LTE TDD B2268H User Guide

1 Introduction

Issue 01 (2014-01-15)

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 also 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 Introduction

1.2 Applications for the LTE Device

Here are some examples for which the LTE Device is well suited.

1.2.1 Internet Access

Your LTE Device provides Internet access by connecting to an LTE network wirelessly. Your LTE Device supports LTE frequency bands 38, 40, 42, and 43 although the bands it actually uses depends on your LTE service provider. Computers can connect to the LTE Device's

ETHERNET ports (or wirelessly).

Figure 1-1 LTE Device's Internet Access Application

1.2.2 VoIP Features

LTE TDD B2268H User Guide

1 Introduction

Issue 01 (2014-01-15)

VoIP is not supported

You can register one SIP (Session Initiation Protocol) profile with one account for that profile and use the LTE Device to make and receive VoIP telephone calls:

Figure 1-2 LTE Device's VoIP Application

The LTE Device sends your call to a VoIP service provider's SIP server which forwards your calls to either VoIP or PSTN phones. Enable the LTE Device's SIP ALG feature to support SIP phones and IAD devices on the LAN.

1.2.3 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 Device to access network resources. You can set up a wireless network with WPS (WiFi Protected Setup) or manually add a client to your wireless network.

LTE TDD B2268H User Guide

1 Introduction

Issue 01 (2014-01-15)

1.2.4 IPv6

Figure 1-3 Wireless Connection Application

IPv6 is not support

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

Step 1 Make sure the PWR/SYS LED is on (not blinking). Step 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.

----End

Activate WPS

Step 1 Make sure the PWR/SYS LED is on (not blinking). Step 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 for more information.

Issue 01 (2014-01-15)

1.4 Ways to Manage the LTE Device

Web Configurator 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. Keep in mind that backing up a configuration file will not back up passwords used to set up your VoIP account. Write down any information your ISP provides you.

1.6 LEDs (Lights)

The following graphic displays the labels of the LEDs.

Figure 1-4 LEDs on the top of the Device

Figure 1-5 LEDs on the Ethernet Ports

None of the LEDs are on if the LTE Device is not receiving power.

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 Wireless Network Overview

5 Wireless

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.

The following figure provides an example of a wireless network.

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

Figure 5-1 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.

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

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.

A channel is the radio frequencyused 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.

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.

5.1.2 Before You Begin

Before you start using these screens, ask yourself the following questions. See Section 5.7if 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.



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.

5.2 The Wireless General Screen

Use this screen to enable the Wireless LAN, enter the SSID and select the wireless security mode.

If you are configuring the LTE Device from a computer connected to the wireless LAN and you change the LTE Device's SSID or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the LTE Device's new settings.

Click Network Setting > Wireless to open the General screen. Select the Enable Wireless LAN checkbox to show the Wireless configurations.

5.2.1 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).

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.

DESCRIPTION

Security Mode

Choose Static WEP or Shared WEP from the drop-down list box.



Select Static WEP to have the LTE Device allow association with wireless clients that use Open System mode. Data transfer is encrypted as long as the wireless client has the correct WEP key for encryption. The LTE Device authenticates wireless clients using Shared Key mode that have the correct WEP key



Select Shared WEP to have the LTE Device authenticate only those wireless clients that use Shared Key mode and have the correct WEP key.

WEP Key

Enter a WEP key that will be used to encrypt data. Both the LTE Device and the wireless stations must use the same WEP key for data transmission.

5.2.2 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 LTE 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.

Encryption

If the security mode is WPA-PSK, the encryption mode is set to TKIP to enable Temporal Key Integrity Protocol (TKIP) security on your wireless network.

If the security mode is WPA-PSK2 and WPA-PSK Compatible is disabled, the encryption mode is set to AES to enable Advanced Encryption System (AES) security on your wireless network. AES provides superior security to TKIP.

If the security mode is WPA-PSK2 and WPA-PSK Compatible is enabled, the encryption mode is set to TKIPAES MIX to allow both TKIP and AES types of security in your wireless network.

5.2.3 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.

5.7 Technical Reference

This section discusses wireless LANs in depth.

5.7.1 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 WPA-PSK security 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 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.

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

5.7.2.1 SSID

Normally, the LTE Device acts like a beacon and regularly broadcasts the SSID 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.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 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.

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.

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.

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 for information about this.)

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

Figure 5-12 Types of Encryption for Each Type of Authentication

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 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.

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.

5.7.2 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.

5.7.3 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

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

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 5-13 Basic Service set

5.7.4 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 different 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.

5.7.5 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

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

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.

5.7.5.1 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.

Step 1 Ensure that the two devices you want to set up are within wireless range of one another.

Step 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).

Step 3 Press the button on one of the devices (it doesn't matter which). For the LTE Device you must press the WPS button for more than three seconds.

Step 4 Within two minutes, press the button on the other device. The registrar sends the network name (SSID) and security key through a 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.

5.7.5.2 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, you must enter the PIN from one device (usually the wireless client) into the second device (usually the Access Point or wireless router). Then, when WPS is activated 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.

Step 1 Ensure WPS is enabled on both devices. Step 2 Access the WPS section of the AP's configuration interface. See the device's User's Guide for

how to do this.

Step 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 ).

Step 4 Enter the client's PIN in the AP's configuration interface.

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

Step 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.

Step 6 Start WPS on both devices within two minutes. Step 7 Use the configuration utility to activate WPS, not the push-button on the device itself. Step 8 On a computer connected to the wireless client, try to connect to the Internet. If you can connect,

WPS was successful.

----End

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.

The following figure shows a WPS-enabled wireless client (installed in a notebook computer) connecting to the WPS-enabled AP via the PIN method.

Figure 5-14 Example WPS Process: PIN Method

5.7.5.3 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.

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

Figure 5-15 Example WPS Process: PIN Method

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 device 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.

5.7.5.4 Example WPS Network Setup

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.

LTE TDD B2268H User Guide

5 Wireless

Issue 01 (2014-01-15)

Figure 5-16 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.

Figure 5-17 WPS: Example Network Step 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.

5.7.5.5 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 preshared 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).



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

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.

6 Home Networking

6.1.1 What You Need To Know

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

6.1.1.1 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.

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.

LTE TDD B2268H User Guide

6 Home Networking

Issue 01 (2014-01-15)

DHCP

DHCP (Dynamic Host Configuration Protocol) allows clients to obtain TCP/IP configuration at start-up 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.

6.1.1.2 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 configuration 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.

6.2 The LAN Setup Screen

Click Network Setting > Home Networking to open the LAN Setup screen. Use this screen to set the Local Area Network IP address and subnet mask of your LTE Device and configure the DNS server information that the LTE Device sends to the DHCP client devices on the LAN.

7 Routing

Issue 01 (2014-01-15)

7.1 Overview

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 LTE Device routes most traffic from A to the Internet through the LTE Device's default gateway (R1). You create one static route to connect to services offered by your ISP behind router R2. You create another static route to communicate with a separate network behind a router R3 connected to the LAN.

8 Network Address Translation (NAT)

Issue 01 (2014-01-15)

8 Network Address Translation (NAT)

8.1 Overview

NAT (Network Address Translation - NAT, 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.

8.1.1 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 for advanced technical information on NAT.

LTE TDD B2268H User Guide

8 Network Address Translation (NAT)

Issue 01 (2014-01-15)

8.2 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 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. You can allocate a server IP address that corresponds to a port or a range of ports.

Please refer to RFC 1700 for further information about port numbers.

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, refer 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.

8.5 The ALG Screen

Use the ALG screen to enable or disable SIP Application Layer Gateway (ALG) on the LTE Device. Click Apply to save your change.

The SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses embedded in the data stream. When the LTE Device registers with the SIP register server, the SIP ALG translates the LTE Device's private IP address inside the SIP data stream to a public IP address. You do not need to use STUN or an outbound proxy if you enable the SIP ALG.

For the LTE environment, the LTE interface may experience heavy overhead when sending SIP re-registration requests due to SIP server NAT session timeout. This default NAT session timeout value (3600 seconds) helps to decrease the chance of this happening.

8.6.1 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.

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 8-5 NAT Definitions

NAT never changes the IP address (either local or global) of an outside host.

8.6.2 What NAT Does

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).

8.6.3 How NAT Works[h1]

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 NAT 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.

9 Dynamic DNS

Issue 01 (2014-01-15)

9.1 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.

9 Dynamic DNS

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.

9.1.1 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.

longer have access to network resources. The LTE Device is pre-configured to automatically detect and thwart all known DoS attacks.

The LTE Device's firewall feature physically separates the LAN/WLAN 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 between the LAN/WLAN 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 Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service.

Enabling the firewall may impact the system performance.

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.

10.6 Firewall Technical Reference

This section provides some technical background information about the topics covered in this chapter.

10.6.1 Guidelines For Enhancing Security With Your Firewall

Step 1 Change the default password via web configurator. Step 2 Think about access control before you connect to the network in any way.

LTE TDD B2268H User Guide

10 Firewall

Issue 01 (2014-01-15)

Step 3 Limit who can access your LTE Device. Step 4 Don't enable any local service (such as Telnet or FTP) that you don't use. Any enabled service

could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network.

Step 5 For local services that are enabled, protect against misuse. Protect by configuring the services to

communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces.

Step 6 Keep the firewall in a secured (locked) room.

----End

10.6.2 Security Considerations

Incorrectly configuring the firewall may block valid access or introduce security risks to the LTE Device and your protected network. Use caution when creating or deleting firewall rules and test your rules after you configure them.

Consider these security ramifications before creating a rule:

Step 1 Does this rule stop LAN users from accessing critical resources on the Internet? For example, if

IRC is blocked, are there users that require this service?

Step 2 Is it possible to modify the rule to be more specific? For example, if IRC is blocked for all users,

will a rule that blocks just certain users be more effective?

Step 3 Does a rule that allows Internet users access to resources on the LAN create security

vulnerability? For example, if FTP ports (TCP 20, 21) are allowed from the Internet to the LAN, Internet users may be able to connect to computers with running FTP servers.

Step 4 Does this rule conflict with any existing rules?

----End

Once these questions have been answered, adding rules is simply a matter of entering the information into the correct fields in the web configurator screens.

VoIP is not supported

13 VoIP

13.1 Overview

Use this chapter to:



Connect an analog phone to the LTE Device.



Make phone calls over the Internet, as well as the regular phone network.



Configure settings such as speed dial.



Configure network settings to optimize the voice quality of your phone calls.

13.1.1 What You Need to Know

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

VoIP

VoIP stands for Voice over IP. IP is the Internet Protocol, which is the message-carrying standard the Internet runs on. So, Voice over IP is the sending of voice signals (speech) over the Internet (or another network that uses the Internet Protocol).

SIP

SIP stands for Session Initiation Protocol. SIP is a signaling standard that lets one network device (like a computer or the LTE Device) send messages to another. In VoIP, these messages are about phone calls over the network. For example, when you dial a number on your LTE

LTE TDD B2268H User Guide

13 VoIP

Issue 01 (2014-01-15)

Device, it sends a SIP message over the network asking the other device (the number you dialed) to take part in the call.

SIP Accounts

A SIP account is a type of VoIP account. It is an arrangement with a service provider that lets you make phone calls over the Internet. When you set the LTE Device to use your SIP account to make calls, the LTE Device is able to send all the information about the phone call to your service provider on the Internet.

Strictly speaking, you don't need a SIP account. It is possible for one SIP device (like the LTE Device) to call another without involving a SIP service provider. However, the networking difficulties involved in doing this make it impractical under normal circumstances. Your SIP account provider removes these difficulties by taking care of the call routing and setup figuring out how to get your call to the right place in a way that you and the other person can talk to one another.

Voice Activity Detection/Silence Suppression

Voice Activity Detection (VAD) detects whether or not speech is present. This lets the LTE Device reduce the bandwidth that a call uses by not transmitting "silent packets" when you are not speaking.

Comfort Noise Generation

When using VAD, the LTE Device generates comfort noise when the other party is not speaking. The comfort noise lets you know that the line is still connected as total silence could easily be mistaken for a lost connection.

Echo Cancellation

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

Use this screen to maintain basic information about each SIP account. You can also enable and disable each SIP account, configure the volume, echo cancellation and VAD (Voice Activity Detection) settings for each individual phone port on the LTE Device.

How to Find Out More

See Section 16.6 for advanced technical information on SIP.

13.1.2 Before You Begin



Before you can use these screens, you need to have a VoIP account already set up. If you don't have one yet, you can sign up with a VoIP service provider over the Internet.



You should have the information your VoIP service provider gave you ready, before you start to configure the LTE Device.
