DMZ hosting forwards all the ports at the same time to one PC. The Port Range Forwarding is more secure because it only opens the ports you want to have opened, while DMZ hosting opens all the ports of one computer, exposing the computer to the Internet. Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static IP address assigned to it because its IP address may change when using the DHCP function. STEP 1 Click Network Setup on the tab and then click DMZ in the navigation pane. The DMZ window opens. STEP 1 Click Network Setup > DMZ. The DMZ window opens.
