ADVANCED - DMZ

Since some applications are not compatible with NAT, the Router supports use of a DMZ IP address

for a single host on the LAN. This IP address is not protected by NAT and will therefore be visible to

agents on the Internet with the right type of software. Keep in mind that any client PC in the DMZ

will be exposed to various types of security risks. If you use the DMZ, take measures (such as client-

based virus protection) to protect the remaining client PCs on your LAN from possible contamination

through the DMZ.

DMZ window

To designate a DMZ IP address, select the

Enabled

radio button, type in the

IP Address

of the server

or device on your LAN, and click the

Apply

button. To remove DMZ status from the designated IP

address, select the Disabled radio button and click

Apply

. It will be necessary to save the settings

and reboot the Router before the DMZ is activated.
