I am having the exact same issue. Can anybody assist with this issue. "anybody can connect a device on my network and the Freeradius server reply to DHCP Discover, assign an IP address using the mysql radipool table but without checking if the mac address is in the radcheck table."

Haven't looked at this directly, but it should be pretty easy. I'm guessing you want to either copy DHCP-Client-Hardware-Address into Calling-Station-Id, then call sql (with Calling-Station-Id in the radcheck table), or just all DHCP-Client-Hardware-Address directly into the radcheck table, then just call sql.

Based on the result code from sql, you probably then want to update the DHCP-Message-Type to inhibit a reply if the MAC wasn't found.

Hello I successed to install and configure MAC Authentication ans DHCP pool. But at this point, I have done to many thing to explain how we can implement this solution. I hope I will reinstall it the next week and I will give you the solution. But the solution works :) Best Regards Thomas
