I think you're a bit confused. FreeRadius does not run on the NAS. The 
NAS talks to FreeRadius.

Of course if the NAS is e.g. ChilliSpot then one could, in theory, run 
FreeRadius on the same Linux host, but they're conceptually different 
systems.

The answers is no. FreeRadius can't generate your accounting records for 
you. There are many ways you could do this:

  * script from cron e.g. shell script running radclient, python+pyrad
  * plugins on the NAS (what is your NAS?)
  * use non-radius accounting e.g. pmacct, softflowd
