Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterIntroduction 2-5August 2005• DNS Proxy When DHCP is enabled and no DNS addresses are specified, the wireless ADSL modem router provides its own address as a DNS server to the attached PCs. The wireless ADSL 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 wireless ADSL 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. • 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 wireless ADSL 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. Content FilteringWith its content filtering feature, the DG834PN prevents objectionable content from reaching your PCs. The wireless ADSL modem router allows you to control access to Internet content by screening for keywords within Web addresses. You can configure the wireless ADSL modem router to log and report attempts to access objectionable Internet sites.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router2-6 IntroductionAugust 2005Auto Sensing and Auto Uplink™ LAN Ethernet ConnectionsWith its internal 4-port 10/100 switch, the DG834PN 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 wireless ADSL modem router incorporates Auto UplinkTM 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.What’s in the Box?The product package should contain the following items:• DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router• AC power adapter (varies by region)• Category 5 (Cat 5) Ethernet cable• Telephone cable• Microfilters (quantity and type vary by region)•Resource CD, including:—This guide— Application Notes• A printed Quick Installation Guide• Warranty and Support Information cardsIf any of the parts are incorrect, missing, or damaged, contact your NETGEAR dealer.

Wireless Configuration 4-1August 2005Chapter 4 Wireless ConfigurationThis chapter describes how to configure the wireless features of your DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router.Considerations for a Wireless NetworkIn planning your wireless network, you should consider the level of security required. You should also select the physical placement of your wireless ADSL modem router in order to maximize the network speed. For further information, refer to Appendix D, “Wireless Networking Basics”.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 GuidelinesThe 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.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 surfacesNote: 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”.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router4-2 Wireless ConfigurationAugust 2005The 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.Implement Appropriate Wireless Security 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 DG834PN RangeMax Wireless ADSL Modem Router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.Figure 4-1: DG834PN wireless data security optionsThere 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 DG834PN. 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. 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.1) Open System: Easy but no security2) MAC Access List: No data security3) WEP: Security but some performance impact4) WPA-PSKWireless DataSecurity OptionsRange: Up to 300 FeetPCsServersDG834PNNEED NEW IMAGE

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 Restricting Wireless Access to Your NetworkBy default, any wireless PC that is configured with the correct SSID will be allowed access to your wireless network. For increased security, the DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router 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 ListThese options are discussed below.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.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterWireless Configuration 4-9August 2005Figure 4-4: Wireless Access Point settingsRestricting Access to Your Network by Turning Off Wireless ConnectivityYou can completely turn off the wireless portion of the DG834PN. 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 DG834PN 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 DG834PN. You must configure your wireless devices to match the wireless network name (SSID) you configure in the DG834PN RangeMax Wireless ADSL Modem Router.Note: The SSID of any wireless access adapters must match the SSID you configure in the DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router. If they do not match, you will not get a wireless connection to the DG834PN.Restricting Wireless Access Based on the Wireless Station Access ListThis 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 DG834PN 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.

This prevents unauthorized access to your network. Choosing WEP Authentication and Security Encryption MethodsFigure 4-6. Security Encryption sectionRestricting 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 DG834PN lets you select the following wireless authentication schemes. Note: If you are configuring the wireless ADSL 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 wireless ADSL modem router from a wired computer to make any further changes.

Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterProtecting Your Network 5-3August 2005Blocking Keywords, Sites, and ServicesThe wireless ADSL modem router provides a variety of options for blocking Internet based content and communications services. With its content filtering feature, the DG834PN RangeMax Wireless ADSL Modem Router prevents objectionable content from reaching your PCs. The wireless ADSL modem router allows you to control access to Internet content by screening for keywords within Web addresses. Key content filtering options include:• Keyword blocking of HTTP traffic.• Outbound Service Blocking limits access from your LAN to Internet locations or services that you specify as off-limits.• Denial of Service (DoS) protection. Automatically detects and thwarts Denial of Service (DoS) attacks such as Ping of Death, SYN Flood, LAND Attack and IP Spoofing.• Blocking unwanted traffic from the Internet to your LAN.The section below explains how to configure your wireless ADSL modem router to perform these functions.How to Block Keywords and SitesThe DG834PN RangeMax Wireless ADSL Modem Router allows you to restrict access to Internet content based on functions such as Web addresses and Web address keywords. 1.

Click Apply to save your settings.Firewall RulesFirewall rules are used to block or allow specific traffic passing through from one side of the router to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine what outside resources local users can have access to.A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of the DG834PN are:• Inbound: Block all access from outside except responses to requests from the LAN side.• Outbound: Allow all access from the LAN side to the outside.You can define additional rules that will specify exceptions to the default rules. By adding custom rules, you can block or allow access based on the service or application, source or destination IP addresses, and time of day. You can also choose to log traffic that matches or does not match the rule you have defined.You can change the order of precedence of rules so that the rule that applies most often will take effect first. See “Order of Precedence for Rules” on page 5-11 for more details.To access the rules configuration of the DG834PN, click the Firewall Rules link on the main menu, then click Add for either an Outbound or Inbound Service.Figure 5-4: Rules menu

At the script prompt, enter the number of the desired new position and click OK.Inbound Rules (Port Forwarding)Because the DG834PN uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet. The rule tells the wireless ADSL modem router to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding.Remember that allowing inbound services opens holes in your firewall. Only enable those ports that are necessary for your network. Following are two application examples of inbound rules:Inbound Rule Example: A Local Public Web ServerIf you host a public Web server on your local network, you can define a rule to allow inbound Web (HTTP) requests from any outside IP address to the IP address of your Web server at any time of day. This rule is shown in Figure 5-5:Note: Some 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 the Acceptable Use Policy of your ISP.

Select the desired option: • Any — all IP addresses are covered by this rule. • Address range — if this option is selected, you must enter the Start and Finish fields. • Single address — enter the required address in the Start field. •Log You can select whether the traffic will be logged. The choices are:• Never — no log entries will be made for this service.• Always — any traffic for this service type will be logged.• Match — traffic of this type which matches the parameters and action will be logged.• Not match — traffic of this type which does not match the parameters and action will be logged.Inbound Rule Example: Allowing VideoconferencingIf you want to allow incoming videoconferencing to be initiated from a restricted range of outside IP addresses, such as from a branch office, you can create an inbound rule. In the example shown in Figure 5-6, CU-SeeMe connections are allowed only from a specified range of external IP addresses. In this case, we have also specified logging of any incoming CU-SeeMe requests that do not match the allowed parameters.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterProtecting Your Network 5-9August 2005Figure 5-6: Rule example: Videoconference from Restricted AddressesConsiderations for Inbound Rules• If your external IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires. Consider using the Dynamic DNS feature in the Advanced menu so that external users can always find your network.• If the IP address of the local server computer is assigned by DHCP, it may change when the computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu to keep the computer’s IP address constant.• Local computers must access the local server using the computer’s local LAN address (192.168.0.11 in the example in Figure 5-6 above). Attempts by local computers to access the server using the external WAN IP address will fail.Outbound Rules (Service Blocking)The DG834PN allows you to block the use of certain Internet services by computers on your network. This is called service blocking or port filtering. You can define an outbound rule to block Internet access from a local computer based on:• IP address of the local computer (source address)• IP address of the Internet site being contacted (destination address)•Time of day• Type of service being requested (service port number)
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router5-10 Protecting Your NetworkAugust 2005Following is an application example of outbound rules:Outbound Rule Example: Blocking Instant MessengerIf you want to block Instant Messenger usage by employees during working hours, you can create an outbound rule to block that application from any internal IP address to any external address according to the schedule that you have created in the Schedule menu. You can also have the wireless ADSL modem router log any attempt to use Instant Messenger during that blocked period.Figure 5-7: Rule example: Blocking Instant MessengerThe parameters are:•Service From this list, select the application or service to be allowed or blocked.

Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router5-12 Protecting Your NetworkAugust 2005Figure 5-8: Rules table with examplesFor any traffic attempting to pass through the firewall, the packet information is subjected to the rules in the order shown in the Rules Table, beginning at the top and proceeding to the default rules at the bottom. In some cases, the order of precedence of two or more rules may be important in determining the disposition of a packet. The Move button allows you to relocate a defined rule to a new position in the table.ServicesServices are functions performed by server computers at the request of client computers. For example, Web servers serve Web pages, time servers serve time and date information, and game hosts serve data about other players’ moves. When a computer on the Internet sends a request for service to a server computer, the requested service is identified by a service or port number. This number appears as the destination port number in the transmitted IP packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web server) request.The service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application.Although the DG834PN already holds a list of many service port numbers, you are not limited to these choices. Use the procedure below to create your own service definitions.

Advanced Configuration 7-1August 2005Chapter 7 Advanced Configuration This chapter describes how to configure the advanced features of your DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router. Configuring Advanced SecurityThe DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router provides a variety of advanced features, such as:• Setting up a Demilitarized Zone (DMZ) Server• Connecting Automatically, as Required• Disabling Port Scan and DOS Protection• Responding to a Ping on the Internet WAN Port•MTU Size • Flexibility on configuring your LAN TCP/IP settings• Using the Router as a DHCP Server• Configuring Dynamic DNS• Configuring Static RoutesThese features are discussed below.Setting Up A Default DMZ ServerThe Default DMZ Server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The wireless ADSL modem router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local computer can run the application properly if that computer’s IP address is entered as the Default DMZ Server.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router7-2 Advanced ConfigurationAugust 2005Incoming traffic from the Internet is normally discarded by the wireless ADSL modem router unless the traffic is a response to one of your local computers or a service that you have configured in the Ports menu. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the Default DMZ Server.How to Configure a Default DMZ ServerTo assign a computer or server to be a Default DMZ server, follow these steps: 1. Log in to the wireless ADSL modem router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever Password and LAN address you have chosen for the wireless ADSL modem router.2. From the Main Menu, under Advanced, click the WAN Setup link to view the page shown in Figure 7-1:Figure 7-1: WAN Setup Page3. Select the Default DMZ Server check box.4. Type the IP address for that server. 5. Click Apply to save your changes. Note: For security reasons, you should avoid using the Default DMZ Server feature. When a computer is designated as the Default DMZ Server, it loses much of the protection of the firewall, and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterAdvanced Configuration 7-3August 2005Connect Automatically, as Required Normally, this option should be enabled, so that an Internet connection will be made automatically, whenever Internet-bound traffic is detected. If this causes high connection costs, you can disable this setting. If disabled, you must connect manually, using the sub-screen accessed from the "Connection Status" button on the Status screen.If you have an "Always on" connection, this setting has no effect.Disable Port Scan and DOS ProtectionThe Firewall protects your LAN against Port Scans and Denial of Service (DOS) attacks. This should be disabled only in special circumstances.Respond to Ping on Internet WAN Port If you want the wireless ADSL modem router to respond to a 'ping' from the Internet, select the ‘Respond to Ping on Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your wireless ADSL modem router to be discovered. Do not select this box unless you have a specific reason to do so.MTU Size The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, or 1492 Bytes for PPPoE connections. For some ISPs you may need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.Configuring LAN IP SettingsThe LAN IP Setup menu allows configuration of LAN IP services such as DHCP and RIP. These features can be found under the Advanced heading in the Main Menu of the browser interface.The wireless ADSL modem router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a DHCP server. The wireless ADSL modem router’s default LAN IP configuration is:
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router7-4 Advanced ConfigurationAugust 2005• LAN IP addresses—192.168.0.1• Subnet mask—255.255.255.0These addresses are part of the Internet Engineering Task Force (IETF)-designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in this menu.Figure 7-2: LAN IP Setup MenuThe LAN TCP/IP Setup parameters are:• IP Address This is the LAN IP address of the wireless ADSL modem router.• IP Subnet Mask This is the LAN Subnet Mask of the wireless ADSL modem router. Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or wireless ADSL modem router.• RIP Direction RIP (Router Information Protocol) allows a wireless ADSL modem router to exchange routing information with other routers. The RIP Direction selection controls how the Wireless ADSL Modem Router sends and receives RIP packets. Both is the default. — When set to Both or Out Only, the wireless ADSL modem router will broadcast its routing table periodically. — When set to Both or In Only, it will incorporate the RIP information that it receives.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterAdvanced Configuration 7-5August 2005— When set to None, it will not send any RIP packets and will ignore any RIP packets received. • RIP Version This controls the format and the broadcasting method of the RIP packets that the wireless ADSL modem router sends. It recognizes both formats when receiving. By default, this is set for RIP-1. — RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you have an unusual network setup. — RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 format. — RIP-2B uses subnet broadcasting. — RIP-2M uses multicasting.DHCPBy default, the wireless ADSL modem router will function as a DHCP (Dynamic Host Configuration Protocol) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the wireless ADSL modem router's LAN. The assigned default gateway address is the LAN address of the router. IP addresses will be assigned to the attached PCs from a pool of addresses specified in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See “IP Configuration by DHCP”on page B-9 for an explanation of DHCP and information about how to assign IP addresses for your network. Use Router as DHCP serverIf another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the ‘Use router as DHCP server’ check box. Otherwise, leave it selected. Note: If you change the LAN IP address of the wireless ADSL modem router while connected through the browser, you will be disconnected. You must then open a new connection to the new IP address and log in again.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router7-6 Advanced ConfigurationAugust 2005Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP Address. These addresses should be part of the same IP address subnet as the router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.0.2 and 192.168.0.254, although you may want to save part of the range for devices with fixed addresses.The router will deliver the following parameters to any LAN device that requests DHCP:• An IP Address from the range you have defined• Subnet Mask• Gateway IP Address is the router’s LAN IP address• Primary DNS Server, if you entered a Primary DNS address in the Basic Settings menu; otherwise, the router’s LAN IP address• Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings menu• WINS Server, short for Windows Internet Naming Service Server, determines the IP address associated with a particular Windows computer. A WINS server records and reports a list of names and IP address of Windows PCs on its local network. If you connect to a remote network that contains a WINS server, enter the server’s IP address here. This allows your PCs to browse the network using the Network Neighborhood feature of Windows.Reserved IP addressesWhen you specify a reserved IP address for a computer on the LAN, that computer will always receive the same IP address each time it access the router’s DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings. To reserve an IP address: 1. Click the Add button. 2. In the IP Address box, type the IP address to assign to the computer or server. Choose an IP address from the router’s LAN subnet, such as 192.168.0.x. 3. Type the MAC Address of the computer or server. Tip: If the computer is already present on your network, you can copy its MAC address from the Attached Devices menu and paste it here. 4. Click Apply to enter the reserved address into the table. Note: The reserved address will not be assigned until the next time the computer contacts the router's DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew.

Click Apply to save your changes.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router7-8 Advanced ConfigurationAugust 2005Configuring Dynamic DNSIf your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial dynamic DNS service that will allow you to register your domain to their IP address, and will forward traffic directed at your domain to your frequently-changing IP address. The router contains a client that can connect to a dynamic DNS service provider. To use this feature, you must select a service provider and obtain an account with them. After you have configured your account information in the router, whenever your ISP-assigned IP address changes, your router will automatically contact your dynamic DNS service provider, log in to your account, and register your new IP address.How to Configure Dynamic DNS1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.2. From the Main Menu of the browser interface, under Advanced, select Dynamic DNS to display the page below.Figure 7-4: Dynamic DNS menu
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterAdvanced Configuration 7-9August 20053. Access the Web site of one of the dynamic DNS service providers whose names appear in the ‘Service Provider’ box, and register for an account. For example, for dyndns.org, go to www.dyndns.org.4. Select the “Use a dynamic DNS service” check box. 5. Select the name of your dynamic DNS Service Provider. 6. Type the Host Name that your dynamic DNS service provider gave you. The dynamic DNS service provider may call this the domain name. If your URL is myName.dyndns.org, then your Host Name is “myName.”7. Type the User Name for your dynamic DNS account. 8. Type the Password (or key) for your dynamic DNS account. 9. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use wildcards check box to activate this feature. For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org10. Click Apply to save your configuration. Using Static RoutesStatic Routes provide additional routing information to your router. Under normal circumstances, the router has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network.Static Route ExampleAs an example of when a static route is needed, consider the following case:• Your primary Internet access is through a cable modem to an ISP.• You have an ISDN router on your home network for connecting to the company where you are employed. This router’s address on your LAN is 192.168.0.100.Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the dynamic DNS service will not work because private addresses will not be routed on the Internet.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router7-10 Advanced ConfigurationAugust 2005• Your company’s network is 134.177.0.0.When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the wireless ADSL modem router, and a second static route was created to your local network for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your request to the company where you are employed, and the request will likely be denied by the company’s firewall.In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.0.100. The static route would look like Figure 7-6.In this example:• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.x.x addresses. • The Wireless ADSL Modem Router IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100. • A Metric value of 1 will work since the ISDN router is on the LAN. This represents the number of routers between your network and the destination. This is a direct connection so it is set to 1.• Private is selected only as a precautionary security measure in case RIP is activated.How to Configure Static Routes1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.2. From the Main Menu of the browser interface, under Advanced, click Static Routes to view the Static Routes menu, shown in Figure 7-5.

Troubleshooting 8-1August 2005Chapter 8 TroubleshootingThis chapter gives information about troubleshooting your DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router. After each problem description, instructions are provided to help you diagnose and solve the problem. For the common problems listed, go to the section indicated.• Is the router on?• Have I connected the router correctly?Go to “Basic Functioning” on page 8-1.• I can’t access the router’s configuration with my browser.Go to “Troubleshooting the Web Configuration Interface” on page 8-3.• I’ve configured the router but I can’t access the Internet.Go to “Troubleshooting the ISP Connection” on page 8-4.• I can’t remember the router’s configuration password.• I want to clear the configuration and start over again.Go to “Restoring the Default Configuration and Password” on page 8-9.Basic FunctioningAfter you turn on power to the router, the following sequence of events should occur:1. When power is first applied, verify that the Power LED is on (see “The Router’s Front Panel” on page 2-6 for an illustration and explanation of the LEDs).2. Verify that the Test LED lights within a few seconds, indicating that the self-test procedure is running.3. After approximately 10 seconds, verify that:a. The Test LED is not lit.b. The LAN port LEDs are lit for any local ports that are connected.c. The WAN port LED is lit.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router8-2 TroubleshootingAugust 2005If a port’s LED is lit, a link has been established to the connected device. If a LAN port is connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the LED will be amber.If any of these conditions does not occur, refer to the appropriate following section.Power LED Not OnIf the Power and other LEDs are off when your router is turned on:• Make sure that the power cord is properly connected to your router and that the power supply adapter is properly connected to a functioning power outlet. • Check that you are using the 12 V DC power adapter supplied by NETGEAR for this product.If the error persists, you have a hardware problem and should contact technical support.Test LED Never Turns On or Test LED Stays OnWhen the router is turned on, the Test LED turns on for about 10 seconds and then turns off. If the Test LED does not turn on, or if it stays on, there is a fault within the router.If you experience problems with the Test LED:• Cycle the power to see if the router recovers and the LED blinks for the correct amount of time.If all LEDs including the Test LED are still on one minute after power up:• Cycle the power to see if the router recovers.• Clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.0.1. This procedure is explained in “Using the Reset button” on page 8-9.If the error persists, you might have a hardware problem and should contact technical support.LAN or WAN Port LEDs Not OnIf either the LAN LEDs or WAN LED do not light when the Ethernet connection is made, check the following:• Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterTroubleshooting 8-3August 2005• Make sure that power is turned on to the connected hub or workstation.• Be sure you are using the correct cable:— When connecting the router’s WAN ADSL port, use the cable that was supplied with the DG834PN. Troubleshooting the Web Configuration InterfaceIf you are unable to access the router’s Web Configuration interface from a computer on your local network, check the following:• If you are using an Ethernet-connected computer, check the Ethernet connection between the computer and the router as described in the previous section.• Make sure your computer’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your computer’s address should be in the range of 192.168.0.2 to 192.168.0.254. Refer to “Verifying TCP/IP Properties” on page C-6 or “Verifying TCP/IP Properties for Macintosh Computers” on page C-17 to find your computer’s IP address. Follow the instructions in Appendix C to configure your computer.Note: If your computer’s IP address is shown as 169.254.x.x: Recent versions of Windows and MacOS will generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router and reboot your computer.• If your router’s IP address was changed and you do not know the current IP address, clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.0.1. This procedure is explained in “Using the Reset button” on page 8-9.• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded.• Try quitting the browser and launching it again.• Make sure you are using the correct login information. The factory default login name is admin and the password is password. Make sure that CAPS LOCK is off when entering this information.If the router does not save changes you have made in the Web Configuration Interface, check the following:• When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, or your changes are lost.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router8-4 TroubleshootingAugust 2005• Click the Refresh or Reload button in the Web browser. The changes may have occurred, but the Web browser may be caching the old configuration.Troubleshooting the ISP ConnectionIf your router is unable to access the Internet, you should check the ADSL connection, then the WAN TCP/IP connection. ADSL linkIf your router is unable to access the Internet, you should first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the WAN LED.WAN LED Green or Blinking GreenIf your WAN LED is green or blinking green, then you have a good ADSL connection. You can be confident that the service provider has connected your line correctly and that your wiring is correct.WAN LED Blinking YellowIf your WAN LED is blinking yellow, then your wireless ADSL modem router is attempting to make an ADSL connection with the service provider. The LED should turn green within several minutes. If the WAN LED does not turn green, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being careful to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones.If disconnecting telephones does not result in a green WAN LED, there may be a problem with your wiring. If the telephone company has tested the ADSL signal at your Network Interface Device (NID), then you may have poor quality wiring in your house.WAN LED OffIf the WAN LED is off, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being careful to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterTroubleshooting 8-5August 2005If disconnecting telephones does not result in a green WAN LED the problem may be one of the following:• Check that the telephone company has made the connection to your line and tested it.• Verify that you are connected to the correct telephone line. If you have more than one phone line, be sure that you are connected to the line with the ADSL service. It may be necessary to use a swapper if you ADSL signal is on pins 1 and 4 or the RJ-11 jack. The DG834PN RangeMax Wireless ADSL Modem Router uses pins 2 and 3.Obtaining a WAN IP AddressIf your wireless ADSL modem router is unable to access the internet, and your WAN LED is green or blinking green, you should determine whether the wireless ADSL modem router is able to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your wireless ADSL modem router must request an IP address from the ISP. You can determine whether the request was successful using the browser interface.To check the WAN IP address from the browser interface: 1. Launch your browser and select an external site such as www.netgear.com.2. Access the Main Menu of the wireless ADSL modem router’s configuration at http://192.168.0.1. 3. Under the Maintenance heading check that an IP address is shown for the WAN Port. If 0.0.0.0 is shown, your wireless ADSL modem router has not obtained an IP address from your ISP.If your router is unable to obtain an IP address from the ISP, the problem may be one of the following:• Your ISP may require a Multiplexing Method or Virtual Path Identifier/Virtual Channel Identifier parameter. Verify with your ISP the Multiplexing Method and parameter value, and update the router’s ADSL Settings accordingly.• Your ISP may require a login program. Ask your ISP whether they require PPP over Ethernet (PPPoE) or PPP over ATM (PPPOA) login.• If you have selected a login program, you may have incorrectly set the Service Name, User Name and Password. See “Troubleshooting PPPoE or PPPoA”, below.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router8-6 TroubleshootingAugust 2005• Your ISP may check for your computer's host name. Assign the computer Host Name of your ISP account to the wireless ADSL modem router in the browser-based Setup Wizard.• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for your computer’s MAC address. In this case:Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.ORConfigure your router to spoof your computer’s MAC address. This can be done in the Basic Settings menu. Refer to “Manually Configuring Your Internet Connection” on page 3-10.Troubleshooting PPPoE or PPPoAThe PPPoA or PPPoA connection can be debugged as follows:1. Access the Main Menu of the router at http://192.168.0.1.2. Under the Maintenance heading, select the Router Status link.3. Click the Connection Status button.4. If all of the steps indicate “OK” then your PPPoE or PPPoA connection is up and working.5. If any of the steps indicates “Failed”, you can attempt to reconnect by clicking “Connect”. The wireless ADSL modem router will continue to attempt to connect indefinitely.If you cannot connect after several minutes, you may be using an incorrect Service Name, User Name or Password. There also may be a provisioning problem with your ISP.Troubleshooting Internet BrowsingIf your wireless ADSL modem router can obtain an IP address but your computer is unable to load any Web pages from the Internet:• Your computer may not recognize any DNS server addresses. Note: Unless you connect manually, the wireless ADSL modem router will not authenticate using PPPoE or PPPoA until data is transmitted to the network.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterTroubleshooting 8-7August 2005A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the wireless ADSL modem router’s configuration, reboot your computer and verify the DNS address as described in “Verifying TCP/IP Properties” on page C-6. Alternatively, you can configure your computer manually with DNS addresses, as explained in your operating system documentation.• Your computer may not have the wireless ADSL modem router configured as its TCP/IP wireless ADSL modem router.If your computer obtains its information from the wireless ADSL modem router by DHCP, reboot the computer and verify the wireless ADSL modem router address as described in “Verifying TCP/IP Properties” on page C-6.Troubleshooting a TCP/IP Network Using the Ping UtilityMost TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer.Testing the LAN Path to Your RouterYou can ping the router from your computer to verify that the LAN path to your router is set up correctly.To ping the router from a PC running Windows 95 or later:1. From the Windows toolbar, click the Start button and select Run.2. In the field provided, type Ping followed by the IP address of the router, as in this example:ping 192.168.0.13. Click OK.You should see a message like this one:Pinging <IP address> with 32 bytes of dataIf the path is working, you see this message:Reply from < IP address >: bytes=32 time=NN ms TTL=xxxIf the path is not working, you see this message:Request timed out
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem Router8-8 TroubleshootingAugust 2005If the path is not functioning correctly, you could have one of the following problems:• Wrong physical connections— Make sure the LAN port LED is on. If the LED is off, follow the instructions in “LAN or WAN Port LEDs Not On” on page 8-2.— Check that the corresponding Link LEDs are on for your network interface card and for the hub ports (if any) that are connected to your workstation and router.• Wrong network configuration— Verify that the Ethernet card driver software and TCP/IP software are both installed and configured on your PC or workstation.— Verify that the IP address for your router and your workstation are correct and that the addresses are on the same subnet.Testing the Path from Your Computer to a Remote DeviceAfter verifying that the LAN path works correctly, test the path from your PC to a remote device. From the Windows run menu, type:PING -n 10 <IP address>where <IP address> is the IP address of a remote device such as your ISP’s DNS server.If the path is functioning correctly, replies as in the previous section are displayed. If you do not receive replies:— Check that your PC has the IP address of your router listed as the default wireless ADSL modem router. If the IP configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the router is listed as the default wireless ADSL modem router as described in “Verifying TCP/IP Properties” on page C-6.— Check to see that the network address of your PC (the portion of the IP address specified by the netmask) is different from the network address of the remote device.— Check that your cable or DSL modem is connected and functioning.— If your ISP assigned a host name to your PC, enter that host name as the Account Name in the Basic Settings menu.
Reference Manual for the Model DG834PN 108 Mbps RangeMaxTM Wireless ADSL Modem RouterTroubleshooting 8-9August 2005— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized PC. Refer to “Manually Configuring Your Internet Connection” on page 3-10.Restoring the Default Configuration and PasswordThis section explains how to restore the factory default configuration settings, changing the router’s administration password to password and the IP address to 192.168.0.1. You can erase the current configuration and restore factory defaults in two ways:• Use the Erase function of the Web Configuration Manager (see “Backing Up, Restoring, or Erasing Your Settings” on page 6-1).• Use the Default Reset button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known.Using the Reset buttonTo restore the factory default configuration settings without knowing the administration password or IP address, you must use the Default Reset button on the rear panel of the router.1. Press and hold the Default Reset button until the Test LED turns on (about 10 seconds).2. Release the Default Reset button and wait for the router to reboot.Problems with Date and TimeThe E-mail menu in the Content Filtering section displays the current date and time of day. The DG834PN RangeMax Wireless ADSL Modem Router uses the Network Time Protocol (NTP) to obtain the current time from one of several Network Time Servers on the Internet. Each entry in the log is stamped with the date and time of day. Problems with the date and time function can include:• Date shown is January 1, 2000 Cause: The router has not yet successfully reached a Network Time Server. Check that your Internet access settings are configured correctly. If you have just completed configuring the router, wait at least five minutes and check the date and time again.
