No, the NAS does not go down, just either the router to the ISP or the ISP,
causing
a new IP address in a ISP DHCP environment

Yes, for the last 12 hours it works well. The Client-IP-Address changes when
the connection
to the ISP is down for whatever reason.
Here two packets were the ISP connection was down for 30 minutes (a moment),
while the NAS
was up and running, keeping the session alive. With the use of
Calling-Station-Id instead
of Client-IP-Address for acct_unique, the existing accounting table entry
will be used instead
of adding another entry for the same session (Acct-Unique-Session-Id remains
the same!):
