A DMZ can be used on a router in a home network. The DMZ router becomes a LAN, with computers and other devices connecting to it. Some home routers also have a DMZ host feature that allocates a device to operate outside the firewall and act as the DMZ. All other devices sit inside the firewall within the home network. A gaming console is often a good option to use as a DMZ host. It ensures the firewall does not affect gaming performance, and it is likely to contain less sensitive data than a laptop or PC.
