic Service set
5.7.5 MBSSID
Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well
as the cost of buying extra APs, there is also the possibility of channel interference. The LTE
Device’s MBSSID (Multiple Basic Service Set IDentifier) function allows you to use one access point
to provide several BSSs simultaneously. You can then assign varying QoS priorities and/or security
modes to different SSIDs.
Wireless devices can use different BSSIDs to associate with the same AP.
5.7.5.1 Notes on Multiple BSSs
• A maximum of eight BSSs are allowed on one AP simultaneously.
• You must use di f fe rent keys for different BSSs. If two wireless devices have different BSSIDs
(they are in different BSSs), but have the same keys, they may hear each other’s
communications (but not communicate with each other).
• MBSSID should not replace but rather be used in conjunction with 802.1x security.

5.7.6 WiFi Protected Setup (WPS)
Your LTE Device 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.
5.7.6.1 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.
Chapter 5 Wireless
Take the following steps to set up WPS using the button.
1 Ensure that the two devices you want to set up are within wireless range of one another.
2 Look 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 - for the LTE Device,
see Section 5.4 on page 51).
3 Press the button on one of the devices (it doesn’t matter which). For the L TE Device you must press
the WPS button for more than three seconds.
4 Within 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.
If you need to make sure that WPS worked, check the list of associated wireless clients in the AP’s
configuration utility. If you see the wireless client in the list, WPS was successful.
5.7.6.2 PIN Configuration
Each WPS-enabled device has its own PIN (Personal Identification Number). This may either be
static (it cannot be changed) or dynamic (in some devices you can generate a new PIN by clicking
on a button in the configuration interface).
Use the PIN method instead of the push-button configuration (PBC) method if you want to ensure
that the connection is established between the devices you specify, not just the first two devices to
activate WPS in range of each other. However, you need to log into the configuration interfaces of
both devices to use the PIN method.
When you use the PIN method, y ou must enter the PIN from one device ( usually the wireless cl ient)
into the second device (usually the Access Point or wireless router). Then, when WPS is activated
LTE6101 User’s Guide
59
Page 60
Chapter 5 Wireless
on the first device, it presents its PIN to the second device. If the PIN matches, one device sends
the network and security information to the other, allowing it to join the network.
Take the following steps to set up a WPS connection between an access point or wireless router
(referred to here as the AP) and a client device using the PIN method.
1 Ensure WPS is enabled on both devices.
2 Access the WPS section of the AP’s configuration interface. See the device’s User’ s Guide for how to
do this.
3 Look for the client’s WPS PIN; it will be displayed either on the device, or in the WPS section of the
client’s configuration interface (see the device’s User’s Guide for how to find the WPS PIN - for the
LTE Device, see Section 5.4 on page 51).
4 Enter the client’s PIN in the AP’s configuration interface.
5 If the client device’s configuration interface has an area for entering another device’s PIN, you can
either enter the client’s PIN in the AP, or enter the AP’s PIN in the client - it does not matter which.
6 Start WPS on both devices within two minutes.
7 Use the configuration utility to activate WPS, not the push-button on the device itself.
8 On a computer connected to the wireless client, try to connect to the Internet. If you can connect,
WPS was successful.
If you cannot connect, check the list of associated wireless clients in the AP’s configuration utility . If
you see the wireless client in the list, WPS was successful.

5.7.6.3 How WPS Works
When two WPS-enabled devices connect, each device must assume a specific role. One device acts
as the registrar (the device that supplies network and security settings) and the other device acts
as the enrollee (the device that receives network and security settings. The registrar creates a
secure EAP (Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the
WPA-PSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK or WPA2-PSK is used
depends on the standards supported by the devices. If the registrar is already part of a network, it
sends the existing information. If not, it generates the SSID and WPA(2)-PSK randomly.

The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a
WPS-enabled access point.
Figure 31 How WPS works
5.7.6.4 Example WPS Network Setup
The roles of registrar and enrollee last only as long as the WPS setup process is active (two
minutes). The next time you use WPS, a different device can be the registrar if necessary.
The WPS connection process is like a handshake; only two devices participate in each WPS
transaction. If you want to add more devices you should repeat the process with one of the existing
networked devices and the new device.
Note that the access point (AP) is not always the registrar, and the wireless client is not always the
enrollee. All WPS-certified APs can be a registrar, and so can some WPS-enabled wireless clients.
By default, a WPS devices is “unconfigured”. This means that it is not part of an existing network
and can act as either enrollee or registrar (if it supports both functions). If the registrar is
unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once a
WPS-enabled device has connected to another device using WPS, it becomes “configured”. A
configured wireless client can still act as enrollee or registrar in subsequent WPS connections, but a
configured access point can no longer act as enrollee. It will be the registrar in all subsequent WPS
connections in which it is involved. If you want a configured AP to act as an enrollee, you must reset
it to its factory defaults.
This section shows how security settings are distributed in an example WPS setup.
The following figure shows an example network. In step 1, both AP1 and Client 1 are
unconfigured. When WPS is activated on both, they perform the handshake. In this example, AP1

is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security
information to set up the network, since it is unconfigured and has no existing information.
Figure 32 WPS: Example Network Step 1
In step 2, you add another wireless client to the network. You know that Client 1 supports registrar
mode, but it is better to use AP1 for the WPS handshake with the new client since you must
connect to the access point anyway in order to use the network. In this case, AP1 must be the
registrar, since it is configured (it already has security information for the network). AP1 supplies
the existing security information to Client 2.

In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you
cannot use AP1 for the WPS handshake with the new access point. However, you know that Client
2 supports the registrar function, so you use it to perform the WPS handshake instead.
Figure 34 WPS: Example Network Step 3
5.7.6.5 Limitations of WPS
WPS has some limitations of which you should be aware.
• WPS works in Infrastructure networks only (where an AP and a wireless client communicate). It
does not work in Ad-Hoc networks (where there is no AP).
• When you use WPS, it works between two devices only. You cannot enroll multiple devices
simultaneously, you must enroll one after the other.
For instance, if you have two enrollees and one registrar you must set up the first enrollee (by
pressing the WPS button on the registrar and the first enrollee, for example), then check that it
successfully enrolled, then set up the second device in the same way.
• WPS works only with other WPS-enabled devices. However, you can still add non-WPS devices to
a network you already set up using WPS.
WPS works by automatically issuing a randomly-generated WPA-PSK or WPA2-PSK pre-shared
key from the registrar device to the enrollee devices. Whether the network uses WPA-PSK or
WPA2-PSK depends on the device. You can check the configuration interface of the registrar
device to discover the key the network is using (if the device supports this feature). Then, you
can enter the key into the non-WPS device and join the network as normal (the non-WPS device
must also support WPA-PSK or WPA2-PSK).
64
LTE6101 User’s Guide
Page 65
Chapter 5 Wireless
• When you use the PBC method, there is a short period (from the moment you press the button
on one device to the moment you press the button on the other device) when any WPS-enabled
device could join the network. This is because the registrar has no way of identifying the
“correct” enrollee, and cannot differentiate between your enrollee and a rogue device. This is a
possible way for a hacker to gain access to a network.
You can easily check to see if this has happened. WPS works between only two devices
simultaneously , so if another device has enrolled your device will be unable to enroll, and will not
have access to the network. If this happens, open the access point’s configuration interface and
look at the list of associated clients (usually displayed by MAC address). It does not matter if the
access point is the WPS registrar, the enrollee, or was not involved in the WPS handshake; a
rogue device must still associate with the access point to gain access to the network. Check the
MAC addresses of your wireless clients (usually printed on a label on the bottom of the device). If
there is an unknown MAC address you can remove it or reset the AP.

6.1 Overview
WAN
LAN
A Local Area Network (LAN) is a shared communication system to which many computers are
attached. A LAN is usually located in one immediate area such as a building or floor of a building.
The LAN screens can help you configure a LAN DHCP server and manage IP addresses.
CHAPTER 6
Home Networking
6.1.1 What You Can Do in this Chapter
•Use the LAN Setup screen to set the LAN IP address, DHCP, subnet mask, and DNS settings
(Section 6.2 on page 69).
•Use the Static DHCP screen to assign IP addresses on the LAN to specific individual computers
based on their MAC Addresses (Section 6.3 on page 70).
•Use the UPnP screen to enable UPnP (Section 6.4 on page 71).
6.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
6.1.2.1 About LAN
IP Address
Similar to the way houses on a street share a common street name, so too do computers on a LAN
share one common network number. This is known as an Internet Protocol address.
LTE6101 User’s Guide 67
Page 68
Chapter 6 Home Networking
Subnet Mask
The subnet mask specifies the network number portion of an IP address. Your LTE Device 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 LTE Device unless you are instructed to do otherwise.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows clients to obtain TCP/IP configuration at startup from a server. This LTE Device has a built-in DHCP server capability that assigns IP addresses
and DNS servers to systems that support DHCP client capability.
DNS
DNS (Domain Name System) maps a domain name to its corresponding IP address and vice versa.
The DNS server is extremely important because without it, you must know the IP address of a
computer before you can access it. The DNS server addresses you enter when you set up DHCP are
passed to the client machines along with the assigned IP address and subnet mask.
6.1.2.2 About UPnP
How do I know if I'm using UPnP?
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP
compatible device installed on your network will appear as a separate icon. Selecting the icon of a
UPnP device will allow you to access the information and properties of that device.
Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configur ation may also
be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the LTE Device allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.

The LTE Device usually uses the default gateway to route outbound traffic from computers on the
LAN to the Internet. To have the LTE Device send data to devices not reachable through the default
gateway, use static routes.
For example, the next figure shows a computer (A) connected to the LTE Device’s LAN interface.
The L TE Device routes most tr affic from A to the Internet through the LTE Device’s default gatew ay

8.1 Overview
This chapter discusses the LTE Device’s QoS screens. Use these screens to set up your LTE Device
to use QoS for traffic management.
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. QoS allows the LTE Device to group
and prioritize application traffic and fine-tune network performance.
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.
The LTE Device assigns each packet a priority and then queues the packet accordingly. Packets
assigned a high priority are processed more quickly than those with low priority if there is
congestion, allowing time-sensitive applications to flow more smoothly. Time-sensitive applications
include both those that require a low level of latency (delay) and a low level of jitter (variations in
delay) such as Internet gaming, and those for which jitter alone is a problem such as Internet radio
or streaming video.
CHAPTER 8
Quality of Service (QoS)
8.1.1 What You Can Do in this Chapter
•Use the General screen to enable QoS, set the bandwidth, and allow the LTE Device to
automatically assign priority to upstream traffic according to the IP precedence or packet length
(Section 8.2 on page 78).
•Use the Queue Setup screen to configure QoS queue assignment (Section 8.3 on page 79).
•Use the Class Setup screen to set up classifiers to sort traffic into different flows and assign
priority and define actions to be performed for a classified traffic flow (Section 8.4 on page 80).
•Use the Monitor screen to view the LTE Device’s QoS-related packet statistics (Section 8.5 on
page 84).
8.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
QoS versus Cos
QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given
the same priority. CoS (class of service) is a way of managing traffic in a network by grouping
similar types of traffic together and treating each type as a class. You can use CoS to give different
priorities to different packet types.
LTE6101 User’s Guide 77
Page 78
Chapter 8 Qual ity of Service (QoS)
CoS technology includes DiffServ (Differentiated Services or DS). DiffServ is a new protocol and
defines a new DS field, which replaces the eight-bit ToS (Type of Service) field in the IP header.
Tagging and Marking
In a QoS class, you can configure whether to add or change the DSCP (DiffServ Code Point) v alue in
a matched packet. When the packet passes through a compatible network, the networking device,
such as a backbone switch, can provide specific treatment or service based on the tag or marker.

8.6 QoS Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
8.6.1 DiffServ
QoS is used to prioritize source-to-destination traffic flows. All packets in the flow are given the
same priority. You can use CoS (class of service) to give different priorities to different packet
types.
DiffServ (Differentiated Services) 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.
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.
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.
LTE6101 User’s Guide
DSCP (6 bits) Unused (2 bits)
85
Page 86
Chapter 8 Qual ity of Service (QoS)
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 kinds of forwarding. Resources can then be allocated according to the DSCP
values and the configured policies.

Network Address Translation (NAT)
9.1 Overview
NAT (Network Address Translation - NA T, RFC 1631) is the translation of the IP address of a host in
a packet, for example, the source address of an outgoing packet, used within one network to a
different IP address known within another network.
9.1.1 What You Can Do in this Chapter
•Use the Port Forwarding screen to configure forward incoming service requests to the server(s)
on your local network (Section 9.2 on page 88).
•Use the DMZ screen to view and configure the IP address of your network DMZ. (Section 9.3 on
page 91).
•Use the Sessions screen to limit the number of concurrent NAT sessions each client can use
(Section 9.4 on page 91).
CHAPTER 9
9.1.2 What You Need To Know
The following terms and concepts may help as you read this chapter.
Inside/Outside and Global/Local
Inside/outside denotes where a host is located relative to the LTE Device, for example, the
computers of your subscribers are the inside hosts, while the web servers on the Internet are the
outside hosts.
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for
example, the local address refers to the IP address of a host when the packet is in the local
network, while the global address refers to the IP address of the host when the same packet is
traveling in the WAN side.
NAT
In the simplest form, NAT changes the source IP address in a packet received from a subscriber
(the inside local address) to another (the inside global address) before forwarding the packet to the
WAN side. When the response comes back, NAT translates the destination address (the inside
global address) back to the inside local address before forwarding it to the original inside host.

Port Forwarding
A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP,
that you can make visible to the outside world even though NAT makes your whole inside network
appear as a single computer to the outside world.
Finding Out More
See Section 9.5 on page 92 for advanced technical information on NAT.
9.2 The Port Forwarding Screen
Use the 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 forw arde d , an d 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. You can allocate a serv er IP address that corresponds to a port or
a range of ports.
The most often used port numbers and services are shown in Appendix D on page 207. Please refer
to RFC 1700 for further information about port numbers.
Note: Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, r e fer to your ISP.
Configuring Servers Behind Port Forwarding (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 10.0.0.35 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.

9.5 Technical Reference
This section provides some technical background information about the topics covered in this
chapter.
9.5.1 NAT Definitions
Inside/outside denotes where a host is located relative to the LTE Device, for example, the
computers of your subscribers are the inside hosts, while the web servers on the Internet are the
outside hosts.
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for
example, the local address refers to the IP address of a host when the packet is in the local
network, while the global address refers to the IP address of the host when the same packet is
traveling in the WAN side.
Note that inside/outside refers to the location of a host, while global/local refers to the IP address
of a host used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in
a packet when the packet is still in the local network, while an inside global address (IGA) is the IP
address of the same inside host when the packet is on the WAN side. The following table
summarizes this information.
Table 37 NAT Definitions
ITEM DESCRIPTION
Inside This refers to the host on the LAN.
Outside This refers to the host on the WAN.
Local This refers to the packet address (source or destination) as the packet travels on the LAN.
Global This refers to the packet address (source or destination) as the packet travels on the WAN.
NAT never changes the IP address (either local or global) of an outside host.
9.5.2 What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber
(the inside local address) to another (the inside global address) before forwarding the packet to the

that the IP address (either local or global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP .
In addition, you can designate servers, for example, a web server and a Telnet server, on your local
network and make them accessible to the outside world. If you do not define any servers, NAT
offers the additional benefit of firewall protection. With no servers defined, your LTE Device filters
out all incoming inquiries, thus preventing intruders from probing your network. For more
information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
9.5.3 How NAT Works
Each packet has two addresses – a source address and a destination address. For outgoing packets,
the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global
Address) is the source address on the WAN. For incoming packets, the ILA is the destination
address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local)
IP addresses to globally unique ones required for communication with hosts on other networks. It
replaces the original IP source address (and TCP or UDP source port numbers for Many-to-One and
Many-to-Many Overload NA T mapping) in each packet and then forwards it to the Internet. The LTE
Device keeps track of the original addresses and port numbers so incoming reply packets can have
their original values restored. The following figure illustrates this.

10.1 Overview
This chapter discusses how to configure your LTE Device to use 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 applications such as NetMeeting and CU-SeeMe).
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.
CHAPTER 10
Dynamic DNS
10.1.1 What You Need To Know
DYNDNS Wildcard
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.
If you have a private WAN IP address, then you cannot use Dynamic DNS.

Use the LTE Device firewall screens to enable and configure the firewall that protects your LTE
Device and network from attacks by hackers on the Internet and control access to it. By default the
firewall:
• Allows traffic that originates from your LAN computers to go to all other networks.
• Blocks traffic that originates on other networks from going to the LAN.
The following figure illustrates the default firewall action. User A can initiate an IM (Instant

Chapter 11 Firewall
11.1.2 What You Need to Know
DoS
Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the
Internet. Their goal is not to steal information, but to disable a device or network so users no longer
have access to network resources. The LTE Device is pre-configured to automatically detect and
thwart all known DoS attacks.
Firewall
The LTE Device’s firewall feature physically separates the LAN and the WAN and acts as a secure
gateway for all data passing between the networks.
It is designed to protect against Denial of Service (DoS) attacks when activated. The LTE Device's
purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet.
The LTE Device 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 LTE Device is installed betwe en the LAN and a broadband modem connecting to the Internet.
This allows it to act as a secure gateway for all data passing between the Internet and the LAN.
The LTE Device has one Ethernet WAN port and four Ethernet LAN ports, which are used to
physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the
broadband (cable or DSL) modem to the Internet.
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 W e b. Howev er, "inbound access" is not allowed (by default) unless the remote host
is authorized to use a specific service.
ICMP
Internet Control Message Protocol (ICMP) is a message control and error-reporting protocol
between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams,
but the messages are processed by the TCP/IP software and directly apparent to the application
user.
