The Virtual Server Setup dialog box defines how the servers are connected to the one global IP
address. The static IP address that we established in our virtual server connection example above is
added to the Global IP Addresses group in the Virtual Server setup dialog box. This could also be a
Global Dynamic WAN address.
With static IP addressing, the Global Ip Address is the IP address that is seen by the Internet. This
global address will be used by the virtual server feature to filter the activity of the traffic to and from
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.
