i have seen a lot of "ip nat inside source" commands, but no "ip nat outside source" or "ip nat inside destination", i know that "ip nat inside source" is used to make internal services available to the public. what are the other commands used for?

ip nat inside source - changes sources addrss of pkts from inside to outside. (or destination address of packets going from outside to inside)

ip nat outside source - changes destination address of pkts going from inside to outside. ( or source add of pkts going from outside to inside)

ip nat inside destination - Usually used in Round robin loadbalancing (TCP load balancing with NAT). Once you configure this command, it can used tochange the destinationa address of pkts coming from outside to inside, and map it on a round robin basis to one of the local private address.
