Hi All

We are having issues whereby users on the Guest ssid which use web auth with mac filter failure are able to access the internet without even authenticating.

It is on a 5508 WLC.

Any ideas why this is ?

cheers

Are you using ISE :

Make sure you have Setup preauth ACL allowing access to resources the user will need before L3 web authentication like dns, dhcp, radius server redirect page etc and deny everything else.
