used by this NAT translation session.
Rule ID The ID of the NAT rule invoked.

invoked (from the rule definition).
Protocol The IP protocol used by the data packets that are
undergoing translations (from the rule definition)
Example: TCP, UDP, ICMP.
Alg Type The Application Level Gateway (ALG), if any, that
was used to enable this NAT translation (ALGs are
special settings that certain applications require in
order to work while NAT is enabled).
NAT Direction The direction (Inside or Outside) of the translation. A
NAT direction is assigned to each interface; the
Ethernet and USB interfaces are defined as inside,
and the WAN interfaces are defined as outside. The
