Set Up a Default DMZ Server

WARNING:
For security reasons, you should avoid using the default DMZ
server feature. When a computer is designated as the default DMZ
server, it loses much of the protection of the firewall and is
exposed to many exploits from the Internet. If compromised, the
computer can be used to attack your network.
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with NAT. The router is programmed to
recognize some of these applications and to work correctly with them, but there are other
applications that 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.
Incoming traffic from the Internet is normally discarded by the router 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 it
forwarded to one computer on your network. This computer is called the default DMZ server.

Description
This check box is cleared so that the firewall protects your LAN
against port scans and denial of service attacks. This check box
should be selected only in special circumstances.
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
Default DMZ Server
If you want the router to respond to a ping from the Internet, select
this check box. This setting should be used only as a diagnostic tool,
since it allows your router to be discovered. Do not select this check
box unless you have a specific reason to do so.
Maximum transmit unit (MTU) value. For most Ethernet networks this
setting is 1500 bytes, or 1492 bytes for PPPoE connections, or 1436
bytes for PPTP connections.
This parameter is set to Secured to provide a secure firewall to
protect computers on the LAN from attacks from the Internet. The
Open setting is less secure.
Some VoIP applications do not work well with SIP ALG. Selecting
this check box might help your VoIP devices create or accept a call
through the router.
