Command	Description
clear ip nat translations { * [ inside [ tcp { inside [ global-ip [ global-port ] local-ip [ local-port ]} udp { inside [ global-ip [ global-port ] local-ip [ local-port ]}] [ inside global-ip local-ip ][ outside local-ip global-ip ]	Clears dynamic entries from the NAT table.

ip nat outside source { list { access-list-numbername } pool name static global-ip local-ip }	Enables translation of outside source addresses.
ip nat pool name start-ip end-ip { netmask netmask prefix-length prefix-length } type { rotary match-host }	Defines a pool of addresses to be used for address translation.
ip nat translation max-entries entries	Sets a limit on the number of entries allowed in the NAT table.
ip nat translation { timeout udp-timeout dns-timeout tcp-timeout finrst-timeout icmp-timeout syn-timeout port-timeout { tcp udp }} seconds	Changes the default period after which a dynamic entry is removed from the NAT table and the address is returned to the pool.
