Hi Ive got a micro ISP with 50 clients running on pppoe and freeradius for authenication, each client has a username and password. When a customer dials through his winbox to create pppoe connection the pppoe server on the server loads radius.so to do the authenication. What I want to do now is the following... I want to authenicate based on mac address and i do not want to use pppoe anymore..so everybody plugging in a network cable into my switch will have immediate internet access only if I have registered his mac address for him previously, otherwise everybody plugging his network cable into my swithces will have access to my internet connection. I mean I need something like the mac address filtering used in squid ...where only registered mac address are allowed through the proxy..any hints suggestions and/or tutorials are welcome. -- With Regards Ali Jawad
