What's the difference between "ip nat inside source list" and "ip nat inside source route-map"?

Hi experts,

My questions is just that. What's the difference between "ip nat inside source list" and "ip nat inside source route-map" and even when I shoud use one instead of the other??

Thanks a lot.

In simple terms:

ip nat inside source list   <-- specifies an access-list to define the traffic to be NAT'd.

ip nat inside source route-map   <--specifies a route-map to define the traffic to be NAT'd.

In older IOS versions, you couldn't use extended access-lists as the NAT source list so if you wanted to exclude NAT based on destination (for VPN for example), you had to use a route-map instead.  Within the route-map, you could specify an extended access-list.
