64CHAPTER 5: GATEWAY CONFIGURATION

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.

Virtual Server

Activating and configuring a virtual server allows one or more of the computers on your network to function as a public server. For example, one of your computers could be configured as an FTP server, 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.

To configure a virtual server:

1Click New on the right side of the screen to open the Virtual Server Settings dialogue box. (Figure 46)

2Enter the last digit(s) of the IP address of the computer in the Server IP Address text box.

3Select the Service from the pull-down list. (Figure 46)
