Position Your Router
The 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 router. For example, the
thickness and number of walls the wireless signal passes through can limit the range. For
best results, place your 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 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, computers, 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).
Cable Your Router
The installation guide that came in the box includes a cabling diagram. This section walks
you through cabling with detailed illustrations.
To connect the router, the computer, and the modem:
1. Unplug and turn off the broadband modem.
2. Locate the cable (A) that connects your computer to the modem.

• Router Setup Preparation
• Types of Logins
• NETGEAR genie Setup

Router Setup Preparation
You can set up your router with the NETGEAR genie automatically, or you can use the genie
menus and screens to set up your router manually. Before you start the setup process, get
your ISP information and make sure the computers and devices in the network have the
settings described here.
Use Standard TCP/IP Properties for DHCP
If you set up your computer to use a static IP address, you must change the settings so that it
uses Dynamic Host Configuration Protocol (DHCP).
Gather ISP Information
If you have DSL broadband service, you might need the following information to set up your
router and to check that your Internet configuration is correct:
• The ISP configuration information for your DSL account
• ISP login name and password
• Fixed or static IP address settings (special deployment by ISP; this situation is rare)
When your Internet service starts, your Internet service provider (ISP) typically gives you all
the information needed to connect to the Internet. If you cannot locate this information, ask
your ISP to provide it. When your Internet connection is working, 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 router automatically logs you in.
Wireless Devices and Security Settings
Make sure that the wireless device or computer that you are using supports WPA or WPA2
wireless security, which is the wireless security that the router uses.
Access the Router
15
Page 16
N300 Wireless Router JWNR2000v3
Types of Logins
Different types of logins have different purposes:
• Router login. Logs you in to the router interface from NETGEAR genie. For more
information for details about this login, see
page 17.
• 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.
• Wireless network key or password. Your router is preset with a unique wireless
network name (SSID) and password for wireless access. This information is on the label
on the bottom of your router.
It is important that you understand the differences between the login types so that you know
which login to use when.
Use NETGEAR genie after Installation on
NETGEAR genie Setup
NETGEAR genie runs on any device with a web browser. It is the easiest way to set up the
router because it automates many of the steps and verifies that those steps have been
successfully completed. It takes about 15
minutes to complete.
To use NETGEAR genie to set up your router:
1. Turn on the router, if not done yet.
2. Make sure that your device is connected with an Ethernet cable (wired) or wirelessly (with
the preset security settings listed on the bottom label) to your router.
3. Launch your Internet browser.
• The first time that you set up the Internet connection for your router, the browser goes
to http://www.routerlogin.net, and the NETGEAR genie screen displays.
• If you already used the NETGEAR genie, type http://www.routerlogin.net in the
address field for your browser to display the NETGEAR genie screen. See
NETGEAR genie after Installation on page 17.
4. Follow the onscreen instructions to complete NETGEAR genie setup.
NETGEAR genie guides you through connecting the router to the Internet.
If the browser cannot display the web page, try these troubleshooting tips:
Use
• Make sure that the computer is connected to one of the four LAN Ethernet ports, or
wirelessly to the router.
• Make sure that the router has full power, and that its Wireless LED is lit.
• Close and reopen the browser to make sure that the browser does not cache the
previous page.
• Browse to http://www.routerlogin.net.
Access the Router

Wireless Settings Screen Fields
You can configure the following wireless settings:
• Region. The location where the router is used. Select from the countries in the
drop-down menu. In the United States, the region is fixed to United States and is not
changeable.
• Enable SSID Broadcast. This setting allows the router to broadcast its SSID so wireless
stations can see this wireless name (SSID) in their scanned network lists. This check box
is selected by default. To turn off the SSID broadcast, clear the Enable SSID Broadcast
check box and click Apply.
• Enable Wireless Isolation. If this check box is selected, wireless computers or devices
that join the network can use the Internet but cannot access each other or access
Ethernet devices on the network.
• Name (SSID). The SSID is also known as the wireless network name. Enter a
32-character (maximum) name in this field. This field is case-sensitive. The default SSID
is randomly generated, and NETGEAR strongly recommends that you do not change
this setting.
• Channel. This setting is the wireless channel the gateway uses. Enter a value from 1
through 13. (For products in the North America market, only Channels 1 through 11 can
be operated.) Do not change the channel unless you experience interference (shown by
lost connections or slow data transfers). If you experience interference, experiment with
different channels to see which is the best.
• Mode:
- Up to 54 Mbps. This legacy mode uses a maximum speed of Mbps for b/g networks.
- Up to 150 Mbps. (Default) This neighbor-friendly mode does not interfere with
neighboring wireless networks.
- Up to 300 Mbps. Performance mode uses the maximum wireless-N speed of up to
300 Mbps.
• Security Options. The Security Options section of the Wireless Settings screen lets you
change the security option and password. Do not disable security. For more information
about the security options, see
Security Options on page 28.
Note: WEP is a legacy security setting. NETGEAR recommends that you
use WPA2 or WPA security unless you have legacy wireless
equipment that supports only WEP. WEP encryption is available only
when the Mode setting is Up to 54 Mbps.
Security Options
A 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
NETGEAR genie Basic Settings
28
Page 29
N300 Wireless Router JWNR2000v3
receive authorization to connect to your network. Wi-Fi Protected Access (WPA) has several
options including pre-shared key (PSK) encryption.
This section presents an overview of the security options and provides guidance on when to
use which option.
WEP Encryption
WEP uses an old encryption method and can be easily decoded with today’s powerful
computers. Use this mode only when you have a very old legacy wireless client that does not
support WPA-PSK. The Wi-Fi Alliance highly recommends against using WEP and plans to
make it obsolete. If you do decide to use WEP, see
Change the WEP Security Option on
page 29 for the procedure.
WPA Encryption
WPA encryption is built into all hardware that has the Wi-Fi-certified seal. This seal means
that the product is authorized by the Wi-Fi Alliance (
http://www.wi-fi.org/) because it complies
with the worldwide single standard for high-speed wireless local area networking.
WPA uses a password to perform authentication and generate the initial data encryption
keys, then it dynamically varies the encryption key. WPA-PSK uses Temporal Key Integrity
Protocol (TKIP) data encryption, implements most of the IEEE 802.11i standard, and works
with all wireless network interface cards, but not all wireless access points. It is superseded
by WPA2-PSK.
WPA2-PSK is stronger than WPA-PSK. It is advertised to be theoretically indecipherable due
to the greater degree of randomness in encryption keys that it generates. WPA2-PSK gets
higher speed because it is usually implemented through hardware, while WPA-PSK is usually
implemented through software. WPA2-PSK uses a password to authenticate and generate
the initial data encryption keys. Then it dynamically varies the encryption key.
WPS-PSK + WPA2-PSK Mixed Mode can provide broader support for all wireless clients.
WPA2-PSK clients get higher speed and security, and WPA-PSK clients get decent speed
and security.
Change the WEP Security Option
You can change the WEP security settings for your router. If you do so, then write down the
new settings and store them in a secure place for future reference. For more information
about WEP, see

games or videoconferencing. Be careful when using this feature because it makes the
firewall security less effective. See the following section,
Default DMZ Server, for more
details.
• Respond to Ping on Internet Port. If you want the router to respond to a ping from the
Internet, select this check box. Use this feature only as a diagnostic tool because it allows
your router to be discovered. Do not select this check box unless you have a specific
reason.
• Disable IGMP Proxying. IGMP proxying allows a computer on the local area network
(LAN) to receive the multicast traffic it is interested in from the Internet. If you do not need
this feature, you can select this check box to disable it.
• MTU Size (in bytes). The normal MTU (maximum transmit unit) value for most Ethernet
networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs, you might
need to reduce the MTU. Reducing the MTU is rarely required, and should not be done
unless you are sure that it is necessary for your ISP connection. See
Change the MTU
Size on page 44.
• 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 it allows almost all Internet applications to
function.
• Disable SIP ALG. Some SIP (Session Initiation Protocol) applications have their own
way to work around the NAT firewall issue, and the SIP ALG (Application Layer Gateway)
would conflict with those solutions. In most cases, you do not have to disable the SIP
ALG. However, if your SIP applications cannot work with the router, you can disable the
SIP ALG and try the applications again. Select the check box to disable SIP ALG.

correctly with them, but other applications might not function well. In some cases, one local
computer can run the application correctly if that computer’s IP address is entered as the
default DMZ server.
WARNING:
DMZ servers pose a security risk. A computer designated as the
default DMZ server loses much of the protection of the firewall and
is exposed to exploits from the Internet. If compromised, the DMZ
server computer can be used to attack other computers on your
network.
The router usually detects and discards incoming traffic from the Internet that is not a
response to one of your local computers or a service that you have set up in the Port
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have the router
forward the traffic to one computer on your network. This computer is called the default DMZ
server.
To set up a default DMZ server:
1. Select ADVANCED > Setup > WAN Setup.
The WAN Setup screen displays.

Change the MTU Size
The maximum transmission unit (MTU) is the largest data packet a network device transmits.
When one network device communicates across the Internet with another, the data packets
travel through many devices along the way. If a device in the data path has a lower MTU
setting than the other devices, the data packets are split or “fragmented” to accommodate the
device with the smallest MTU.
The best MTU setting for NETGEAR equipment is often the default value. In some situations,
changing the value fixes one problem but causes another. Leave the MTU unchanged unless
one of these situations occurs:
• You have problems connecting to your ISP or other Internet service, and the technical
support of either the ISP or NETGEAR recommends changing the MTU setting. These
web-based applications might require an MTU change:
- A secure website that does not open, or displays only part of a web page
- Yahoo email
- MSN portal

Note: An incorrect MTU setting can cause Internet communication
problems. For instance, you might not be able to access certain
websites, frames within websites, secure login pages, or FTP or
POP servers.
If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are

LAN Setup
The LAN Setup screen allows configuration of LAN IP services such as Dynamic Host
Configuration Protocol (DHCP) and Routing Information Protocol (RIP).
The router is shipped preconfigured to use private IP addresses on the LAN side and to act
as a DHCP server. Following is the router’s default LAN IP configuration:
• 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 are suitable for most applications. If your network requires a dif
scheme, you can change these settings in the LAN Setup screen.
Note: If you change the LAN IP address of the router while connected
through the browser, you will be disconnected. You must open a
new connection to the new IP address and log in again.

LAN Setup Screen Settings
You can configure the following LAN settings:
• Device Name. This is the abbreviated name of the modem router.
• LAN TCP/IP Setup:
• 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. Router Information Protocol (RIP) allows a router to exchange routing
information with other routers. This setting controls how the router sends and receives
RIP packets. Both is the default setting. With the Both or Out Only setting, the router
broadcasts its routing table periodically. With the Both or In Only setting, the router
incorporates the RIP information that it receives.
• RIP Version. This setting controls the format and the broadcasting method of the RIP
packets that the router sends. It recognizes both formats when receiving. By default,
the RIP function is disabled.
- RIP-1 is universally supported. It is adequate for most networks, unless you have
an unusual network setup.
- RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in
RIP-2 format. RIP-2B uses subnet broadcasting. RIP-2M uses multicasting.
• Use Router as a DHCP Server. This check box is selected by default so that the router
functions as a Dynamic Host Configuration Protocol (DHCP) server.
- Starting IP Address. Specify the start of the range for the pool of IP addresses in
the same subnet as the router.
- Ending IP Address. Specify the end of the range for the pool of IP addresses in
the same subnet as the router.
• Address Reservation. When you specify a reserved IP address for a computer on the
LAN, that computer receives the same IP address each time it accesses the router’s
DHCP server. Assign reserved IP addresses to servers that require permanent IP
settings.
Use the Router as a DHCP Server
By default, the router acts as a DHCP server. The router assigns IP, DNS server, and default
gateway addresses to all computers connected to the LAN. The assigned default gateway
address is the LAN address of the router. The router assigns IP addresses to the attached
computers from a pool of addresses specified in this screen. Each pool address is tested
before it is assigned to avoid duplicate addresses on the LAN. For most applications, the
default DHCP and TCP/IP settings of the router are satisfactory.
The router delivers the following parameters to any LAN device that requests DHCP:
• An IP address from the range you have defined
genie Advanced Home
47
Page 48
N300 Wireless Router JWNR2000v3
• 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 specify the pool of IP addresses that the modem router assigns:
1. Select ADVANCED > Setup > LAN Setup.
2. Make sure that the Use Router as DHCP Server check box is selected.
3. Specify the range of IP addresses.
For example, using the default addressing scheme, define a range between 192.168.1.2
and 192.168.1.254, although you might want to save part of the range for devices with
fixed addresses.
• In the Starting IP Address field, specify the start of the range for the pool of IP address
in the same subnet as the modem router.
• In the Ending IP Address field, specify the end of the range for the pool of IP address
in the same subnet as the modem router.

Enable WMM QoS for Wireless Multimedia Applications
The router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to prioritize wireless
voice and video traffic over the wireless link. WMM QoS provides prioritization of wireless
data packets from different applications based on four access categories: voice, video, best
effort, and background. For an application to receive the benefits of WMM QoS, both the
application and the client running that application must have WMM enabled. Legacy
applications that do not support WMM and applications that do not require QoS are assigned
to the best effort category, which receives a lower priority than voice and video.
WMM QoS is enabled by default. You can disable it in the QoS Setup screen by clearing the
Enable WMM check box and clicking Apply.
Set Up QoS for Internet Access
You can give prioritized Internet access to the following types of traffic:
• Specific applications
• Specific online games
• Individual LAN (Ethernet) ports of the router
• A specific device by MAC address
To specify prioritization of traffic, create a policy for the type of traffic and add the policy to the
QoS Policy table in the QoS Setup screen. For convenience, the QoS Policy table lists many
common applications and online games that can benefit from QoS handling.

Block Services (Port Filtering)
Services are functions that server computers perform 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 the Internet sends
a request for service to a server computer, 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 the destination port number 80 is an HTTP
(web server) request.
The service numbers for many common protocols are defined by the Internet Engineering
ask Force (IETF at http://www.ietf.org/) and published in RFC1700, “Assigned Numbers.”
T
Service numbers for other applications are typically chosen from the range 1024–65535 by
the authors of the application. Although the router already holds a list of many service port
numbers, you are not limited to these choices. You can often determine port number
information by contacting the publisher of the application, by asking user groups or
newsgroups, or by searching.
The Block Services screen lets you add and block specific Internet services by computers on
your network.
This feature is called service blocking or port filtering. To add a service for
blocking, first determine which port number or range of numbers the application uses.

Wireless Repeating Function
You can configure the router to be used as a wireless access point (AP), which enables it to
act as a wireless repeater. A wireless repeater connects to another wireless router as a client
where the network to which it connects becomes the ISP service.
Note: If you use the wireless repeating function, select either WEP or
None as a security option in the Wireless Settings screen. The WEP
option displays only if you select the wireless mode Up to 54 Mbps in
the Wireless Settings screen.
Wireless repeating is a type of wireless distribution system (WDS). A WDS allows a wireless
network to be expanded through multiple access points instead of using a wired backbone to
link them.
The following figure shows a wireless repeating scenario.

The router is always in dual-band concurrent mode, unless you turn off one radio. If you
enable the wireless repeater in either radio band, the wireless base station or wireless
repeater cannot be enabled in the other radio band. However, if you enable the wireless
base station in either radio band and use the other radio band as a wireless router or
wireless base station, dual-band concurrent mode is not affected.
For you to set up a wireless network with WDS, both access points must meet the
following conditions:
• Both access points must use the same SSID, wireless channel, and encryption mode.
• Both access points must be on the same LAN IP subnet.
That is, all the access point
LAN IP addresses are in the same network.
• All LAN devices (wired and wireless computers) must be configured to operate in the

Port Forwarding and Triggering
By default, the router blocks inbound traffic from the Internet to your computers except replies
to your outbound traffic. You might need to create exceptions to this rule for these 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 your router does not
recognize their replies.
Your router provides two features for creating these exceptions: port forwarding and port
triggering. The next sections provide background information to help you understand how
port forwarding and port triggering work, and the differences between the two.
Remote Computer Access Basics
When a computer on your network needs to access a computer on the Internet, your
computer sends your router a message containing the source and destination address and
process information. Before forwarding your message to the remote computer, your router
must modify the source information and create and track the communication session so that
replies can be routed back to your computer.
The following is an example of normal outbound traffic and the resulting inbound responses:
1. You open a browser and your operating system assigns port number 5678 to this
browser session.
2. You type http://www.example.com into the URL field, and your computer creates a web page
request message with the following address and port information:
• Source address. Your computer’s IP address.
• Source port number. 5678, which is the browser session.
• Destination address. The IP address of www.example.com, which your computer
finds by asking a DNS server.
• Destination port number. 80, which is the standard port number for a web server
process.
The request message is sent 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 step 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 assigned by the router, such as
33333. This step is necessary because two computers could independently be using
the same session number.
Advanced Settings
82
Page 83
N300 Wireless Router JWNR2000v3
Your router then sends this request message through the Internet to the web server at
www.example.com.
4. The web server at www.example.com composes a return message with the requested web
page data. The return message contains the following address and port information.
• Source address. The IP address of www.example.com.
• Source port number. 80, which is the standard port number for a web server
process.
• Destination address. The public IP address of your router.
• Destination port number. 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 to restore the original address information that was
replaced by NAT. Your router sends this reply message to your computer, which displays
the web page from www.example.com. The message now contains the following address
and port information:
• Source address. The IP address of www.example.com.
• Source port number. 80, which is the standard port number for a web server
process.
• Destination address. Your computer’s IP address.
• Destination port number. 5678, which is the browser session that made the initial
request.
6. When you finish your browser session, your router eventually detects 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.
Port Triggering to Open Incoming Ports
In the preceding example, requests are sent to a remote computer by your router from a
particular service port number. Replies from the remote computer to your router are directed
to that port number. If the remote server sends a reply to a different port number, your router
does not recognize it and discards it. However, some application servers (such as FTP and
IRC servers) send replies to multiple port numbers. Using the port triggering function of your
router, you can tell the router to open additional incoming ports when a particular outgoing
port originates a session.
An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at
destination port 6667. The IRC server not only responds to your originating source port, but
also sends an “identify” message to your computer on port 113. Using port triggering, you can
tell the router, “When you initiate a session with destination port 6667, you must also allow
incoming traffic on port 113 to reach the originating computer.” Using steps similar to the
preceding example, the following sequence shows the effects of the port triggering rule that
you defined:
1. You open an IRC client program to start a chat session on your computer.
Advanced Settings
83
Page 84
N300 Wireless Router JWNR2000v3
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, 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 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
Advanced Settings
84
Page 85
N300 Wireless Router JWNR2000v3
192.168.1.123.” The following sequence shows the effects of the port forwarding rule you
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.
4. Your router performs NAT on the source IP address, and sends this request message
through the Internet to the remote computer, which displays the web page from
www.example.com.
To configure port forwarding, you need to know which inbound ports the application needs.
You can usually determine this information by contacting the publisher of the application or
the relevant user groups and 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.
• Port triggering does not require that you 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, determine which type of service, application, or game you want to provide.

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.
In this example, your router always gives 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.
For more information, see Dynamic DNS on page 90.
To access your web server from the Internet, a remote user must know the IP address
that your ISP assigned. 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.
Advanced Settings
88
Page 89
N300 Wireless Router JWNR2000v3
Port forwarding creates a static mapping of a port number or range to a single local
computer. Port triggering can dynamically open ports to any computer that needs them and
can close the ports when they are no longer needed.
Note: If you use applications such as multiplayer gaming, peer-to-peer
connections, real-time communications such as instant messaging,
or remote assistance (a feature in Windows XP), you should also
enable Universal Plug and Play (UPnP) according to the instructions
in Universal Plug and Play on page 94.
To set up port triggering, you must know which inbound ports the application needs and the
number of the outbound port that will trigger the opening of the inbound ports.
You can

Dynamic DNS
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. This type
of service lets you register your domain to their IP address and forwards traffic directed at
your domain to your frequently changing IP address.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic
DNS service does not work because private addresses are not routed on the Internet.
Your router contains a client that can connect to the Dynamic DNS service provided by

Static Routes
Static routes provide additional routing information to your router. Typically, you do not need
to add static routes. You configure static routes only for unusual cases such as multiple
routers or multiple IP subnets 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.
• Y
ou 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.
• Y
our company’s network address is 134.177.0.0.
Advanced Settings
91
Page 92
N300 Wireless Router JWNR2000v3
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 because the ISDN router is on the LAN.
To set up a static route:
1. Select ADV
ANCED > Advanced Setup > Static Routes.

• 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 can 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 four hops. The default value is fine for most home
networks. If you notice that some devices are not being updated or reached correctly,
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.

Quick Tips
This section describes tips for troubleshooting some common problems.
Sequence to Restart Your Network
Be sure to restart your network in this sequence:
1. Turn off and unplug the modem.
2. Turn off the router and computers.
3. Plug in the modem and turn it on. Wait two minutes.
4. Turn on the router and wait two minutes.
5. Turn on the computers.
Check Ethernet Cable Connections
Make sure that the Ethernet cables are securely plugged in.
The Internet LED on the router is on if the Ethernet cable connecting the router and the
modem is plugged in securely and the modem and router are turned on.
For each powered-on computer connected to the router by an Ethernet cable, the
corresponding numbered router LAN port LED is lit.
Wireless Settings
Make sure that the wireless settings in the computer and router match exactly.
For a wirelessly connected computer, the wireless network name (SSID) and wireless
security settings of the router and wireless computer must match exactly.
If you set up an access list in the Advanced Wireless Settings screen, you must add each
wireless computer’s MAC address to the router’s access list.
Network Settings
Make sure that the network settings of the computer are correct.
Wired and wirelessly connected computers must have network (IP) addresses on the same
network as the router. The simplest method is to configure each computer to obtain an IP
address automatically using DHCP.
Some cable modem service providers require you to use the MAC address of the computer
initially registered on the account. You can view the MAC address in the Attached Devices
screen.

Troubleshoot with the LEDs
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power LED is lit.
2. After approximately 30 seconds, verify the following:
• The Power LED is solid green.
• The Internet LED is lit.
• A numbered LAN port LED is lit for any local port that is connected to a computer. A lit
LAN port LED indicates that a link has been established to the connected device.
The LEDs on the front panel of the router can be used for troubleshooting.
Power LED Is Off
Check the following:
• Make sure that the power cord is securely connected to your router and that the power
adapter is securely connected to a functioning power outlet.
• Check that you are using the 5 VDC, 1A power adapter that NETGEAR supplied for this
product.
If the error persists, you have a firmware or hardware problem. For recovery instructions or
help with a hardware problem, contact technical support at
www.netgear.com/support.
Internet or LAN Port LEDs Are Off
If either the Internet LED or the LAN port LEDs do not light when the Ethernet connection is
made, check the following:
• Make sure that the Ethernet cable connections are secure at the router and at the modem
or computer.
• Make sure that power is turned on to the connected modem or computer.
• Be sure that you are using the correct cable:
When connecting the router’s Internet port to a cable or DSL modem, use the cable that
was supplied with the cable or DSL modem. This cable could be a standard
straight-through Ethernet cable or an Ethernet crossover cable.
Wireless LED Is Off
If the Wireless LED stays off, use NETGEAR genie to turn on the wireless radio. For more

Cannot Log In to the Router
If you are unable to log in to the router from a computer on your local network, check the
following:
• If you are using an Ethernet-connected computer, check the Ethernet connection
between the computer and the router as described in an earlier section.
• Make sure that your computer’s IP address is on the same subnet as the router. If you are
using the recommended addressing scheme, your computer’s address should be in the
range of 192.168.1.2 to 192.168.1.254.
• If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and
Mac OS generate and assign an IP address if the computer cannot reach a DHCP server.
These autogenerated addresses are in the range of 169.254.x.x. If your IP address is in
this range, check the connection from the computer to the router and reboot your
computer.
• If your router’s IP address was changed and you do not know the current IP address,
clear the router’s configuration to factory defaults. Restoring the factory default
configuration sets the router’s IP address to 192.168.1.1. For more information, see
Factory Settings on page 108.
• Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh to be sure that the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure that you are using the correct login information. The factory default login name
is admin and the password is password. Make sure that Caps Lock is off when you enter
this information.
• If you are attempting to set up your NETGEAR router as an additional router behind an
existing router in your network, consider replacing the existing router. NETGEAR does
not support such a configuration.
• If you are attempting to set up your NETGEAR router as a replacement for an ADSL
gateway in your network, the router cannot perform many gateway services. For
example, the router cannot convert ADSL or cable data into Ethernet networking
information. NETGEAR does not support such a configuration.
