Hi Alan ,
The document says 
"/The default destination of a CoA packet is the NAS (or client)
#  the sent the original Access-Request or Accounting-Request./"

So in the Access-Request it is mentioned as shown in below

rad_recv: Access-Request packet from host port 57378, id=1,
    User-Name = "testing" 
    NAS-IP-Address = 
    NAS-Port = 4200 
    User-Password = "password" 

But then why it is showing "Unknown destination".  The log from the  radiusd
shows below.
Thu Apr  5 13:49:52 2012 : Info: WARNING: Unknown destination
for CoA request. 
Thu Apr  5 13:49:52 2012 : Info: Do CoA Fail handler here 

I have check with the netstat command in the OS  that a java program is
listening to the port 4200.

Do i have to configure the NAS client IP and port in home_server section of
originate-coa file ?

Thanks for your pa·tience
Best Reagards
