Hi Sid, we added proxy accounting in the "AAA Server => Proxy AAA" menu.
Further, the created proxy accounting profile is linked to a wifi network. The accounting messages will be send from the Controllers IP to the intended destination. But the NAS-IP RADIUS field indicates the IP of the AP. The captive portal now sends all client-related RADIUS requests to the AP IP directly. This is not possible in all cases (Router NAT).
It's like the controller acts like a distributor for the RADIUS packets but does not modify the contents.
