Captive Portal Radius Access-Request missing Calling-Station-ID

[Juergen]

Hi Team!

I would like to use the captive portal of OPNsense 20.1 and manged to configure it all right. So far everything is working but my radius-server (HP-MSM Controller) is dropping the access-requests because of missing the calling-station-id. I reviewed the packages with wireshark and there is no calling-station-id or called-station-id. Also the NAS-Identifier is some strange number.
Is there a way to set or populate this fields? As I understand most radius servers need this values to make some intelligent access-rules.

Thanks!
