Creating a Virtual DMZ
A virtual DMZ (De-Militarized Zone) Host is a computer on your
network with reduced protection provided by the firewall. This
feature allows a single computer to be exposed to 2-way
communication from outside of your network. The PC is still
protected against DoS and hacker attacks.
CAUTION: 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, select
Redirect Request to Virtual DMZ Host and enter the IP address of
the computer in the IP Address of DMZ Host text box, and then
click SAVE.
Creating a Virtual Server Activating and configuring a virtual server allows one or more of
the computers on your network to function as an Internet service
host. For example, one of your computers could be configured as
an FTP host, allowing others outside of your office network to
download files of your choosing. Or, if you have created a Web
site, you can configure one of your computers as a Web server,
so that others can view your Web site.
If you are using One-to-Many NAT you can only have one server
of each type on your network. To have more than one server of
a type (for example more than one web server) visible to the
Internet you must be using One-to-One NAT.
To configure a virtual server:
1Click New on the right side of the screen to open the Virtual
Server Settings dialogue box. (Figure41)
2Enter the IP address of the computer in the Server IP Address text
box.
3Select the Service from the pull-down list. (Figure42)
