Position Your Gateway

The gateway lets you access your network 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 gateway. For example, the thickness and number of walls the wireless signal passes through can limit the range.
Additionally, other wireless access points in and around your home might affect your gateway’ any other device that emits a wireless signal for network access.
Position your gateway according to the following guidelines:
• Place your gateway near the center of the area where your computers and other devices
• Make sure that the gateway is within reach of an

Connect to the Network

You can connect to the gateway’s network through a wired or WiFi connection. If you set up your computer to use a static IP address, change the settings so that it uses Dynamic Host Configuration Protocol (DHCP).
Wired Connection
You can connect your computer to the gateway using an Ethernet cable and join the gateway’s local area network (LAN).
To connect your computer to the gateway with an Ethernet cable:
1. Make sure that the gateway has power (its Power LED is lit).
2. Connect an Ethernet cable to an Ethernet port on your computer
3. Connect the other end of the Ethernet cable to Ethernet port E2, E3, or E4 on the gateway.
.
Note: Do not use port E1 during setup.
Your computer connects to the local area network (LAN). A message might display on your computer page to notify you that an Ethernet cable is connected.
WiFi Connection
Y ou can connect to the gateway’ s WiFi network with Wi-Fi Protected Setup (WPS) or you can find and select the WiFi network. For information about using WPS, see WPS Overview on page 49.
To find and select the WiFi network:
1. Make sure that the gateway has power (its Power LED is lit).
2. On your computer or wireless device, find and select the WiFi network.
The WiFi network name is on the gateway’s label.
3. Join the WiFi network and enter the WiFi password.

Types of Logins

Separate types of logins have different purposes. It is important that you understand the difference so that you know which login to use when.
Types of logins:
• WiFi network key or password. Your gateway is preset with a unique wireless network
name (SSID) and password for wireless access.
Note: Your gateway broadcasts dual-band 2.4 GHz and 5 GHz WiFi signals.
The label shows the SSID for the 2.4 GHz signal. For information about 5 GHz WiFi settings, see Specify Basic WiFi Settings on page 41.
This information is on the gateway label.
• Gateway login.This logs you in to the gateway interface as admin from an Internet
browser

Log In to the Gateway

When you first set up your gateway, NETGEAR genie automatically starts when you launch an Internet browser on a computer that is connected to the gateway. If you want to view or change settings for the gateway, you can use genie again.

Port Forwarding Overview

Port forwarding allows you to forward incoming traffic from the outside network, to a range of WAN ports on an IP address on the LAN. You can also enable traffic from local network to a specified port range to be allowed to go outside of the network in medium firewall settings.
All the settings on this page are associated with a Service Profile in the Current Profile
drop-down list. If no profile has been created, the default profile is used. 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.
A typical application of port forwarding occurs when a remote computer
access a web server running on a computer in your local network. Using port forwarding, you can tell the gateway, “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.” sequence shows the effects of the port forwarding rule you have defined:

ADSL2+ Gateway
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 gateway. The remote computer composes a web page request message with the following destination information:
Destination address. The IP address www.example.com, which is the gateway’s address. 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
gateway.
2. Y
our gateway 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 gateway modifies the destination information in the request message:
The destination address is replaced with 192.168.1.123. Your gateway then sends this request message to your local network.
3. Y
our 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 the gateway a reply message.
4. Y
our gateway 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.
Port Forwarding to Permit External Host Communications
In both 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 gateway 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 browser needs to access a web server running on a computer in your local network. Using port forwarding, you can tell the gateway, “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
.example.com, which resolves to the public IP address of your gateway. The
www 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 gateway.
Destination port number. 80, which is the standard port number for a web server process.

To configure port forwarding, you need to know which inbound ports the application needs. T o find out, contact the publisher of the application or the relevant user groups or news groups.
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 page to configure the gateway 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. computer has to always have the same IP address.
Tip: T
o ensure that your server computer always has the same IP address,
use the reserved IP address feature of your product.

Set Up a Default DMZ Host

The default DMZ Host feature is helpful when you are using some online games and videoconferencing applications that are incompatible with Network Address Translation (NAT). The gateway is programmed to recognize some of these applications and to work correctly with them, but other applications might not function well. In some cases, one local computer can run the application correctly if the IP address for that computer is entered as the default DMZ server.
