I have used free radius for authentication purpose
Authentication for what? wireless AP?
When many internet users try to connect to isp router the free radius connected to the ppoe server should authenticate all the users in the client.
Meaning what, exactly? If you mean "check client's user/password, and if it's correct send access-accept", then that's what radius does, nothing special there.
What are the configuration changes need to be applied in the free radius.
Generally speaking, radius (ANY radius) doesn't really care what device acts as NAS. It can be wireless AP, pppoe/pptp server, BRAS, GGSN, whatever. If they can use the same authentication mechanism (e.g. PAP, MSCHAPv2, EAP-PEAP-MSCHAPv2) then the radius-side setup is the same no matter what the NAS is. -- Fajar
