DMZ The DMZ hosting feature allows one local user to be exposed to the Internet for use of a
special-purpose service such as Internet gaming or videoconferencing. DMZ hosting forwards all
the ports at the same time to one PC. The Port Forwarding feature 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 so the Internet can see it.
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.
1. To expose one PC, select Enable.
2. Enter the computer's IP address in the DMZ Host IP Address field.
3. Click the Apply button.
Block WAN Request
By enabling the Block WAN Request feature, you can prevent your network
from being “pinged,” or detected, by other Internet users. The Block WAN Request feature also
reinforces your network security by hiding your network ports. Both functions of the Block WAN
Request feature make it more difficult for outside users to work their way into your network. This
feature is enabled by default. Select Disable to disable this feature.
