Diagram of Incoming NAT
Figure 5-4: Incoming NAT
Incoming NAT allows you to specify ports on the private network (Building B) that you
would like to be available on the public network (Building A and the Internet). For
example, if a web server (IP Address 10.0.0.3) is being hosted on a private network in
Building B, 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
