Title: Apple Facetime quality more than bad
Post by: ohne on June 18, 2022, 09:43:53 pm: Hey!

Ever since I switched to opnsense I can't make Apple Facetime work like it should be. The quality is so bad that people turn of their local wifi and use their slower mobile connections to get at least a steady connection.

Correct me if I'm wrong but Facetime uses STUN to connect the peers 1:1 without the detour to the apple servers. So I tried capture packages between a Macbook and an iPhone to see if this is working and in my opinion it's not?!

Can someone give me some hints how to solve this problem? The tcpdump looks like this:

10.20.10.25 is the IP of the macbook (inside vlan10, connected to a tp-link eap 660)
178.117.134.62 is the IP of an iPhone 12 which is connected to mobile internet

Code: [Select]

Perhaps someone else got this problem. There shouldn't be a bandwith related problem since the connection is 300/50 and is operating normal.

Thank you!

Edit:

Also when the connection is established logs are getting flooded which you can see in the attached screenshot.
