Some basic points to understand:

DIRECWAY(r) FAIR ACCESS POLICY

To ensure equal Internet access for all DIRECWAY subscribers,

Hughes Network Systems maintains a running average fair access policy. Fair access establishes an equitable balance in Internet access across Internet services by service plan for all

DIRECWAY customers regardless of their frequency of use or volume of traffic. To ensure this equity, customers may experience some temporary throughput limitations. DIRECWAY

Internet access is not guaranteed. This policy applies to all service plans including "Unlimited" plans where customers' use of the service is not limited to a specific number of hours per month. To learn more about HNS' Fair Access Policy, please see the

DIRECWAY Web site

A. WHO MAY USE THE SERVICE -- SUPERVISION.

Using the Service requires that you be a Subscriber of the

Service, or that you have permission of a Subscriber to use that

Subscriber's DIRECWAY access account. Even if you are not yourself a Subscriber, you still must comply with these terms if you use the Service. Subscriber agrees to supervise and be fully responsible for all use by others of the Subscriber's DIRECWAY account in accordance with the terms and conditions of this

Agreement as more fully described below.

B. ABOUT DIRECWAY SUBSCRIBERSHIP AND

ACCOUNTS.

A "Subscriber" is a person who, being at least 18 years of age, has agreed to this Business Edition Subscriber Agreement, is legally able to enter into contracts on behalf of him or herself, and/or on behalf of his or her employer and whose name and other necessary billing and identifying information are reflected on

HNS' records as the person responsible for a particular

DIRECWAY account. This DIRECWAY Business Edition

License is a non-exclusive, non-assignable, and non-transferable license to use the DIRECWAY Service as described in any of the

DIRECWAY Business Edition services plans as set forth in the

DIRECWAY Web site. A DIRECWAY account is required for access to the Service and is recognized by HNS by the

Subscribers associated account number, billing information and

Subscriber name.

C. PRICING AND BILLING DETAILS.

Please pay close attention to the terms referred to below regarding pricing and billing information. Some of these terms are located in a separate document on Service and are an important part of this Agreement -- they may be contained in a separate document

(or documents), hereby incorporated by reference, as they contain pricing and billing options and plans that you may choose from or that may not apply to or be available to every Subscriber.

D. CHANGES.

Changes to both the Service and this Agreement may be made from time to time in HNS' sole discretion. These changes may affect your rights and obligations under this Agreement and may also affect the makeup and nature of the Service itself. This

Agreement, including any future modifications, will be available on the DIRECWAY Web site at http://www.DIRECWAY.com/about/agreement.html.

E. YOUR RIGHT TO CANCEL.

In the event that HNS makes any material changes to the Service which significantly adversely affect performance, then the

Service by Subscriber or by users of Subscriber's account.

•

1032564-0001 Revision A

sufficient notice for all purposes as to charges incurred and paid or to be paid to HNS. Additional terms relating to pricing, billing and payment and which are an integral part of this Agreement are set forth and available on the DIRECWAY Web site.

4.2 PAYMENT

HNS will make available to you a statement for each billing cycle showing payments, credit purchases and other charges. Payment of the outstanding balance is due in full each month. If your payment is not received by HNS before the next statement is issued, you may be charged interest on the delinquent balance at the rate of one and one-half percent (1.5%) per month, prorated on a daily basis. Furthermore, if we do not receive payment from you before your next statement is issued, HNS has the right to deactivate your service upon the expiration of any applicable grace period with respect to the amount due.

4.3 COMMENCEMENT AND DURATION OF

SUBSCRIBERSHIP FEES.

Subscriber acknowledges that (subject to any exceptions granted by HNS) a monthly subscribership fee will apply for each and every month (or portion thereof) that one is a Subscriber.

Subscriber's account will continue until Subscriber cancels the account in accordance with the method or methods specified by

HNS (unless otherwise terminated in accordance with this

Agreement). As stated above, Subscriber may be subject to cancellation by the Subscriber, subject to the cancellation fee, if applicable. The monthly subscription fee shall cease to apply for any months after the billing month in which Subscriber cancels or terminates its account in accordance with the terms and conditions stated herein. HNS may, but is not required to, accept partial payments from you. If partial payments are made, they will be applied to statements starting with the oldest outstanding statement. Late fees will be assessed monthly as allowed by applicable law until the total outstanding account balance, including late fees and all other charges, are paid. If you send us checks or money orders marked "payment in full" or otherwise labeled with restrictive endorsements, HNS can, but is not required to, accept them, without losing any of our rights to collect all amounts owed by you under this Agreement. In the case of late payment or non-payment for any of the

DIRECWAY(r) Services ordered by you or any of the charges stated herein, you understand and agree that HNS may report such late payment or non-payment to the appropriate credit reporting agencies. If HNS chooses to use any collection agency or attorney to collect money that you owe HNS or to assert any other right which HNS may have against you, you agree to pay the reasonable costs of collection or other action including, but not limited to, the costs of a collection agency, reasonable attorney's fees, and court costs, as provided by applicable law.

4.4 REACTIVATION

If your service is inactivated because you did not submit payment on time or for any other reason, in addition to payment of past due amounts, HNS may require a deposit before reactivating your

HNS service, which shall not exceed one (1) year subscription fees. Amounts deposited by you will appear on your statement as a credit, and service charges and other fees will be invoiced as set forth above. Any unpaid amounts will be deducted each billing cycle from the credit amount. Credit amounts shall not earn or accrue interest. If your DIRECWAY(r) Service is inactivated for any reason, including at your request or because of your failure to pay past due amounts, and you want to reactivate the service, you agree to pay a reactivation fee in accordance with HNS' then current rates. In addition you must bring your account up to date by making payment in full of any outstanding balance, fees and charges.

4.5 ANCILLARY EQUIPMENT, SERVICES.

DW4020 installation and components

1

Congratulations on your purchase of a DIRECWAY

®

DW4020! Once your unit has been professionally installed, you will be able to click on a browser and surf the Internet. You will also be able to operate a local area network (LAN), after you configure your computers with network interface cards (NICs), connect them with Ethernet cable, and configure your computers’ operating system network properties.

The DW4020 User Interface provides system information, such as your

Gateway IP (Internet protocol) address and subnet mask, that is necessary for configuring your network. It also provides help files and a firewall. It is explained in Chapter 2.

Contact information

Should you have questions about your installation or DW4020, contact your service provider.

System requirements

Please verify that your computer system meets the following requirements before proceeding.

•

Ethernet interface installed on at least one computer. See Chapter 3 for information about configuring Windows network settings.

•

Analog telephone line (for system installation).

Note:

This manual documents configuring Windows network settings for the

DW4020. The DW4020 can also be used with Macs, Unix, Linux, or other operating systems.

Before the installer leaves

Before the installer leaves, make sure:

•

The installer has provided your site ID, Gateway IP address, and subnet mask, and that these are written in the spaces provided on the cover of this manual. You must record this information so it is available in case the

DW4020 is not functioning and you cannot access it. You need the site ID when you communicate with technical support. You need the Gateway IP address and subnet mask to configure your operating system network properties. Read Chapter 3 to learn how these are used.

•

The installer has clearly labeled the receive modem coaxial cable and the transmit modem coaxial cable. See Chapter 7 for diagrams that show where these cables attach to the DW4020.

•

Verify that your DW4020 is operating correctly by surfing the Internet.

Launch a browser and surf to a known Web site, such as Yahoo, CNN.com, or some Web site you regularly visit. If you can surf the Internet, your

DW4020 is working properly.

DW4020 installation and components

Installation, your service offering, and recording the site ID,

Gateway IP address, and subnet mask

During the installation process, the installer will ask you to complete some subscription screens. These are shown below.

As you complete them, confirm that the service offering you choose shows the correct information for:

•

Network Address Translation (NAT) - enabled or disabled

•

Dynamic Host Configuration Protocol (DHCP) - enabled or disabled

•

Number of e-mail accounts

All of these things, along with the Gateway IP address and subnet mask, affect how you configure your operating system network properties. Read Chapter 3 to learn more.

If you need more information about your service offering, refer to the materials you have already received regarding your service offering, or reviewed when you placed your order. If you have further questions, call your service provider.

In addition, the final screen will show your site ID, Gateway IP address, and subnet mask. Record these on the cover of this manual.

The subscriber agreement

The first screen you will see is the subscriber agreement. You will be asked to click

OK

to approve it.

Figure 5: The DW4020

Your DW4020 was completely assembled by the professional installer. Should you need to move it to another location, you would not have to disassemble it.

You would simply disconnect the receive, transmit, and Ethernet cables and unplug it from the wall outlet or surge protector. Cabling and assembly instructions have been provided in

Assembling the DW4020 on

page 61 should you ever need them.

CAUTION

• Keep the DW4020 in a well-ventilated space. Do not place anything on top of the receive modem. Doing so may reduce heat dissipation and cause operational problems or damage the unit.

• Do not install near any heat sources, such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

• Never unplug the power cord from the receive modem or the Gateway while the DW4020 is powered on. Always disconnect the power cord from the wall outlet or surge protector.

How the DW4020 works

The DW4020, in combination with an antenna, provides satellite connectivity for multiple computers on a LAN. Because the software is on the Gateway, there is no need to load any other software on your computer.

Figure 1 shows how the DW4020 receives and transmits satellite signals. The

DW4020 is independent of operating platforms. Whether your computers use

Windows, Unix, Linux, or is a Mac, they can surf the Internet now that they are connected to the DW4020. The DW4020 can also be used with devices other than computers, such as point-of-sale (POS) terminals or credit verification devices.

•

Transmit Status - indicates the status of the transmit modem.

•

Receive Status - indicates the status of the receive modem.

•

Software Download Status - indicates the status of the downloading of software from the Network Operations Center (NOC). If the DW4020 has been commissioned, this message will generally indicate that software download has been completed. Occasional updates are automatically downloaded to the DW4020 from the NOC. The purpose of these updates is to enhance DW4020 performance. Remember that this software is not placed on your computer, but on the DW4020. No action is required from you. The software version number in the

System Information

page indicates the current version of the downloaded software. See

System Information

on page 18.

If there is a problem with any of these four status elements, a red exclamation mark will appear in the status field. In addition, if there is a problem with the

Transmit Status

or

Receive Status

, an error message and an error code will appear in blue. You can click on the error message and an explanation of the error condition and what action might solve it will appear. See Figure 10. The tables below provide a more detailed explanation of status codes, error messages, and corrective actions.

Figure 10: On-line help for status messages

Transmit Status messages

The following messages may appear in the Transmit Status field. The

Comments section gives more information about each code, and describes any possible corrective measures. See Figure 11 on page 15 for corrective measure involving cables or the power supply.

Power cycling

means to unplug the power cord from the wall outlet or surge protector, wait 10 seconds, and plug it back in.


11

If corrective measures do not solve a problem, contact your service provider.

TxCode 8 means the transmit modem is working properly. It is the code you will see most of the time.

Note:

Remember that IRU refers to the receive modem, and that ITU refers to the transmit modem.

Table 4: Transmit status (TxCode) messages and corrective actions

Message Displayed Comments Numeric

TxCode

0 The transmitter is not connected to the receiver

This status will occur only if the Indoor Transmit Unit (ITU) is not connected to the Indoor Receive Unit (IRU). It can result for the following reasons:

1

2

3

4

5

6

The transmitter has been disabled by the Network

Operations Center

The transmitter has been placed in test mode by the

Network Operations Center

The transmitter is locking to the receive carrier

The transmitter is not responding to commands sent from the receiver

• The 25-pin parallel cable is not properly connected to the Indoor Receive Unit or Indoor Transmit Unit: Check the cable and make sure the ends are securely fastened.

• Indoor Transmit Unit failure. The Indoor Transmit Unit has failed and may need to be replaced.

This condition occurs when the transmitter is not enabled. A transmitter may be disabled for short periods of time by the NOC for service or troubleshooting. It may also be disabled if the user discontinues the satellite service. If this condition persists, it can only be corrected by requesting that the unit be enabled.

This status requires no user action and this test usually completes in 15 minutes or less. This condition occurs when the NOC places the transmitter into special transmission modes to measure the performance of the transmitter. When in this mode, the unit is unable to transmit normal user data to the NOC.

This condition occurs during initial startup or when the receiver is locking to the receive signal. It is normal for this condition to persist for up to 10 seconds. If this condition persists for more than 10 seconds, try disconnecting and reconnecting the receiver coaxial cable and wait 10 seconds. If the situation still persists, then the

Indoor Transmit Unit may need to be replaced.

This condition indicates that something is not operating properly in the

Receive/Transmit Unit configuration. Perform the following actions to attempt to recover from this condition:

• Verify that the Indoor Receive and Transmit Units are securely connected with a 25-pin parallel cable.

• Reset the IRU by unplugging the IRU power cord from the wall socket and then plugging the power cord back into the wall socket. This will reset the Indoor

Receive and Transmit Units.

The transmitter is not locked to the network timing

The transmitter is not available because the receiver is not detecting a signal or is not locked to the correct network

This condition could also be caused if the power supply is faulty. If this condition cannot be resolved by following the steps listed above, then you may need to replace the power supply, the Receive/Transmit unit cable and/or the Transmit

Unit.

No action is necessary if this condition occurs from time to time and quickly resolves itself. If this issue persists, it is likely due to a NOC-related service issue. The condition may also be due to Indoor Transmit Unit failure; in rare cases, the Transmit unit may fail and may have to be replaced.

Check your receive signal. This condition occurs when the Indoor Receive Unit is not receiving a good signal. The receiver must be locked to the correct network in order for the transmitter to operate. If your receiver is not locked (no signal) or is locked to the wrong network, the transmitter is unable to transmit data. Please verify that you have a good signal strength by going to the Receive Statistics page. This could also be caused by inclement weather.

The transmitter is not available because the satellite receiver is not tuned for normal operation

The transmitter is available

This condition occurs when the transmitter is disabled for safety reasons. If this happens during installation or commissioning, the installer will close the Antenna

Pointing program and resolve the condition.

The transmitter is adjusting for optimal network timing

The transmitter is unable to communicate with the Network

Operations Center

The transmitter is not available because the receiver software is out of date

This is the normal operational state and indicates that the transmitter is ready to transmit data.

This condition typically occurs when your DW4020 is first commissioned or the first time it is used for data traffic. This must occur before the Indoor Transmit

Unit is able to transmit successfully. Typically, this process usually takes less than a minute.

This condition indicates that the unit has stopped attempting to transmit user data because there were a number of failures in sending data to the NOC over the satellite link. This could be the result of weather conditions causing lost packets or return channel equipment failures in the NOC.

This condition indicates that the installed software version is not recent enough to operate on the network. New software will be required from time to time due to network infrastructure and capability upgrades and in order to maintain network efficiency and fix any known problems.The system will automatically update your software version to ensure that you can enjoy uninterrupted operation. If you do not use the DW4020 for a long period of time and miss the updates, you may need to contact Customer Care.

The transmitter is not receiving network control messages from the Network

Operations Center

This condition indicates a NOC equipment outage. This may be a transient condition and the system should recover automatically.

The transmitter is unable to range because it cannot communicate with the

Network Operations Center

The transmitter is not available because ranging has failed

The transmitter is waiting for a ranging request to be processed by the Network

Operations Center

Ranging is the process that adjusts your satellite transmitter timing and power. Your satellite transmitter conducts ranging as needed to ensure that it can communicate successfully with the Network Operations

Center.This condition can indicate any of the following:

• The NOC is not receiving ranging information from the transmitter. This may indicate a transmit problem at the NOC. This should get cleared in a few minutes.

• The transmitter is unable to achieve enough transmit power to send ranging information to the NOC. Make sure that the power supply is correct. The power supply should be Part #1031105-0001.

• The transmitter is sending incorrect timing data because the wrong zip code or latitude/longitude information was entered during installation.

• The outdoor transmitter unit (ODU)--that is, the antenna--is not operating properly or is not properly connected to the ITU. Please ensure that the transmit cable is securely fastened to the Transmit Unit.

This condition indicates that the transmitter is not operational because ranging has failed. Ranging is the process that adjusts your satellite transmitter timing and power. Your satellite transmitter conducts ranging as needed to ensure that it can communicate successfully with the Network Operations Center. The ranging failure may happen due to the antenna becoming misaligned or if repeated attempts to range do not succeed. This condition may also be caused due to adverse weather conditions. In rare cases, this may also indicate NOC issues but should clear within a few minutes.If your system was operational in the past and you see these messages repeatedly, you can try to force range by performing the Connectivity Test.

This condition occurs if the system is busy adjusting power and timing for other users. This process may take up to a minute or more.

The transmitter is waiting for a transmit request to be processed by the Network

Operations Center

The satellite transmitter is unable to obtain an available transmission rate

The transmitter is requesting a transmit pointing test

This condition occurs when the system is unable to provide transmit bandwidth.

This occurs when many users sign-on simultaneously. It should clear in a few minutes automatically.

This condition occurs if the transmitter cannot successfully range. Ranging is the process that adjusts your satellite transmitter timing and power. Your satellite transmitter conducts ranging as needed to ensure that it can communicate successfully with the Network Operation Center. A possible cause is that the transmitter could not achieve enough power to transmit. This is likely caused because the antenna is not accurately pointed. However, it may also be a transmitter power problem. Check the power supply and make sure that it is Part

# 1031105-0001.

This condition can occur during installation when the Antenna Pointing program on the installation computer requests that the transmitter perform a transmit pointing test. This condition persists until the NOC responds that the transmitter is either actively performing the pointing test or is queued to perform the test when test resources become available in the NOC. This is a normal condition for initial installation. The transmitter may also periodically go into this condition for short periods of time (less than 5 seconds) to perform periodic transmit pointing tests. These periodic tests are performed to ensure that the antenna is pointed accurately.

The transmitter is queued for a transmit pointing test

This condition can occur during installation when the Antenna Pointing software on the installation computer requests a transmit pointing test and the NOC has responded that the transmitter is queued for the next available test time. It may also occur when the transmitter is performing periodic background transmit pointing tests at the same time that other users on the network have requested tests. This is a normal state after initial installation.

The transmitter is performing a transmit pointing test

The transmitter is disabled because a transmit pointing test failed

This condition occurs when one of the following tests are active:

• During installation, the Antenna Pointing software requests that the transmitter perform a transmit pointing test. This condition will persist until the Antenna

Pointing software exits from the transmit pointing test mode.

• The DW4020 performs a periodic background transmit pointing test to make sure that the antenna is still pointed correctly. This periodic test takes less than

5 seconds.

If the problem persists, try power-cycling the DW4020 by unplugging the wall outlet and plugging it back in.

This condition occurs when the transmitter fails a transmit pointing test. This indicates that the transmitter did not meet the minimum specifications required.

This is likely due to an antenna installation problem. The antenna installer needs to fine-point the antenna. The transmitter will not transmit until the transmit pointing test passes.

The transmitter is disabled pending a transmit pointing test

The transmitter is disabled because a transmit pointing test cannot be performed

This condition occurs when the transmitter is required to perform a periodic background transmit pointing test, but has not been able to perform the test within the time window required. The transmitter is expected to be in this condition for no more than two minutes at random periodic intervals. This condition can also occur after the transmitter is first powered on after it has been powered off for more than a day. If the unit remains in this condition for more than two minutes, then the automated transmit pointing components in the NOC are likely experiencing problems. This condition should clear in a few minutes.

This condition occurs when the transmitter cannot perform the transmit pointing test when initially installed or when the transmitter is required to range. The condition indicates that the NOC components needed to perform the transmit pointing test are not operational.

The receiver is not connected

The receiver is in pointing mode

The receiver is in factory or NOC mode

Please make sure that the Indoor Receive Unit is connected to the

Gateway via the USB cable. If the cable is connected and you still see this message, use the following steps for troubleshooting:

• Make sure the power supply is correct. The power supply should be Part # 1031105-0001.

• Try power-cycling the DW4020 by unplugging the power cord from the wall outlet and then plugging it back in.

• Try using a different USB cable.

• If none of the above resolve the issue, you may need to replace the Indoor Receive Unit.

This condition indicates that the installer is performing antenna pointing. In this mode, the transmitter is disabled for safety reasons since the installer is working near the dish. If this occurs during normal operation, try power-cycling the DW4020 by unplugging the power cord from the wall outlet and then plugging it back in.

This status is for DW4020 testing purposes only. You should never see it. If this occurs during normal operation, try power-cycling the

DW4020 by unplugging the power cord from the wall outlet and then plugging it back in.

The receiver is not locked to a signal If the DW4020 had been operating previously, this status is probably due to inclement weather conditions and will be corrected when the weather improves. This condition can also indicate that the IRU is unable to receive the signal from the NOC.

This is also associated with a signal level less than 30. This occurs if there is a weather outage at the user location, a NOC outage due to inclement weather or other reasons, a misaligned or faulty antenna, or faulty cabling. If this keeps happening under normal weather conditions, make sure the power supply is correct.

The power supply should be Part # 1031105-0001. If the power supply is correct, try power-cycling the DW4020 by unplugging the power cord from the wall outlet and then plugging it back in.

The receiver is locked to the wrong network This condition should only be seen during installation and occurs when the receiver is locked to a signal, but the signal ID does not match the ID that was assigned to the user during commissioning or the ID that was entered by the installer during manual pointing.

If this occurs during normal operation, it may be due to the user changing acquisition parameters, including frequency and/or location of satellite, or the antenna becoming misaligned.

The receiver is operational

The receiver is not detecting a signal

The receiver is locked to an unknown network

This is the normal operating state where the receiver is receiving data from the NOC. Only when the receiver is in this state will the transmitter operate correctly.

This condition occurs when the IRU is not detecting any type of radio signal from the antenna. This could indicate that the cabling between the receiver and the antenna is faulty or that the receiver itself is faulty. Check that the cables are firmly connected on the

DW4020. Also, make sure that the power supply is correct. The power supply should be Part # 1031105-0001. Try power-cycling the DW4020 by unplugging the power cord from the wall outlet and then plugging it back in.

This condition should only be seen during installation and occurs when the receiver is locked to a signal but there is no DIRECWAY

Network ID on that signal. If this occurs during pointing or commissioning, the antenna has not been pointed correctly. If it occurs during normal operation, it may be due to the user changing acquisition parameters, including frequency and/or location of satellite, or the antenna becoming misaligned. The former condition can be corrected by re-commissioning the site.

The latter requires an antenna repointing.

This chapter explains how to configure your network settings and e-mail.

•

If DHCP is not enabled on your DW4020 system, you have been assigned a static IP address. If DHCP is not enabled on your DW4020 system, you need to set up IP addresses manually on each computer connected to the

DW4020. This is also referred to as static configuration since the computer's

IP address remains the same across restarts. Follow the instructions in

Configuring a DW4020 with a static IP address

.

•

If DHCP has been enabled, follow the instructions in

Configuring with

DHCP enabled

on page 32.

•

To configure your e-mail, follow the instructions in

Configuring

DIRECWAY® e-mail

on page 38.

To activate the e-mail accounts provided in your service agreement, go to myDIRECWAY.com. If you purchased your DIRECWAY system through one of our Value Added Resellers, please contact your provider to establish your e-mail accounts.

You must have already installed network interface cards (NICs) in the computers that will be on your local area network (LAN), and connected the computers with Ethernet cable to the DW4020.

Note:

Remember you must carry out the relevant instructions for

each

of the computers or other devices on your LAN that you want to have access to the

Internet.

Configuring a

DW4020 with a static

IP address

The instructions for configuring a Windows 98SE, ME, 2000, or XP system with a static IP address vary slightly. Find the appropriate instructions for your system and follow them.

As you manually configure the client computers you will enter:

•

IP Address.

You need a valid IP address for each computer. Make sure the address does not conflict with any other computer connected to the

DW4020. You can obtain the entire list of available addresses for use with your DW4020 from the "FAQ" section of the DW4020 User Interface.

•

Subnet Mask.

This is the subnet mask assigned to your DW4020. It is available on the System Information page of the User Interface. You would also have written this on the front of this manual during registration.

•

Default Gateway.

This is the IP address of the Gateway and is also available on the System Information page of the User Interface. You would have also written this on the front of this manual at the end of registration.

Overview

Configuring the Firewall

4

The DW4020 has the capability to "drop" or block certain kinds of IP packets from reaching your local area network (LAN) from the Internet. This can help protect the computer(s) on your LAN from receiving undesired or harmful traffic via the Internet. You can enhance your protection further by installing commercial firewall software on each of the computers on your LAN.

Note:

It is important to remember that the firewall checks

inbound packets only.

If you want to check outbound packets, you must obtain another firewall and install it on the network or on selected hosts on the network.

If you have a service offering that configures your DW4020 for Network

Address and Port Translation (NAPT), a variation of Network Address

Translation (NAT), you may not want to use the firewall feature. NAPT translates the source and destination IP addresses in packets so that the DW4020 can look like a single computer with a single address on the Internet side but use multiple IP addresses to access the individual computers on your LAN. NAPT by itself gives some protection from unwanted traffic from reaching computers on your LAN.

Some service offerings provide "public" IP addresses that the DW4020 passes through to and from the Internet without address translation. In this case you would probably want to enable the DW4020's firewall since your LAN computers are directly accessible by computers on the Internet. You may also want the additional protection that commercial firewall software offers.

If you enable the DW4020's firewall, you can block incoming packets which meet certain "rules" that you can configure through the DW4020's User

Interface. However, the firewall can't be used to filter traffic that is going to the

Internet. So it's not possible to restrict access to the Internet to only certain computers on your LAN or to enforce parental controls.

Note:

You can only connect from a computer on your LAN to a computer on the

Internet using a Virtual Private Network (VPN) if you are configured to use public addresses (not NAPT). Also, you cannot enable the DW4020's firewall function if you want to make VPN connections from any of the computers on your LAN.

Firewall

Configuration

To configure the firewall, you can define up to 10 "rules" using the

Firewall

Configuration

screen on the User Interface in the DW4020. If the control information in an incoming packet matches

any

of the defined rules, the

DW4020

drops

the packet. So a packet will be passed from the Internet through the DW4020 to the LAN, and thus to your computers, only if the packet doesn't match any of the rules that you have defined. If you haven't defined any rules, all packets will be passed through the firewall.

Configuring rules

Note that the rules that you configure apply to all traffic bound for

any

of your

LAN computers. This means that you can't block certain kinds of traffic (for example, a "ping" from another computer trying to see if it can establish a connection) from reaching some of your computers without blocking that kind of traffic to all of your computers. To configure the firewall, follow the steps below.

1. Access the

User Interface

and click on

Firewall Configuration

. The screen in Figure 44 appears.

Figure 44: Firewall Configuration screen

2. Check the

Enable Firewall box.

The firewall starts (as shown in the figure) with no rules defined. Each rule requires that you specify four fields. If the DW4020 firewall is enabled it will check the fields specified in each IP packet that comes in from the

Internet bound for your LAN to see if they match any of the rules that you have defined. If there is a match for all fields with any of the rules that you have defined, the firewall won't deliver the packet to the LAN. The fields to be specified for each rule definition are:


47

a.

Port Number or Protocol ID.

Use the drop down menu to specify that one or the other of these fields be checked for each rule that you define. See below for more information on the standard Internet values used for port numbers and protocol IDs.

–

Destination Port Number.

This field specifies the particular application, such as Domain Name Server (DNS), Web Server, or File Transfer

Protocol (FTP) that the incoming packet is trying to reach.

–

Protocol ID.

This field specifies the type of Internet Protocol, such as

TCP (Transmission Control Protocol (TCP) or User Datagram Protocol

(UDP), that the packet is using.

b.

Port/Protocol Number.

This number describes the specific Destination

Port number(s) or Protocol ID(s) to be blocked. You may specify up to five numbers in this field with commas separating the numbers.

c.

Source IP Address.

This is the IP address of the device from which the inbound packet came.

d.

Subnet Mask.

This mask is applied to the source IP Address in the incoming packet to determine how many bits in the source IP Address field are to be check against the source IP address that you specified in the current rule. If you specify 255.255.255.255 for the subnet mask, all source IP address bits in the incoming packet will be checked against all source IP address bits specified in the rule. You would enter the

255.255.255.255 subnet mask if you wanted the rule to block certain traffic that originated from one specific IP address - usually one specific computer. You might specify a subnet mask of 255.255.255.0 in a rule if you want the rule to apply to all source IP address bits in a rule except the lower 8 bits. This allows you to block packets from a range of IP addresses (usually a network or subnet) using a single rule.

Deleting rules

1. To delete a rule that was previously defined, enter

0

in the

Port/Protocol

Number

field.

2. Enter

0.0.0.0

in the Source IP Address field.

3. Enter

255.255.255.255

in the Subnet Mask field.

4. Select the

Save Configuration

button.

Port Numbers and

Protocol IDs

The Internet Assigned Numbers Authority (IANA) maintains the official list of

Port Numbers and Protocol IDs used on the Internet. You can see this list at: http://www.iana.org/numbers.html.

Some common port numbers that you might want to use in firewall rules are shown in Table 1. Some common protocol IDs are shown in Table 2.

Sample Firewall

Configuration

Figure 2 shows a sample firewall configuration. This single rule blocks all incoming File Transfer Protocol (FTP), Telnet, and Domain Name Server

(DNS) requests that originate from any IP address. These protocols are some of the most common ones used to attack computers on the Internet. This rule will

not

block FTP sessions, Telnet sessions, or DNS requests (and corresponding responses) that originate from computers on your LAN through the DW4020 to the Internet.

Figure 45: Sample firewall configuration

Configurations that may cause problems

The capability to block incoming packets by protocol ID would typically be used only in conjunction with specific source IP addresses or ranges of addresses. Table 3 shows some of the consequences of blocking packets from all source IP addresses for several common protocol IDs.

Therefore, if you choose to block incoming packets by protocol ID, be very careful to specify source IP Address ranges that you are sure that you will not need to access. using the specified protocol ID.

The DW4020 is extremely reliable. If you find you cannot surf the Internet or the DW4020 seems to have a problem, follow this sequence of steps below to identify and fix the problem.

•

Check whether the DW4020 LEDs or on or off.

The LEDs may indicate that a connection has become loose. Reconnecting a cable or power cord may restore function. See

DW4020 LEDs status

.

•

Check if the LEDs are blinking in a pattern.

The LEDs can blink in a pattern. The patterns correspond to the receive and transmit status codes discussed in

Transmit Status messages

on page 11 and

Receive Status messages

on page 15. See

LED blinking indicating status codes

on page 58 for a discussion of the blinking LEDs.

•

Check if the LEDs on the back of the Gateway or on or off.

The LAN ports on the back of the Gateway have LEDs. See

Gateway rear panel Ethernet

The ACP feature provides transmit satellite dish pointing information to your installer and automatic satellite dish revalidation. This ensures your satellite dish remains aligned.

Satellite systems with transmit capability — the ability to send data directly to the Internet via the satellite without a telephone connection — need to be checked periodically to be sure that the satellite dish alignment remains correct.

Satellite dishes may become misaligned because of structures settling, unauthorized tampering or, more commonly, high winds.

If the satellite dish alignment is not correct, transmissions from your equipment might interfere with other users of the satellite, and your signal might be weak.

The means used in the satellite industry to check transmit satellite dish alignment is

cross polarization co-polarization isolation measurement

or

cross pol

for short. Until recently cross pol measurements could only be made by satellite maintenance personnel.

Your ACP-equipped system can enter a test mode and initiate an automatic cross pol test session between your satellite dish and the Network Operations Center

(NOC). The test is performed by firmware in the satellite equipment, not on your PC. Since your PC is not involved, the test cannot compromise the security of your system.

If your equipment fails a periodic test, you will be contacted to schedule a service call. Other ACP features such as the Antenna Pointing - Transmitter screen (Figure 41 on page 36) are utilized by satellite service personnel to increase the accuracy of satellite dish alignment.

Assembling the DW4020

7

Your DW4020 is completely assembled by the professional installer. Should you need to move it to another location, you do not have to disassemble it at all.

You would simply disconnect the receive, transmit, and Ethernet cables. These assembly instructions have been provided in case you should ever need them.

Professional installation and service of the antenna assembly is required by the Federal Communications

Commission because the radio transmits radio frequency energy.

•

The two-way antenna assembly must be installed in a location or manner not readily accessible to children.

•

The two-way antenna assembly must be installed at least 5 feet (1.5 meters) above ground level or any nearby surface on which a person could sit or stand.

• The two-way satellite dish assembly emits radio frequency energy when in the transmit mode.

• Unplug indoor power connection before performing maintenance or adding upgrades to any satellite dish components.

• To avoid risk of injury, do not place head or other body parts between feed horn and reflector when system is operational.

DW4020 components

The DW4020 consists of all the items below. There are two satellite modems: the receive modem and transmit modem. The receive modem receives data from the satellite. It is labeled “Receive” on its front right. The receive modem must be installed on top of the transmit modem for heat dissipation. The transmit modem transmits data to the satellite. It is labeled “Transmit” on its front right.

The Gateway must be installed under the transmit modem.

Each unit is also labeled on its back, as follows:

• the receive modem is labeled

IRU

The power supply

You must use a power supply with the part number PN: 1031105-0001. The part number is on a sticker on the power supply. Verify that you are using the correct power supply. Do not use anything but the power supply supplied with the

DW4020 system (1031105-0001).

Be sure the power supply is labeled

ADP 64AB B

in the upper right hand corner of the label, above the bar codes. See Figure 55.

CAUTION

• This unit’s performance may suffer if the wrong power supply is used.

• This unit must be used with the power supply PN

1031105-0001.

• When power needs to be removed from the receive modem,

ALWAYS unplug the AC power cord from either the wall outlet, surge protector, or power strip.

• NEVER pull the power cord from the back of the receive modem. Doing so could damage the pins and also cause a short in the system.

• Power supply with the part number 1031105-0001 is to be used only in the United States and Canada.

• This unit must be used with 110-volt AC input.

• Other countries may have different standards and requirements.

Assembling the components

Follow the steps below and refer to the illustrations to assemble the DW4020 components.

CAUTION

• The components must be stacked in this order: Gateway on bottom; transmit modem on top of Gateway; receive modem on top of transmit modem. See Figure 58.

• If the components are not stacked in the proper order, the receive modem may overheat and malfunction.

• Do not block any ventilation openings. Do not install near any heat sources such as radiators, heat registers, ovens, stoves, or other apparatus (including amplifiers) that produce heat.

• Recommended ventilation space around the top and sides of the DW4020 assembly should be approximately 6 inches. Ventilation is necessary to avoid overheating.

1. Write down the receive modem serial number. It is located below the barcode on the back of the modem and is the second portion of the line. (For example, R1CF4B21E -

00827500

would be Serial Number

827500

.)

2. Be sure the power supply is not plugged into a wall outlet, surge protector, or power strip.

3. Lay two of the four clips on a table and mount the components as shown in

Figure 56. Mount the Gateway first, then the transmit modem, then the receive modem.

4. Turn the component stack right side up and install the other two clips as shown in Figure 57.

Note: The Gateway and the transmit modem have a hole at the center of each of its four feet. There is a tab on the bottom of each mounting clip, which snaps into place on the Gateway when properly aligned over the hole.There is also a tab in the middle of each mounting clip, which snaps into place on the transmit modem when properly aliged over the hole.

5. Double-check that the components are installed in this order from top to bottom: receive modem, transmit modem, Gateway (see Figure 58).
