  That's how RADIUS works.

  FreeRADIUS doesn't work like that.

  It is *your* responsibility to track these duplicate requests.  That's
why FreeRADIUS has modules like "SQL".  They track these duplicate requests.

  FreeRADIUS does not include a long-term database to track accounting
packets.  It will *never* have such an internal database.  That's what
SQL is for.  The SQL server does database things, FreeRADIUS does RADIUS
things.
