Go to Forwarding Virtual servers in the menu, in order to visualize and add virtual servers,
as shown in the following screen (Figure 8-2). Virtual servers can be used for setting up pub-
lic services on your LAN, such as DNS, Email and FTP. A virtual server is defined as a service

specified by the server IP. Any PC that was used for a virtual server must have a static or
reserved IP Address because its IP Address may be changed when using the DHCP function.
