address to each of the ProxyServer’s WAN ports and then map your servers to that WAN port
address the same way you would map a static IP address from your ISP. The predefined Global
Dynamic WAN port addressing scheme is 0.0.0.1 for WAN port 1, address 0.0.0.2 for WAN port 2,
and 0.0.0.3 for WAN port 3. If MLPPP is being used, you can assign 0.0.0.0 to all three WAN ports.
You can dynamically map any one Global Dynamic address to any WAN port on the ProxyServer and
statically map the other two ports, or you can statically map all three WAN ports.

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
