Virtual DMZ
Figure 46 Virtual Servers Screen
DMZ (De-Militarized Zone) Host is a computer without the protection of
the firewall. This feature allows a single computer to be exposed to
unrestricted 2-way communication from outside of your network. This
feature should be used only if the Virtual Server or Special Applications
options do not provide the level of access needed for certain applications.
To configure one of your computers as a DMZ host, enter the last digit(s)
of the IP address of the computer in the IP Address of DMZ Host text box,
and then click Apply.
