addresses the same way you would map a static IP address from your ISP. The predefined Dynamic
WAN port addressing scheme is 0.0.0.1 for WAN port 1 and address 0.0.0.2 for WAN port 2. If
MLPPP is being used, you can assign 0.0.0.0 to both WAN ports. You can dynamically map one
Global Dynamic address to either WAN port on the ProxyServer and statically map the other WAN
port.

Figure 4-5. Application Showing Servers Connected to One Global IP Address
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 is added
to the Global IP Addresses group in the Virtual Server setup dialog box. This could also be a Global
Dynamic WAN address.
