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, computers, or a 2.4 GHz cordless phone and
its base.
•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.
ADSL Microfilters
If this is the first time you have cabled a modem 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 inline 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. Examples of devices are telephones, fax machines, answering
machines, and caller ID displays. 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.
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
Hardware Setup
13
N300 Wireless ADSL2+ Modem Router DGN2200v4
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 on page 13)
Plugs into DSL line
.
Figure 5. 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 if you have 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

Modem Router Setup Preparation
You can set up your modem router with the NETGEAR genie automatically, or you can use
the genie menus and screens to set up your modem 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 need to 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
modem router and to check that your Internet configuration is correct. Your Internet service
provider (ISP) should have provided you with all of 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 modem router
automatically logs you in. Make sure that you have the following information:
•The ISP configuration information for your DSL account
•ISP login name and password
•Fixed or static IP address settings (special deployment by ISP; this is rare)
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 supported by the modem router.
Types of Logins and Access
There are 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. For more information
about this login, see Use NETGEAR genie after Installation on page 18.
•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 modem 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 modem router.

Wireless Settings Screen Fields
You can use this screen to view or change the wireless network settings and the security
option.
Wireless Network
Enable SSID Broadcast. This setting allows the modem 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 this check box, and
click Apply.
Enable Wireless Isolation. If this check box is selected, computers or wireless 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.
Region. The location where the modem router is used. Select from the countries in the list. In
the United States, the region is fixed to United States and is not changeable.
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 this happens, experiment with different channels to see which is the
best.
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).
Mode. Up to 145 Mbps is the default setting, which allows 802.11n and 802.11g wireless
devices to join the network. The other settings are Up to 54 Mbps, and Up to 300 Mbps.
Security Options Settings
The Security Options section of the Wireless Settings screen lets you change the security
option and passphrase. NETGEAR recommends that you do not change these settings,
but this section explains how. Do not disable security.
Wireless 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
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. It is also possible to set up a guest network without wireless security.
NETGEAR does recommend this.not
NETGEAR genie Basic Settings
30
N300 Wireless ADSL2+ Modem Router DGN2200v4
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 passphrase for authentication and to 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.
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 implemented through hardware, while WPA-PSK is usually
implemented through software. WPA2-PSK uses a passphrase 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. For help with WPA settings on your wireless computer or device, see the
instructions that came with your product.
Change WPA Security Option and Passphrase
You can change the security settings for your modem router. If you do so, then write down the
new settings and store them in a secure place for future reference.
To change the WPA settings:
1. Select Basic > Wireless Settings.
2. Under Security Options, select the WPA option you want.
3. In the Passphrase field that displays when you select a WPA security option, enter the
network key (password) that you want to use. It is a text string from 8 to 63 characters.

Adding a guest network allows visitors at your home to use the Internet without giving them
your wireless security key.
To set up a guest network:
1. Select .Basic > Guest Network
2. Select any of the following wireless settings:
Enable Guest Network. When this check box is selected, the guest network is enabled,
and guests can connect to your network using the SSID of this profile.

broadcasts its name (SSID) to all wireless stations. Stations with no SSID can adopt the
correct SSID for connections to this access point.
Allow guest to access My Local Network. If this check box is selected, anyone who
connects to this SSID has access to your local network, not just Internet access.
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.
3. Give the guest network a name.
The guest network name is case-sensitive and can be up to 32 characters. You then
manually configure the wireless devices in your network to use the guest network name
in addition to the main SSID.
4. Select a security option from the list.
The security options are described in on page 29.Wireless Security Options

connection, the LED is solid green, and the modem router WPS screen displays a
confirmation message.
WAN Setup
You can use the WAN Setup screen to specify the ADSL or Ethernet port setting for your
Internet connection, though by default the modem router automatically detects the Internet
port. The WAN Setup screen also lets you configure a DMZ (demilitarized zone) server,
change the maximum transmit unit (MTU) size, and enable the modem router to respond to a
ping on the WAN (Internet) port.
To view or change the WAN settings:
1. Select Advanced > Setup > WAN Setup.
2. Specify the settings for your Internet connection.
The fields in this screen are described in the following section.
NETGEAR genie Advanced Home

N300 Wireless ADSL2+ Modem Router DGN2200v4
3. Click Apply.
WAN Setup Screen Fields
The following fields are available:
•WAN Preference. By default this field is set to Auto-Detect so that the modem router
automatically detects if the Internet connection is through the ADSL port or the
WAN/Ethernet port 4. You can use this field to select Must use DSL WAN or Must use
Ethernet WAN.
•Use port 4 as. By default, Auto-Detect is selected so that the modem router detects if
Ethernet port 4 is used as a LAN or WAN port. For example, if you connect a computer to
Ethernet port 4, then it works as a LAN port. You can select LAN or WAN if you do not
want to use the auto-detect setting.
•Disable Port Scan and DoS Protection. DoS protection protects your LAN against
denial of service attacks such as Syn flood, Smurf Attack, Ping of Death, Teardrop Attack,
UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. This should be
disabled only in special circumstances.
•Default DMZ Server. This feature is sometimes helpful when you are playing online
games or videoconferencing. Be careful when using this feature because it makes the
firewall security less effective. See the following section, Default DMZ Server.
•Respond to Ping on Internet Port. If you want the modem 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 modem router to be discovered. Do not select this check box
unless you have a specific reason.
•Disable IGMP Proxying. The IGPM proxying feature lets a LAN computer receive the
multicast traffic directed to it from the Internet. Selecting this check box prevents this from
occurring.
•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. This is rarely required. You should change the setting in this
field only if you are sure that it is necessary for your ISP connection. See Change the
MTU Size on page 38.
•NAT Filtering. Network Address Translation (NAT) determines how the modem router
processes inbound traffic. Secured NAT provides a secured firewall to protect the
computers on the LAN from attacks from the Internet, but might prevent some Internet
games, point-to-point applications, or multimedia applications from functioning. Open
NAT provides a much less secured firewall, but allows almost all Internet applications to
function.
•Disable SIP ALG. The Session Initiation Protocol (SIP) Application Level Gateway (ALG)
is enabled by default to optimize VoIP phone calls that use the SIP. Select the Disable
SIP ALG check box to disable the SIP ALG. Disabling the SIP ALG might be useful when
you are running certain applications.

N300 Wireless ADSL2+ Modem Router DGN2200v4
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 modem router recognizes some of these applications and works 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 modem router discards traffic from the Internet that is not a response to one of your
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 modem 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. screen.
2. Select the Default DMZ Server check box.
3. Type the IP address.
4. Click Apply.

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 just 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
NETGEAR genie Advanced Home
39
N300 Wireless ADSL2+ Modem Router DGN2200v4
-Yahoo email
-MSN portal
-America Online’s DSL service
•You use VPN and have severe performance problems.
•You used a program to optimize MTU for performance reasons, and now you have
connectivity or performance problems.
Note: An incorrect MTU setting can cause Internet communication
problems. For example, 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
willing to experiment, you can gradually reduce the MTU from the maximum value of 1500
until the problem goes away. The following table describes common MTU sizes and
applications.
Table 2. Common MTU sizes
MTU Application
1500 The largest Ethernet packet size. This setting is typical for connections that do not use
PPPoE or VPN, and is the default value for NETGEAR modem routers, adapters, and
switches.
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)
1468 Used in some DHCP environments.
1460 Usable by AOL if you do not have large email attachments, for example.
1436 Used in PPTP environments or with VPN.
1400 Maximum size for AOL DSL.
576 Typical value to connect to dial-up ISPs.
To change the MTU size:
1. Select Advanced > Setup > WAN Setup.
2. In the MTU Size field, enter a value from 64 to 1500.

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 modem router is
shipped preconfigured to use private IP addresses on the LAN side and to act as a DHCP
server. The modem router’s default LAN IP configuration is:
•LAN IP address. 192.168.0.1
•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.
By default, the modem router acts as a DHCP server. The modem 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 modem router. The modem router tests
each address before it is assigned to avoid duplicate addresses on the LAN. For most
applications, the default DHCP and TCP/IP settings of the modem router are satisfactory.
The modem router delivers the following parameters to any LAN device that requests DHCP:
•IP address
•Subnet mask
•Gateway IP address (the modem router’s LAN IP address)
•Primary DNS server (if specified in the Internet Setup screen), otherwise, the modem
router’s LAN IP address)
•Secondary DNS server if you entered this in the Internet Setup screen
If you change the LAN IP address of the modem router while connected through the browser,
you are disconnected from the network.
To change the LAN settings:
1. Select .Advanced > Setup > LAN Setup
NETGEAR genie Advanced Home

LAN Setup Screen Settings
The following settings are available.
Device Name. By default, this is DGN2200v4 (the modem router model). You can change
it to another name if you prefer.
LAN TCP/IP Setup
•IP Address. The LAN IP address of the modem router.
•IP Subnet Mask. The LAN subnet mask of the modem router. Combined with the IP
address, the IP subnet mask allows a device to know which other addresses are local to
it, and which addresses have to be reached through a gateway or modem router.
•RIP Direction. Router Information Protocol (RIP) allows the modem router to exchange
routing information with other routers. This setting controls how the modem router sends
and receives RIP packets. Both is the default setting. With the Both or Out Only setting,
the modem router broadcasts its routing table periodically. With the Both or In Only
setting, the modem 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 modem 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
Usually, this check box is selected so that the modem 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 modem router.
•Ending IP Address. Specify the end of the range for the pool of IP addresses in the
same subnet as the modem 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 modem router’s DHCP server. Assign
reserved IP addresses to servers that require permanent IP settings. See Address
Reservation on page 42.
NETGEAR genie Advanced Home

N300 Wireless ADSL2+ Modem Router DGN2200v4
Specify DHCP Server Settings
By default, the modem router is set up as a DHCP server. You can specify the range of
addresses that the modem router assigns. You can also use another device on your network
as the DHCP server, or specify the network settings of all of your computers.
To specify the pool of IP addresses that the modem router assigns:
1. Select .Advanced > LAN Setup
2. Make sure that the Use Router as a DHCP Server check box is selected.
3. Specify the range of IP addresses.
For example, using the default addressing scheme, define a range between 192.168.0.2
and 192.168.0.254, 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
addresses 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
addresses in the same subnet as the modem router.

Address Reservation
When you specify a reserved IP address for a computer on the LAN, that computer always
receives the same IP address each time it accesses the modem 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. Select .Advanced > Setup > LAN Setup
2. In the Address Reservation section of the screen, click the Add button.
3. In the IP Address field, type the IP address to assign to the computer or server.

address you want to edit or delete. Then c .lick or Edit Delete
Quality of Service (QoS) Setup
QoS is an advanced feature that can be used to prioritize some types of traffic ahead of
others. The modem router can provide QoS prioritization over the wireless link and on the
Internet connection.
WMM QoS for Wireless Multimedia Applications
The modem router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to prioritize
wireless voice and video traffic over the wireless link. WMM QoS provides prioritization of
wireless data packets from different applications based on four access categories: voice,
video, best effort, and background. For an application to receive the benefits of WMM QoS,
both it and the client running that application have to 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.
To disable WMM QoS:
1. Select . Advanced > Setup > QoS Setup
2. Clear the Enable WMM check box
3. Click Apply.

File-Sharing Scenarios
You can share files on the USB drive for a wide variety of business and recreational
purposes. The files can be any Windows, Mac, or Linux file type including text, Word,
PowerPoint, Excel, MP3, pictures, and multimedia files. USB drive applications include:
•Sharing multimedia with friends and family such as MP3 files, pictures, and other
multimedia with local and remote users.
•Sharing resources on your network. You can store files in a central location so that you do
not have to power up a computer to perform local sharing. In addition, you can share files
between Macintosh, Linux, and Windows computers by using the USB drive as a
go-between across the systems.
•Sharing files such as Word documents, PowerPoint presentations, and text files with
remote users.
A few common uses are described in the following sections.
Share Photos
You can create your own central storage location for photos and multimedia. This method
eliminates the need to log in to (and pay for) an external photo-sharing site.
To share files with your friends and family:
1. Insert your USB drive into the USB port on the modem router either directly or with a
USB cable.
Computers on your local area network (LAN) can automatically access this USB drive
using a web browser or Microsoft Networking.

server.
•One family member has photos on a Macintosh computer that she wants to print.
•The photo-capable color printer is directly attached to a PC, but not shared on the
network.
•The Mac and PC are not visible to each other on the network.
USB Storage
53
N300 Wireless ADSL2+ Modem Router DGN2200v4
To print photos from a Mac on the printer attached to a PC:
1. On the Mac, access the USB drive by typing \\readyshare in the address field of a web
browser. Then copy the photos to the USB drive.
2. On the PC, use a web browser or Microsoft Networking to copy the files from the USB drive
to the PC. Then print the files.
Share Large Files over the Internet
Sending files that are larger than 5 MB can pose a problem for many email systems. The
modem router allows you to share large files such as PowerPoint presentations or .zip files
over the Internet. FTP can be used to download shared files from the modem router.
Sharing files with a remote colleague involves the following considerations:
•There are two user accounts: admin and guest. The password for admin is the same one
that you use to access the modem router. By default, it is . The guest user password
account has no password.
•On the FTP site, the person receiving the files uses the guest user account and enters
the password. (FTP requires that you type something in the password field.)
•Be sure to select the check box in the USB Storage (Advanced FTP (via Internet)
Settings) screen. This option supports both downloading and uploading of files.
You can enable the HTTP (via Internet) option on the USB Storage (Advanced Settings)

Set Up 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
•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.
You can add rules to further restrict the outbound communications or more widely open the
inbound communications. 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.
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 bottom. In some cases, the order of
precedence determines which communications are allowed into or out of the network.
To set up firewall rules:
1. Select .Advanced > Security > Firewall Rules
2. You can add, edit, or delete a rule.
•To add an outbound rule, click Add under Outbound Services.
•To edit or delete a rule, select its button on the left side and click or .Edit Delete
3. (Optional) Change the order of precedence:
a. MoveSelect the button on the left side of the rule and click .
b. OKAt the prompt, enter the number of the new position and click .
4. (Optional) To open or close instant messaging, select one of the following radio buttons:
•Close IM Ports. Disables instant messaging traffic.
•Open IM Ports. Enables instant messaging traffic. IM ports are open by default.

Port Triggering to Open Incoming Ports
Some application servers (such as FTP and IRC servers) send replies to multiple port
numbers. Using the port triggering function of your modem router, you can tell the modem
router to open more 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 modem 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 modem router.
3. Your modem router creates an entry in its internal session table describing this
communication session between your computer and the IRC server. Your modem 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 modem 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 modem 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 modem router with destination port 113.
6. Upon receiving the incoming message to destination port 33333, your modem router
checks its session table to determine whether there is an active session for port number
33333. Finding an active session, the modem 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 modem router checks
its session table and learns that there is an active session for port 113, associated with your
computer. The modem 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 eventually senses a period of modem router
inactivity in the communications. The modem 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 the relevant user groups or news groups.

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 modem
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 modem 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
192.168.0.123.” 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 modem 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
modem 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
modem router.
2. Your modem 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 192.168.0.123. Therefore,
your modem router modifies the destination information in the request message:
The destination address is replaced with 192.168.0.123.
Your modem router then sends this request message to your local network.
3. Your web server at 192.168.0.123 receives the request and composes a return message
with the requested web page data. Your web server then sends this reply message to your
modem router.
4. Your modem 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.
