  You don't need a Session-Timeout.  You *do* need a NAS which works.

  No... that's not Access-Accept.  If you're running in debugging mode,
you'll see Access-Accept, followed by a series of attributes.  It should

  Look for the IP address.  If the NAS is sending accounting packets,
the IP will show up in the logs.
