Chapter 7 Network Address Translation (NAT) Screens
P-663HN-51 User’s Guide
90
The following table describes the labels in this screen.
7.6 DMZ Host
In addition to the virtual servers for specified services, NAT supports a DMZ host
IP address. The DMZ host receives packets from ports that are not specified in the
applications in the virtual server configuration.
Note: If you do not assign a DMZ host IP address, the ZyXEL Device discards all
packets received for ports that are not specified here or in the remote
management setup.
