• Remote management The modem router allows you to log in to the Web management interface from a remote location via the Internet. For security, you can limit remote management access to a specified remote IP address or range of addresses, or you can choose a nonstandard port number.

• Diagnostic functions The modem router incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote reboot. These functions allow you to test Internet connectivity and reboot the modem router. You can use these diagnostic functions directly from the DG834G v3 when you are connected on the LAN or when you are connected over the Internet via the remote management function.

Introduction

• Visual monitoring The modem router’s front panel LEDs provide an easy way to monitor its status and activity.
• Flash erasable programmable read-only memory (EPROM) for firmware upgrades.

Protocol Support

The DG834G v3 supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). “Internet Networking and TCP/IP Addressing” in Appendix C provides further information on TCP/IP.

• The Ability to Enable or Disable IP Address Sharing by NAT The DG834G v3 allows several networked PCs to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Internet service provider (ISP). This technique, known as Network Address Translation (NAT), allows the use of an inexpensive single-user ISP account. This feature can also be turned off completely while using the DG834G v3 if you want to manage the IP address scheme yourself.
• Automatic Configuration of Attached PCs by DHCP The DG834G v3 dynamically assigns network configuration information, including IP, modem router, and domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on your local network.
• DNS Proxy When DHCP is enabled and no DNS addresses are specified, the modem router provides its own address as a DNS server to the attached PCs. The modem router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.
• Classical IP (RFC 1577) Some Internet service providers, in Europe for example, use Classical IP in their ADSL services. In such cases, the modem router is able to use the Classical IP address from the ISP.
• PPP over Ethernet (PPPoE) PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an ADSL connection by simulating a dial-up connection. This feature eliminates the need to run a login program such as EnterNet or WinPOET on your computer.
• PPP over ATM (PPPoA) PPP over ATM is a protocol for connecting remote hosts to the Internet over an ADSL connection by simulating an ATM connection.

2-4 Introduction

• Dynamic DNS Dynamic DNS services allow remote users to find your network using a domain name when your IP address is not permanently assigned. The modem router contains a client that can connect to many popular Dynamic DNS services to register your dynamic IP address.
• Universal Plug and Play (UPnP) UPnP is a networking architecture that provides compatibility between networking technologies. UPnP compliant routers provide broadband users at home and small businesses with a seamless way to participate in online games, videoconferencing and other peer-to-peer services.

V irtual P rivate N etworking (VPN)

The ADSL Modem Wireless Router provides a secure encrypted connection between your local area network (LAN) and remote networks or clients. It includes the following VPN features:

• Supports 5 VPN connections.
• Supports industry standard VPN protocols The ADSL Modem Wireless Router supports standard Manual or IKE keying methods, standard MD5 and SHA-1 authentication methods, and standard DES and 3DES encryption methods. It is compatible with many other VPN products.
• Supports 3DES encryption for maximum security.
• VPN Wizard based on VPNC recommended settings.

A uto S ensing and A uto U plink™ L AN E thernet C onnections

With its internal 4-port 10/100 switch, the DG834G v3 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and capable of full-duplex or half-duplex operation.

The modem router incorporates Auto Uplink™ technology. Each local Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a 'normal' connection such as to a computer or an 'uplink' connection such as to a switch or hub. That port will then configure itself to the correct configuration. This feature also eliminates the need to worry about crossover cables, as Auto Uplink will accommodate either type of cable to make the right connection.

Introduction

Content Filtering

With its content filtering feature, the DG834G v3 prevents objectionable content from reaching your PCs. The modem router allows you to control access to Internet content by screening for keywords within Web addresses. You can configure the modem router to log and report attempts to access objectionable Internet sites.

Introduction

Chapter 3

Wireless Configuration

This chapter describes how to configure the wireless features of your 54 Mbps ADSL Modem Wireless Router Model DG834G.

Considerations for a Wireless Network

In planning your wireless network, you should consider the level of security required. You should also select the physical placement of your modem router in order to maximize the network speed.

To ensure proper compliance and compatibility between similar products in your area, the operating channel and region must be set correctly.

Observe Performance, Placement, and Range Guidelines

The operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless firewall. The latency, data throughput performance, and notebook power consumption also vary depending on your configuration choices.

Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range/performance specifications, please see Appendix A, “Technical Specifications”.

For best results, place your firewall:

• Near the center of the area in which your computers will operate
• In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls)
• Away from sources of interference, such as computers, microwaves, and cordless phones
• With the Antenna tight and in the upright position
• Away from large metal surfaces

Wireless Configuration v1.0, January 2006 3-1

The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer.

I mplement Appropriate Wireless Security

Note: Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300 feet. Such distances can allow for others outside of your immediate area to access your network.

Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The ADSL Modem Wireless Router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.

There are several ways you can enhance the security of your wireless network:

• Restrict Access Based on MAC Address. You can allow only trusted PCs to connect so that unknown PCs cannot wirelessly connect to the DG834G v3. Restricting access by MAC address adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed.
• Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies wireless network ‘discovery’ feature of some products, such as Windows XP, but the data is still exposed.

• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper.
• WPA. Wi-Fi Protected Access (WPA) data encryption provides data security. The very strong authentication along with dynamic per frame re-keying of WPA make it virtually impossible to compromise. Because this is a new standard, wireless device driver and software availability may be limited.

Understanding Wireless Settings

To configure the Wireless interface of your modem router, click the Wireless Settings link in the Setup section of the main menu. The Wireless Settings menu will appear, similar to that shown below:

Wireless Configuration v1.0, January 2006 3-3

The following parameters are in the Wireless Settings menu:

• Wireless Network.

  • Name (SSID). The Service Set ID, also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. The same Name (SSID) must be assigned to all wireless devices in your network. The default SSID is NETGEAR, but NETGEAR strongly recommends that you change your network Name to a different value.

  Note: This value is case sensitive. For example, Wireless is not the same as wireless.

  • Region. Select your country/region from the drop-down list. This field displays the region of operation for which the wireless interface is intended.

  Note: In the USA, the Region is preset according to regulatory requirements and cannot be changed. In other areas, you can and must set the Region. It may not be legal to operate the wireless access point in a region other than one of those identified in this field.

  • Channel. This field determines which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby access point.
  • Mode. The default is "g & b", which allows both "g" and "b" wireless stations to access this device. “g only” allows only 802.11g wireless stations to be used. “b only” allows 802.11b wireless stations; 802.11g wireless stations can still be used if they can operate in 802.11b mode.

• Wireless Access Point.

  • Enable Wireless Access Point. This field lets you turn off or turn on the wireless access point built in to the modem router. The wireless icon on the front of the modem router will also display the current status of the Wireless Access Point to let you know if it is disabled or enabled. The wireless access point must be enabled to allow wireless stations to access the Internet.
  • Allow Broadcast of Name (SSID). If enabled, the SSID is broadcast to all Wireless Stations. Stations which have no SSID (or a "null" value) can then adopt the correct SSID for connections to this Access Point.

Wireless Configuration

Reference Manual for the ADSL Modem Wireless Router DG834G

— Wireless Isolation. If enabled, Wireless Stations will not be able to communicate with each other or with Stations on the wired network. This feature should normally be disabled.

• Wireless Station Access List.

  — By default, any wireless computer that is configured with the correct wireless network name or SSID will be allowed access to your wireless network. For increased security, you can restrict access to the wireless network to only specific computers based on their MAC addresses. Click Setup Access List to display the Wireless Station Access List menu.

Wireless Configuration

4. Set the Region. Select the region in which the wireless interface will operate.
5. Set the Channel. The default channel is 11.

This field determines which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby wireless router or access point. Select a channel that is not being used by any other wireless networks within several hundred feet of your firewall. For more information on the wireless channel frequencies please refer to “Wireless Communications” in Appendix C.

6. For initial configuration and test, leave the Wireless Card Access List set to allow everyone access by making sure that Turn Access Control On is not selected in the Wireless Station Access List. In addition, leave the Encryption Strength set to “Disabled.”
7. Click Apply to save your changes.

Note: If you are configuring the firewall from a wireless computer and you change the firewall’s SSID, channel, or security settings, you will lose your wireless connection when you click Apply. You must then change the wireless settings of your computer to match the firewall’s new settings.

8. Configure and test your computers for wireless connectivity.

Program the wireless adapter of your computers to have the same SSID and channel that you configured in the router. Check that they have a wireless link and are able to obtain an IP address by DHCP from the firewall.

Once your computers have basic wireless connectivity to the firewall, you can configure the advanced wireless security functions of the firewall.

How to Restrict Wireless Access to Your Network

By default, any wireless PC that is configured with the correct SSID will be allowed access to your wireless network. For increased security, the 54 Mbps ADSL Modem Wireless Router Model DG834G provides several ways to restrict wireless access to your network:

• Turn off wireless connectivity completely • Restrict access based on the Wireless Network Name (SSID) • Restrict access based on the Wireless Card Access List

Wireless Configuration v1.0, January 2006 3-7

These options are discussed below.

Restricting Access to Your Network by Turning Off Wireless Connectivity

You can completely turn off the wireless portion of the DG834G v3. For example, if your notebook computer is used to wirelessly connect to your router and you take a business trip, you can turn off the wireless portion of the router while you are traveling. Other members of your household who use computers connected to the router via Ethernet cables will still be able to use the router.

Restricting Wireless Access Based on the Wireless Network Name (SSID)

The DG834G v3 can restrict wireless access to your network by not broadcasting the wireless network name (SSID). However, by default, this feature is turned off. If you turn this feature on, wireless devices will not ‘see’ your DG834G v3. You must configure your wireless devices to match the wireless network name (SSID) you configure in the ADSL Modem Wireless Router.

Note: The SSID of any wireless access adapters must match the SSID you configure in the 54 Mbps ADSL Modem Wireless Router Model DG834G. If they do not match, you will not get a wireless connection to the DG834G v3.

Restricting Wireless Access Based on the Wireless Station Access List

This list determines which wireless hardware devices will be allowed to connect to the firewall.

To restrict access based on MAC addresses, follow these steps:

1. Log in to the DG834G v3 firewall at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever LAN address and password you have set up.

Reference Manual for the ADSL Modem Wireless Router DG834G

2. From the Wireless Settings menu, Wireless Station Access List section, click the Setup Access List button to display the list, shown below:

3. Select the Turn Access Control On check box to enable restricting wireless computers by their MAC addresses.

4. If the wireless station is currently connected to the network, you can select it from the Available Wireless Stations list. Click Add to add the station to the Trusted Wireless Stations list.

5. If the wireless station is not currently connected, you can enter its address manually. Enter the MAC address of the authorized computer. The MAC address is usually printed on the wireless card, or it may appear in the modem router’s DHCP table. The MAC address will be 12 hexadecimal digits.

Click Add to add your entry. You can add several stations to the list, but the entries will be discarded if you do not click Apply.

Wireless Configuration

You can copy and paste the MAC addresses from the modem router’s Attached Devices menu into the MAC Address box of this menu. To do this, configure each wireless computer to obtain a wireless link to the modem router. The computer should then appear in the Attached Devices menu.

Note: If you are configuring the modem router from a wireless computer whose MAC address is not in the Trusted Wireless Stations list, and you select Trusted Wireless Stations only, you will lose your wireless connection when you click Apply. You must then access the modem router from a wired computer to make any further changes.

6. Make sure the Turn Access Control On check box is selected, then click Apply.

Now, only devices on this list will be allowed to wirelessly connect to the DG834G v3. This prevents unauthorized access to your network.

Choosing WEP Authentication and Security Encryption Methods

Wireless Configuration

Restricting wireless access prevents intruders from connecting to your network. However, the wireless data transmissions are still vulnerable to snooping. Using the WEP data encryption settings described below will prevent a determined intruder from eavesdropping on your wireless data communications. Also, if you are using the Internet for such activities as purchases or banking, those Internet sites use another level of highly secure encryption called SSL. You can tell if a web site is using SSL because the web address begins with HTTPS rather than HTTP.

Authentication Type Selection

The DG834G v3 lets you select the following wireless authentication schemes.

• Automatic

• Open System

• Shared key

Note: The authentication scheme is separate from the data encryption. You can choose an authentication scheme which requires a shared key but still leave the data transmissions unencrypted. If you require strong security, use both the Shared Key and WEP encryption settings.

Set your wireless adapter according to the authentication scheme you choose for the ADSL Modem Wireless Router. Please refer to “Wireless Communications” in Appendix C for a full explanation of each of these options, as defined by the IEEE 802.11g wireless communication standard.

Encryption Choices

Please refer to “Wireless Communications” in Appendix C for a full explanation of each of the following choices, as defined by the IEEE 802.11g wireless communication standard. Choose the encryption strength from the drop-down list:

Disable. No encryption will be applied. This setting is useful for troubleshooting your wireless connection, but leaves your wireless data fully exposed.

64 or 128 bit WEP. When 64 Bit WEP or 128 Bit WEP is selected, WEP encryption will be applied.

If WEP is enabled, you can manually or automatically program the four data encryption keys. These values must be identical on all computers and access points in your network.

Wireless Configuration

There are two methods for creating WEP encryption keys:

• Passphrase. Enter a word or group of printable characters in the Passphrase box and click the Generate button.
• Manual. 64-bit WEP: Enter 10 hexadecimal digits (any combination of 0-9, a-f, or A-F). 128-bit WEP: Enter 26 hexadecimal digits (any combination of 0-9, a-f, or A-F).

Select the radio button for the key you want to make active.

How to Configure WEP

To configure WEP data encryption, follow these steps:

1. Log in to the DG834G v3 firewall at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever LAN address and password you have set up.
2. Click the Wireless Settings link in the Setup section of the main menu for the DG834G v3 modem router.
