I have an ISE 2.1 installation in our lab. The wireless clients are connecting via an WLC with 8.3 code. I have created an MDM portal but cannot seem to get devices to pull the portal up. ACL is created on the controller and I see the url redirect in ISE when I check the users authentication. Everything seems fine.
When I launch a browser I don't get the portal. What troubleshooting steps do I take to figure out why the portal isn't displayed. There are iOS 10 devices (iPhone and iPads). Any tips would be greatly appreciated.
