2-1v1.0, July 2009Chapter 2Safeguarding Your NetworkFor a wireless connection, the SSID, also called the wireless network name, and the wireless security setting must be the same for the wireless router and wireless computers or wireless adapters. NETGEAR strongly recommends that you use wireless security. This chapter includes:•“Planning Your Wireless Network•“Manually Configuring Your Wireless Settings” on page 2-4•“Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-12•“Connecting Additional Wireless Client Devices After WPS Setup” on page 2-17•“Restricting Access to Your Router” on page 2-19 Planning Your Wireless NetworkFor compliance and compatibility between similar products in your area, the operating channel and region must be set correctly. To configure the wireless network, you can either specify the wireless settings, or you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/WPA2 security.• To manually configure the wireless settings, you must know the following:– SSID. The default SSID for the wireless router is NETGEAR. Warning: Computers can connect wirelessly at a range of several hundred feet. This can allow others outside of your immediate area to access your network.Note: For information about restricting access to USB storage devices, see “Configuring USB Storage Advanced Settings” on page 7-7.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 2-2 Safeguarding Your Networkv1.0, July 2009– The wireless mode (802.11g, or 802.11b) that each wireless adapter supports.– Wireless security option. To successfully implement wireless security, check each wireless adapter to determine which wireless security option it supports. See “Manually Configuring Your Wireless Settings” on page 2-4.• Push 'N' Connect (WPS) automatically implements wireless security on the wireless router while, at the same time, allowing you to automatically implement wireless security on any WPS-enabled devices (such as wireless computers and wireless adapter cards). You activate WPS by pressing a WPS button on the wireless router, clicking an onscreen WPS button, or entering a PIN number. This generates a new SSID and implements WPA/WPA2 security.To set up your wireless network using the WPS feature:– Use the WPS button on the side of the wireless router (there is also an onscreen WPS button), or enter the PIN of the wireless device. – Make sure that all wireless computers and wireless adapters on the network are Wi-Fi certified and WPA or WPA 2 capable, and that they support WPS configuration.See “Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-12.Wireless Placement and Range GuidelinesThe range of your wireless connection can vary significantly based on the physical placement of the wireless router. The latency, data throughput performance, and notebook power consumption of wireless adapters also vary depending on your configuration choices.For best results, place your wireless router according to the following guidelines:• Near the center of the area in which your PCs will operate.• In an elevated location such as a high shelf where the wirelessly connected PCs have line-of-sight access (even if through walls).• Away from sources of interference, such as PCs, microwave ovens, and 2.4 GHz cordless phones.• Away from large metal surfaces.Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup (WPS) standard (for more information, see http://www.wi-fi.org). All other Wi-Fi-certified and WPS-capable products should be compatible with NETGEAR products that implement Push 'N' Connect.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Safeguarding Your Network 2-3v1.0, July 2009• Put the antenna in a vertical position to provide the best side-to-side coverage. Put the antenna in a horizontal position to provide the best up-and-down coverage. • If using 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 5 channels (for example, use Channels 1 and 6, or 6 and 11).The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer.Wireless Security OptionsIndoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300 feet. Such distances can allow for others outside your immediate area to access your network.Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The WNDR3700 router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.There are several ways you can enhance the security of your wireless network:•WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption block all but the most determined eavesdropper. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK. Figure 2-1Wireless data1) Open system: easy but no security.2) WEP: security, but some performance 3) WPA-PSK: strong security.4) WPA2-PSK: very strong security.impact.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 2-12 Safeguarding Your Networkv1.0, July 2009Using Push 'N' Connect (WPS) to Configure Your Wireless NetworkIf your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure the wireless router’s SSID and security settings and, at the same time, connect the wireless client securely and easily to the wireless router. Look for the symbol on your client device (computers that will connect wirelessly to the wireless router are clients). WPS automatically configures the network name (SSID) and wireless security settings for the wireless router (if the wireless router is in its default state) and broadcasts these settings to the wireless client.Some considerations regarding WPS are:• WPS supports only WPA-PSK and WPA2-PSK wireless security. WEP security is not supported by WPS.• If your wireless network will include a combination of WPS capable devices and non-WPS capable devices, NETGEAR suggests that you set up your wireless network and security settings manually first, and use WPS only for adding additional WPS capable devices. See “Adding Both WPS and Non-WPS Clients” on page 2-17.A WPS client can be added using the Push Button method or the PIN method.•Using the Push Button. This is the preferred method. See the following section, “Using a WPS Button to Add a WPS Client.•Entering a PIN. For information about using the PIN method, see “Using PIN Entry to Add a WPS Client” on page 2-14.Using a WPS Button to Add a WPS ClientAny wireless computer or wireless adapter that will connect to the wireless router wirelessly is a client. The client must support a WPS button, and must have a WPS configuration utility, such as the NETGEAR Smart Wizard or Atheros Jumpstart.To use the wireless router WPS button to add a WPS client: Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup (WPS) standard (for more information, see http://www.wi-fi.org). All other Wi-Fi-certified and WPS-capable products should be compatible with NETGEAR products that implement Push 'N' Connect.

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 router.RIP Direction RIP (Router Information Protocol) allows a wireless router to exchange routing information with other routers. This setting controls how the wireless router sends and receives RIP packets. Both is the default. •Both or Out Only. The wireless router broadcasts its routing table periodically. •Both or In Only. The wireless router incorporates the RIP information that it receives. •None. The wireless router 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 router sends. It recognizes both formats when receiving. By default, this is RIP-1. • 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.DHCP ServerFor more informationUse Router as a DHCP ServerThis check box is usually selected so that the wireless router functions as a Dynamic Host Configuration Protocol (DHCP) server. See “Using the Router as a DHCP Server” on page 5-4.Starting IP Address Specify the start of the range for the pool of IP addresses in the same subnet as the wireless router.Ending IP Address Specify the end of the range for the pool of IP addresses in the same subnet as the wireless router.Address ReservationFor more information, see “Address Reservation” on page 5-4.When you specify a reserved IP address for a computer on the LAN, that computer receives the same IP address each time it access the router’s DHCP server. Assign reserved IP addresses to servers that require permanent IP settings. Table 5-1. LAN SetupSettings Description

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-4 Customizing Your Network Settingsv1.0, July 2009Using the Router as a DHCP ServerBy default, the router functions as a DHCP server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the router’s 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. Click the link to the online document “TCP/IP Networking Basics” in Appendix B for an explanation of DHCP and information about how to assign IP addresses for your network. 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, you should define a range between 192.168.1.2 and 192.168.1.254, although you might wish 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 Basic Settings screen; otherwise, the router’s LAN IP address)• Secondary DNS Server (if you entered a secondary DNS address in the Basic Settings screen)To use another device on your network as the DHCP server, or to manually configure the network settings of all of your computers, clear the Use Router as DHCP Server check box. Otherwise, leave it selected. If this service is not selected and no other DHCP server is available on your network, you will need to 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. To reserve an IP address: 1. Click Add.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-5v1.0, July 20092. In the IP Address field, type the IP address to assign to the computer or server. (Choose an IP address from the router’s LAN subnet, such as 192.168.1.x.) 3. Type the MAC address of the computer or server.4. Click Apply to enter the reserved address into the table. To edit or delete a reserved address entry: 1. Select the radio button next to the reserved address you want to edit or delete. 2. Click Edit or Delete.Using a Dynamic DNS ServiceIf 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, which allows you to register your domain to their IP address, and forwards traffic directed at your domain to your frequently changing IP address.Your router contains a client that can connect to the Dynamic DNS service provided by DynDNS.org. You must first visit their website at www.dyndns.org and obtain an account and host name, which you configure in the router. Then, whenever your ISP-assigned IP address changes, Tip: If the computer is already present on your network, you can copy its MAC address from the Attached Devices screen and paste it here.Note: The reserved address is not 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.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 are not routed on the Internet.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-6 Customizing Your Network Settingsv1.0, July 2009your 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 hostname.dyndns.org.From the main menu, under Advanced, select Dynamic DNS to display the Dynamic DNS screen.To configure Dynamic DNS:1.

From the main menu, under Advanced, click WAN Setup to view the WAN Setup screen. The WAN Setup fields are described in the following table:Figure 5-3Table 5-2. WAN Setup SettingsSetting DescriptionDisable SPI Firewall The Stateful Packet Inspection (SPI) firewall protects your network and computers against attacks and intrusions. A stateful packet firewall carefully inspects incoming traffic packets, looking for known exploits such as malformed, oversized, or out-of-sequence packets. The firewall should be disabled only in special circumstances, such as when you are troubleshooting application issues. Default DMZ Server This feature is sometimes helpful when you are using some online games and videoconferencing. Be careful when using this feature because it makes the firewall security less effective. See the following section, Configuring Static Routes.Respond to Ping on Internet WAN PortIf you want the wireless router to respond to a ping from the Internet, select this check box. This should be used only as a diagnostic tool, since it allows your wireless router to be discovered. Do not select this check box unless you have a specific reason to do so.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 “Changing the MTU Size” on page 6-6.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-8 Customizing Your Network Settingsv1.0, July 2009Setting Up a 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.Incoming traffic from the Internet is usually discarded by the router unless the traffic is 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 it forwarded to one computer on your network. This computer is called the default DMZ server.The WAN Setup screen lets you configure a default DMZ server.To assign a computer or server to be a default DMZ server: 1. In the last Default DMZ Server field, type the last digit of the IP address for that computer. To remove the default DMZ server, enter 0 (zero).2. Select the Default DMZ Server check box, and click Apply.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. 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.Table 5-2. WAN Setup SettingsSetting Description

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-9v1.0, July 2009Configuring Static RoutesStatic routes provide additional routing information to your router. Under usual 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.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 must 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.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-10 Customizing Your Network Settingsv1.0, July 2009Select Static Routes under Advanced in the main menu. The Static Routes screen displays.To add or edit a static route:1. Click Add to open the Static Routes screen. 2. In the Route Name field, type a name for this static route. (This is 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 destination 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 must be a router on the same LAN segment as the WNDR3700 router. Figure 5-4Figure 5-5

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-11v1.0, July 20098. Type a number between 1 and 15 as the metric value. This 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 have the static route entered into the table. Allowing Inbound Connections to Your NetworkBy default, the WNDR3700 router blocks any inbound traffic from the Internet to your computers except for replies to your outbound traffic. However, you might need to create exceptions to this rule for the following 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 their replies are not recognized by your router.Your router provides two features for creating these exceptions: port forwarding and port triggering. This section explains how a normal outbound connection works, followed by two examples explaining how port forwarding and port triggering operate and how they differ.How Your Computer Accesses a Remote Computer through Your RouterWhen a computer on your network needs to access a computer on the Internet, your computer sends your router a message containing source and destination address and process information. Before forwarding your message to the remote computer, your router must modify the source information and must 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 Internet Explorer, beginning a browser session on your computer. Invisible to you, your operating system assigns a service number (port number) to every communication process running on your computer. In this example, let’s say Windows assigns port number 5678 to this browser session. 2. You ask your browser to get a Web page from the Web server at www.example.com. Your computer composes a Web page request message with the following address andport information: • The source address is your computer’s IP address.• The source port number is 5678, the browser session.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-12 Customizing Your Network Settingsv1.0, July 2009• The destination address is the IP address of www.example.com, which your computer finds by asking a DNS server.• The destination port number is 80, the standard port number for a Web 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 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 source address is the IP address of www.example.com.• The source port number is 80, the standard port number for a Web server process.• The destination address is the public IP address of your router.• The destination port number is 33333.The Web server then sends this reply message to your router.5. 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, restoring the original address information replaced by NAT. The message now contains the following address and port information: • The source address is the IP address of www.example.com.• The source port number is 80, the standard port number for a Web server process.• The destination address is your computer’s IP address.• The destination port number is 5678, the browser session that made the initial request.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-13v1.0, July 2009Your router then sends this reply message to your computer, which displays the Web page from www.example.com.6. When you finish your browser session, your router eventually senses 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.How Port Triggering Changes the Communication ProcessIn the preceding example, requests are sent to a remote computer by your router from a particular service port number, and replies from the remote computer to your router are directed to that port number. If the remote server sends a reply back to a different port number, your router will not recognize it and will discard it. However, some application servers (such as FTP and IRC servers) send replies back 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 originatesa 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 must 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, beginning 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. 5. The IRC server sends a return message to your router using the NAT-assigned source port (as in the previous example, let’s say port 33333) as the destination port. The IRC server also sends an “identify” message to your router with destination port 113.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-14 Customizing Your Network Settingsv1.0, July 20096. 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.How Port Forwarding Changes the Communication ProcessIn 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 our 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 Internet Explorer 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: Note: Only one computer at a time can use the triggered application.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-15v1.0, July 2009• The destination address is the IP address of www.example.com, which is the address of your router.• The destination port number is 80, the standard port number for a Web server process.The 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 Network Address Translation (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 user groups or 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 need to 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 must 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.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-16 Customizing Your Network Settingsv1.0, July 2009Configuring 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 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. The DMZ server is configured in the WAN Setup screen, as discussed in “Setting Up a Default DMZ Server” on page 5-8.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.To configure port forwarding to a local server:1. Select Port Forwarding/Port Triggering under Advanced in the main menu. Tip: To ensure that your server computer always has the same IP address, use the reserved IP address feature of your WNDR3700 router. See “Address Reservation” on page 5-4 for instructions on how to use reserved IP addresses.Figure 5-6

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-17v1.0, July 20092. 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 the following section, “Adding a Service.”3. In the corresponding Server IP Address box, 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.Adding a ServiceTo define a service, game, or application that does not appear in the Service Name list, you must first determine which port number or range of numbers is used by the application. You can usually determine this information by contacting the publisher of the application or user groups or newsgroups. When you have the port number information, follow these steps:1. Select Port Forwarding/Port Triggering under Advanced in the main menu.2. Click Add Service. 3. In the Service Name field, enter a descriptive name. 4. In the Service Type field, select the protocol. If you are unsure, select TCP/UDP.5. In the Starting Port field, enter the beginning 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.Figure 5-7

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-18 Customizing Your Network Settingsv1.0, July 20096. In the Server IP Address field, enter the IP address of your local computer that will provide this service.7. Click Apply. The service appears in the list in the Port Forwarding/Port Triggering screen.Editing or Deleting a Port Forwarding EntryTo edit or delete a port forwarding entry:1. In the table, select the 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. 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 “Address Reservation” on page 5-4. 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 “Using a Dynamic DNS Service” on page 5-5. To access your Web server from the Internet, a remote user must know the IP address that has been assigned by your ISP. 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.Configuring 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.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-19v1.0, July 2009When 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.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 Port Forwarding/Port Triggering under Advanced in the main menu. The Forwarding/Port Triggering screen displays.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 6-14.

The port triggering information displays.3. Clear the Disable Port Triggering check box.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.Figure 5-8Note: 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.

Wireless repeating is a type of Wireless Distribution System (WDS).The following figure shows a wireless repeating scenario: To set up a wireless network using WDS, the following conditions must be met for both APs:• Both APs must use the same SSID, wireless channel, and encryption mode (see “Manually Configuring Your Wireless Settings” on page 2-4 or “Using Push 'N' Connect (WPS) to Configure Your Wireless Network” on page 2-12).• Both APs must be on the same LAN IP subnet. That is, all the AP LAN IP addresses are in the same network.• All LAN devices (wired and wireless computers) must be configured to operate in the same LAN network address range as the APs.Warning: If you use the wireless repeating function, your options for wireless security are limited to None or WEP. For more information about wireless security, see Chapter 2, “Safeguarding Your Network.”Figure 5-10Repeater APBase Station AP

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Customizing Your Network Settings 5-23v1.0, July 2009• When the wireless router is in dual band mode (the Mode field on the Wireless Settings screen is set to Up to 270 Mbps at 5 GHz and 54 Mbps at 2.4 GHz), the WDS function works only in 5GHz 11N mode. To use the 2.4GHz 11g protocol with WDS, set the Mode field in the Wireless Settings screen to Up to 130 Mbps at 2.4 GHz. If you make changes in the Wireless Settings screen, click Apply so that they take effect.Wireless Repeating Function You can view or change wireless repeater settings for the wireless router. From the main menu of the browser interface, under Advanced, click Wireless Repeating Function to display the Wireless Repeating Function screen.The wireless router supports two modes of the wireless repeating function, and allows you to control wireless client association:•Wireless Repeater. The wireless router sends all traffic from its local wireless or wired computers to a remote AP. To configure this mode, you must know the MAC address of the remote parent AP. •Wireless Base Station. The wireless router acts as the parent AP, bridging traffic to and from the child repeater AP, as well as handling wireless and wired local computers. To configure this mode, you must know the MAC addresses of the child repeater AP.•Disable Wireless Client Association. Usually this check box is cleared so that the router is an access point for wireless computers. Figure 5-11

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 5-24 Customizing Your Network Settingsv1.0, July 2009If this check box is selected, the router communicates wirelessly only with other APs whose MAC addresses are listed in this screen. The router still communicates with wire-connected LAN devices. Setting Up the Base Station The wireless repeating function works only in hub and spoke mode. The units cannot be daisy chained. You must know the wireless settings for both units. You must know the MAC address of the remote unit. First, set up the base station, and then set up the repeater. To set up the base station:1. Set up both units with exactly the same wireless settings (SSID, mode, channel, and security). Note that the wireless security option must be set to None or WEP.2. Log into the wireless router base unit, under the Advanced heading, select Wireless Repeating Function to display the Wireless Repeating Function screen.3. Select the Enable Wireless Repeating Function check box and the Wireless Base Station radio button.4. Enter the MAC address for the repeater units.5. Click Apply to save your changes.Figure 5-12

If you are using the same model of wireless router for both the base station and repeaters, you must change the LAN IP address for each repeater to a different IP address in the same subnet (see “Using the LAN Setup Options” on page 5-1). 2. Log in to the router that will be the repeater. Check the Wireless Settings screen, and verify that the wireless settings match the base unit exactly. The wireless security option must be set to WEP or None.3. In the Wireless Repeating Function screen, select the Enable Wireless Repeater Mode radio button.This IP address must be in the same subnet as the base station but different from the LAN IP of the base station.4. Fill in the Base Station MAC Address field.5. Click Apply to save your changes.6. Verify connectivity across the LANs. A computer on any wireless or wired LAN segment of the wireless 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 AP.Note: If you are using the WNDR3700 base station with a non-NETGEAR wireless router as the repeater, you might need to change additional configuration settings. In particular, you should disable the DHCP server function on the wireless repeater AP.Note: Failing to change the LAN IP address will cause an IP address conflict in the network because the factory default LAN IP is the same for both units.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Fine-Tuning Your Network 6-1v1.0, July 2009Chapter 6Fine-Tuning Your NetworkThis chapter describes features to help you manage your RangeMax Dual Band Wireless-N Gigabit Router WNDR3700.This chapter includes the following sections:•“Assessing Your Speed Requirements” on page 6-2•“Optimizing Your Network Bandwidth” on page 6-3•“Optimizing Wireless Performance” on page 6-5•“Changing the MTU Size” on page 6-6•“Quality of Service (QoS)” on page 6-7Common connection types and their speed and security considerations are:•Broadband Internet. Your Internet connection speed is determined by your modem type, such as ADSL or cable modem, as well as the connection speed of the sites to which you connect, and general Internet traffic. ADSL and cable modem connections are asymmetrical, meaning they have a lower data rate to the Internet (upstream) than from the Internet (downstream). Keep in mind that when you connect to another site that also has an asymmetrical connection, the data rate between your sites is limited by each side’s upstream data rate. A typical residential ADSL or cable modem connection provides a downstream throughput of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+ and Fiber to the Home (FTTH) will increase the connection speed to tens of Mbps.•Wireless. Your RangeMax Dual Band Wireless-N Gigabit Router WNDR3700 provides a wireless data throughput of up to 300 Mbps using technology called multiple input, multiple output (MIMO), in which multiple antennas transmit multiple streams of data. The use of multiple antennas also provides excellent range and coverage. With the introduction of the newer WPA and WPA2 encryption and authentication protocols, wireless security is extremely strong.To get the best performance, use RangeMax NEXT adapters such as the WN511B for your computers. Although the RangeMax NEXT router is compatible with older 802.11b and 802.11g adapters, the use of these older wireless technologies in your network can result in lower throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for 802.11g). In addition, many older wireless products do not support the latest security protocols, WPA and WPA2.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 6-2 Fine-Tuning Your Networkv1.0, July 2009•Powerline. For connecting rooms or floors that are blocked by obstructions or are distant vertically, consider networking over your building’s AC wiring. NETGEAR’s Powerline HD family of products delivers up to 200 Mbps to any outlet, while the older-generation XE family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for security, and you can configure an individual network password to prevent neighbors from connecting.The Powerline HD family of products can coexist on the same network with older-generation XE family products or HomePlug 1.0 products, but they are not interoperable with these older products.•Wired Ethernet. As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common on newer computers, wired Ethernet remains a good choice for speed, economy, and security. Gigabit Ethernet can extend up to 100 meters with twisted-pair wiring of CAT-5e or better. A wired connection is not susceptible to interference, and eavesdropping would require a physical connection to your network.Assessing Your Speed RequirementsBecause your Internet connection is likely to operate at a much lower speed than your local network, faster local networking technologies might not improve your Internet experience. However, many emerging home applications require high data rates. For example:• Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can disrupt your video, plan to provide at least twice the capacity you need.• Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so a congested network or a noisy link can cause problems.Note: Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, can lower actual data throughput rate.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Fine-Tuning Your Network 6-3v1.0, July 2009• Backing up computers over the network has become popular due to the availability of inexpensive mass storage. Table 6-1 shows the time to transfer 1 gigabyte (GB) of data using various networking technologies.Optimizing Your Network BandwidthAs your network grows, it might consist of several segments of different networking technologies, each providing different throughput. In planning your network, you should first consider which devices will have the heaviest traffic flow between them. Examples are:• A media center in one room streaming high-definition video from a server in another room• A storage device that is used for backing up your computersTable 6-1.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 6-4 Fine-Tuning Your Networkv1.0, July 2009Next, consider the throughput of your network devices. Where possible, make the heaviest-traffic connections using higher-speed technologies, with no lower-speed bottlenecks in the path. Figure 6-1 shows a sample network using multiple networking technologies. In this network, the two PCs with Gigabit (1000 Mbps) Ethernet adapters have a gigabit connection through the GS605 switch to the storage server. This connection should allow for extremely fast backups or quick access to large files on the server. The PC connected through a pair of Powerline HD adapters is limited to the 200 Mbps speed of the Powerline HD connection. Although any of the links in this example would be sufficient for high-traffic applications such as streaming HD video, the use of older devices such as 10 Mbps Ethernet or 802.11b wireless would create a significant bottleneck.Figure 6-1RangeMax Dual Band Wireless-N Gigabit Router

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Fine-Tuning Your Network 6-5v1.0, July 2009Optimizing Wireless PerformanceThe speed and operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless router. You should choose a location for your router that will maximize the network speed.The following list describes how to optimize wireless router performance.•Identify critical wireless links.If your network has several wireless devices, decide which wireless devices need the highest data rate, and locate the router near them. Many wireless products have automatic data-rate fallback, which allows increased distances without loss of connectivity. This also means that devices that are farther away might be slower. Therefore, the most critical links in your network are those where the traffic is high and the distances are great. Optimize those first. •Choose placement carefully.For best results, place your router:– 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).– Avoid obstacles to wireless signals.– Keep wireless devices at least 2 feet from large metal fixtures such as file cabinets, refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.– Keep away from large amounts of water such as fish tanks and water coolers.• Reduce interference.– Avoid windows unless communicating between buildings.– Place wireless devices away from various electromagnetic noise sources, especially those in the 2400–2500 MHz frequency band. Common noise-creating sources are:• Computers and fax machines (no closer than 1 foot)• Copying machines, elevators, and cell phones (no closer than 6 feet)Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range and performance specifications, click the link to the online document “Wireless Networking Basics” in Appendix B.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 6-6 Fine-Tuning Your Networkv1.0, July 2009• Microwave ovens (no closer than 10 feet)• Choose your settings.– Use a scanning utility to determine what other wireless networks are operating nearby, and choose an unused channel.– Turn off SSID broadcast, and change the default SSID. Other nearby devices might automatically try to connect to your network several times a second, which can cause significant performance reduction. • Use WMM to improve the performance of voice and video traffic over the wireless link.Changing 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 any device in the data path has a lower MTU setting than the other devices, the data packets must be split or “fragmented” to accommodate the one with the smallest MTU. The best MTU setting for NETGEAR equipment is often just the default value, and changing the value might fix one problem but cause another. Leave 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 might require an MTU change:– A secure website that won’t open, or displays only part of a Web page– Yahoo e-mail– MSN– 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 such as the inability to access certain Web sites, frames within Web sites, secure login pages, or FTP or POP servers.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Fine-Tuning Your Network 6-7v1.0, July 2009If 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. Table 6-2 describes common MTU sizes and applications. To change the MTU size:1. In the main menu, under Advanced, select WAN Setup. 2. In the MTU Size field, enter a new size between 64 and 1500.3. Click Apply to save the new configuration.Quality of Service (QoS)QoS is an advanced feature that can be used to prioritize some types of traffic ahead of others. The WNDR3700 router can provide QoS prioritization over the wireless link and on the Internet connection. To configure QoS, use the QoS Setup screen. Table 6-2. Common MTU SizesMTU Application1500 The largest Ethernet packet size and the default value. This is the typical setting for non-PPPoE, non-VPN connections, and is the default value for NETGEAR routers, adapters, and switches.1492 Used in PPPoE environments.1472 Maximum size to use for pinging. (Larger packets are fragmented.)1468 Used in some DHCP environments.1460 Usable by AOL if you don't have large e-mail attachments, for example.1436 Used in PPTP environments or with VPN.1400 Maximum size for AOL DSL.576 Typical value to connect to dial-up ISPs.

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 6-8 Fine-Tuning Your Networkv1.0, July 2009From the main menu, under Advanced, select QoS Setup. The QoS Setup screen displays: Using WMM QoS for Wireless Multimedia ApplicationsThe WNDR3700 router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to prioritize wireless voice and video traffic over the wireless link. WMM QoS provides prioritization of wireless data packets from different applications based on four access categories: voice, video, best effort, and background. For an application to receive the benefits of WMM QoS, both it and the client running that application must be WMM enabled. Legacy applications that do not support WMM, and applications that do not require QoS, are assigned to the best effort category, which receives a lower priority than voice and video. WMM QoS is enabled by default. You can disable it in the QoS Setup screen, shown inFigure 6-2 on page 6-8, by clearing the Enable WMM check box and clicking Apply.Figure 6-2

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Fine-Tuning Your Network 6-9v1.0, July 2009Configuring QoS for Internet AccessYou can give prioritized Internet access to the following types of traffic:• For specific applications• For specific online games• On individual Ethernet LAN ports of the router• From a specific device by MAC addressTo specify prioritization of traffic, you must create a policy for the type of traffic and add the policy to the QoS Policy table in the QoS Setup screen.

Click Apply in the QoS Setup screen to save your changes.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.To turn on Universal Plug and Play:1. From the main menu, under Advanced, click UPnP. The UPnP screen displays. 2. The available settings and information in this screen are:•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 might compromise the freshness of the device status but can significantly reduce network traffic.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 enable UPnP.Figure 6-8

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual Fine-Tuning Your Network 6-15v1.0, July 2009•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 should be 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. Click Apply to save your settings.

Do not connect computers, USB modems, printers, CD drives, or DVD drives to the router USB port.Bus Speed/SecUSB 1.1 12 MbitsUSB 2.0 480 Mbits

NETGEAR RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual 7-2 USB Storagev1.0, July 2009Actual bus speeds can vary, depending on the CPU speed, memory, speed of the network, and other variables.The router should work with all USB-compliant external flash and hard drives. For the most up-to-date list of USB drives supported by the router, go to: http://kbserver:netgear.com/kb_web_files/n101300.asp.The router supports FAT, FAT32, NTFS (read only), and Linux file systems.File Sharing ScenariosYou can share files on the USB drive for a wide variety of business and recreational purposes. The files can be any PC, Mac, or Linux file type including text files, Word, PowerPoint, Excel, MP3. pictures, and multimedia. USB drive applications include:• Sharing multimedia with friends and family—sharing MP3 files, pictures, and other multimedia with local and remote users.• Sharing resources on your network—storing files in a central location so that you do not have to power up a computer to perform local sharing. In addition, you can share files between Macintosh, Linux, and PC computers by using the USB drive as a go-between across the systems.• Sharing files with offsite coworkers—sharing files such as Word documents, PowerPoint presentations, and text files with remote users.A few common uses are described in the following sections.Sharing Photos with Friends and FamilyYou can create your own central storage location for photos and multimedia. This eliminates the need to log in to (and pay for) an external photo sharing site.To share files with your friends and family:1. Insert your USB drive into the USB port on the router either directly or with a USB cable.Computers on your local area network (LAN) can automatically access this USB drive using a Web browser or Microsoft Networking.Note: The USB port on the router can be used with one USB hard drive at a time. Do not attempt to use a USB hub attached to the USB port.

If you want to specify read only access, or to allow access from the Internet, see “Configuring USB Storage Advanced Settings” on page 7-7.Storing Files in a Central Location for PrintingThis scenario is for a family that has one high quality color printer directly attached to a PC, but not shared on the local area network (LAN). This family does not have a print server:• The daughter has some photos on her Macintosh computer that she wants to print.• The mother has a photo-capable color printer directly attached to her PC, but not shared on the network.• The mother and daughter’s computers are not visible to each other on the network.How can the daughter print her photos on the color printer attached to her mother’s PC? This is where the USB drive on the router can save you time and effort.1. The daughter accesses the USB drive by typing \\readyshare in the address field of her Web browser. Then she copies the photos to the USB drive.2. The mother uses her Web browser or Microsoft Networking to transfer the files from the USB drive to the PC. Then she prints the files.Sharing Large Files with ColleaguesSending files that are larger than 5 MB can pose a problem for many e-mail systems. The router allows you to share very large files such as PowerPoint presentations or ZIP files with colleagues at another site. Rather than typing up their mail systems with large files, your colleagues can use FTP to easily download shared files from the router.Sharing files with a remote colleague involves the following steps:1. To protect your network, set up appropriate security. Create a user name and password for the colleague with appropriate access.2. If you want to limit USB drive access to only Read Access, from the router USB Storage (Basic Settings) screen, click Edit a Network Folder.
