Configuring Y our Internet Connection Using the Smart Setup Wizard

You can manually configure your Internet connection using the Basic Settings screen, or you can allow the Smart Setup Wizard to determine your Internet Service Provider (ISP) configuration.
The Smart Setup Wizard searches your Internet connection for servers and protocols to determine your ISP configuration. This feature is not the same as the Smart Wizard configuration assistant that appears only when the router is in its factory default state. To use the Smart Setup Wizard to assist with configuration or to verify the Internet connection settings, follow this procedure:
1. From the top of the main menu of the browser interface, click Setup Wizard.
2. Click Next to proceed. Enter your ISP settings, as needed.
3. At the end of the Setup Wizard, click Test to verify your Internet connectio n. If yo u have
trouble connecting to the Internet, see Chapter 7, “Troubleshooting.”

Viewing and Configuring Basic ISP Settings

Settings related to your Internet service are specified in the Basic Settings screen. To access the Basic Settings screen, from the main menu of the router’s Web Configuration Interface, under Setup, select Basic Settings.
The content you see in the Basic Settings screen depends on whether your ISP requires that you log in with a user name and password for Internet access.
• No login required by ISP. If no login is required by your ISP, the following settings appear in the Basic Settings screen.

– Account Name (might also be called Host Name). The account name is provided to the
ISP during a DHCP request from your router. In most cases, this setting is not required, but some ISPs require it for access to ISP services such as mail or news servers.
– Domain Name. The domain name is provided by your router to computers on your LAN
when the computers request DHCP settings from your router. In most cases, this setting is not required.
– Internet IP Address. Determines how your router obtains an IP address for Internet
access.
• If your ISP assigns an IP address dynamically (by DHCP), select Get Dynamically From ISP.

• If your ISP has assigned you a permanent, fixed (static) IP address for your computer, select Use Static IP Addr ess. Enter the IP address that your ISP assigned. Also, enter the subnet mask and the gateway IP address. The gateway is the ISP’ s router to which your router will connect.
– Domain Name Server (DNS) Address. If you know that your ISP does not automatically
transmit DNS addresses to the router during login, select Use These DNS Servers, and enter the IP address of your ISP’s primary DNS server. If a secondary DNS server address is available, enter it also.
Note: If you enter or change a DNS address, restart the computers on your
network so that these settings take effect.
– Router MAC Address. This section determines the Ethernet MAC address that the router
will use on the Internet port. Typically, you would leave Use Default Address selected. However, some ISPs (especially cable modem providers) register the Ethernet MAC address of the network interface card in your computer when your account is first opened. They then accept only traffic from the MAC address of that computer. This feature allows your router to masquerade as that computer by “cloning” or “spoofing” its MAC address.
To change the MAC address, select one of the following methods:
• Select Use Computer MAC Address. The router will then capture and use the MAC address of the computer that you are now using. You must be using the one computer that is allowed by the ISP.

Safeguarding Your Network
The RangeMax Dual Band Wireless-N Router WNDR3300 provides highly effective security features, which are covered in detail in this chapter.
This chapter includes the following sections:
• “Choosing Appropriate Wireless Security”
• “Recording Basic Wireless Settings Setup Information” on page 2-4
• “Changing Basic Wireless Settings” on page 2-5
• “Viewing Advanced Wireless Settings” on page 2-11
• “Using WPS Security (Wi-Fi Protected Setup)” on page 2-12

• “Changing the Administrator Password” on page 2-19
• “Backing Up Your Configuration” on page 2-20
• “Understanding Your Firewall” on page 2-21

Choosing Appropriate Wireless Security

Unlike wired networks, wireless networks allow anyone with a compatible adapter to receive your wireless data transmissions well beyond your walls. Operating an unsecured wireless network creates an opportunity for outsiders to eavesdrop on your network traffic or to enter your network to access your computers and files. Indoors, computers can connect over 802.11g/n wireless networks at ranges of up to 300 feet. Such distances can allow for others outside your immediate area to access your network. Use the security features of your wireless equipment that are appropriate to your needs.
The time it takes to establish a wireless connection can vary depending on both your security settings and router placement.
Stronger security methods can entail a cost in terms of throughput, latency, battery consumption, and equipment compatibility. In choosing an appropriate security level, you can also consider the effort compared to the reward for a hacker to break into your network. As a minimum, however,

NETGEAR recommends using WEP with Shared Key authentication. Do not run an unsecured wireless network unless it is your intention to provide free Internet access for the public.
WEP connections can take slightly longer to establish. Also, WEP, WPA-PSK, and WPA2-PSK encryption can consume more battery power on a notebook computer, an d can cause significan t performance degradation with a slow computer.
Note: NETGEAR recommends that you change the administration password of your
router. Default passwords are well known, and an intruder can use your administrator access to read or disable your security settings. For information about how to change the administrator password, see “Changing the Administrator
Password” on page 2-19.

Table 2-1. Wireless Security Options
Security Type Description None. No wireless security. Recommended only for
troubleshooting wireless connectivity. Do not run an unsecured wireless network unless it is your intention to provide free Internet access for the public.
WEP. Wired Equivalent Privacy. Wired Equivalent Privacy (WEP) data encryption
provides moderate data security. WEP Shared Key authentication and WEP data encryption can be defeated by a determined eavesdropper using publicly available tools. For more information, see “Configuring WEP
Wireless Security” on page 2-8.
WPA-PSK (TKIP). WPA-PSK standard encryption with TKIP encryption type.

Wi-Fi Protected Access with Pre-Shared Key (WPA­PSK and WPA2-PSK) data encryption provides extremely strong data security, very effectively blocking eavesdropping. Because WPA and WPA2 are relatively new standards, older wireless adapters and devices might not support them. For more information, see “Configuring WPA-PSK,
WPA2-PSK, or WPA-PSK+WPA2-PSK Wireless Security” on page 2-10.
Table 2-2. Other Features That Enhance Security
Security Type Description Disable the wireless router radio. If you disable the wireless router radio, wireless
devices cannot communicate with the router at all. You might disable this when you are away or when other users of your network all use wired connections. For more information, see “Viewing Advanced
Wireless Settings” on page 2-11.
T urn off the broadcast of the wireless network name SSID.
If you disable the broadcast of the SSID, only devices that know the correct SSID can connect. This nullifies the wireless network discovery feature of some products such as Windows XP, but your data is still fully exposed to an intruder using available wireless eavesdropping tools. For more information, see “Viewing Advanced
Wireless Settings” on page 2-11.

Table 2-2. Other Features That Enhance Security (continued)
Security Type Description Restrict access based on MAC address. You can restrict access to only trusted computers so
that unknown computers cannot wirelessly connect to the WNDR3300 router. MAC address filtering adds an obstacle against unwanted access to your network by the general public, but the data broadcast over the wireless link is fully exposed. This data includes your trusted MAC addresses, which can be read and impersonated by a hacker. For more information, see “Restricting Wireless
Access by MAC Address” on page 2-17.
Modify your firewall’s rules. By default, the firewall allows any outbound traffic
and prohibits any inbound traffic except for responses to your outbound traffic. However, you can modify the firewall’s rules. For more information, see “Understanding Your
Firewall” on page 2-21.
Use WPS (Wi-Fi Protected Setup). Wi-Fi Protected Setup provides easy setup by
means of a push button. Older wireless adapters and devices might not support this. Check whether devices are WPS enabled. For more information, see “Using WPS Security (Wi-
Fi Protected Setup)” on page 2-12.

Recording Basic Wireless Settings Setup Information

Before customizing your wireless settings, print this section, and record the following information. If you are working with an existing wireless network, the person who set up or is responsible for the network can provide this information. Otherwise, you must choose the settings for your wireless network. Either way , record the settings for your wireless network in the spaces provided.

not be legal to operate the wireless features of the wireless router in a region other than one of those identified in this field.
Note: The region selection feature might not be available in all countries.
• Mode. This field determines which 802.11 data communications protocol is used. You can
select one of the following modes: – Up to 270 Mbps at 2.4 GHz – Up to 270 Mbps at 5 GHz and 54 Mbps at 2.4 GHz. This is the default mode. – Up to 130 Mbps at 2.4 GHz – Up to 130 Mbps at 5 GHz and 54 Mbps at 2.4 GHz The following information might help you to decide which mode to select: – Up To 54 Mbps. Legacy mode, for compatibility with the slower 802.11b and
802.11g wireless devices.
– Up To 130 Mbp s. Neighbor Friendly mode, for reduced interference with neighboring
wireless networks. Provides two transmission streams with different data on the same
channel at the same time, but also allows 802.11b and 802.11g wireless devices. – Up To 270 Mbps. Performance mode, using channel expansion to achieve the 270
Mbps data rate. The WNDR3300 router uses the channel you selected as the primary
channel and expands to the secondary channel (primary channel +4 or –4) to achieve a
40 MHz frame-by-frame bandwidth. The WNDR3300 router detects channel usage
and disables frame-by-frame expansion if the expansion would result in interference
with the data transmission of other access points or clients.
Note: The maximum wireless signal rate is derived from the IEEE Standard 802.11
specifications. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate.

Configuring WEP Wireless Security

WEP Shared Key authentication and WEP data encryption can be defeated by a determined eavesdropper using publicly available tools.
WEP offers the following options:
• Open System. With Open System authentication and 64 or 128 bit WEP data encryption, the
WNDR3300 does perform data encryption but does not perform any authentication. Anyone can join the network. This setting provides very little practical wireless security.
• Shared Key. With Shared Key authentication, a wireless device must know the WEP key to
join the network. Select the encryption strength (64 or 128 bit data encryption). Manually enter the key values, or enter a word or group of printable characters in the Passphrase field. Manually entered keys are not case-sensitive, but passphrase characters are case-sensitive.
• Automatic. The wireless router automatically detects whether Open System or Shared Key is
used.

5. Click Apply to save your settings.

Configuring WPA-PSK, WPA2-PSK, or WPA-PSK+WPA2-PSK Wireless Security

Wi-Fi Protected Access with Pre-Shared Key (WPA-PSK and WPA2-PSK) data encryption provides extremely strong data security, very effectively blocking eavesdropping. Because WPA and WPA2 are relatively new standards, older wireless adapters and devices might not support them. Check whether newer drivers are available from the manufacturer.
WPA–Pre-Shared Key does perform authentication. WPA-PSK uses TKIP (Temporal Key Integrity Protocol) data encryption, and WPA2-PSK uses AES (Advanced Encryption Standard) data encryption. Both methods dynamically change the encryption keys making them nearly impossible to circumvent.
Mixed mode allows clients using either WPA-PSK (TKIP) or WPA2-PSK (AES). This provides the most reliable security, and is easiest to implement, but it might not be compatible with older adapters.
Note: Not all wireless adapters support WPA. Furthermore, client software is also
required. Windows XP with Service Pack 2 does include WPA support. Nevertheless, the wireless adapter hardware and driver must also support WPA. For instructions on configuring wireless computers or PDAs (personal digital assistants) for WPA-PSK security, consult the documentation for the product you are using.
To configure WPA-PSK, WPA2-PSK or WPA-PSK+WPA2-PSK:
1. Select Wireless Settings under Setup in the main menu.

encryption. The WNDR3300 router and any connected clients share the same network names (SSIDs), for both 11N and 1 1G. Note that WPS is not a new security feature—it makes existing security features easier to configure.
Note: Using WPS security might disconnect devices you already have connected to your
router. When you add wireless clients, whether or not they are WPS enabled, the added devices must share the same network names (SSIDs) and security passphrase. For more information, see “Connecting Additional Wireless Client
Devices after WPS Setup” on page 2-15.

Restricting Wireless Access by MAC Address

When a Wireless Card Access List is configured and enabled, the router checks the MAC address of any wireless device attempting a connection and allows only connections to computers identified on the trusted computers list.
The Wireless Card Access List displays a list of wireless computers that you allow to connect to the router based on their MAC addresses. These wireless computers must also have the correct SSID and wireless security settings to access the wireless router.
The MAC address is a network device’s unique 12-character physical address, containing the hexadecimal characters 0–9, a–f, or A–F only, and separated by colons (for example, 00:09:AB:CD:EF:01). It can usually be found on the bottom of the wireless card or network interface device. If you do not have access to the physical label, you can display the MAC address using the network configuration utilities of the computer. In WindowsXP, for example, typing the ipconfig/all command in an MSDOS command prompt window displays the MAC address as Physical Address. You might also find the MAC addresses in the router’s Attached Devices screen.
To restrict access based on MAC addresses:
1. Select Wireless Settings under Advanced in the main menu.
2. In the Wireless Settings screen, click Setup Access List to display the Wireless Card Access
List.

not in the Trusted PC list, if you select Turn Access Control On, you 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.
8. Click Apply to save your Wireless Card Access List settings. Now, only devices on this list are allowed to wirelessly connect to the WNDR3300 router.
Warning: MAC address filtering adds an obstacle against unwanted access to your
network by the general public. However, because your trusted MAC addresses appear in your wireless transmissions, an intruder can read them and impersonate them. Do not rely on MAC address filtering alone to secure your network.

Changing the Administrator Password

The default password for the router’s Web Configuration Manager is password. NETGEAR recommends that you change this password to a more secure password.
Tip: Before changing the router password, back up your configuration settings with the
default password of password. If you save the settings with a new password, and then you later forget the new password, you will have to reset the router back to the factory defaults, and log in using the default password of password. This means you will have to re-enter all the router configuration settings. For information about how to back up your settings, see “Backing Up and Restoring the Configuration” on
page 6-8.

Backing Up Your Configuration

The configuration settings of the WNDR3300 router are stored within the router in a configuration file. You can back up (save) this file and retrieve it later. NETGEAR recommends that you save your configuration file after you complete the configuration. If the router fails or becomes corrupted, or an administrator password is lost, you can easily re-create your configuration by restoring the configuration file.
For instructions on saving and restoring your configuration file, see “Managing the Configuration
File” on page 6-7.
Tip: Before saving your configuration file, change the administrator password to the
default, password. Then change it again after you ha ve saved the configuration file. If you save the file with a new password, and then you later forget the new password, you will have to reset the router back to the factory defaults and log in using the default password of password. This means you will have to re-enter all the router configuration settings.

Understanding Your Firewall

Your RangeMax Dual Band Wireless-N Router WNDR3300 contains a true firewall to protect your network from attacks and intrusions. A firewall is a device that protects one network from another while allowing communication between the two. Using a process called Stateful Packet Inspection, the firewall analyzes all inbound and outbound traffic to determine whether or not it will be allowed to pass through.
By default, the firewall allows any outbound traffic and prohibits any inbound traffic except for responses to your outbound traffic. However, you can modify the firewall’s rules to achieve the following behavior:
• Blocking sites. Block access from your network to certain Web locations based on Web addresses and Web address keywords. This feature is described in “Blocking Access to
Internet Sites” on page 3-1.
• Blocking services. Block the use of certain Internet services by specific computers on your network. This feature is described in “Blocking Access to Internet Services” on page 3-3.
• Scheduled blocking. Block sites and services according to a daily schedule. This feature is described in “Scheduling Blocking” on page 3-5.
• Allow inbound access to your server. To allow inbound access to resources on your local network (for example, a Web server or remote desktop program), you can open the needed services by configuring port forwarding as described in “Allowing Inbound Connections To
Your Network” on page 5-1.
• Allow certain games and applications to function correctly. Some games and applications need to allow additional inbound traffic to function. Port triggering can dynamically allow additional service connections, as described in “Allowing Inbound Connections To Your
Network” on page 5-1. Another feature to solve application conflicts with the firewall is
Universal Plug and Play (UPnP), described in “Using Universal Plug and Play” on page 5-12.

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

Blocking Access to Internet Services

The WNDR3300 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.
To block access to Internet services:
1. Select Block Services under Content Filtering in the main menu. The Block Services screen displays.
Figure 3-2

4. From the Service Type list, select the application or service to be allowed or blocked. The list already displays several common services, but you are not limited to these choices. To add any additional services or applications that do not already appear, select User Defined.
5. Select the radio button for the IP address configuration you want to block, and then enter the IP addresses in the appropriate fields.
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.

Configuring a Device Name

The device name is a user-friendly name for the router. This name is shown in the Network on Windows Vista and the Network Explorer on all Windows systems. The Device Name field cannot be blank.

Configuring LAN TCP/IP Setup Parameters

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 this screen.
The LAN IP settings are:
• IP Address. The LAN IP address of the router.
4-2 Customizing Your Network Settings
v1.0, February 2008
NETGEAR RangeMax™ Dual Band Wireless-N Router WNDR3300 Reference Manual
• IP Subnet Mask. The LAN subnet mask of the router. Combined with the IP address, the IP subnet mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router .
• RIP Direction. RIP allows a router to exchange routing information with other routers. The RIP Direction selection controls how the router sends and receives RIP packets. Both is the default.
– When set to Both or Out Only, the router broadcasts its routing table periodically. – When set to Both or In Only, the router incorporates the RIP information that it receives. – When set to None, the router does not send any RIP packets and ignores any RIP packets
received.
• RIP Version. This controls the format and the broadcasting method of the RIP packets sent by the router. (It recognizes both formats when receiving.) The default setting is RIP-1.
– RIP-1 is universally supporte d. RIP-1 is usually adequate unless you have an unusual
network setup.
– RIP-2 carries more information. RIP-2B uses subnet broadcasting.
Note: If you change the LAN IP address of the router while connected through the
browser, you will be disconnected. You must then open a new connection to the new IP address and log in again.

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.
Customizing Your Network Settings 4-3
v1.0, February 2008
NETGEAR RangeMax™ Dual Band Wireless-N Router WNDR3300 Reference Manual
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.

Using 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.

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 addre ss, 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, 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.

Configuring the WAN Setup Options

The WAN Setup options let you configure a DMZ (demilitarized zone) server, change the Maximum Transmit Unit (MTU) size, and enable the wireless router to respond to a ping on the WAN (Internet) port. From the main menu of the browser interface, under Advanced, click WAN Setup to view the WAN Setup screen.

Disabling the 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.

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
Customizing Your Network Settings 4-7
v1.0, February 2008
NETGEAR RangeMax™ Dual Band Wireless-N Router WNDR3300 Reference Manual
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 s erver. 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.

Responding to a Ping on the Internet (WAN) Port

If you want the router to respond to a ping from the Internet, select the Respond to Ping on Internet Port check box. This should be used only as a diagnostic tool, since it allows yo ur router
to be discovered by Internet scanners. Do not select this check box unless you have a specific reason to do so, such as when troubleshooting your connection.

Setting the MTU Size

The normal MTU value for most Ethernet networks is 1500 bytes, 1492 bytes for PPPoE connections, or 1450 for PPTP connections. For some ISPs, you might need to reduce the MTU, but this is rarely required and should not be done unless you are sure it is necessary for your ISP connection. For more information, see “Changing the MTU” on page 5-20.
To change the MTU size:
1. In the MTU Size field, enter a new size between 64 and 1500.
2. Click Apply to save the new configuration.

Configuring 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. For more information about NAT, see “How Your Computer
Communicates with a Remote Computer through Your Router” on page 5-2.
To change the NAT option:
1. In the NAT Filtering area, select either the Secured or the Open radio button.
2. Click Apply to save the new configuration.

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.

Fine-Tuning Your Network
This chapter describes how to modify the configuration of the RangeMax Dual Band Wireless-N Router WNDR3300 to allow specific applications to access the Internet or to be accessed from the Internet, and how to make adjustments to enhance your network’s performance.
This chapter includes the following sections:

• “Configuring Port Forwarding to Local Servers” on page 5-6
• “Configuring Port Triggering” on page 5-9
• “Using Universal Plug and Play” on page 5-12

• “Changing the MTU” on page 5-20
• “Optimizing Your Network Bandwidth” on page 5-21
• “Overview of Home and Small Office Networking Technologies” on page 5-23

Allowing Inbound Connections To Your Network

By default, the WNDR3300 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 wo rks, followed by two examples explaining how port forwarding and port triggering operate and how they differ.

How Your Computer Communicates with 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.
• 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.
5-2 Fine-Tuning Your Network
v1.0, February 2008
NETGEAR RangeMax™ Dual Band Wireless-N Router WNDR3300 Reference Manual
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. 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 does not recognize it and discards 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,
Fine-Tuning Your Network 5-3
v1.0, February 2008
NETGEAR RangeMax™ Dual Band Wireless-N Router WNDR3300 Reference Manual
“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 that 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.
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 numb er 33333. F inding an act ive 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 determing 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. Usually, 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 W eb server running on a computer in your local network. Using port forwardi ng, 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 that 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:
• 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 can usually 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 4-7.
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 that 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 WNDR3300 router. See “Using Address
Reservation” on page 4-4 for instructions on how to use reserved IP addresses.

v1.0, February 2008
NETGEAR RangeMax™ Dual Band Wireless-N Router WNDR3300 Reference Manual
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 “Using Address Reservation” on page 4-4. In this example, your router always gives your Web server an IP address of 192.168.1.33.
2. Configure the Port Forwarding screen 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 4-5. 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.
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 po rts 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 “Using Universal Plug and Play” on page 5-12.

Using Universal Plug and Play

Universal 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.
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.
To turn on Universal Plug and Play:
1. From the main menu of the browser interface, 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.
• 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.

Optimizing Wireless Performance

The speed and operating distance or range of your wireless connection can vary significan tly based on the physical placement of the wireless router. You should choose a location for your router that will maximize the network speed.
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.
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.
Fine-Tuning Your Network 5-13
v1.0, February 2008
NETGEAR RangeMax™ Dual Band Wireless-N Router WNDR3300 Reference Manual
• 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 wireless devices 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) – 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.

Configuring Quality of Service

Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of traffic ahead of others. The WNDR3300 router can provide QoS prioritization over the wireless link and on the Internet connection. To configure QoS, use the QoS Setup screen.

Using WMM QoS for Wireless Multimedia Applications

The WNDR3300 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 su pport WMM, and applications that do not require QoS, are assigned to the best effort category, which receives a lower priority than voice and video.

You 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 address To specify prioritization of traffic, you must create a policy for the type of traffic and add the

Changing the MTU

The 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 Web site 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.

If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are willing to experiment, you can gradually reduce the MTU from the maximum value of 1500 until the problem goes away. Table 5-1 describes common MTU sizes and applications.
Table 5-1. Common MTU Sizes
MTU Application
1500 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.
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.

Optimizing Your Network Bandwidth

As 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 computers

Next, 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 5-11
Figure 5-11 shows a sample network using multiple networking technologies. In this network, the
two PCs with Gigabit (1000 Mbps) Ethernet adapters have a gigabit conn ection 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.

Overview of Home and Small Office Networking Technologies

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 Router WNDR3300 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.
• 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.
• Backing up computers over the network has become popular due to the availability of inexpensive mass storage. Table 5-2 shows the time to transfer 1 gigabyte (GB) of data using various networking technologies.
Table 5-2. Theoretical Transfer Time for 1 Gigabyte
Network Connection Theoretical Raw Transfer Time
Gigabit wired Ethernet 8 seconds RangeMax NEXT Wireless-N 26 seconds Powerline HD 40 seconds 100 Mbps wired Ethernet 80 seconds
802.11n wireless 45 seconds
802.11g wireless 150 seconds
802.11b wireless 700 seconds 10 Mbps wired Ethernet 800 seconds Cable modem (3 Mbps) 2700 seconds Analog modem (56 kbps) 144,000 seconds (40 hours)
