Hi,
You dont really have any need to add the configuration
global (outside) 1 200.200.200.1
Since you already have
global (outside) 1 interface
And they are the same
global (outside) 1 interface = global (outside) 200.200.200.1
I am not sure what you want to do here since you are trying to add a configuration command that you actually have already on the device.
If you want to add more source network under the same Dynamic PAT then you can use the format
nat () 1
Where you naturally replace the
= with the "nameif" of the interface where the source network resides
= with the source networks network address
= with the network mask of the source network being added
Hope this helps
