Manage WPS Settings
You can control how WPS functions on the modem router. Use caution if you\
 change the 
WPS settings.
Note: For information about how to use WPS to add WiFi devices and other 
equipment to your WiFi network, see Join the WiFi Network of the 
Modem Router  on page  21 and  Use the WPS Wizard to Add a Device 
to the WiFi Network on page  45.
To specify WPS settings:
1. Launch an Internet browser from a computer or WiFi device that is connec\
ted to the 
network. 
2.  T
ype  http://www.routerlogin.net .
A login window opens.
3.  T
ype  admin for the user name and type your password.
If you did not yet personalize your password, type  password for the password.
4.  Click the  OK button. 
The BASIC Home page displays.
5.  Select  ADV
 ANCED > Advanced Setup > Wireless Settings .
The Wireless Settings page displays.
6.  Scroll down to the WSP Settings section.
The  Gateway’s PIN field displays the PIN that you can enter on a registrar (for example,\
 
Windows Connect Now in Microsoft Windows 7) to configure the modem rout\
er’s WiFi 
settings through WPS.
7.  Specify the WPS settings:
• Disable Gateway’
 s PIN. By default, the PIN is enabled, but situations might occur in 
which you want to disable the PIN. The PIN function might temporarily be disabled 
when the modem router detects suspicious attempts to break into the mode\
m router’s 
WiFi settings through use of the modem router’s PIN and WPS. You can manually 
disable the PIN function by selecting the Disable Router’s PIN check box.

•Keep Existing Wireless Settings. By default, the Keep Existing Wireless Settings 
check boxes are selected for the 2.4 GHz and 5 GHz bands.
NETGEAR recommends that you leave these check boxes selected. However, when 
these check boxes are selected, some applications might not detect the modem 
router.
CAUTION:
When you clear a Keep Existing Wireless Settings check box and you 
add a new WiFi client through WPS, the modem router’s WiFi settings for 
the associated network change to an automatically generated SSID and 
passphrase (also referred to as the WiFi network password or network 
key).
8. Click the Apply button.
Your settings are saved.
Manage the Advanced WiFi Features
The modem router supports the following advanced WiFi features:
•WMM. Wi-Fi Multimedia Quality of Service (WMM QoS) prioritizes WiFi voice and video 
traffic over the WiFi link. 
WMM QoS prioritizes WiFi 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, WMM must be enabled on both the application and the client 
running that application. 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. This feature is enabled by default, but you can disable it.
•PMF. Protected Management Frames (PMF) is a security feature that protects unicast 
and multicast management frames from being intercepted and changed for malicious 
purposes. This feature is disabled by default, but you can enable it.
PMF is supported in Windows 8. If all computers on your network run Windows 8, you can 
enable PMF. If you are not sure, keep PMF disabled.
•WMF. Wireless Multicast Forwarding (WMF) lets the modem router forward multicast 
frames to wireless LAN (WLAN) hosts, using unicast addresses. WMF provides robust 
wireless communication because unicast frames are acknowledged, retried, and 
dynamically rate-controlled. This feature is enabled by default, but you can disable it.
•AT F. Airtime Fairness (ATF) ensures that all WiFi clients receive equal time on the 
network. Network resources are divided by time, so if five WiFi clients are connected to 
the network, they each get one-fifth of the network time. The advantage of this feature is 
that the slowest WiFi clients do not control network responsiveness. This feature is 
disabled by default, but you can enable it.

12.   Manage Port Forwarding and Port 
Triggering
You can use outbound firewall rules, port forwarding, and port triggering to set up rules for 
Internet traffic for services and applications. You need networking knowledge to set up these 
features.
This chapter includes the following sections:
•Manage Port Forwarding to a Local Server for Services, Applications, and Games
•Manage Port Triggering for Services, Applications, and Games

Manage Port Forwarding to a Local Server for Services, 
Applications, and Games
If a server is part of your network, you can allow certain types of incoming traffic to reach the 
server. For example, you might want to make a local web server, FTP server, or game server 
visible and available to the Internet.
The modem router can forward incoming traffic with specific protocols to computers on your 
local network. You can specify the servers for applications and you can also specify a default 
DMZ server to which the modem router forwards all other incoming protocols (see 
Set Up a 
Default DMZ Server on page 82).
Forward Incoming Traffic for a Default Service or Application
You can forward traffic for a default service or application to a computer on your network.
To forward incoming traffic for a default service or application:
1. Decide which type of service, application, or game you want to provide.
2. Find the local IP address of the computer on your network that will provide the service.
The server computer must always receive the same IP address. To specify this setting, 
use the reserved IP address feature. See 
Manage IP Address Reservation on page 85.
3. Launch an Internet browser from a computer or WiFi device that is connected to the 
network.
4. Type http://www.routerlogin.net.
A login window opens.
5. Type admin for the user name and type your password.
If you did not yet personalize your password, type password for the password.
6. Click the OK button.

Make sure that the  Port Forwarding radio button is selected.
9.  From the Service Name  menu, select the service or application.
If the service or application that you want to add is not in the menu, c\
reate a port 
forwarding rule with a custom service or application (see  Add a Port Forwarding Rule with 
a Custom Service or Application on page  167).
10.  In the Server IP 
 Address field, enter the IP address of the computer that must provide the 
service or that runs the application.
11.  Click the  Add button.
Your settings are saved. The rule is added to the table on the Port Forwarding / Port 
T
 riggering page.
Add a Port Forwarding Rule with a Custom Service or 
Application
The modem router lists default services and applications that you can us\
e in port forwarding rules. If the service or application is not predefined, you can add a po\
rt forwarding rule with a 
custom service or application.
To add a port forwarding rule with a custom service or application:
1.  Find out which port number or range of numbers the service or applicatio\
n uses.
You can usually find this information by contacting the publisher of the \
service or  application or through user groups or news groups.
2.  Launch an Internet browser from a computer or WiFi device that is connec\
ted to the 
network.
