I can't find much on this
I can easily auth with an external freeradius server. But what about bandwidth control and quota?
WISPr-Bandwidth-Max-Up seems to work but what about quota?
I am interested in this topic as well. I want to be be able to use accounting with the captive portal and not finding much in the docs.
I reverted too pfsense as it has docs on this and the radius dictionary file and quota control attribute
Its currently not implemented, sorry.
