NATPAT and DMZ-DeMilitarized Zone

NATPAT and DMZ-De-Militarized Zone This lesson covers Network Access Translation and Port Address Translation. Network address translation (NAT) converts an internal IP address to an external IP address. The traffic is forwarded to the private IP and web servers. Port address translation tracks IP/Port numbers and a private IP is assigned to a public IP and port. The demilitarized zone (DMZ) creates an area for public use with a public facing firewall than is less restrictive then the private. It is the place for VPN concentrators and web servers.
