Explanation

NAT oversubscription controls how many sessions can share a single translated IP address and port combination beyond the default limit. This setting is a global session parameter and is found under Device > Setup > Session Settings > NAT Oversubscription Rate. It is not located under TCP Settings (option A), nor is it configured within individual NAT policy rules under the Policies menu (options B and C). Increasing this value allows the firewall to handle a larger number of concurrent NATed sessions per IP address.
