PfSense + CaptivePortal + FreeRADIUS

[ypc]

Hi,

I have a PfSense Environment using CaptivePortal and FreeRadius for authentication process. We need to make validation by username, IP Address and MAC address, but CaptivePortal don't send the Calling-Station-Id parameter, only send Called-Station-Id with the same IP address as value in all cases, seems to be the Gateway Interface MAC address.

How can I get the MAC address in Calling-Station-Id parameter on the Radius packages received by the FreeRADIUS server???
