After setting up the router the first time, if you want to perform this task again, you can run

Setup Wizard from the Advanced tab of the NETGEAR genie.

1.

Select

Setup Wizard

to display the following screen:

2.

WPS Wizard

The WPS Wizard helps you add a WPS-capable client device (a wireless device or computer)

to your network. On the client device, you need to either press its WPS button or locate its

WPS PIN.

To use the WPS Wizard:

1.

Select

Advanced > WPS Wizard

.

2.

Click

Next

. The following screen lets you select the method for adding the WPS client (a

wireless device or computer).

You can use either the push button or PIN method.

3.

Select either

Push Button

or

PIN Number

.

•

To use the push button method, either click the

WPS

button on this screen, or press

the

WPS

button on the side of the router. Within 2 minutes, go to the wireless client

and press its

WPS

button to join the network without entering a password.

•

To use the PIN method, select the

PIN Number

radio button, enter the client security

PIN, and click

Next

.

Within 2 minutes, go to the client device and use its WPS software to join the network

without entering a password.

The router attempts to add the WPS-capable device. The WPS LED

on the front of

the router blinks green. When the router establishes a WPS connection, the LED is solid

green, and the router WPS screen displays a confirmation message.

4.

Repeat Step 2 and Step 3 to add another WPS client to your network.

WAN Setup

The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the

maximum transmit unit (MTU) size, and enable the router to respond to a ping on the WAN

(Internet) port. Select

Advanced > Setup > WAN Setup

.

•

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

, 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 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. You can select

this check box to disable the feature if you do not need 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. This 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

35.

•

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 allows almost all Internet applications to function.

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 router 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 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 discards incoming traffic from the Internet unless the traffic is a response to one of

your local computers or a service that you have configured in the Port Forwarding/Port

Triggering screen. Instead of discarding this traffic, you can have the router forward traffic to

one computer on your network. This computer is called the default DMZ server.



To set up a default DMZ server:

1.

On the WAN Setup screen, select the

Default DMZ Server

check box.

2.

Type the IP address.

3.

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 any device in the data path has a lower MTU

setting than the other devices, the data packets have to be split or “fragmented” to

accommodate the device with the smallest MTU.

The best MTU setting for NETGEAR equipment is often just the default value, and changing

the value might fix one problem but cause another. Leave 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

-

America Online’s DSL service
