  It's hard, and often specific to a particular NAS.

  Newer NASes may support disconnect packets.  The upcoming 2.1.7 can
send disconnect packets, which will help.

  See the NAS documentation for how to disconnect users.  If it doesn't
say you can disconnect users... it likely can't be done.

  Maybe SNMP can be used to reset the port, but that may not always be
supported, either.

  Does the NAS documentation say it supports that attribute?

  No.  The billing software runs on a server, and not on the NAS.  It
can't control the NAS any more than FreeRADIUS can control the NAS.

  Buy a NAS that supports disconnect packets.
