2.6 DMZ

In certain instances, you may want to give one computer on your LAN unrestricted Internet access. For example, you may want to use an application such as NetMeeting that uses dynamic ports. Or you may want to use the computer to play games over the Internet, and you want others to be able to initiate games with you. Without a DMZ, you would always have to be the one to initiate a game. A DMZ configuration allows the computer to accept all incoming packets that it has solicited.

CAUTION! Use the DMZ feature with the utmost care. It exposes the DMZ computer’s entire contents to the Internet; there is no firewall protection whatsoever.

To enable the X4’s DMZ feature, follow these steps.

From the Advanced Setup page, click the DMZ button.

Select Enable from the DMZ dropdown list, then click Save Changes and Write Settings to Flash and Reboot.

You need to enter the DMZ Host IP address. To obtain this address, navigate to the LAN Settings page by returning to the Advanced Setup page and clicking the LAN Settings button. You’ll see the defined starting and ending IP address range; for example, 10.0.0.3 and 10.0.0.14. Your DMZ Host IP Address should be a static IP address outside of this range— say, 10.0.0.15.
