N750 Wireless Dual Band Gigabit Router WNDR4000 User Manual

WAN Setup

Select Advanced > WAN Setup to display the following screen:

The following settings are available:

• Disable Port Scan and DoS Protection. The firewall protects your LAN against port

scans and denial of service (DoS) attacks. This protection should be disabled only in

special circumstances.

• Default DMZ Server. The default demilitarized zone (DMZ) server feature is helpful when

you use online games and video conferencing applications that are incompatible with

NAT. See Default DMZ Server on page 69.

• Respond to Ping on Internet WAN Port. If you want the wireless router to respond to a

ping from the Internet, select this check box. This should be used only as a diagnostic

tool, because it allows your wireless router to be discovered. Do not select this check box

unless you have a specific reason to do so.

• Disable IGMP Proxying. The IGMP Proxying function lets a PC on the LAN receive

multicast traffic from the Internet. Select this check box to disable the function if you do

not need it.

• MTU Size (in bytes). The normal Maximum Transmit Unit (MTU) value for most Ethernet

networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs you might

need to reduce the MTU. But this is rarely required, and should not be done unless you

are sure it is necessary for your ISP connection.

• NAT Filtering. By default NAT filtering is used.
