These are _source_ ports.

These are _destination_ ports.
Source and destination ports are entirely different concepts. Source
port number is just "socket ID" (randomly) selected by OS. Destination
port is more important thing because TCP/UDP servers listen for
incoming requests on specified destination ports.
Don't worry about NAT in this case.
