CMX Visitor Connect - How to block Whatsapp Messenger?

[steven.pw.lau]

Has anyone successfully created a Pre-Auth ACL to block Whatsapp messenger from connecting prior to authentication?

I understand that in some posts, there were suggestions to block Whatsapp via blocking access to c.whatsapp.net and s.whatsapp.net, but Pre-Auth ACL only supports IP address.

I've tried to be more specific in the Pre-Auth ACL by only allowing traffic to the MSE before authentication but whatsapp still gets connected.. hmmm..

Any ideas?

Hi,

DNS based ACL support from 7.6.x code onward. 

Are you running supported code ?

Thanks.. I totally forgotten about that...

But I've just realized, I'm not able to block whatsapp on iphone because of the TCP multipath in iOS 8.

Whatsapp will fallback to the cellular data when the app can't get through the wireless LAN.
