[Wireless Router] DMZ introduction and set up

What is DMZ?

Virtual DMZ allows you to expose one computer to the Internet, so that all the inbounds packets will be redirected to the computer you set. It is useful while you run some applications that use uncertained incoming ports. Please use it carefully.

Special Applications: Some applications require special handler against NAT. These special handlers are disabled in default.

Note: Opening all the ports on a PC to the Internet makes the network vulnerable to outside attacks.  Please be aware of the security risks involved in using DMZ.

Set up DMZ through the ASUS router web GUI

   (1). Connect your computer to the router via wired or WiFi connection and enter your router LAN IP or router URL http://www.asusrouter.com to the WEB GUI.

   (2). Key in your router's username and password to log in.

Note: If you forget the user name and/or password, please restore the router to the factory default status and setup.
