Customizing Your Network Settings

5-7

The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the 
Maximum Transmit Unit (MTU) size, and enable the wireless router to respond to a ping on the 
WAN (Internet) port. From the main menu, under Advanced, click WAN Setup to view the WAN 
Setup screen.  

The WAN Setup fields are described in the following table:

Disable SPI Firewall

The Stateful Packet Inspection (SPI) firewall protects your network and 
computers against attacks and intrusions. A stateful packet firewall carefully 
inspects incoming traffic packets, looking for known exploits such as 
malformed, oversized, or out-of-sequence packets. The firewall should be 
disabled only in special circumstances, such as when you are troubleshooting 
application issues. 

Default DMZ Server

This feature is sometimes helpful when you are using some online games and 
videoconferencing. Be careful when using this feature because it makes the 
firewall security less effective. See the following section, 

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, since it allows 
your wireless router to be discovered. Do not select this check box unless you 
have a specific reason to do so.
