DMZ Host
The default DMZ (De-Militarized Zone) host feature is helpful when you are using some online games and
videoconferencing applications that are not compatible with NAT (Network Address Translation).
DMZ Host IP Address: The IP Address of the device for which the router’s firewall will be disabled. Be sure to assign a
static IP Address to that device. The DMZ host should be connected to a LAN port of the device. Be sure to assign a
static IP address to that DMZ host.
Warning!
DMZ servers pose a security risk. A computer designated as the DMZ server loses much of the protection of the firewall
and is exposed to exploits from the Internet.
UPnP
UPnP (Universal Plug and Play) allows Windows based systems to configure the device for various Internet applications
automatically. UPnP devices can automatically discover the services from other registered UPnP devices on the network.
If you use applications such as multiplayer gaming, peer-to-peer connections, or real-time communications, like instant
messaging or remote assistance (a feature in Windows XP), you should enable UPnP.
