Chapter 3. Wireless Settings | 2433. Wireless SettingsThis chapter describes how to use the Wireless Settings screens to view and change (if needed) your wireless network settings. Security features to prevent objectionable content from reaching your PCs are covered in Chapter 4, Content Filtering Settings. This chapter contains the following sections:•Wireless Security Compatibility •Security Basics •Add Clients (Computers or Devices) to Your Network •Wireless Settings Screen •Wireless Guest Networks

Chapter 3. Wireless Settings | 25N600 Wireless Dual Band Gigabit Router WNDR3700v4 User Manual Wireless Security CompatibilityA wireless client is the wireless device or computer that will connect to your router. Most PCs and laptops come with a wireless adapter installed, but if it is outdated or slow, you can purchase a new wireless USB adapter to plug into a USB port. Make sure the wireless adapter in each client in your wireless network supports WPA or WPA2 wireless security. Note: If you connect devices to your router using WPS as described in Wi-Fi Protected Setup (WPS) Method on page 26, those devices assume the security settings of the router.Security BasicsUnlike wired network data, wireless data transmissions extend beyond your walls and can be received by any device with a compatible wireless adapter (radio). For this reason, it is very important to use the security features available to you. Your router has the security features described here and in Chapter 4, Content Filtering Settings.•Wireless security options•Turn off wireless connectivity•Disable SSID broadcast•Restrict access by MAC addressWireless Security OptionsA security option is the type of security protocol applied to your wireless network. The security protocol encrypts data transmissions and ensures that only trusted devices receive authorization to connect to your network. There are several types of encryption. WPA2 is the latest and most secure, and is recommended if your equipment supports it. WPA has several options including pre-shared key (PSK) encryption and 802.1x encryption for enterprises. Note that it is also possible to use your router without wireless security. NETGEAR does not recommend this. You can view or change the wireless security options in the Wireless Settings screen. See Wireless Settings Screen on page 28.Turn Off Wireless ConnectivityYou can turn off the wireless connectivity of the router by pressing the Wireless On/Off button on its front panel. For example, if you use your laptop 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 through Ethernet cables can still use the router.

26 | Chapter 3. Wireless Settings N600 Wireless Dual Band Gigabit Router WNDR3700v4 User Manual Disable SSID BroadcastBy default, the router broadcasts its Wi-Fi network name (SSID) so devices can find it. If you change this setting to not allow the broadcast, wireless devices will not find your router unless they are configured with the same SSID. Note: Turning off SSID broadcast nullifies the wireless network discovery feature of some products such as Windows XP, but the data is still fully exposed to a determined snoop using specialized test equipment like wireless sniffers. If you allow the broadcast, be sure to keep wireless security enabled.Restrict Access by MAC AddressYou can enhance your network security by allowing access to only specific PCs based on their Media Access Control (MAC) addresses. You can restrict access to only trusted PCs so that unknown PCs cannot wirelessly connect to the router. The wireless station MAC address filtering adds additional security protection to the wireless security option that you have in force. The access list determines which wireless hardware devices are allowed to connect to the router by MAC address. See Advanced Wireless Settings on page 74 for the procedure.Add Clients (Computers or Devices) to Your NetworkChoose either the manual or the WPS method to add wireless computers or devices to your wireless network.Manual Method1. Open the software that manages your wireless connections on the wireless device (laptop computer, gaming device, iPhone) that you want to connect to your router. This software scans for all wireless networks in your area.2. Look for your network and select it. If you did not change the name of your network during the setup process, look for the default Wi-Fi network name (SSID) and select it. The default Wi-Fi network name (SSID) is located on the product label on the bottom of the router.3. Enter the router passphrase and click Connect. The default router passphrase is located on the product label on the bottom of the router.4. Repeat steps 1–3 to add other wireless devices.Wi-Fi Protected Setup (WPS) MethodWi-Fi Protected Setup (WPS) is a standard that lets you easily join a secure wireless network with WPA or WPA2 wireless security. The router automatically sets security for each

This is relevant when the log is sent weekly.-Time specifies the time of day to send the log. This is relevant when the log is sent daily or weekly.Note: If the Weekly, Daily, or Hourly option is selected and the log fills up before the specified period, the log is automatically emailed to the specified email address. After the log is sent, it is cleared from the router’s memory. If the router cannot email the log file, the log buffer might fill up. In this case, the router overwrites the log and discards its contents.Port ForwardingBecause the router 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, with port forwarding you can make a local server (for example, a Web server or game server) visible and available to the Internet. Note: Some residential broadband ISP accounts do not let you run server processes (such as a Web or FTP server) from your location. Your ISP might periodically check for servers and 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.Port forwarding tells the router to direct inbound traffic for a particular service to one local server based on the destination port number. Port forwarding opens holes in your firewall. Enable only those ports that are necessary for your network. Before starting, you need to determine which type of service, application, or game you will provide, and the local IP address of the computer that will provide the service. Be sure the computer’s IP address never changes.The following are some considerations for port forwarding:•If your external IP address is assigned dynamically by your ISP, the IP address might change periodically as the DHCP lease expires. Consider using the Dynamic DNS screen described in Dynamic DNS so that external users can always find your network.•If the IP address of the local server computer is assigned by DHCP, it might change when the computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN Setup screen to keep the computer’s IP address constant.

Chapter 4. Content Filtering Settings | 43N600 Wireless Dual Band Gigabit Router WNDR3700v4 User Manual •Local computers access the local server using the computer’s local LAN address. Attempts by local computers to access the server using the external WAN IP address fail.To configure port forwarding to a local server:1. Select Advanced > Port Forwarding/Port Triggering.2. Select the Port Forwarding radio button as the service type as shown in the following figure:3. 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, you can add a custom service as described in the following section..4. In the Server IP Address field, enter the last digit of the IP address of your local computer that will provide this service. 5. Click Add. The service appears in the list in the screen.Note: To edit or delete a port forwarding entry in the table, select the button next to the service name and click Edit Service or DeleteService.Add a Custom ServiceTo define a service, game, or application that does not appear in the Service Name list, you need to know which port number or range of numbers is used by the application. You can usually find out by contacting the publisher of the application or user groups or newsgroups.

44 | Chapter 4. Content Filtering Settings N600 Wireless Dual Band Gigabit Router WNDR3700v4 User Manual To add a custom service:1. On the Port Triggering screen, click the Add Custom Service button. The following screen displays:2. In the Service Name field, enter a descriptive name. 3. In the Protocol field, select the protocol. If you are unsure, select TCP/UDP.4. In the Starting Port field, enter the first port number. •If the application uses only a single port, enter the same port number in the Ending Port field.•If the application uses a range of ports, enter the ending port number of the range in the Ending Port field.5. In the Server IP Address field, enter the IP address of your local computer that will provide this service.6. Click Apply. The service appears in the list in the Port Forwarding/Port Triggering screen.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. To 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, as explained in IP Address Reservation on page 72. In this example, your router will always give your Web server an IP address of 192.168.1.33. 2. In the Port Forwarding 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 70. To access your Web server from the Internet, a remote user needs to know the IP address that has been assigned by your ISP. However, if you use a Dynamic DNS

Chapter 4. Content Filtering Settings | 45N600 Wireless Dual Band Gigabit Router WNDR3700v4 User Manual service, the remote user can reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org.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 80.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.To set up port triggering: 1.Select Advanced > Port Forwarding/Port Triggering. The Forwarding/Port Triggering screen displays.

46 | Chapter 4. Content Filtering Settings N600 Wireless Dual Band Gigabit Router WNDR3700v4 User Manual 2. Select the Port Triggering radio button. The port triggering information displays.3. Clear the Disable Port Triggering check box.If you set up port triggering and then select the Disable Port Triggering check box, port triggering is disabled, but the port triggering set up is retained even though it is not used.4. In the Port Triggering Timeout field, enter a value up to 9999 minutes. 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.5. Click Add Service to display the following screen: 6. In the Service Name field, type a descriptive service name. 7. In the Service User field, 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. 8. Select the service type, either TCP or UDP or both (TCP/UDP). If you are not sure, select TCP/UDP.9. In the Triggering Port field, enter the number of the outbound traffic port that will cause the inbound ports to be opened.
