What is a DMZ and how to configure DMZ host

What is a DMZ
A DMZ (demilitarized zone) on a home router refers to a DMZ Host. Strictly speaking, this is not a true DMZ. A home router DMZ host is a host on the internal network that has all UDP and TCP ports open and exposed, except those ports otherwise forwarded. Which is often used a simple method to forward all ports to another firewall/NAT device.
