NAT confusion

On this image, I wanted to point out each of the NAT addresses to see if I am correct on this, and confused on the last portion.

Inside Global - 22.23.24.25
Outside Global - 15.16.17.18
Inside Local - 192.168.1.22
Outside Local - ??


I understand the definition of the above, just having issues applying it.

Inside Global - Local host, external address
Outside Global - External host, external address
Inside Local - Local host, internal address
Outside Local - External host, internal address

You have the first 3 right, so the 4th should be obvious

Inside Global > Your IP address as seen by the public.
Inside Local > Your local IP address not seen by the public.
Outside Global > The public IP of your destination.
Outside Local > The inside IP of your destination (normally unused).
