Hi everybody!! Im using freeradius in a simple way (freeradius + MySQL). I have some users attached to some groups... it works fine!! The groups have some simple attributes like "Max-All-Session" in radgroupcheck table. Now I need to limit the users to some MAC Address. I mean, I have the User "AAAA" and I need use it only with these MAC Address: 00:23:8B:7F:47:DD 00:23:8B:7F:AA:BB 00:23:8B:7F:CC:EE I'm using the atributte Calling-Station-Id in the radcheck table, like this: AAAA Calling-Station-Id == 00:23:8B:7F:47:DD It works fine, but just for only one MAC address, If I put 2 or more MAC address It doesnt work. What can I do in order to enable some MAC Address attached to users in mysql database? (not only one?) Thanks !! -- * **Andres Gomez*
