Position Your Modem Router
The modem router lets you access your network from virtually anywhere within the operating
range of your wireless network. However, the operating distance or range of your wireless
connection can vary significantly depending on the physical placement of your modem router.
For example, the thickness and number of walls the wireless signal passes through can limit
the range. For best results, place your modem router:
• Near the center of the area where your computers and other devices operate, and
preferably within line of sight to your wireless devices.
• So it is accessible to an AC power outlet and near Ethernet cables for wired computers.
• In an elevated location such as a high shelf, keeping the number of walls and ceilings
between the modem router and your other devices to a minimum.
• Away from electrical devices that are potential sources of interference, such as ceiling
fans, home security systems, microwaves, PCs, or the base of a cordless phone or 2.4
GHz cordless phone.
• Away from any large metal surfaces, such as a solid metal door or aluminum studs. Large
expanses of other materials such as glass, insulated walls, fish tanks, mirrors, brick, and
concrete can also affect your wireless signal.
• With the antennas in a vertical position to provide the best side-to-side coverage or in a
horizontal position to provide the best up-and-down coverage, as applicable.
When you use multiple access points, it is better if adjacent access points use different radio
frequency channels to reduce interference. The recommended channel spacing between
adjacent access points is 5 channels (for example, use Channels 1 and 6, or 6 and 11).
ADSL Microfilters
If this is the first time you have cabled a router between a DSL phone line and your computer
or laptop, you might not be familiar with ADSL microfilters. If you are, you can skip this
section and proceed to Cable Your Modem Router on page 14.
An ADSL microfilter is a small in-line device that filters DSL interference out of standard
phone equipment that shares the same line with your DSL service. Every telephone device
that connects to a telephone line that provides DSL service needs an ADSL microfilter to filter
out the DSL interference. Example devices are telephones, fax machines, answering
machines, and caller ID displays. Note that not every phone line in your home necessarily
carries DSL service. That depends on the DSL service setup in your home.
Note: Often the ADSL microfilter is in the box with the modem router. If
you purchased the modem router in a country where a microfilter is
not included, you have to acquire the ADSL microfilter separately.
Hardware Setup

One-Line ADSL Microfilter
Plug the ADSL microfilter into the wall outlet and plug your phone equipment into the jack
labeled Phone. The modem router plugs directly into a separate DSL line. Plugging the
modem router into the phone jack blocks the Internet connection. If you do not have a
separate DSL line for the modem router, the best thing to do is to use an ADSL microfilter
with a built-in splitter (see Two-Line ADSL Microfilter )
Plugs into DSL line
.
Figure 4. One-line ADSL microfilter
If you do not have a separate DSL line for the modem router, the second-best solution is to
get a separate splitter. To use a one-line filter with a separate splitter, insert the splitter into
the phone outlet, connect the one-line filter to the splitter, and connect the phone to the filter.
Two-Line ADSL Microfilter
Use an ADSL microfilter with a built-in splitter when there is a single wall outlet that provides
connectivity for both the modem router and your telephone equipment. Plug the ADSL
microfilter into the wall outlet, plug your phone equipment into the jack labeled Phone, and
plug the modem router into the jack labeled ADSL.
Plugs into the DSL line
Figure 5. Two-line ADSL microfilter with built-in splitter
Summary
• One-line ADSL microfilter. Use with a phone or fax machine.
• Splitter. Use with a one-line ADSL microfilter to share an outlet with a phone and the
modem router.
• Two-line ADSL microfilter with built-in splitter. Use to share an outlet with a phone and the
modem router.

Modem Router Setup Preparation
You can set up your modem router with the NETGEAR Genie as described in NETGEAR
Genie Setup on page 19, with the Setup Wizard as described in Setup Wizard on page 22, or
manually as described in Manual Setup (Basic Settings) on page 23. However, before you
start the setup process, you need to have your ISP information and to make sure the laptops,
PCs, and other devices in the network have the settings described here.
Note: For a Macintosh or Linux system, you have to use manual setup.
Use Standard TCP/IP Properties for DHCP
If you set up your computer to use a static IP address, you have to change the settings back
so that it uses Dynamic Host Configuration Protocol (DHCP).
Replace an Existing Modem and Router
To replace an existing modem and router, disconnect them and set them aside before starting
the modem router setup.
Gather ISP Information
You need the following information to set up your modem router and to check that your
Internet configuration is correct. Your Internet service provider (ISP) should have provided
you with all the information needed to connect to the Internet. If you cannot locate this
information, ask your ISP to provide it. When your modem router Internet connection is set
up, you no longer need to launch the ISP’s login program on your computer to access the
Internet. When you start an Internet application, your modem router automatically logs you in.
• Active Internet service provided by a DSL account
• The ISP configuration information for your DSL account
-ISP login name and password
-ISP Domain Name Server (DNS) addresses
-Fixed or static IP address
-Host and domain names
-Depending on how your ISP set up your Internet account, you could need to know
one or more of these settings for a manual setup:
- Virtual path identifier (VPI) and virtual channel identifier (VCI) parameters
- Multiplexing method
- Host and domain names

NETGEAR Genie Setup
NETGEAR Genie is on the Resource CD and runs on a PC with Microsoft Windows 7,
Windows Vista, Windows XP, or Windows 2000 with Service Pack 2 or later. It is the easiest
way to set up the modem router because it automates many steps and verifies that those
steps have been successfully completed. It takes about 15 minutes to complete.
Before running NETGEAR Genie on a corporate PC, check with your company’s network
support staff. Corporate network settings or virtual private network (VPN) client software
might conflict with your modem router settings. To avoid a conflict, use another PC.
1. Locate the DSL settings information (user name and password) provided by your ISP.
Contact your ISP if you do not have it.
2. Insert the Resource CD into your Windows PC. The CD starts and detects the language you
are using on your PC. Select a different language option, if you prefer.
If the CD does not start, go to the CD drive (under My Computer on Windows), browse
the CD, and double-click .
3. When the Welcome screen displays, click Setup to start the genie. Follow the instructions to
complete the setup. NETGEAR Genie checks your hardware setup and guides you through
connecting the modem router to the Internet and adding computers to your network.
Your modem router connects to the Internet when any computer on your network
launches a Web browser to access the Internet. The modem router’s Internet LED
blinks.
View or Change Settings
You can view and change the settings in the following ways:
• Log in to your modem router. To do this you can click the shortcut that was placed
on your desktop during the NETGEAR Genie setup, or use an Internet browser. See Log
In to the Modem Router on page 20.
• Open the Router_Setup.html file that was placed on your desktop during the NETGEAR
Genie setup. This file has setup and system information, the NETGEAR Technical
Support phone number, links to the NETGEAR website, and a modem router login link.
Settings Description
When the NETGEAR Genie is done, your modem router has the following settings. Some of
these can be viewed in Router_Setup.html.
• Language and country as described in Setup Wizard on page 22.
• Internet connection settings as described in Manual Setup (Basic Settings) on page 23.
• Network settings. The NETGEAR Genie steps you through connecting from your
computer to the modem router.

Idle Timeout (In minutes). If you want to change the login timeout, enter a new value in
minutes. This determines how long the modem router keeps the Internet connection
active after there is no Internet activity from the LAN. Entering a value of 0 (zero) means
never log out.
Internet IP Address.
• When a login is required, these fields display:
Get Dynamically from ISP. Your ISP uses DHCP to assign your IP address. Your ISP
automatically assigns these addresses.
Use Static IP Address. Enter the IP address, IP subnet mask, and the gateway IP
address that your ISP assigned. The gateway is the ISP’s modem router to which your
modem router will connect.
• When a login is not required, this field displays:
Use IP Over ATM (IPoA). Your ISP uses classical IP addresses (RFC 1577). Enter the IP
address, IP subnet mask, and gateway IP addresses that your ISP assigned.
Domain Name Server (DNS) Address. The DNS server is used to look up site addresses
based on their names.
• Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your ISP
automatically assigns this address.
• Use These DNS Servers. If you know that your ISP does not automatically transmit DNS
addresses to the modem router during login, select this option, and enter the IP address
of your ISP’s primary DNS server. If a secondary DNS server address is available, enter it
also.
NAT (Network Address Translation). NAT automatically assigns private IP addresses
(10.1.1.x) to LAN-connected devices.
• Enable. Usually NAT is enabled.
• Disable. This disables NAT, but leaves the firewall active. Disable NAT only if you are
sure you do not need it. When NAT is disabled, only standard routing is performed by this
modem. Classical routing lets you directly manage the IP addresses that the modem
router uses. Classical routing should be selected only by experienced users.1
• Disable firewall. This disables the firewall in addition to disabling NAT. With the firewall
disabled, the protections usually provided to your network are disabled.
When no login is required, this field displays:
Router MAC Address. The Ethernet MAC address used by the modem router on the
Internet port. Some ISPs register the MAC address of the network interface card in your
computer when your account is first opened. They will then accept traffic only from the MAC
address of that computer. This feature allows your modem router to use your computer’s
MAC address (this is also called cloning).
1. Disabling NAT reboots the modem router and resets its configuration settings to the factory defaults. Disable NAT
only if you plan to set up the modem router in a setting where you will be manually administering the IP address space
on the LAN side of the modem.
Modem Router Setup

4. If you cannot connect to the modem router, check the Internet Protocol (TCP/IP) properties
in the Network Connections section of your PC Control Panel. They should be set to obtain
both IP and DNS server addresses automatically. See your computer documentation.
Change Password and Login Time-Out
For security reasons, the modem router has its own user name and password that default to
admin and password. You can and should change these to a secure user name and
password that are easy to remember. The ideal password contains no dictionary words from
any language and is a mixture of upper case and lower case letters, numbers, and symbols.
It can be up to 30 characters.
Note: The modem router user name and password are not the same as
the user name and password for logging in to your Internet
connection. See Types of Logins on page 28 for more information
about login types.
To change the password and login time-out:
1. Select Maintenance > Set Password to display the following screen:.
2. Enter the old password.
3. Enter the new password twice.
4. Change the login time-out to a value between 1 and 99 minutes if the default value of 5

inactivity to prevent someone else from accessing the modem router interface when you
step away.
5. Click Apply to save your changes.
Modem Router Setup
28
N300 Wireless ADSL2+ Modem Router DGN2200v3
After changing the password, you are required to log in again to continue the
configuration. If you have backed up the modem router settings previously, you should do
a new backup so that the saved settings file includes the new password. See To back up
the modem router configuration file: on page 59 for information about backing up your
network configuration.
Log Out Manually
The modem router interface provides a Logout command at the bottom of the modem router
menus. Log out when you expect to be away from your computer for a relatively long period
of time.
Types of Logins
There are three separate types of logins that have different purposes. It is important that you
understand the difference so that you know which login to use when.
• Modem router login logs you in to the modem router interface. See Log In to the Modem
Router on page 20 for details about this login.
• ISP login logs you in to your Internet service. Your service provider has provided you with
this login information in a letter or some other way. If you cannot find this login
information, contact your service provider.
• Wi-Fi network name and passphrase logs you in to your wireless network. This login is
preconfigured and can be found on the label on the bottom of your unit. See Chapter 3,
Wireless Settings, for more information.

Protecting your network
This chapter describes how to use the Wireless Settings screens to view and change (if needed)
your wireless network settings. Security features to prevent objectionable content from reaching
your PCs are covered in Chapter 4, Security Settings.
This chapter contains the following sections:
• Wireless Adapter Compatibility
• Preset Security
• Security Basics
• Add Clients (Computers or Devices) to Your Network
• Wireless Settings Screen
• Wireless Guest Networks
Wireless Adapter Compatibility
A wireless adapter is the wireless radio in your PC or laptop that lets the PC or laptop
connect to a wireless network. Most PCs and laptops come with an adapter already installed,
but if it is outdated or slow, you can purchase a USB adapter to plug into a USB port.
Make sure the wireless adapter in each computer in your wireless network supports the
same security settings as the modem router. See Preset Security on page 30 for information
about the modem router’s preconfigured security settings.
Note: If you connect devices to your modem router using WPS as
described in Wi-Fi Protected Setup (WPS) Method on page 32,
those devices assume the security settings of the modem router.
Wireless Settings
30
N300 Wireless ADSL2+ Modem Router DGN2200v3
Preset Security
The modem router comes with preset security. This means that the Wi-Fi network name
(SSID), passphrase, and security option (encryption protocol) are preset in the factory. You
can find the preset SSID and passphrase on the bottom of the unit.
• Wi-Fi network name (SSID) identifies your network so devices can find it.
• Passphrase controls access to your network. Devices that know the SSID and the
passphrase can find your wireless network and connect.
Note: The preset SSID and passphrase are uniquely generated for every
device to protect and maximize your wireless security.
• Security option is the type of security protocol applied to your wireless network. The
security protocol in force encrypts data transmissions and ensures that only trusted
devices receive authorization to connect to your network. The preset security option is
WPA-PSK/WPA2-PSK mixed mode, described in Wireless Security Options on page 31.
The Wireless Settings screen lets you view and change the preset security settings.
However, NETGEAR recommends that you not change your preset security settings. If
you do decide to change your preset security settings, make a note of the new settings and
store it in a safe place where you can easily find it.
Security Basics
Unlike wired network data, wireless data transmissions extend beyond your walls and can be
received by any device with a compatible wireless adapter (radio). For this reason, it is very
important to maintain the preset security and understand the other security features available
to you. Besides the preset security settings described in the previous section, your modem
router has the security features described here and in Chapter 4, Security Settings.
• Turn off wireless connectivity
• Disable SSID broadcast
• Restrict access by MAC address
• Wireless security options
Turn Off Wireless Connectivity
You can turn off the wireless connectivity of the modem router by pressing the Wireless
On/Off button on its front panel . For example, if you use your laptop to wirelessly connect
to your modem router and you take a business trip, you can turn off the wireless portion of the
modem router while you are traveling. Other members of your household who use computers
connected to the modem router through Ethernet cables can still use the modem router.
Wireless Settings
31
N300 Wireless ADSL2+ Modem Router DGN2200v3
Disable SSID Broadcast
By default, the modem router broadcasts its Wi-Fi network name (SSID) so devices can find
it. If you change this setting to not allow the broadcast, wireless devices will not find your
modem router unless they are configured with the same SSID.
Note: Turning off SSID broadcast nullifies the wireless network discovery
feature of some products such as Windows XP, but the data is still
fully exposed to a determined snoop using specialized test
equipment like wireless sniffers. If you allow the broadcast, be sure
to keep wireless security enabled.
Restrict Access by MAC Address
You can enhance your network security by allowing access to only specific PCs based on
their Media Access Control (MAC) addresses. You can restrict access to only trusted PCs so
that unknown PCs cannot wirelessly connect to the modem router. The Wireless Station
MAC address filtering adds additional security protection to the wireless security option that
you have in force. The Access list determines which wireless hardware devices are allowed
to connect to the modem router by MAC address. See Advanced Wireless Settings on
page 84 for the procedure.
Wireless Security Options
A security option is the type of security protocol applied to your wireless network. The
security protocol encrypts data transmissions and ensures that only trusted devices receive
authorization to connect to your network. There are several types of encryption: Wi-Fi
Protected Access II (WPA2), WPA, and Wired Equivalent Privacy (WEP). WPA2 is the latest
and most secure, and is recommended if your equipment supports it. WPA has several
options including pre-shared key (PSK) encryption and 802.1x encryption for enterprises.
Note that it is also possible to disable wireless security. NETGEAR does not recommend this.
You can view or change the wireless security options in the Wireless Settings screen. See
Wireless Settings Screen on page 33.

1. Open the software that manages your wireless connections on the wireless device
(laptop computer, gaming device, iPhone) that you want to connect to your modem
router. This software scans for all wireless networks in your area.
2. Look for your network and select it. If you did not change the name of your network during
the setup process, look for the default Wi-Fi network name (SSID) and select it. The default
Wi-Fi network name (SSID) is located on the product label on the bottom of the modem
router.
3. Enter the modem router passphrase and click Connect. The default modem router
passphrase is located on the product label on the bottom of the modem router.
4. Repeat steps 1–3 to add other wireless devices.
Wi-Fi Protected Setup (WPS) Method
Wi-Fi Protected Setup (WPS) is a standard that lets you easily join a secure wireless network
with WPA or WPA2 wireless security. The modem router automatically sets security for each
computer or device that uses WPS to join the wireless network. To use WPS, make sure that
your wireless devices are Wi-Fi certified and support WPS. NETGEAR products that use
WPS call it Push 'N' Connect.1
Note: If the wireless network name (SSID) changes each time you add a
WPS client, the Keep Existing Wireless Settings check box on the
Advanced Wireless Settings screen has been cleared. See WPS
Settings on page 85 for more information about this setting.
You can use a WPS button or the modem router interface method to add wireless computers
and devices to your wireless network.
To join the wireless network using a WPS button:
1. Press the WPS button on the modem router front panel.
2. Within 2 minutes, press the WPS button on your wireless computer or device, or follow the
WPS instructions that came with the computer. The device is now connected to your modem
router.
3. Repeat steps 1–2 to add other WPS wireless computers or devices.
To use the modem router Interface to add a client:
1. Select Add WPS Client at the top of the modem router menus.
1. For a list of other Wi-Fi-certified products available from NETGEAR, go to http://www.wi-fi.org.

Consider Every Device on Your Network
Before you begin, check the following:
• Every wireless computer has to be able to obtain an IP address by DHCP from the
modem router as described in Use Standard TCP/IP Properties for DHCP on page 18.
• Each computer or wireless adapter in your network must have the same SSID and
wireless mode (bandwidth/data rate) as the modem router. Check that the wireless
adapter on each computer can support the mode and security option you want to use.
• The security option on each wireless device in the network must match the modem router.
For example, if you select a security option that requires a passphrase, be sure to use
same passphrase for each wireless computer in the network.

Firewall Rules to Control Network Access
Your modem router has a firewall that blocks unauthorized access to your wireless network
and permits authorized inbound and outbound communications. Authorized communications
are established according to inbound and outbound rules. The firewall has the following two
default rules. You can create custom rules to further restrict the outbound communications or
more widely open the inbound communications:
• Inbound. Block all access from outside except responses to requests from the LAN side.
• Outbound. Allow all access from the LAN side to the outside.
Set Up Firewall Rules
The Firewall Rules screen lets you configure custom rules to make exceptions to the default
rules. Exceptions can be based on the service or application, source or destination IP
addresses, and time of day. You can log traffic that matches or does not match the rule and
change the order of rule precedence.
All traffic attempting to pass through the firewall is subjected to the rules in the order shown in
the Rules table from the top (highest precedence) to the default rules at the bottom. In some
cases, the order of precedence is important to determine which communications are allowed
into or out of the network.
To set up firewall rules:
1. Select Security > Firewall Rules to display the following screen:
2. To add an outbound rule, click Add under Outbound Services.
For To edit or delete a rule, select its button on the left side and click Edit or Delete.

5. Click Apply to save your settings.
Port Triggering to Open Incoming Ports
Some application servers (such as FTP and IRC servers) send replies back to multiple port
numbers. Using the port triggering function of your router, you can tell the router to open
additional incoming ports when a particular outgoing port originates a session.
An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at
destination port 6667. The IRC server not only responds to your originating source port, but
also sends an “identify” message to your computer on port 113. Using port triggering, you can
tell the router, “When you initiate a session with destination port 6667, you have to 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 to start 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
(for example, 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.
Security Settings
45
N300 Wireless ADSL2+ Modem Router DGN2200v3
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 the relevant user groups or news groups.
Note: Only one computer at a time can use the triggered application.
Port Forwarding to Permit External Host Communications
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 the 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 a browser 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:
Destination address. The IP address of www.example.com, which is the address of your
router.
Destination port number. 80, which is 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.
Security Settings
46
N300 Wireless ADSL2+ Modem Router DGN2200v3
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
the relevant user groups or news groups.
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.
• With port triggering, the router 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 can 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.
Set Up 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 want to make a local web server, FTP
server, or game server visible and available to the Internet.
Use the Port Forwarding/Port Triggering 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.
Before starting, you need to determine which type of service, application, or game you want
to provide, and the local IP address of the computer that will provide the service. The server
computer has to always have the same IP address.
Tip: To ensure that your server computer always has the same IP address,
use the reserved IP address feature of your product.

Application Example: Make 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. In this example, your router will always give your web server an IP
address of 192.168.1.33.
2. In the Port Forwarding/Port Triggering 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. To access your web server from the Internet, a remote user has to 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.

Set Up 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 ports to any computer that needs them and
can close the ports when they are no longer needed.
Note: If you use applications such as multiplayer gaming, peer-to-peer
connections, real-time communications such as instant messaging,
or remote assistance (a feature in Windows XP), you should also
enable Universal Plug and Play (UPnP).
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 news groups.
To enable port triggering:
1. Select Advanced > Port Forwarding/Port Triggering to display the Port
Forwarding/Port Triggering screen.

2. Select the Port Triggering radio button to display the port triggering information.
3. Clear the Disable Port Triggering check box.
Note: If the Disable Port Triggering check box is selected after you
configure port triggering, port triggering is disabled. However, any
port triggering configuration information you added to the router is
retained even though it is not used.
4. In the Port Triggering Timeout field, enter a value up to 9999 minutes. This value controls the
inactivity timer for the designated inbound ports. The inbound ports close when the inactivity
time expires. This is required because the router cannot be sure when the application has
terminated.
To add a port triggering service:
Make sure that you enable port triggering so that the service that you add will be used.

Upgrade the Modem Router Firmware
The modem router firmware (routing software) is stored in flash memory. By default, when
you log in to your modem router, it checks the NETGEAR website for new firmware and alerts
you if there is a newer version.
WARNING!
When uploading firmware to the modem router, do not interrupt
the Web browser by closing the window, clicking a link, or loading
a new page. If the browser is interrupted, it could corrupt the
firmware.
Automatic Firmware Check
When automatic firmware checking is on, the modem router performs the check and notifies
you if an upgrade is available or not as shown here.
To upgrade the firmware:
1. Click Yes to allow the modem router to download and install the new firmware. The
upgrade process could take a few minutes. When the upload is complete, your modem
router restarts.
2. Go to the DGN2200v3 support page at http://www.netgear.com/support.and read the new
firmware release notes to determine whether you need to reconfigure the modem router
after upgrading.
Note: If you get a “Firmware needs to be reloaded” message, it means a
problem has been detected with the modem router’s firmware.
Follow the prompts to correct the problem or see Incorrect Date or
Time on page 107 for a description of the steps.
