DMZ Host
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.
To designate a DMZ IP address, type in the IP Address of the server or
device on your LAN, and click the
Save/Apply
button.
