Configuring the WAN Setup Options

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.

Description
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.
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,
Routes.
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.
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 it is necessary for your ISP connection. See
the MTU Size" on page 6-6.
