Hi, We are now having a packet traffic problem with our IPV4 VPN tunnel with the IPV6-only LTE provider. We found iOS consulted NAT64 to translate IPV4 to IPV6 address before sending the traffic to the tunnel, so the traffic will not go through by the IPV4 VPN tunnel. We wonder if NAT64 translation is done before or after iOS decides which network interface to use. Thank you, Ken

Hello, Regarding making split DNS supports the full tunnel, I've read this thread, I wonder if iOS16 supports the split DNS for the full tunnel or if it still remains the previous answer. Thank you!

Hello! We are currently working on our iOS project, and we plan to make a feature that the app could send an HTTP request every 10 to 15 mins while the app is in the background mode. We tried to use BGAppRefresh and BGProcessing, and we found the time interval is about 30 mins for BGProcessing (when the device is locked) and the time interval of BGAppRefresh is not guaranteed. From what we learned from Apple documents, the BGAppRefresh and BGProcessing time intervals are both controlled by the system. I want to ask if there are any ways to control the background refresh time to reach our goal, or if there are some other methods we could use. Appreciate anyone could answer this. Thanks!
