ADVANCED
This page allows you to manually congure the router’s rewall & DMZ settings. Since some
applications are not compatible with NAT, the device supports the use of a DMZ IP address
for a single host on the LAN. This IP address is not protected by NAT and it is visible on the
Internet with the correct type of software. Note that any client PC in the DMZ is exposed
to various types of security risks. If you use DMZ, take measures (such as client-based virus
protection) to protect the remaining client PCs on your LAN from possible contamination
through DMZ.
Enable DMZ: Check to enable or disable DMZ functionality.
