Explanation

Palo Alto Networks firewalls evaluate NAT policies strictly from top to bottom, matching the first rule that fits the traffic. Unlike some other policy types, there is no prioritization by NAT type (Static, Dynamic IP, or Dynamic IP and Port). This means rule ordering is critical - more specific rules must be placed above more general ones to ensure correct matching. Administrators should design NAT rule order carefully to avoid unintended matches.
