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 in One-to-Many

NAT mode. 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 specify 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:

1 Click New on the right side of the Virtual Servers screen to open

the Virtual Server Settings dialogue box. (Figure 45

2 Enter the IP address of the computer in the Server IP Address text

box.

3 Select the Service from the pull-down list.

Figure 45 Virtual Servers Settings Screen

If you select Custom, the screen shown in Figure 46 displays.

Specify a suitable name for the service and then enter the port

numbers required for that service. If a service requires more than

one port number enter the multiple ports as a comma separated

list or a range e.g. 51,52,54-59.
