6.6 NAT 1:1 Example

In this example, there is an SMTP mail server in the LAN zone. It has a private IP address of 192.168.1.21. The public IP address of the server is 1.1.1.1.

In order for the server to be accessible to people from the Internet (WAN zone), you need to create a 1:1 NAT mapping from the public IP address to its private one.
