 Hi,
 if needed, have u changed or added the new client to radius?

 Andreas,
  
 Thanks for your reply.
  
 Client of of the radius was set to 0.0.0.0, which means any NAS.
  
 The freeradius server received the request and the reply was sent to the WIFI router as well. 
  
 The problem is packet was drop by private network gateway. Since the authentication request is in UDP. The private network gateway doesn't have a session opened for the NAS.
  
 Thanks!
  
 Tom
