Description:
In this deployment environment, we make up a private IP network of 192.168.100.100. NAT function is enabled to
support multiple clients to access Internet.
In this example, the ADSL Router acts as NAT device which translate a private IP address into a public address.
Therefore multiple users can share with one public IP address to access Internet through this router. The public
address can be a static public address that is pre-assigned by ISP or a dynamic public address that is assigned by ISP
DHCP server.
