You may want to place one of your computers behind the firewall temporarily outside the firewall for troubleshooting purposes. Keeping a computer outside the firewall is not good practice except temporarily for troubleshooting.
In order to do this you need access to your router's IP Address. In most home computers connected to the Internet via a router, this address is http://192.168.0.1.
On my Arris router supplied by Oceanic Time Warner, I can go to the DMZ page directly by entering the router address as shown:

Of course you need the username and password, which you can get from the service provider.
All you need to do is indicate which of the Internal computers behind the firewall goes to the DMZ. The settings of DMZ will have both a Public IP (WAN IP) as well as an Internal (Private IP). Note that all the ports on the computer in the DMZ can be attacked by hackers.
