ipfw for udp on FreeBSD 12.1?

[Andreas X]

Dear Doug,

It was my bad! Indeed, I needed TCP, but thankfully at least I learned
allowing UDP too, by my question here.

Thank you all.

P.S: What are those "It is only some of the experimental accelerated file
transfer protocols that start playing with spraying UDP packets.", I'd love
to learn/read more about them, if they offer much faster transfer speed -
as FTP is terribly slow.. Always has been!

Regards.
