Some online games and videoconferencing applications are incompatible with NAT. The MR814
v3 router is programmed to recognize some of these applications and to work properly with them,
but there are other applications that may not function well. In some cases, one local PC can run the
application properly if that PC’s IP address is entered as the default in the PORTS Menu. If one
local PC acts as a game or videoconferencing host, enter its IP address as the default.
Configuring the WAN Setup Options
The WAN Setup options let you configure a DMZ server, change the MTU size and enable the
router to respond to a Ping on the WAN port. These options are discussed below.
Setting Up a Default DMZ Server
The default DMZ server feature is helpful when 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 properly with them, but there are other applications that may not function
well. In some cases, one local PC can run the application properly if that PC’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 Ports menu.
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This
computer is called the Default DMZ Server.
Note: DMZ servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall, and is exposed to exploits from the
Internet. If compromised, the DMZ server can be used to attack your network.
