Currently, no command is available for querying the counts that packets match NAT Server.
No command is available for querying the counts that packets match the NAT address pool as well. However, you can query the matching counts of the NAT policy or ACL to determine the matching count of the NAT address pool.
For example:
If the following NAT policy is configured, then:
[USG-nat-policy-interzone-trust-untrust-outbound-0]display this
policy 0
action source-nat
address-group 2
Display the matching count of the NAT policy. The value is also the matching count of the NAT address pool.
[USG]display nat-policy interzone trust untrust outbound
nat-policy interzone trust untrust outbound
policy 0 (122 times matched)
action source-nat
policy service service-set ip
policy source any
policy destination any
address-group 2
