Port Forwarding NAT (NAPT) Operation
The following figure describes an example of Port Forwarding used for security, hiding the private IP address
from the public interface network and it can be used to preserve private IP address even if public IP network
subnet might change, reducing operational risk and expense. In this example, Port Forwarding NAT is
configured at the Base Station in AGRM mode including the user configuration of NAT Address Map Table and
expected session table (a detailed in / outbound session is shown for clarity of explanation, where NAT
session table in SuperVisor will show a session in one line which will include inbound / outbound transactions,
session duration, statistics, etc).
