Who Me Too'd this solution

Hello Tician,

Here are some of the useful commands for NAT troubleshooting ( "nat-inside-2-outside" is the rule used for reference):

> show running nat-policy                    // Show currently deployed NAT policy

> show running nat-rule-cache               // Show all NAT rules of all versions in cache

> show running nat-rule-ippool rule nat-inside-2-outside       // NAT rule ippool usage

> debug dataplane nat sync-ippool rule nat-inside-2-outside          // To kill sessions pertaining to a particular NAT rule and re-sync the ippool

>> For a particular session, the NAT translation can be viewed as:

admin@88-PA-VM-300> show session all filter application ping
