I am using this command on the FR server in order to dicsconect the user on the NAS. The thing is that the NAS is using the same shared secret  for Authentication/Accounting/PoD/CoA and as you can see these messages are accepted and NAS also replyed back with Disconect-ACK. 
Is there another place where to configure the secret for PoD in FreeRadius?

  You really don't need '' around everything.

  So use the *correct* shared secret.

  It doesn't show the server receiving a Disconnect-Request?

  It doesn't show the shared secret for the client IP address?  You
can't use that shared secret in the "radclient" command above?
