to Alex M:
If u are using MySQL you need to set, radiusd.config to read NAS table im MuSQL (look et the end of the config file, I >think it's a last line) and then add your NAS clients to NAS table im >db 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: mysql> select * from nas; +----+------------------------+---------------+---------+----------+---------------+-----------------+------------------+ | id | nasname |shortname | type | ports | secret | community | description | +-----+-----------------------+---------------+---------+----------+---------------+-----------------+-------------------+ | 1 | 202.117.15.164 | liv1 | other | NULL | testing123 | NULL | RADIUS Client
