The show ip nat inside rule and show ip nat outside rule commands display access list and pool usage for all dynamic translation rules configured for the virtual router. If you do not specify an access list, the output displays address pool associations for each of the access lists for either inside or outside translation rules in the virtual router. Specifying an access list filters the output to display only the address pool associated with the specified list.
