Hi, UoY provides eduroam availability at a number of NHS sites in the area who all use Cisco wireless controllers. I was just testing our new Grimsby connection ( remote controller pushes auth and accounting packets down a RADSEC tunnel to our Tier 1 eduroam servers) when I noticed that in addition to accounting packets relating to the eduroam SSID I was seeing accounting packets from other devices which had different NAS-IP-Address IP addresses to the one I was expecting. I know its their problem to fix but is there any way in FR 3.0.15 I can drop packets with a NAS IP Address != the one I should be seeing? We dump accounting / auth info into a postgres db and into our logstash service and I'd rather not have accounting info I shouldn't be seeing in there ... Rgds Alex
