I've spent ages with customers before trying to bypass Apple's CNA but today I am with a customer who wants the CNA to pop up and I cant get it to happen!
All captive portal is set up, bypass CNA is off in the CP Profile as well as in Clearpass. There are no additional allows in the firewall except to CPPM and also one to allow access to CPPM via an external link (this is required by the set up here due to the way the guest VLAN is protected from the internal network). There is no Apple whitelisting at all.
Android and Windows devices all work correctly with their respective popups but CNA will not work.
Using CPPM v6.0 (although patching to 6.1 as I write this) and AOS 6.4.2.1. iPhone is on OS 7.2
Any ideas of where else I should look?
Cheers
Davey
