From some time I observe that all access point at one of many our location cannot authenticate using radius.
Location has pppoe internet connection, MTU over vpn between AP and radius server is 1422. Framed-MTU parameter is set to 1000 at radius server.
tcpdump shows that Access Point creates udp even larger than local MTU of the network devices which is standard 1500, IP fragmentation occurs and as expected firewall drops it.

@michaszek I doubt if it is related to the UniFi APs. Can you check if the Radius Configuration is done correctly?
