An example will help to illustrate how to set up a virtual server. If you wanted to use your computer as an FTP server, for instance, you would follow these steps.

1 Select an ID number that you want to associate with this computer—1, for example. (You can set up multiple virtual servers.)

2 The inbound and outbound port numbers for FTP are the same: 21. Enter 21 in the Public Port and Private Port fields.

3 Select the Port Type. For FTP, it is TCP, which is the default.

4 Click Add This Setting (in this case, there is no Save Changes button), and then click Write Settings to Flash and Reboot.

5 You need to enter the Host IP Address.

To obtain this address, navigate to the LAN Settings page by returning to the Advanced Setup page and clicking LAN. You’ll see the defined starting and ending IP address range; for example, 10.0.0.3 and 10.0.0.14. Your Host IP Address should be a static IP address outside of this range—say, 10.0.0.15.

To set this static IP address, go to Start Settings Network and Dial-up Connections. Right-click Local Area Connection, select Properties, highlight your NIC card’s TCP/IP entry and click Properties. Click the radio buttons Use the following IP address and Use the following DNS server addresses, enter the following data, and click OK.
