FaceTime and PIA
Has anyone had problems with PIA and FaceTime on OSX? I saw some had issues with it in iOS. I couldn't sign in at all even after closing PIA, since I had killswitch enabled. I had to reboot and connect FaceTime without PIA running in order to sign in.

PIA blocks IPv6.
Apple services will not send via PIA.

When using our client you will not be able to Facetime as this is a VOIP service and they require the use of a SIP server to operate and their server only support hostname connection. And as VOIP SIP servers typically utilize many IPs as failovers and for load balancing, to handle the traffic through the server. Because of the random nature of the server's connection (the server many use any IP in it's pool; there's no way to specify only 1 to use), there's no way to guarantee that the IP your VoIP connection uses at that time, is the one that was whitelisted on our network.
Additionally, VoIP services utilize a very large array of ports to route traffic; opening all of these ports would constitute a very large security risk, and could jeopardize the security of the VPN service; for this reason, we are unable to support VoIP usage in conjunction with our VPN service, to ensure the security and privacy of our client base.
