The language is set to English by default. The default language, as well as German, Russian, and Portuguese are always stored in memory. When you select a language other than those automatically stored in flash memory, if you are connected to the Internet at the time you select it, that language is also stored in memory.

• If you are connected to the Internet and select a language that is not already stored in flash memory, the language is downloaded from the NETGEAR server and stored in the current language partition of flash memory.

• If you are not connected to the Internet when you select a language, you can only select as the current language one of the languages that is stored in flash memory.

To specify a language to be used on your router manager screens, do the following:

The language you select is then downloaded and displayed in the language selection box, and your screen display will be in the selected language.

Note: If you are not connected to the Internet and select a language that is not stored

in flash memory, your selection may fail. If you see a “download fails” message after your language selection, make sure you are connected to the Internet and make your selection again.

Using the Setup Wizard

You can manually configure your Internet connection using the Basic Settings screen, or you can allow the Smart Setup Wizard to detect your Internet connection. The Smart Setup Wizard searches your Internet connection for servers and protocols to determine your ISP configuration.

1. From the top of the main menu, select Setup Wizard.

2. Select Yes for the Auto-Detect Connection Type, and then click Next to proceed.

3. Enter your ISP settings, as needed.

4. At the end of the Setup Wizard, click Test to verify your Internet connection. If you have

trouble connecting to the Internet, see Chapter 8, “Troubleshooting.”

Viewing or Manually Configuring Your ISP Settings

To view or configure the basic settings:

1. Log in to the wireless router as described in “Logging In to Your Wireless Router” on

page 1-2.

2. On the Basic Settings screen, select Yes or No depending on whether your ISP requires a login. This selection changes the fields available on the Basic Settings screen.

• Yes. If your ISP requires a login, select the encapsulation method. Enter the login name. If

you want to change the login time-out, enter a new value in minutes.

• No. If your ISP does not require a login, enter the account name, if required, and the

domain name, if required.

Safeguarding Your Network

For 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.

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.

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 2-13

• “Connecting Additional Wireless Client Devices After WPS Setup” on page 2-18

• “Restricting Access to Your Router” on page 2-20

Note: For information about restricting access to USB storage devices, see “Configuring

USB Storage Advanced Settings” on page 7-7.

Planning Your Wireless Network

For 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 WiFi 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.

2-1

v1.3, October 2009

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

– The wireless radio frequency (2.4GHz or 5GHz) 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.

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 WiFi-certified and WPS-capable products should be compatible with NETGEAR products that implement Push 'N' Connect.

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 2-13.

Wireless Placement and Range Guidelines

The 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-ofsight 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.

Safeguarding Your Network 2-2

v1.3, October 2009

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

• Put the router in a vertical position to provide the best side-to-side coverage. Put the router 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 Options

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

Figure 2-1

Wireless data security options

Range: up to 300 foot radius

1) Open system: easy, but no security.

2) WEP: security, but some performance

impact.

3) WPA-PSK: strong security.

4) WPA2-PSK: very strong security.

• 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.

• WPA-PSK (TKIP), WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared key to perform authentication and generate the initial data encryption keys. The very strong authentication along with dynamic per frame re-keying of WPA makes it virtually impossible to compromise.

Using Push 'N' Connect (WPS) to Configure Your Wireless Network

If 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.

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-Ficertified and WPS-capable products should be compatible with NETGEAR products that implement Push 'N' Connect.

Some considerations regarding WPS are:

• WPS supports these types of wireless security: None, WPA-PSK, WPA2-PSK, and WEP (with the authentication type set to Automatic on the Wireless Settings screen). WEP security with shared key authentication 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 2-18.

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” on page 2-14.

• Entering a PIN. For information about using the PIN method, see “Using PIN Entry to Add a

WPS Client” on page 2-15.

SSID will not be changed, and no security will be implemented on the wireless router.

Using PIN Entry to Add a WPS Client

Any wireless computer or wireless adapter that will connect to the wireless router wirelessly is a client. The client must support a WPS PIN, and must have a WPS configuration utility, such as the NETGEAR Smart Wizard or Atheros Jumpstart.

The first time you add a WPS client, make sure that the Keep Existing Wireless Settings check box on the WPS Settings screen is cleared. This is the default setting for the wireless router, and allows it to generate the SSID and WPA/WPA2 security settings when it implements WPS. After WPS is implemented, the wireless router automatically selects this check box so that your SSID and wireless security settings remain the same if other WPS-enabled devices are added later.

Protecting Your Network

This chapter describes how to use the content filtering and reporting features of the RangeMax Dual Band Wireless-N Gigabit Router WNDR3700 to protect your network. You can find these features by selecting the items under Content Filtering in the wireless router main menu.

This chapter includes the following sections:

• “Protecting Access to Your Wireless Router”

• “Restricting Access by MAC Address” on page 3-2

• “Blocking Access to Internet Sites” on page 3-4

• “Blocking Access to Internet Services” on page 3-5

• “Scheduling Blocking” on page 3-8

• “Viewing Logs of Web Access or Attempted Web Access” on page 3-8

• “Configuring E-mail Alert and Web Access Log Notifications” on page 3-9

• “Setting the Time” on page 3-11

Protecting Access to Your Wireless Router

For security reasons, the wireless router has its own user name and password. Also, after a period of inactivity for a set length of time, the administrator login automatically disconnects. When prompted, enter admin for the wireless router user name and password for the wireless router password. You can use procedures in the following sections to change the wireless router password and the amount of time for the administrator’s login time-out.

Note: The user name and password are not the same as a user name or password you

might use to log in to your Internet connection.

NETGEAR recommends that you change this password to a more secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of both upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.

Changing the Built-In Password

1. Log in to the wireless router at its default LAN address of http://www.routerlogin.net with its default user name of admin, default password of password, or using whatever password and LAN address you have chosen for the wireless router.

2. From the main menu, under the Maintenance heading, select Set Password to display the Set Password screen:

3. To change the password, first enter the old password, and then enter the new password twice.

4. Click Apply to save your changes.

Note: After changing the password, you must log in again to continue the

configuration. If you have backed up the wireless router settings previously, you should do a new backup so that the saved settings file includes the new password.

Restricting Access by MAC Address

For increased security, you can restrict access to the wireless network to allow only specific PCs based on their MAC addresses. You can restrict access to only trusted PCs so that unknown PCs cannot wirelessly connect to the WNDR3700 router. MAC address filtering adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed.

To restrict access based on MAC addresses:

Note: If you configure the router from a wireless computer, add your computer’s

MAC address to the access list. Otherwise you will lose your wireless connection when you click Apply. You must then access the wireless router from a wired computer, or from a wireless computer that is on the access control list, to make any further changes.

Blocking Access to Internet Sites

The WNDR3700 router allows you to restrict access based on Web addresses and Web address keywords. Up to 255 entries are supported in the Keyword list.

Keyword application examples:

• If the keyword XXX is specified, the URL www.zzzyyqq.com/xxx.html is blocked.

• If the keyword .com is specified, only websites with other domain suffixes (such as .edu, .org, or .gov) can be viewed.

To block access to Internet sites:

1. Select Block Sites under Content Filtering in the main menu. The Block Sites screen displays.

Figure 3-3

Protecting Your Network 3-4

about scheduling, see “Scheduling Blocking” on page 3-8. Block all access to Internet browsing during a scheduled period by entering a dot (.) as the

keyword, and then set a schedule in the Schedule screen.

3. Add a keyword or domain by entering it in the keyword field and clicking Add Keyword. The keyword or domain name then appears the Block sites containing these keywords or domain names list.

Delete a keyword or domain name by selecting it from the list and clicking Delete Keyword.

4. You can specify one trusted user, which is a computer that is exempt from blocking and logging. Specify a trusted user by entering that computer’s IP address in the Trusted IP Address fields.

Since the trusted user is identified by IP address, you should configure that computer with a fixed IP address.

5. Click Apply to save all your settings in the Block Sites screen.

Blocking Access to Internet Services

The wireless router allows you to block the use of certain Internet services by computers on your network. This is called service blocking or port filtering. Services are functions performed by server computers at the request of client computers. For example, Web servers serve Web pages, time servers serve time and date information, and game hosts serve data about other players’ moves. When a computer on your network sends a request for service to a server computer on the Internet, the requested service is identified by a service or port number. This number appears as the destination port number in the transmitted IP packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web server) request.

You can block the specified service for a single computer, a range of computers (having consecutive IP addresses), or all computers on your network.

6. Click Add to enable your Block Services Setup selections.

Configuring a User-Defined Service

To define a service, first you must determine which port number or range of numbers is used by the application. The service port numbers for many common protocols are defined by the Internet Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application. You can often determine port number information by contacting the publisher of the application, by asking user groups or newsgroups, or by searching.

• Enter the starting port and ending port numbers. If the application uses a single port number, enter that number in both fields.

• If you know that the application uses either TCP or UDP, select the appropriate protocol. If you are not sure, select Both.

Using the LAN Setup Options

The LAN Setup screen allows configuration of LAN IP services such as Dynamic Host Configuration Protocol (DHCP) and Routing Information Protocol (RIP).

The router is shipped preconfigured to use private IP addresses on the LAN side and to act as a DHCP server. The router’s default LAN IP configuration is:

• LAN IP address: 192.168.1.1

• Subnet mask: 255.255.255.0

These addresses are part of the designated private address range for use in private networks and should be suitable for most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in the LAN Setup screen.

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

Using the Router as a DHCP Server

By 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 Reservation

When 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.

2. 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.

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.

4. Click Apply to enter the reserved address into the table.

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.

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 Service

If 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.

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.

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,

Customizing Your Network Settings 5-5

v1.3, October 2009

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

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 hostname.dyndns.org.

From the main menu, under Advanced, select Dynamic DNS to display the Dynamic DNS screen.

Figure 5-2

To configure 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.

Setting Description

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.

Disable SIP ALG Select this feature if you have a SIP (Session Initiation Protocol) telephone or

other SIP base devices, and you want them to communicate with other people. If you have been unable to build a successful SIP connection, selecting this check box allows for such a connection without compromising other SIP ALG (Application-level gateway) firewall settings, such as Disable SPI Firewall. If you are not using SIP devices, leave this check box unchecked.

Setting Up a Default DMZ Server

The 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.

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. Click the Default DMZ Server check box.

2. Type the IP address.

3. Click Apply.

Configuring Static Routes

Static 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.

Allowing Inbound Connections to Your Network

By 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 Router

When 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 and port information:

• The source address is your computer’s IP address.

• The source port number is 5678, the browser session.

Customizing Your Network Settings 5-11

v1.3, October 2009

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

• 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.

Customizing Your Network Settings 5-12

v1.3, October 2009

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

Your 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 Process

In 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 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 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.

Customizing Your Network Settings 5-13

v1.3, October 2009

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

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.

How Port Forwarding Changes the Communication Process

In 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:

Customizing Your Network Settings 5-14

v1.3, October 2009

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

• 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 Triggering

The 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.

Configuring Port Forwarding to Local Servers

Using 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.

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.

To configure port forwarding to a local server:

1. Select Port Forwarding/Port Triggering under Advanced in the main menu.

Application Example: Making a Local Web Server Public

If 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 Triggering

Port 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.

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

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 6-13.

To set up port triggering:

1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The Forwarding/Port Triggering screen displays.

3. Clear the Disable Port Triggering check box.

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. 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.

Wireless Repeating (Also Called WDS)

The WNDR3700 router can be used with a wireless access point (AP) to build large bridged wireless networks. Wireless repeating is a type of Wireless Distribution System (WDS).

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.”

The following figure shows a wireless repeating scenario:

Repeater APBase Station AP

Figure 5-10

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 2-13).

• 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.

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.

Figure 5-11

For each wireless radio (2.4GHz and 5GHz), 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.

If 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.

Note: The WNDR3700 router is always in dual band concurrent mode, unless you turn

off one radio. Be aware that if you enable the wireless repeater in either radio band, the wireless base station or wireless repeater cannot be enabled in the other radio band. However, if you enable the wireless base station in either radio band and use the other radio band as a wireless router or wireless base station, dual band concurrent mode is not affected.

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.

Setting Up a Repeater Unit

Use a wired Ethernet connection to set up the repeater unit to avoid conflicts with the wireless connection to the base station.

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.

To configure a WNDR3700 router as a repeater unit:

1. 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.

2. In the Wireless Repeating Function screen (depending on the frequency you want to use), select the Enable Wireless Repeating Function check box and the Wireless Repeater radio button.

3. Fill in the Repeater IP Address field. This IP address must be in the same subnet as the base station, but different from the LAN IP of the base station

4. Click Apply to save your changes.

5. 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.

Chapter 6

Fine-Tuning Your Network

This 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 6-7

Common 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 adapters, such as the WNDA3100, for your computers. Although the RangeMax 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.

RangeMax™ Dual Band Wireless-N Gigabit Router WNDR3700 User Manual

• 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.

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.

Assessing Your Speed Requirements

Because 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.
