View or Change the WAN Settings
You can view the wide area network (WAN) settings for the Internet port. You can set up a 
DMZ (demilitarized zone) server, change the maximum transmit unit (MTU) size, and enable 
the modem router to respond to a ping to its WAN (Internet) port.

iew or change the following settings:
•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, and many 
others. Select this check box only in special circumstances. 
• Default DMZ Server . 
 This feature is sometimes helpful when you are playing online 
games or videoconferencing, but it makes the firewall security less effective. See  Set 
Up a Default DMZ Server on page  51.
• Respond to Ping on Internet Port. 
 This feature allows your modem router to be 
discovered. Use this feature only as a diagnostic tool or for a specific\
 reason. 
• MTU Size (in bytes). 
 The normal MTU (maximum transmit unit) value for most 
Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Ch\
ange the 
MTU only if you are sure that it is necessary for your Internet connecti\
on. See Change 
the MTU Size on page  49.

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 uses a lower MTU 
setting than the other devices, the data packets must be 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 experience problems connecting to the Internet, and the technical support of either 
the Internet provider 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
•You use VPN and experience severe performance problems.
•You used a program to optimize MTU for performance reasons and now you are 
experiencing 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.
To change the MTU size:
1. Launch a web browser from a computer or wireless device that is connected to the 
network.
2. Type http://routerlogin.net.
A login window opens.
3. Enter the modem router user name and password.

5. In the MTU Size field, enter a value from 64 to 1500.
6.  Click the  Apply button.
Your change is saved.
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   
MTUApplication
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, adapte\
rs, 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 use 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.
