Disable Facetime for Guest Network

[kYutobi]

Is there a way to disable Facetime in Firewall & Traffic Shaping? Any help would be great.

Pretty sure you won't be able to do that via L3/L7 firewall rules. I think you can only do that via control over the device restriction settings via SM for example.

@NolanHerring I don't mean supervised or managed iPads through SM but just any guest that tries to make a factime call on wifi. I wasn't too sure if it could be done with L3-L7 rules.

The only thing I know of is if you were to block the actual public IP addresses that APPLE uses, but doing so I'm pretty sure you would also block everything else like App Store and what not.

Found some info here:

https://discussions.apple.com/thread/3963202

Blocking TCP 5223 and the following IP ranges:

17.173.0.0/16

17.178.0.0/16

17.133.0.0/16

Again with the caveat that this will likely take down multiple Apple services as the port is used for the Apple Push Notification Service and the ranges are big.

Also found a blog of someone who studied the Facetime protocol in detail in 2010:

Might have changed since then...

I also found some info on the Aruba website that they at least can identify the conversations to optimise QoS (not with the intention to block anything).

What you might be able to do is a packet capture of DNS queries, and then see if any of them mention FaceTime, and then try blocking those.

Thank you guys. I will continue to experiment and give it a try.
