•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 settings 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 Address. 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.
•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.
– Select Use This MAC Address, and enter it here.
Note: If you enter or change a DNS address, restart the computers on your
network so that these settings take effect.

Chapter 2
Safeguarding Your Network
The N 150 Wireless Router WNR1000 v2h2 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 2-5
•“Changing Wireless Security Settings” on page 2-6
•“Viewing Advanced Wireless Settings” on page 2-11
•“Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13
•“Restricting Wireless Access by MAC Address” on page 2-18
•“Changing the Administrator Password” on page 2-20
•“Backing Up Your Configuration” on page 2-21
•“Understanding Your Firewall” on page 2-22
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 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.
Safeguarding Your Network 2-2
v1.0, August 2010
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, and can cause significant
performance degradation with a slow computer.
To configure the wireless network, you can:
•Manually specify your SSID and your wireless security settings. The WNR1000 v2h2 router
provides two screens for configuring the wireless settings:
–Wireless Settings. You access these under Setup in the main menu (see “Viewing Basic
Wireless Settings” on page 2-6).
–Advanced Wireless Settings. You access these under Advanced in the main menu (see
“Viewing Advanced Wireless Settings” on page 2-11).
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 2-20.

•Use Wi-Fi Protected Setup (WPS) to automatically set the SSID and implement WPA/
WPA2 security on both the router and the client device. If the clients in your network are
WPS capable, you can use Wi-Fi Protected Setup (WPS) to automatically set the SSID and
implement WPA/WPA2 security on both the router and the client device (see “Using Push 'N'
Connect (Wi-Fi Protected Setup)” on page 2-13).
Basic security options are listed in order of increasing effectiveness in Table 2-1. Other features
that affect security are listed in Table 2-2 on page 2-4. For more details on wireless security
methods, click the link to the online document “Wireless Networking Basics” in Appendix B.
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.
WPA2-PSK (AES). Wi-Fi Protected Access version 2
with Pre-Shared Key; WPA2-PSK standard
encryption with the AES encryption type.
WPA-PSK (TKIP) + WPA2-PSK (AES). Mixed mode.
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.
For more information, see “Configuring WPA-PSK
and 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.
Turn 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.
Restrict access based on MAC address. You can restrict access to only trusted computers so
that unknown computers cannot wirelessly connect
to the WNR1000v2 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 2-18.
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 2-22.
Use the Push 'N' Connect feature (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 Push 'N' Connect
(Wi-Fi Protected Setup)” on page 2-13.

Recording Basic Wireless Settings Setup Information
Before and after 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.
•Wireless Network Name (SSID). ______________________________ The SSID identifies
the wireless network. You can use up to 32 alphanumeric characters. The SSID is case-
sensitive. The SSID in the wireless adapter card must match the SSID of the wireless router. In
some configuration utilities (such as in Windows XP), the term “wireless network name” is
used instead of SSID.
•If WEP Authentication is used, circle one: Shared Key or Auto.
–WEP Encryption Key Size. Choose one: 64-bit or 128-bit. Again, the encryption key
size must be the same for the wireless adapters and the wireless router.
–Data Encryption (WEP) Keys. There are two methods for creating WEP data encryption
keys. Whichever method you use, record the key values in the spaces provided.
•Passphrase Method. ______________________________ These characters are
case-sensitive. Enter a word or group of printable characters and click Generate. Not
all wireless devices support the passphrase method.
•Manual Method. These values are not case-sensitive. For 64-bit WEP, enter 10
hexadecimal digits (any combination of 0–9, a–f, or A–F). For 128-bit WEP, enter
26 hexadecimal digits.
Key 1: ___________________________________
Key 2: ___________________________________
Key 3: ___________________________________
Key 4: ___________________________________
• If WPA-PSK or WPA2-PSK authentication is used:
Note: If you select Shared Key, the other devices in the network will not connect
unless they are also set to Shared Key and are configured with the correct key.
Safeguarding Your Network 2-6
v1.0, August 2010
–Passphrase. ______________________________ These characters are case-sensitive.
Enter a word or group of printable characters. When you use WPA-PSK, the other devices
in the network will not connect unless they are also set to WPA-PSK and are configured
with the correct passphrase. Similarly, when you use WPA2-PSK, the other devices in the
network will not connect unless they are also set to WPA2-PSK and are configured with
the correct passphrase.
Use the procedures described in the following sections to specify the WNR1000 v2h2 router. Store
this information in a safe place.
Changing Wireless Security Settings
This section describes the wireless settings that you can view and configure in the Wireless
Settings screen, which you access under Setup in the main menu.
Viewing Basic Wireless Settings
To specify the wireless security settings of your router:
1. Log in to the router as described in “Logging In To Your Wireless Router” on page 1-2.
2. Select Wireless Settings under Setup in the main menu. The Wireless Settings screen
displays.
The available settings in this screen are:
Figure 2-2
Safeguarding Your Network 2-7
v1.0, August 2010
•Name (SSID). The SSID is also known as the wireless network name. Enter a value of up to
32 alphanumeric characters. When more than one wireless network is active, different wireless
network names provide a way to separate the traffic. For a wireless device to participate in a
particular wireless network, it must be configured with the SSID for that network. The
WNR1000 v2h2 default SSID is NETGEAR. You can disable this broadcast as described in
“Viewing Advanced Wireless Settings” on page 2-11.
•Region. This field identifies the region where the WNR1000 v2h2 router can be used. It might
not be legal to operate the wireless features of the wireless router in a region other than one of
those identified in this field.
•Channel. This field determines which operating frequency is used. It should not be necessary
to change the wireless channel unless you notice interference problems with another nearby
wireless network. The wireless router uses channel bonding technology to extend the
bandwidth for data transmission. For more information about the wireless channel
frequencies, see the online document that you can access from “Wireless Networking Basics”
in Appendix B.
•Mode. The default mode is Up to 150Mbps.
The Mode options are:
– Up to 54 Mbps - Legacy Mode with maximum speed of up to 54 Mbps for b/g networks.
– Up to 65 Mbps - Neighbor Friendly Mode - Will not interfere with neighboring wireless
networks.
Note: The region selection feature might not be available in all countries.
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.
Safeguarding Your Network 2-8
v1.0, August 2010
– Up to 150 Mbps - Performance Mode - Maximum Nx speeds up to 150 Mbps. Using
channel expansion to achieve the 150 Mbps data rate, the WNR1000 v2h2 will use the
channel you selected as the primary channel and expand to the secondary channel
(primary channel +4 or –4) to achieve a 40 MHz frame-by-frame bandwidth. The
WNR1000 v2h2 will detect channel usage and will disable frame-by-frame expansion if the
expansion would result in interference with the data transmission of other access points or
clients.
•Security Options. The selection of wireless security options can significantly affect your
network performance. The time it takes to establish a wireless connection can vary depending
on both your security settings and router placement.
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, and can cause
significant performance degradation with a slow computer. Instructions for configuring the
security options can be found in “Choosing Appropriate Wireless Security” on page 2-1. A
full explanation of wireless security standards is available in the online document that you can
access from “Wireless Networking Basics” in Appendix B.
3. Click Apply to save your settings.
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:
•Automatic. With the Automatic option, the router will try both Open System and Shared Key
authentication. Normally this setting is suitable. If it fails, select Open System or Shared Key.
You can also refer to your wireless adapter’s documentation to see what method to use.
•Open System. With Open System authentication and 64 or 128 bit WEP data encryption, the
WNR1000 v2h2 router 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.
Safeguarding Your Network 2-9

2. In the Security Options section, select WEP. The WEP options display.
.
3. Select the authentication type and encryption strength.
4. You can manually or automatically program the four data encryption keys. These values must
be identical on all computers and access points in your network.
•Automatic. In the Passphrase field, enter a word or group of printable characters, and
click Generate. The passphrase is case-sensitive. For example, NETGEAR is not the
same as nETgear. The four key fields are automatically populated with key values.
•Manual. Enter 10 hexadecimal digits (any combination of 0–9, a–f, or A–F). These
entries are not case-sensitive. For example, AA is the same as aa.
Select which of the four keys to activate.
5. Click Apply to save your settings.
Note: If you use a wireless computer to configure WEP settings, you will be disconnected
when you click Apply. You must then either configure your wireless adapter to
match the wireless router WEP settings or access the wireless router from a wired
computer to make any further changes. Not all wireless adapter configuration
utilities support passphrase key generation.

Safeguarding Your Network 2-10
v1.0, August 2010
Configuring WPA-PSK and 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. Also, you might be able
to use the Push 'N' Connect feature to configure this type of security if it is supported by your
wireless clients. See “Using Push 'N' Connect (Wi-Fi Protected Setup)” on page 2-13.
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.
To configure WPA-PSK, WPA2-PSK, or WPA-PSK+WPA2-PSK:
1. Select Wireless Settings under Setup in the main menu. The Wireless Settings screen
displays.
2. Select one of the WPA-PSK or WPA2-PSK options for the security type. The third option
(WPA-PSK [TKIP] + WP2-PSK [AES]) is the most flexible, since it allows clients using
either WPA-PSK or WPA2-PSK.
3. In the Passphrase field, enter a word or group of 8–63 printable characters. The passphrase is
case-sensitive.
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.

for a period of time, you can clear this check box and disable all wireless connectivity.
•Enable SSID Broadcast. Clear this check box to disable broadcast of the SSID, so that
only devices that know the correct SSID can connect. Disabling SSID broadcast nullifies
the wireless network discovery feature of some products such as Windows XP.
•Enable WMM. Clear this check box to disable WMM. WMM (Wireless Multimedia), a
subset of the 802.11e standard, allows wireless traffic to have a range of priorities,
depending on the kind of data. Time-dependent information, like video or audio, will have
a higher priority than normal traffic. For WMM to function correctly, Wireless clients
must also support WMM.

Using Push 'N' Connect (Wi-Fi Protected Setup)
If your wireless clients support Wi-Fi Protected Setup (WPS), you can use this feature to configure
the router’s network name (SSID) and security settings and, at the same time, connect a wireless
client securely and easily to the router. Look for the symbol on your client device. WPS
automatically configures the network name (SSID) and wireless security settings for the router (if
the router is in its default state) and broadcasts these settings to the wireless client.
When you add wireless clients, whether or not they are WPS enabled, the added devices must
share the same network name (SSID) and security passphrase. For more information, see
“Connecting Additional Wireless Client Devices after WPS Setup” on page 2-17.
The WNR1000v2 router provides two methods for connecting to a wireless client that supports
WPS, described in the following sections:
•“Push Button Configuration”
•“Security PIN Entry” on page 2-15
Push Button Configuration
There are two methods to enable a wireless client to join a network using a push button on the
router: using the physical push button or using the software button in the Add WPS Client screen.
Using the Physical Push Button
1. Press the button on the rear of the WNR1000 v2h2 router for over 5 seconds. For information
about the WPS light, see the NETGEAR Wireless Router Setup Manual.
The green light begins to blink in a regular pattern. While the light is blinking, you have 2
minutes to enable WPS on the client that you are trying to connect to the router.
Note: NETGEAR’s Push 'N' Connect feature is based on the Wi-Fi Protected Setup
(WPS) standard (for more information, see http://www.wi-fi.org). All other Wi-Fi-
certified and WPS-capable products should be compatible with NETGEAR
products that implement Push 'N' Connect.
Note: If you choose to use WPS, the only security methods supported are WPA-PSK and
WPA2-PSK. WEP security is not supported by WPS.

These options are available under WPS Settings:
•Router’s PIN. The PIN is displayed so that you can use it to configure the router through
WPS (Wi-Fi Protected Setup). It is also displayed on the router’s label.
•Disable Router’s PIN. If the router’s PIN is disabled, you cannot configure the router’s
wireless settings with WPS. However, if your settings are already configured, you can still
add WPS-enabled wireless clients. The router might disable the PIN if it detects
suspicious attempts to break into your wireless settings; this can happen if the check box is
selected. You can enable the PIN by clearing the check box and clicking Apply.
•Keep Existing Wireless Settings. This check box is automatically selected after WPS is
enabled to prevent unwanted settings changes, and is also selected if you have already
specified wireless security settings or your SSID without using WPS. When this check
box is not selected, adding a new wireless client using the push button or the Add WPS
Client screen (see “Push Button Configuration” on page 2-13) changes the router’s SSID
and security passphrase. You might need to clear it if you are using certain registrars, such
as for a Windows Vista PC, to configure the router through WPS.
Connecting Additional Wireless Client Devices after WPS Setup
You can add WPS-enabled and non-WPS-enabled client devices.
Adding Additional WPS-Enabled Clients
To add an additional wireless client device that is WPS enabled:
1. Follow the procedures in “Push Button Configuration” on page 2-13 or “Security PIN Entry”
on page 2-15.
2. For information about how to view a list of all devices connected to your router (including
wireless and Ethernet-connected), see “Viewing a List of Attached Devices” on page 6-7.
Adding Additional Non-WPS-Enabled Clients
If you are connecting a combination of WPS-enabled clients and clients that are not WPS enabled,
you cannot use the WPS setup procedures to add clients that are not WPS enabled.
Note: Your wireless settings do not change when you add an additional WPS-enabled
client unless you have cleared the Keep Existing Wireless Settings check box (in
the Wireless Settings screen). If you do clear the check box, a new SSID and a
passphrase are generated, and all existing connected wireless clients are
disassociated and disconnected from the router.
Safeguarding Your Network 2-18
v1.0, August 2010
To connect both non-WPS-enabled and WPS-enabled clients to the WNR1000 v2h2 router:
1. Configure the settings of the WNR1000 v2h2 router (shown in the Wireless Settings screen) for
WPA-PSK or WPA2-PSK security, and record that information. See “Configuring WPA-PSK
and WPA2-PSK Wireless Security” on page 2-10.
When you change security settings, all existing connected wireless clients that do not share
those settings are disassociated and disconnected from the router.
2. For the non-WPS-enabled devices that you wish to connect, open the networking utility, and
follow the utility’s instructions to enter security settings.
3. For the WPS-enabled devices that you wish to connect, follow the procedures in “Using Push
'N' Connect (Wi-Fi Protected Setup)” on page 2-13.
The WNR1000 v2h2 router automatically preserves the settings you configured in step 1 so all
clients share the same security settings (for more information, see “Configuring the WPS
Settings” on page 2-16).
4. For information about how to view a list of all devices connected to your router (including
wireless and Ethernet connected), see “Viewing a List of Attached Devices” on page 6-7.
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.
Safeguarding Your Network 2-19
v1.0, August 2010
2. In the Advanced Wireless Settings screen, click Setup Access List to display the Wireless
Card Access List.
3. Click Add to add a wireless device to the wireless access control list. The Wireless Card
Access Setup screen opens and displays a list of currently active wireless cards and their
Ethernet MAC addresses.
4. If the computer you want appears in the Available Wireless Cards list, you can select the radio
button of that computer to capture its MAC address; otherwise, you can manually enter a name
and the MAC address of the authorized computer. You can usually find the MAC address on
the bottom of the wireless device.

7. Select the Turn Access Control On check box.
8. Click Apply to save your Wireless Card Access List settings.
Now, only devices on this list can wirelessly connect to the WNR1000 v2h2 router.
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.
Note: When configuring the router from a wireless computer whose MAC address is
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.
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.
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.
Safeguarding Your Network 2-21
v1.0, August 2010
To change the administrator password:
1. On the main menu, under Maintenance, select Set Password to display the Set Password
screen.
2. To change the password, first enter the old password, then enter the new password twice.
3. Click Apply.
Backing Up Your Configuration
The configuration settings of the WNR1000 v2h2 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.
Figure 2-13
Tip: Before saving your configuration file, change the administrator password to the
default, password. Then change it again after you have 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 N 150 Wireless Router WNR1000 v2h2 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 in order to function. Port triggering can dynamically
allow additional service connections, as described in “Configuring Port Triggering” on
page 5-9. 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.

Restricting Access From Your Network 3-3
v1.0, August 2010
Blocking Access to Internet Services
The WNR1000 v2h2 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.
2. Enable service blocking by selecting either Per Schedule or Always, and then click Apply.
To block by schedule, be sure to specify a time period in the Schedule screen. For information
about scheduling, see “Scheduling Blocking” on page 3-5.

3. Specify a service for blocking by clicking Add. The Block Services Setup screen displays.
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. 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.
5. Select the radio button for the IP address configuration you want to block, and then enter the
IP addresses in the appropriate fields.

•“Using a Dynamic DNS Service” on page 4-5
•“Configuring the WAN Setup Options” on page 4-6
•“Configuring Static Routes” on page 4-8
Using the LAN IP Setup Options
The LAN Setup screen allows configuration of LAN IP services such as Dynamic Host
Configuration Protocol (DHCP) and Routing Information Protocol (RIP).
To configure LAN IP settings, select LAN Setup under Advanced in the main menu. The LAN
Setup screen displays.

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. The default name is WNR1000 v2h2.
Configuring LAN TCP/IP Setup Parameters
These are advanced settings that you might configure if you are a network administrator and your
network contains multiple routers. The router is shipped preconfigured to use private IP addresses
on the LAN side and to act as a DHCP server (see “Using the Router as a DHCP Server” on
page 4-3).
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.
•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 In Only, the router incorporates the RIP information that it receives.
– When set to Both or Out Only, the router broadcasts its routing table periodically.
•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 Disabled.
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.
Customizing Your Network Settings 4-3
v1.0, August 2010
–RIP-1 is universally supported. RIP-1 is usually adequate unless you have an unusual
network setup.
–RIP-2B carries more information than RIP-1 and uses subnet broadcasting.
–RIP-2M carries more information than RIP-1 and uses multicasting.
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.
To specify a pool of IP addresses to be assigned, set 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 specify 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 need to set your computers’ IP addresses manually or they will not be able to access
the router.
Note: 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.

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, enter 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. Enter the MAC address of the computer or server.
4. Click Apply to enter the reserved address into the table.
To edit or delete a reserved address entry:
1. Click the button next to the reserved address you want to edit or delete.
2. Click Edit or Delete.
Figure 4-2
Tip: If the computer is already present on your network, you can copy its MAC
address from the Attached Devices screen and paste it here.
Note: The reserved address is not assigned until the next time the computer contacts
the router’s DHCP server. Reboot the computer or access its IP configuration
and force a DHCP release and renew.
Customizing Your Network Settings 4-5
v1.0, August 2010
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.
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 specify 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.
Select Dynamic DNS under Advanced in the main menu. The Dynamic DNS screen displays.
To configure for a Dynamic DNS service:
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.
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.

2. Select the Use a Dynamic DNS Service check box.
3. Select the name of your Dynamic DNS service provider.
4. Enter the host name (or domain name) that your Dynamic DNS service provider gave you.
5. Enter 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. Enter the password (or key) for your Dynamic DNS account.
7. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can
select the Use Wildcards check box to activate this feature.
For example, the wildcard feature causes *.yourhost.dyndns.org to be aliased to the same IP
address as yourhost.dyndns.org.
8. Click Apply to save your configuration.
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. Select WAN Setup under Advanced in the main menu. The WAN Setup
screen displays.
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
them, but there are other applications that might not function well. In some cases, one local
computer can run the application correctly if that computer’s IP address is entered as the default
DMZ server.
Incoming traffic from the Internet is usually discarded by the router unless the traffic is a response
to one of your local computers or a service that you have configured in the Port Forwarding/Port
Triggering screen. Instead of discarding this traffic, you can have it forwarded to one computer on
your network. This computer is called the default DMZ server.
The WAN Setup screen lets you configure a default DMZ server.
To assign a computer or server to be a default DMZ server:
1. Select the Default DMZ Server check box.
2. In the Default DMZ Server fields, enter the IP address for that computer or server.
3. 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 your 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.
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.

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
size, 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 Size” on page 5-15.
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
Accesses 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.
Customizing Your Network Settings 4-9
v1.0, August 2010
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.
To add or edit a static route:
1. Select Static Routes under Advanced in the main menu. The Static Routes screen displays.

2. Click Add to expand the Static Routes screen.
3. In the Route Name field, enter a name for this static route. (This is for identification purposes
only.)
4. Select the Private check box if you want to limit access to the LAN only. If Private is selected,
the static route is not reported in RIP.
5. Select the Active check box to make this route effective.
6. In the Destination IP Address field, enter the IP address of the final destination.
7. In the IP Subnet Mask field, enter the IP subnet mask for this destination.
If the destination is a single host, enter 255.255.255.255.
8. In the Gateway IP Address field, enter the gateway IP address, which must be a router on the
same LAN segment as the WNR1000 v2h2 router.
9. In the Metric field, enter a number between 1 and 15 as the metric value.
This represents the number of routers between your network and the destination. Usually, a
setting of 2 or 3 works, but if this is a direct connection, set it to 1.
10. Click Apply to have the static route entered into the table.

Fine-Tuning Your Network
This chapter describes how to modify the configuration of the N 150 Wireless Router
WNR1000 v2h2 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:
•“Allowing Inbound Connections to Your Network”
•“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
•“Optimizing Wireless Performance” on page 5-14
•“Changing the MTU Size” on page 5-15
•“Overview of Home and Small Office Networking Technologies” on page 5-16
Allowing Inbound Connections to Your Network
By default, the WNR1000 v2h2 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.
Fine-Tuning Your Network 5-2
v1.0, August 2010
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.
• 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.
Fine-Tuning Your Network 5-3
v1.0, August 2010
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 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,
Fine-Tuning Your Network 5-4
v1.0, August 2010
“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.
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.
Fine-Tuning Your Network 5-5
v1.0, August 2010
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:
• 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 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 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 WNR1000v2 router. See “Using Address
Reservation” on page 4-4 for instructions on how to use reserved IP addresses.

Adding a Custom Service
To define a service, game, or application that does not appear in the Service Name list, you must
first determine which port number or range of numbers is used by the application. You can usually
determine this information by contacting the publisher of the application or user groups or
newsgroups. When you have the port number information, follow these steps:
1. Select Port Forwarding/Port Triggering under Advanced in the main menu.

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 “Using Address Reservation” on page 4-4. 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 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.
Fine-Tuning Your Network 5-10
v1.0, August 2010
While port forwarding creates a static mapping of a port number or range to a single local
computer, port triggering can dynamically open ports to any computer that needs them and can
close the ports when they are no longer needed.
To configure port triggering, you need to know which inbound ports the application needs. Also,
you need to know the number of the outbound port that will trigger the opening of the inbound
ports. You can usually determine this information by contacting the publisher of the application or
user groups or newsgroups.
To set up port triggering:
1. Select Port Forwarding/Port Triggering under Advanced in the main menu. The
Forwarding/Port Triggering screen displays (see Figure 5-1 on page 5-7).
2. Select the Port Triggering radio button. The port triggering information displays.
3. Clear the Disable Port Triggering check box.
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.

Note: If the Disable Port Triggering check box is selected after you configure port
triggering, port triggering is disabled. However, any port triggering

1. Select UPnP under Advanced the main menu. The UPnP screen displays.
2. The available settings and information displayed 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.
