iControl SNAT Pool list vs Web interface

The LocalLBSNATPool.get_list() should return the full list. The only thing I can think of is that iControl by default only queries the objects in the current folder. You can override that by setting the recursive query state flag with the System.Session.set_recursive_query_state() method. I highlighted that in my article on iControl folders

I'll do some testing and see if I can recreate your issue.
