  Then either the reply is coming from an IP that the NAS doesn't
like, or the shared secret is wrong.

  Once you get the NAS to accept the response from the server, the
duplicate entries in will disappear, and accounting will start.

  I suggest using 'tcpdump' on the network to see what's going on with
the RADIUS packets.  Look at src/dst IP's...
