I have a requirement to setup a Captive Portal that will log user in and then further limit the total bandwidth consumed by each User in a given amount of time.
Is there a RADIUS attribute that OpnSense can consume to implement this? I will be using a FreeRADIUS backend (either the OpnSense plugin, or a separate service). I'm open to use any other backend that can implement this easily with OpnSense.

Thank you
