Explanation:
BD
All packets processed by the ASA are evaluated against the NAT table. This evaluation starts at the top
(Section 1) and works down until a NAT rule is matched. Once a NAT rule is matched, that NAT rule is applied
to the connection and no more NAT policies are checked against the packet.
+ Section 1 – Manual NAT policies: These are processed in the order in which they appear in the configuration.
+ Section 2 – Auto NAT policies: These are processed based on the NAT type (static or dynamic) and the prefix
(subnet mask) length in the object.
+ Section 3 – After-auto manual NAT policies: These are processed in the order in which they appear in the
configuration.
