Hardware Setup8Centria WNDR4700/WNDR4720 Unpack Your RouterOpen the box and remove the router, cables, and installation guide.Ethernet cable Power adapterCentriaTray HDD(WNDR4720)Figure 1. Check the package contentsYour box contains the following items:•Centria WNDR4700/WNDR4720•AC power adapter and power cord (plug varies by region)•Category 5 (Cat 5) Ethernet cable•Installation guide with cabling and router setup instructionsIf any parts are incorrect, missing, or damaged, contact your NETGEAR dealer. Keep the carton and original packing materials, in case you need to return the product for repair. Position Your RouterThe router lets you access your network from virtually anywhere within the operating range of your wireless network. However, the operating distance or range of your wireless connection can vary significantly depending on the physical placement of your router. For example, the thickness and number of walls the wireless signal passes through can limit the range. For best results, place your router: •Near the center of the area where your computers and other devices operate, and preferably within line of sight to your wireless devices.•So it is accessible to an AC power outlet and near Ethernet cables for wired computers.•In an elevated location such as a high shelf, keeping the number of walls and ceilings between the router and your other devices to a minimum.
Hardware Setup9 Centria WNDR4700/WNDR4720•Away from electrical devices that are potential sources of interference. Equipment that might cause interference includes ceiling fans, home security systems, microwaves, computers, the base of a cordless phone, or 2.4 GHz cordless phone. •Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and concrete can also affect your wireless signal.When you use multiple access points, it is better if adjacent access points use different radio frequency channels to reduce interference. The recommended channel spacing between adjacent access points is five channels (for example, use Channels 1 and 6, or 6 and 11).Hardware FeaturesBefore you cable your router, take a moment to become familiar with the front, side, and back panels and the label. Pay particular attention to the LEDs on the front panel.Front and Side PanelThe router front panel has the status LEDs and icons shown in the following figure.LEDsWPSWiFi On/OffBackupUSB portCard readerFigure 2.

Getting Started with NETGEAR genieConnecting to the routerThis chapter explains how to use NETGEAR genie to set up your router after you complete cabling as described in the installation guide and in the previous chapter.This chapter contains the following sections:•Router Setup Preparation •Types of Logins and Access •NETGEAR genie Setup •Use NETGEAR genie after Installation •Upgrade Firmware •Router Dashboard (Basic Home Screen) •Join the Wireless Network •NETGEAR genie App and Mobile genie App
Getting Started with NETGEAR genie15 Centria WNDR4700/WNDR4720Router Setup PreparationYou can set up your router with the NETGEAR genie automatically, or you can use the genie menus and screens to set up your router manually. Before you start the setup process, get your ISP information, and make sure the computers and devices in the network have the settings described here.Use Standard TCP/IP Properties for DHCPIf you set up your computer to use a static IP address, you need to change the settings so that it uses Dynamic Host Configuration Protocol (DHCP). Gather ISP InformationIf you have DSL broadband service, you might need the following information to set up your router and to check that your Internet configuration is correct. Your Internet service provider (ISP) should have provided you with all of the information needed to connect to the Internet. If you cannot locate this information, ask your ISP to provide it. When your Internet connection is working, you no longer need to launch the ISP’s login program on your computer to access the Internet. When you start an Internet application, your router automatically logs you in.•The ISP configuration information for your DSL account•ISP login name and password•Fixed or static IP address settings (special deployment by ISP; this is rare)Wireless Devices and Security SettingsMake sure that the wireless device or computer that you are using supports WPA or WPA2 wireless security, which is the wireless security supported by the router. Types of Logins and AccessThere are separate types of logins that have different purposes. It is important that you understand the difference so that you know which login to use when.•Router login logs you in to the router interface from NETGEAR genie. See UseNETGEAR genie after Installation on page 17 for details about this login.•ISP login logs you in to your Internet service. Your service provider has provided you with this login information in a letter or some other way. If you cannot find this login information, contact your service provider.•Wireless network key or password. Your router is preset with a unique wireless network name (SSID) and password for wireless access. This information is on the label on the bottom of your router.

Click Apply to save your selections.Guest Network Wireless Security OptionsA security option is the type of security protocol applied to your wireless network. The security protocol in force encrypts data transmissions and ensures that only trusted devices receive authorization to connect to your network. Wi-Fi Protected Access (WPA) has several options including pre-shared key (PSK) encryption. This section presents an overview of the security options and provides guidance on when to use which option. Note that it is also possible to set up a guest network without wireless security. NETGEAR does not recommend this.WPA EncryptionWPA encryption is built into all hardware that has the Wi-Fi-certified seal. This seal means the product is authorized by the Wi-Fi Alliance (http://www.wi-fi.org/) because it complies with the worldwide single standard for high-speed wireless local area networking. WPA uses a passphrase to perform authentication and generate the initial data encryption keys. Then it dynamically varies the encryption key. WPA-PSK uses Temporal Key Integrity Protocol (TKIP) data encryption, implements most of the IEEE 802.11i standard, and is designed to work with all wireless network interface cards, but not all wireless access points. It is superseded by WPA2-PSK.WPA2-PSK is stronger than WPA-PSK. It is advertised to be theoretically indecipherable due to the greater degree of randomness in encryption keys that it generates. WPA2-PSK gets higher speed because it is usually implemented through hardware, while WPA-PSK is usually implemented through software. WPA2-PSK uses a passphrase to authenticate and generate the initial data encryption keys. Then it dynamically varies the encryption key. WPS-PSK + WPA2-PSK Mixed Mode can provide broader support for all wireless clients. WPA2-PSK clients get higher speed and security, and WPA-PSK clients get decent speed and security. The product documentation for your wireless adapter and WPA client software should have instructions about configuring their WPA settings.

IGMP proxying allows a computer on the local area network (LAN) to receive the multicast traffic it is interested in from the Internet. If you do not need this feature, you can select this check box to disable it.•MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs, you might need to reduce the MTU. This is rarely required, and should not be done unless you are sure it is necessary for your ISP connection. See Change the MTU Size on page 38.•NAT Filtering. Network Address Translation (NAT) determines how the router processes inbound traffic. Secured NAT provides a secured firewall to protect the computers on the LAN from attacks from the Internet, but might prevent some Internet games, point-to-point applications, or multimedia applications from functioning. Open NAT provides a much less secured firewall, but allows almost all Internet applications to function. Default DMZ ServerThe default DMZ server feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The router is programmed to recognize some of these applications and to work correctly with them, but there are other applications that might not function well. In some cases, one local computer can run the application correctly if that computer’s IP address is entered as the default DMZ server.WARNING!DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall and is exposed to exploits from the Internet. If compromised, the DMZ server computer can be used to attack other computers on your network.The router usually detects and discards incoming traffic from the Internet that is not a response to one of your local computers or a service that you have configured in the Port Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have the router forward the traffic to one computer on your network. This computer is called the default DMZ server.¾To set up a default DMZ server: 1. On the WAN Setup screen, select the Default DMZ Server check box.2. Type the IP address.3. Click Apply.
genie Advanced Home38Centria WNDR4700/WNDR4720 Change the MTU SizeThe maximum transmission unit (MTU) is the largest data packet a network device transmits. When one network device communicates across the Internet with another, the data packets travel through many devices along the way. If a device in the data path has a lower MTU setting than the other devices, the data packets have to be split or “fragmented” to accommodate the device with the smallest MTU. The best MTU setting for NETGEAR equipment is often just the default value. In some situations, changing the value fixes one problem but causes another. Leave the MTU unchanged unless one of these situations occurs:•You have problems connecting to your ISP or other Internet service, and the technical support of either the ISP or NETGEAR recommends changing the MTU setting. These web-based applications might require an MTU change:-A secure website that will not open, or displays only part of a web page-Yahoo email-MSN portal-America Online’s DSL service•You use VPN and have severe performance problems.•You used a program to optimize MTU for performance reasons, and now you have connectivity or performance problems.Note: An incorrect MTU setting can cause Internet communication problems. For instance, you might not be able to access certain websites, frames within websites, secure login pages, or FTP or POP servers.If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes away. The following table describes common MTU sizes and applications. Table 2. Common MTU sizes MTU Application1500 The largest Ethernet packet size and the default value.

Combined with the IP address, the IP subnet mask allows a device to know which other addresses are local to it, and which have to be reached through a gateway or router.•RIP Direction. Router Information Protocol (RIP) allows a router to exchange routing information with other routers. This setting controls how the router sends and receives RIP packets. Both is the default setting. With the Both or Out Only setting, the router broadcasts its routing table periodically. With the Both or In Only setting, the router incorporates the RIP information that it receives.•RIP Version. This setting controls the format and the broadcasting method of the RIP packets that the router sends. It recognizes both formats when receiving. By default, the RIP function is disabled. RIP-1 is universally supported. It is 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.Use Router as a DHCP Server This check box is usually selected so that the router functions as a Dynamic Host Configuration Protocol (DHCP) server.

Specify the end of the range for the pool of IP addresses in the same subnet as the router.Address ReservationWhen you specify a reserved IP address for a computer on the LAN, that computer receives the same IP address each time it accesses the router’s DHCP server. Assign reserved IP addresses to servers that require permanent IP settings. Use the Router as a DHCP ServerBy default, the router acts as a DHCP server. The router assigns IP, DNS server, and default gateway addresses to all computers connected to the LAN. The assigned default gateway address is the LAN address of the router. The router assigns IP addresses to the attached computers from a pool of addresses specified in this screen. 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. You can specify 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, define a range between 192.168.1.2 and 192.168.1.254, although you might want to save part of the range for devices with fixed addresses.The router delivers the following parameters to any LAN device that requests DHCP:•An IP address from the range you have defined•Subnet mask•Gateway IP address (the router’s LAN IP address)•Primary DNS server (if you entered a primary DNS address in the Internet Setup screen; otherwise, the router’s LAN IP address)•Secondary DNS server (if you entered a secondary DNS address in the Internet Setup screen)To use another device on your network as the DHCP server, or to specify the network settings of all of your computers, clear the Use Router as DHCP Server check box and click Apply. Otherwise, leave this check box selected. If this service is not enabled and no other DHCP server is available on your network, set your computers’ IP addresses manually or they will not be able to access the router.Address ReservationWhen you specify a reserved IP address for a computer on the LAN, that computer always receives the same IP address each time it accesses the router’s DHCP server. Reserved IP addresses should be assigned to computers or servers that require permanent IP settings.

Security69 Centria WNDR4700/WNDR4720Block Services (Port Filtering)Services are functions that server computers perform 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 the 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 at http://www.ietf.org/) 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 router already holds a list of many service port numbers, you are not limited to these choices. You can often determine port number information by contacting the publisher of the application, by asking user groups or newsgroups, or by searching.The Block Services screen lets you add and block specific Internet services by computers on your network. This is called service blocking or port filtering. To add a service for blocking, first determine which port number or range of numbers the application uses. ¾To block services:1.

A computer on any wireless or wired LAN segment of the router should be able to connect to the Internet or share files and printers with any other wireless or wired computer or server connected to the other access point.Port Forwarding and TriggeringBy default, the router blocks inbound traffic from the Internet to your computers except replies to your outbound traffic. You might need to create exceptions to this rule for these purposes:•To allow remote computers on the Internet to access a server on your local network. •To allow certain applications and games to work correctly when your router does not recognize their replies.Your router provides two features for creating these exceptions: port forwarding and port triggering. The next sections provide background information to help you understand how port forwarding and port triggering work, and the differences between the two.
Advanced Settings92Centria WNDR4700/WNDR4720 Remote Computer Access BasicsWhen a computer on your network needs to access a computer on the Internet, your computer sends your router a message containing the source and destination address and process information. Before forwarding your message to the remote computer, your router has to modify the source information and create and track the communication session so that replies can be routed back to your computer. Here is an example of normal outbound traffic and the resulting inbound responses:1. You open a browser, and your operating system assigns port number 5678 to this browser session. 2. You type http://www.example.com into the URL field, and your computer creates a web page request message with the following address and port information. The request message is sent to your router.Source address. Your computer’s IP address.Source port number. 5678, which is the browser session. Destination address. The IP address of www.example.com, which your computer finds by asking a DNS server.Destination port number. 80, which is the standard port number for a web server process.3. Your router creates an entry in its internal session table describing this communication session between your computer and the web server at www.example.com. Before sending the web page request message to www.example.com, your router stores the original information and then modifies the source information in the request message, performing Network Address Translation (NAT):•The source address is replaced with your router’s public IP address. This is necessary because your computer uses a private IP address that is not globally unique and cannot be used on the Internet.•The source port number is changed to a number chosen by the router, such as 33333. This is necessary because two computers could independently be using the same session number.Your router then sends this request message through the Internet to the web server at www.example.com.4. The web server at www.example.com composes a return message with the requested web page data. The return message contains the following address and port information. The web server then sends this reply message to your router.Source address. The IP address of www.example.com.Source port number. 80, which is the standard port number for a web server process.Destination address. The public IP address of your router.Destination port number. 33333.
Advanced Settings93 Centria WNDR4700/WNDR47205. Upon receiving the incoming message, your router checks its session table to determine whether there is an active session for port number 33333. Finding an active session, the router then modifies the message to restore the original address information replaced by NAT. Your router sends this reply message to your computer, which displays the web page from www.example.com. The message now contains the following address and port information.Source address. The IP address of www.example.com.Source port number. 80, which is the standard port number for a web server process.Destination address. Your computer’s IP address.Destination port number. 5678, which is the browser session that made the initial request.6. When you finish your browser session, your router eventually detects a period of inactivity in the communications. Your router then removes the session information from its session table, and incoming traffic is no longer accepted on port number 33333.Port Triggering to Open Incoming PortsIn the preceding example, requests are sent to a remote computer by your router from a particular service port number. Replies from the remote computer to your router are directed to that port number. If the remote server sends a reply to a different port number, your router does not recognize it and discards it. However, some application servers (such as FTP and IRC servers) send replies to multiple port numbers. Using the port triggering function of your router, you can tell the router to open additional incoming ports when a particular outgoing port originates a session.An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at destination port 6667. The IRC server not only responds to your originating source port, but also sends an “identify” message to your computer on port 113. Using port triggering, you can tell the router, “When you initiate a session with destination port 6667, you have to also allow incoming traffic on port 113 to reach the originating computer.” Using steps similar to the preceding example, the following sequence shows the effects of the port triggering rule you have defined:1. You open an IRC client program to start a chat session on your computer. 2. Your IRC client composes a request message to an IRC server using a destination port number of 6667, the standard port number for an IRC server process. Your computer then sends this request message to your router.3. Your router creates an entry in its internal session table describing this communication session between your computer and the IRC server. Your router stores the original information, performs Network Address Translation (NAT) on the source address and port, and sends this request message through the Internet to the IRC server. 4. Noting your port triggering rule and having observed the destination port number of 6667, your router creates an additional session entry to send any incoming port 113 traffic to your computer.
Advanced Settings94Centria WNDR4700/WNDR4720 5. The IRC server sends a return message to your router using the NAT-assigned source port (as in the previous example, say port 33333) as the destination port. The IRC server also sends an “identify” message to your router with destination port 113.6. Upon receiving the incoming message to destination port 33333, your router checks its session table to determine whether there is an active session for port number 33333. Finding an active session, the router restores the original address information replaced by NAT and sends this reply message to your computer.7. Upon receiving the incoming message to destination port 113, your router checks its session table and learns that there is an active session for port 113, associated with your computer. The router replaces the message’s destination IP address with your computer’s IP address and forwards the message to your computer.8. When you finish your chat session, your router eventually senses a period of inactivity in the communications. The router then removes the session information from its session table, and incoming traffic is no longer accepted on port numbers 33333 or 113.To configure port triggering, you need to know which inbound ports the application needs. Also, you need to know the number of the outbound port that will trigger the opening of the inbound ports. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups.Note: Only one computer at a time can use the triggered application.Port Forwarding to Permit External Host CommunicationsIn both of the preceding examples, your computer initiates an application session with a server computer on the Internet. However, you might need to allow a client computer on the Internet to initiate a connection to a server computer on your network. Normally, your router ignores any inbound traffic that is not a response to your own outbound traffic. You can configure exceptions to this default rule by using the port forwarding feature. A typical application of port forwarding can be shown by reversing the client-server relationship from the previous web server example. In this case, a remote computer’s browser needs to access a web server running on a computer in your local network. Using port forwarding, you can tell the router, “When you receive incoming traffic on port 80 (the standard port number for a web server process), forward it to the local computer at 192.168.1.123.” The following sequence shows the effects of the port forwarding rule you have defined:1. The user of a remote computer opens a browser and requests a web page from www.example.com, which resolves to the public IP address of your router. The remote computer composes a web page request message with the following destination information: Destination address. The IP address of www.example.com, which is the address of your router.Destination port number. 80, which is the standard port number for a web server process.
Advanced Settings95 Centria WNDR4700/WNDR4720The remote computer then sends this request message through the Internet to your router.2. Your router receives the request message and looks in its rules table for any rules covering the disposition of incoming port 80 traffic. Your port forwarding rule specifies that incoming port 80 traffic should be forwarded to local IP address 192.168.1.123. Therefore, your router modifies the destination information in the request message:The destination address is replaced with 192.168.1.123.Your router then sends this request message to your local network.3. Your web server at 192.168.1.123 receives the request and composes a return message with the requested web page data. Your web server then sends this reply message to your router.4. Your router performs NAT on the source IP address, and sends this request message through the Internet to the remote computer, which displays the web page from www.example.com.To configure port forwarding, you need to know which inbound ports the application needs. You usually can determine this information by contacting the publisher of the application or the relevant user groups and newsgroups.How Port Forwarding Differs from Port TriggeringThe following points summarize the differences between port forwarding and port triggering:•Port triggering can be used by any computer on your network, although only one computer can use it at a time.•Port forwarding is configured for a single computer on your network.•Port triggering does not require that you know the computer’s IP address in advance. The IP address is captured automatically.•Port forwarding requires that you specify the computer’s IP address during configuration, and the IP address can never change.•Port triggering requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a period of no activity.•Port forwarding is always active and does not need to be triggered.Set Up Port Forwarding to Local ServersUsing the port forwarding feature, you can allow certain types of incoming traffic to reach servers on your local network. For example, you might want to make a local web server, FTP server, or game server visible and available to the Internet.Use the Port Forwarding screen to configure the router to forward specific incoming protocols to computers on your local network. In addition to servers for specific applications, you can also specify a default DMZ server to which all other incoming protocols are forwarded.
Advanced Settings96Centria WNDR4700/WNDR4720 Before starting, determine which type of service, application, or game you want to provide. Find out the local IP address of the computer that will provide the service. The server computer has to always have the same IP address.¾To set up port forwarding:Tip: To ensure that your server computer always has the same IP address, use the reserved IP address feature of your Centria. 1. Select Advanced Setup > Port Forwarding/Port Triggering to display the following screen:FOR POSITION ONLYPort Forwarding is selected as the service type.2. From the Service Name list, select the service or game that you will host on your network. If the service does not appear in the list, see Add a Custom Service on page 96.3. In the corresponding Server IP Address field, enter the last digit of the IP address of your local computer that will provide this service. 4. Click Add. The service appears in the list in the screen.Add a Custom ServiceTo define a service, game, or application that does not appear in the Service Name list, first determine which port number or range of numbers the application uses. You can usually get this information by contacting the publisher of the application or user groups or newsgroups. ¾To add a custom service:1. Select Advanced > Advanced Setup > Port Forwarding/Port Triggering.2. Select Port Forwarding as the service type.

In the Service Type list, select the protocol. If you are unsure, select TCP/UDP.6. Specify the port settings: •External Starting Port and External Ending Port. These are the starting number and ending number for the public ports at the Internet interface. For single port forwarding, number in the External Starting Port and External Ending Port fields can be the same. The range is from 1 to 65534.•Use the same port range for Internal port. This checkbox is selected by default. If you want to use different ports, clear this check box and specify the internal ports.•Internal Starting Port and Internal Ending Port. These are the starting number and ending number for the ports of a computer on the router’s local area network (LAN). These are private ports. The router calculates the internal ending port.7. In the Internal IP Address field, enter the IP address of your local computer that will provide this service.8. Click Apply. The service appears in the list in the Port Forwarding/Port Triggering screen.Edit or Delete a Port Forwarding Entry¾To edit or delete a port forwarding entry:1. In the table, select the radio button next to the service name.2. Click Edit Service or Delete Service.Application Example: Making a Local Web Server PublicIf you host a web server on your local network, you can use port forwarding to allow web requests from anyone on the Internet to reach your web server.
Advanced Settings98Centria WNDR4700/WNDR4720 ¾To make a local web server public:1. Assign your web server either a fixed IP address or a dynamic IP address using DHCP address reservation. In this example, your router always gives your web server an IP address of 192.168.1.33. 2. In the Port Forwarding/Port Triggering screen, configure the router to forward the HTTP service to the local address of your web server at 192.168.1.33. HTTP (port 80) is the standard protocol for web servers.3. (Optional) Register a host name with a Dynamic DNS service, and configure your router to use the name as described in Dynamic DNS on page 100. To access your web server from the Internet, a remote user has to know the IP address that your ISP assigned. However, if you use a Dynamic DNS service, the remote user can reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org.Set Up Port TriggeringPort triggering is a dynamic extension of port forwarding that is useful in these cases:•More than one local computer needs port forwarding for the same application (but not simultaneously).•An application needs to open incoming ports that are different from the outgoing port.When port triggering is enabled, the router monitors outbound traffic looking for a specified outbound “trigger” port. When the router detects outbound traffic on that port, it remembers the IP address of the local computer that sent the data. The router then temporarily opens the specified incoming port or ports, and forwards incoming traffic on the triggered ports to the triggering computer. While port forwarding creates a static mapping of a port number or range to a single local computer, port triggering can dynamically open ports to any computer that needs them and can close the ports when they are no longer needed.Note: If you use applications such as multiplayer gaming, peer-to-peer connections, real-time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should also enable Universal Plug and Play (UPnP) according to the instructions in Universal Plug and Play on page 105.To set up port triggering, you need to know which inbound ports the application needs and the number of the outbound port that will trigger the opening of the inbound ports. You can usually get this information by contacting the publisher of the application or user groups or newsgroups.
Advanced Settings99 Centria WNDR4700/WNDR4720¾To set up port triggering: 1. Select Advanced > Advanced Setup > Port Forwarding/Port Triggering.2. Select the Port Triggering radio button to display the port triggering information.FOR POSITION ONLY3. Clear the Disable Port Triggering check box if it is selected.Note: If the Disable Port Triggering check box is selected after you configure port triggering, port triggering is disabled. However, any port triggering configuration information you added to the router is retained even though it is not used.4. In the Port Triggering Timeout field, enter a value up to 9999 minutes. 5. This value controls the inactivity timer for the designated inbound ports. The inbound ports close when the inactivity time expires. This is required because the router cannot be sure when the application has terminated.
Advanced Settings100Centria WNDR4700/WNDR4720 6. Click Add Service to display the following screen: 7. In the Service Name field, type a descriptive service name. 8. In the Service User list, select Any (the default) to allow this service to be used by any computer on the Internet. Otherwise, select Single address, and enter the IP address of one computer to restrict the service to a particular computer. 9. Select the service type, either TCP or UDP or both (TCP/UDP). If you are not sure, select TCP/UDP.10. In the Triggering Port field, enter the number of the outbound traffic port that will cause the inbound ports to be opened. 11. Enter the inbound connection port information in the Connection Type, Starting Port, and Ending Port fields.12. Click Apply. The service appears in the Port Triggering Portmap Table. Dynamic DNSIf your Internet service provider (ISP) gave you 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 do 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. This type of service lets you register your domain to their IP address and forwards traffic directed at your domain to your frequently changing IP address.If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic DNS service does not work because private addresses are not routed on the Internet.Your router contains a client that can connect to the Dynamic DNS service provided by DynDNS.org. First visit their website at http://www.dyndns.org and obtain an account and
Advanced Settings101 Centria WNDR4700/WNDR4720host name that you configure in the router. Then, whenever your ISP-assigned IP address changes, your router automatically contacts the Dynamic DNS service provider, logs in to your account, and registers your new IP address. If your host name is hostname, for example, you can reach your router at http://hostname.dyndns.org.On the Advanced tab, select Advanced Setup > Dynamic DNS to display the following screen:FOR POSITION ONLYFigure 10. Forward traffic to a changing IP address¾To set up Dynamic DNS:1. Register for an account with one of the Dynamic DNS service providers whose names appear in the Service Provider list. For example, for DynDNS.org, select www.dyndns.org.2. Select the Use a Dynamic DNS Service check box. 3. Select the name of your Dynamic DNS service provider. 4. Type the host name (or domain name) that your Dynamic DNS service provider gave you.5. Type the user name for your Dynamic DNS account. This is the name that you use to log in to your account, not your host name.6. Type the password (or key) for your Dynamic DNS account. 7. 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 causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org.8. Click Apply to save your configuration.
Advanced Settings102Centria WNDR4700/WNDR4720 Static RoutesStatic routes provide additional routing information to your router. Typically, you do not need to add static routes. You have to configure static routes only for unusual cases such as multiple routers or multiple IP subnets on your network.As 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 192.168.1.100.•Your company’s network address 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 gateway, and a second static route was created to your local network for all 192.168.1.x addresses. With this configuration, if you attempt to access a device on the 134.177.0.0 network, your router forwards your request to the ISP. The ISP forwards your request to the company where you are employed, and the request is likely to be denied by the company’s firewall.In this case you have to define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.1.100. 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 Gateway IP Address field specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.1.100. •A metric value of 1 will work since the ISDN router is on the LAN. •Private is selected only as a precautionary security measure in case RIP is activated.
Advanced Settings103 Centria WNDR4700/WNDR4720¾To set up a static route:1. Select Advanced > Advanced Setup > Static Routes, and click Add to display the following screen:FOR POSITION ONLY2. In the Route Name field, type a name for this static route (for identification purposes only.) 3. Select the Private check box if you want to limit access to the LAN only. If Private is selected, the static route is not reported in RIP. 4. Select the Active check box to make this route effective. 5. Type the IP address of the final destination. 6. Type the IP subnet mask for this destination. If the destination is a single host, type 255.255.255.255. 7. Type the gateway IP address, which has to be a router on the same LAN segment as the Centria. 8. Type a number from 1 through 15 as the metric value. This value represents the number of routers between your network and the destination. Usually, a setting of 2 or 3 works, but if this is a direct connection, set it to 1. 9. Click Apply to add the static route.
Advanced Settings104Centria WNDR4700/WNDR4720 Remote ManagementThe remote management feature lets you upgrade or check the status of your Centria over the Internet.¾To set up remote management:1. Select Advanced > Advanced Setup > Remote Management. FOR POSITION ONLYNote: Be sure to change the router’s default login password to a secure password. The ideal password contains no dictionary words from any language and contains upper-case and lower-case letters, numbers, and symbols. It can be up to 30 characters.2. Select the Turn Remote Management On check box.3. Under Allow Remote Access By, specify the external IP addresses to be allowed to access the router’s remote management.Note: For enhanced security, restrict access to as few external IP addresses as practical.•To allow access from a single IP address on the Internet, select Only This Computer. Enter the IP address that will be allowed access. •To allow access from a range of IP addresses on the Internet, select IP Address Range. Enter a beginning and ending IP address to define the allowed range. •To allow access from any IP address on the Internet, select Everyone. 4. Specify the port number for accessing the management interface.
Advanced Settings105 Centria WNDR4700/WNDR4720Normal web browser access uses the standard HTTP service port 80. For greater security, enter a custom port number for the remote web management interface. Choose a number from 1024 to 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP.5. Click Apply to have your changes take effect.6. When accessing your router from the Internet, type your router’s WAN IP address into your browser’s address or location field followed by a colon (:) and the custom port number. For example, if your external address is 134.177.0.123 and you use port number 8080, enter http://134.177.0.123:8080 in your browser.USB SettingsFor added security, the router can be set up to share only approved USB devices. See Specify Approved USB Devices on page 56 for the procedure.Universal Plug and PlayUniversal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, to access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications such as instant messaging or remote assistance (a feature in Windows XP), you should enable UPnP.¾To turn on Universal Plug and Play:1. Select Advanced > Advanced Setup > UPnP. The UPnP screen displays. FOR POSITION ONLY2. The available settings and information in this screen are:
Advanced Settings106Centria WNDR4700/WNDR4720 Turn UPnP On. UPnP can be enabled or disabled for automatic device configuration. The default setting for UPnP is disabled. If this check box is not selected, the router does not allow any device to automatically control the resources, such as port forwarding (mapping) of the router. Advertisement Period. The advertisement period is how often the router broadcasts its UPnP information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. Shorter durations ensure that control points have current device status at the expense of additional network traffic. Longer durations can compromise the freshness of the device status, but can significantly reduce network traffic.Advertisement Time to Live. The time to live for the advertisement is measured in hops (steps) for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to 255. The default value for the advertisement time to live is 4 hops, which is fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it might be necessary to increase this value.UPnP Portmap Table. The UPnP Portmap Table displays the IP address of each UPnP device that is currently accessing the router and which ports (internal and external) that device has opened. The UPnP Portmap Table also displays what type of port is open and whether that port is still active for each IP address. 3.

This button turns the wireless radios in the router on and off. The Wireless LEDs are lit when the wireless radio is turned on.The Push 'N' Connect (WPS) Button Blinks AmberIf after using the WPS function the button blinks amber, check the following:•Make sure that you are using the button and not the router’s built-in registrar.•Check that PIN verification has succeeded for the wireless device you are adding to the wireless network.•Make sure that you have not pressed the WPS button on the side of the router after disabling the WPS feature (you logged in to the router and disabled this previously).•Check that the router is not in the temporary AP setup locked state (if you are using the wireless repeater function).
Troubleshooting113 Centria WNDR4700/WNDR4720Cannot Log In to the RouterIf you are unable to log in to the router 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 that 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 192.168.1.2 to 192.168.1.254. •If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and Mac OS 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 sets the router’s IP address to 192.168.1.1. This procedure is explained in Factory Settings on page 119.•Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure that the Java applet is loaded.•Try quitting the browser and launching it again.•Make sure that 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 you enter this information.•If you are attempting to set up your NETGEAR router as an additional router behind an existing router in your network, consider replacing the existing router. NETGEAR does not support such a configuration.•If you are attempting to set up your NETGEAR router as a replacement for an ADSL gateway in your network, the router cannot perform many gateway services. For example, the router cannot convert ADSL or cable data into Ethernet networking information. NETGEAR does not support such a configuration.Cannot Access the InternetIf you can access your router but not the Internet, check to see if the router can obtain an IP address from your Internet service provider (ISP). Unless your ISP provides a fixed IP address, your router requests an IP address from the ISP. You can determine whether the request was successful using the Router Status screen.¾To check the WAN IP address: 1. Start your browser, and select an external site such as www.netgear.com.2. Access the router interface at www.routerlogin.net.3. Select Administration > Router Status.
Troubleshooting114Centria WNDR4700/WNDR4720 4. Check that an IP address is shown for the Internet port. If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.If your router cannot obtain an IP address from the ISP, you might need to force your cable or DSL modem to recognize your new router by restarting your network, as described in Sequence to Restart Your Network on page 110.If your router is still unable to obtain an IP address from the ISP, the problem might be one of the following:•Your Internet service provider (ISP) might require a login program. Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.•If your ISP requires a login, the login name and password might be set incorrectly.•Your ISP might check for your computer’s host name. Assign the computer host name of your ISP account as the account name in the Internet Setup screen.•Your ISP allows only one Ethernet MAC address to connect to Internet and might check for your computer’s MAC address. In this case, do one of the following:-Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.-Configure your router to clone your computer’s MAC address.If your router can obtain an IP address, but your computer is unable to load any web pages from the Internet:•Your computer might not recognize any DNS server addresses. A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically, your ISP provides the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, reboot your computer, and verify the DNS address.You can configure your computer manually with DNS addresses, as explained in your operating system documentation.•Your computer might not have the router configured as its TCP/IP gateway.If your computer obtains its information from the router by DHCP, reboot the computer, and verify the gateway address.•You might be running login software that is no longer needed.If your ISP provided a program to log you in to the Internet (such as WinPoET), you no longer need to run that software after installing your router. You might need to go to Internet Explorer and select Tools > Internet Options, click the Connections tab, and select Never dial a connection.

(By default, SSID broadcast is enabled.)•Does your wireless device support the security that you are using for your wireless network (WPA or WPA2)?•If you want to view the wireless settings for the router, use an Ethernet cable to connect a computer to a LAN port on the router. Then log in to the router, and select Wireless (see (Basic Wireless Settings on page 28). Note: Be sure to click Apply if you make changes.Wireless Signal StrengthIf your wireless device finds your network, but the signal strength is weak, check these conditions:•Is your router too far from your computer, or too close? Place your computer near the router, but at least 6 feet away, and see whether the signal strength improves.•Is your wireless signal blocked by objects between the router and your computer?
Troubleshooting117 Centria WNDR4700/WNDR4720Restore the Factory Settings and PasswordThis section explains how to restore the factory settings, changing the router’s administration password back to password. You can erase the current configuration and restore factory defaults in two ways:•Use the Erase function of the router (see Erase on page 81).•Use the Reset button on the back of the router. See Factory Settings on page 119. If you restore the factory settings and the router fails to restart, or the green Power LED continues to blink, the unit might be defective. If the error persists, you might have a hardware problem and should contact technical support at http://www.netgear.com/support.Troubleshoot Your Network Using the Ping UtilityMost network 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. You can easily troubleshooting a network by using the ping utility in your computer or workstation. Test 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.¾To ping the router from a running Windows PC:1. From the Windows toolbar, click Start, and then select Run.2. In the field provided, type ping followed by the IP address of the router, as in this example:ping www.routerlogin.net3. 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 outIf the path is not functioning correctly, you could have one of the following problems:•Wrong physical connectionsFor a wired connection, make sure that the numbered LAN port LED is on for the port to which you are connected.
Troubleshooting118Centria WNDR4700/WNDR4720 Check that the appropriate LEDs are on for your network devices. If your router and computer are connected to a separate Ethernet switch, make sure that the link LEDs are on for the switch ports that are connected to your computer and router.•Wrong network configurationVerify that the Ethernet card driver software and TCP/IP software are both installed and configured on your computer. Verify that the IP address for your router and your computer are correct and that the addresses are on the same subnet.Test the Path from Your Computer to a Remote DeviceAfter verifying that the LAN path works correctly, test the path from your computer to a remote device.1. From the Windows toolbar, click the Start button, and then select Run.2. In the Windows Run window, 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 like those shown in the previous section are displayed.If you do not receive replies:•Check that your computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information is not visible in your computer’s Network Control Panel. Verify that the IP address of the router is listed as the default gateway.•Check to see that the network address of your computer (the portion of the IP address specified by the subnet mask) 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 computer, enter that host name as the account name in the Internet Setup screen.•Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers.Many broadband ISPs restrict access by allowing traffic only from the MAC address of your broadband modem. Some ISPs additionally restrict access to the MAC address of a single computer connected to that modem. If this is the case, configure your router to “clone” or “spoof” the MAC address from the authorized computer.
