cannot run Internet applications successfully from behind the router, then you can place the computer into the DMZ for unrestricted
Internet access.
Note:Putting a computer in the DMZ may expose that computer to a variety of security risks. Use of this option is only recommended
as a last resort.

ANTISPOOF CHECKING
This option allows you to manually congure the router’s demilitarized zone (DMZ). The
DMZ should only be used as a last resort when you are having diculty using other port
forwarding tools since the device using this IP address is not protected by the rewall. If
you use DMZ, take measures such as client-based virus protection to protect the remaining
client PCs on your LAN from possible attacks through DMZ’d device.
Enable DMZ: Check the box to enable the DMZ function.

Address:

Name dropdown menu and the << button to quickly select a device.
