Virtual Servers Figure 41 Virtual Servers Screen

This function will allow you to route external (Internet) calls for services such as a web server (port 80), FTP server (Port 21), or other applications through your Router to your internal network. Since your internal computers are protected by a firewall, machines from the Internet cannot get to them because they cannot be 'seen'.

If you need to configure the Virtual Server function for a specific application, you will need to contact the application vendor to find out which port settings you need.

To manually enter settings:

1Enter the IP address in the space provided for the internal machine.

2Enter the port type (TCP, UDP, or both TCP and UDP).

3Specify the Public port that will be seen by clients on the Internet, and the LAN port which the traffic will be routed to.

4You can enable or disable each Virtual Server entry by checking or unchecking the appropriate Enable checkbox.

5Click Apply to save the changes for each Virtual Server entry.
