  Because you didn't follow the instructions.

  Er... no.  That's not how RADIUS works.  The Accounting-Response is
sent to the source port of the Accounting-Request packet.  You *cannot*
configure this, and you *cannot* change it.

  Did you read raddb/sites-available/originate-coa?  That question is
answered there.  Open it with a text editor, and look for "3799".

  And the warning comes about because you didn't follow the instructions
in that file.  Follow the instructions, and the warning will go away.
