DMZ
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 to agents 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 the DMZ, take
measures (such as client-based virus protection) to protect
the remaining client PCs on your LAN from possible
contamination through DMZ.
