To prevent impersonation, we need to match User-Id and Calling-Station-Id during authentication.
User-Id of the form 4371104 and Calling-Station-Id of the 234001014371104.
Please how do I achieve this?
You have given *no* details about how or why or where this is coming from but I'm guessing from your single example you are looking for: ---- /etc/freeradius/users ---- DEFAULT Calling-Station-Id !~ "[0-9]+%{User-Id}$", Auth-Type := Reject ---- This assumes: 1) User-Id is an attribute, I'm guessing you actually mean UserName 2) Calling-Station-Id is not something a user can influence (I can change the MAC address on my laptop to whatever I want) Cheers -- Alexander Clouter .sigmonster says: It don't mean a THING if you ain't got that SWING!!
