Diagram of Incoming NAT
Incoming NAT allows you to specify ports on the private network that you would like to be available
on the public network. For example, if a web server is being hosted on a public network in Building
B (IP Address 10.0.0.3), you can create a pair that will specify that all requests on the public IP
address, Port 80, be forwarded to IP Address 10.0.0.3 on the private IP address, Port 80.
Inbound Port 80 request is re-addressed
to Private address 10.0.0.3. Then, it is
forwarded across the private network
