the Internet by functionality. The addresses that we assigned to our servers in the virtual server
example are unregistered addresses that are only seen by the ProxyServer. These local IP
addresses are arbitrarily assigned to servers in our virtual server connection example. For example,
we assigned IP address of 192.168.11.20 to the FTP server, 192.168.11.30 to the Web server,
192.168.11.40 to the e-mail server, and 192.168.11.50 to the MultiVOIP.
These local addresses are then mapped to the global address by function. The FTP server was
assigned an IP address of 192.168.11.20 with a TCP and UDP protocol and a port number of 20 and
21. The Mapping Details [Local] group in the Virtual Server Mappings dialog contains the FTP
server local mapping information. When the FTP server mapping information is entered, the Web
server can be mapped to the global address by entering the IP address 192.168.11.30 in the Local IP
Address field of the Mapping Details [Local] group with its protocol and port information. Then the
mail server, and if a MultiVOIP is used in the local network - its mapping information, can be added to
the local mapping group.
The Virtual Server Setup dialog displays all the local mapping information.
