We are using Captive Portal authentication on our Public Wifi. We have blacklisted several devices. Prior to doing so, I adjusted the blacklist timeout on the virtual AP from 3600 to 0 so they would be permanently blacklisted. For the most part, this is working quite well, however there are about 5 devices that are not staying blacklisted--when I look at the blacklisted clients, either within the CLI or the GUI, it shows those few devices as counting down the number of minutes until they will be re-enabled. It is the same few MAC addresses, one is an iPod, and the rest are iPhones. Other iPods and iPhones have been blacklisted permanently successfully. I have tried both blacklisting them while connected, through the GUI, as well as when they are not connected, using the command line. I have not done a user-debug, since it's only been after they were blacklisted that I noticed this behavior.
Any ideas as to why these few wouldn't be behaving as expected? Please advise. Thanks!
