This article describes the DMZ Host feature for the Datto Networking Appliance (DNA).
In networking, a demilitarized zone or perimeter network (often referred to as a DMZ) functions as a container subnetwork to selectively expose a network's external-facing services to the Internet, while keeping the remainder of the network firewalled, adding a layer of protecting to a LAN. For more information about DMZ technology, see DMZ (computing).
To access the DMZ Host card, log into the DNA web interface, and click Security, as shown in Figure 1.
