to Alex M:<br>&gt;If u are using MySQL you need to set, radiusd.config<br>&gt;to read NAS table im MuSQL (look et the end of the config file, I &gt;think it's a last line) and then add your NAS clients to NAS table im &gt;db&nbsp;&nbsp;&nbsp; 
<br>Thanks for your advice. Will you please explain and describe the detail to me ? I searched through the radiusd.conf and couldn't locate the entry for nas. And my NAS table in 'freeradius' database looks like the following:
<br>mysql&gt; select * from nas;<br>+----+------------------------+---------------+---------+----------+---------------+-----------------+------------------+<br>| id&nbsp;&nbsp; | nasname&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; |shortname&nbsp; | type&nbsp;&nbsp; | ports&nbsp;&nbsp; | secret&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; | community | description&nbsp;&nbsp; |
