The ip nat source inside is the one commonly used since you are translating
your internal network to the outside while the ip nat source outside you are
translating the outside network to match your internal routing domain.
For instance, you want your local servers to connect to google.com
by using 192.168.1.100 instead of 209.85.165.147
I'm sure there are other reasons for using ip nat outside, but that's just
one example.
