  The NAS is probably sending the same NAS-Port number in all accounting
packets.

  Run the server in debugging mode to see what's going on.  But I
suspect that the NAS isn't doing the right thing.

  You're probably better off using SQL for accounting data.  It will log
everything sent by the NAS.  The radutmp file is meant to store only
utmp information.  So things like Acct-Session-Id and MAC address just
don't fit in the file.
