curl has no option to control what port number the data connection will open
and listen to for the PORT command.

This has two problems:
1) --local-port is the local end of all outgoing TCP connections. It is not
the port number to use when it expects the server to connect back.
2) --ftp-port tells the server to use the default, which in your case seems to
pick a private network one which just can't be right.

See, it set a local port from your selected port range.

192.168.* are private ones, so any external host will simply not be able to
reach you on that address.
Also, note that you have now published your user name and password to the
entire world, so I hope they were fakes or that you've already changed them.
