I checked a handful of iOS VPN clients for other VPN providers and found none with an option about terminating existing connections/sockets when establishing the VPN tunnel. However, the option does not exist in their iOS software.

Interestingly, the Windscribe desktop VPN client software has an option for this, called "Kill TCP sockets after connection" (see TCP Socket Termination). In iOS 13 and 14, this does not happen, at least not by default. Connections that exist at the time the VPN tunnel is created, should be terminated and re-started so that they travel through the VPN tunnel. What ProtonVPN wrote about is a data leak, rather than a DNS leak. Aug 19, 2022: In May 2020, when iOS was at version 13.3.1, Mullvad had also warned about this: iOS vulnerability puts VPN traffic at risk. The nature of the bug is that the VPN tunnel does not assimilate all the bits. In researching my Defensive Computing with a VPN writeup, I ran across a March 2020 blog by ProtonVPN, VPN bypass vulnerability in Apple iOS, that describes a bug in iOS 13 and 14. Things are more complicated on an iPhone which does both Wi-Fi and 4G/5G/LTE. That the tunnel assimilates all the bits and bytes coming and going between the device in question and the Internet :-) I refer to "the tunnel" because the iPad I tested with is Wi-Fi only. I set out to verify that the VPN tunnel is the all-consuming thing it's supposed to be. The three VPN apps that I tested with had it off by default, and I left it off. All VPN client software that I have seen, that offers split tunneling has it off by default. Granted, some VPN software supports an option called split tunneling which breaks this simple rule, but that does not interest me. Certainly most data passes through the VPN tunnel, but I was curious about all data. Does it? That's what I set out to verify. Once a VPN connection (the official term is a "tunnel") is established, all data coming and going from the VPN-connected device is supposed to go through the VPN.

This blog is about a less than obvious VPN test, one that requires a professional class router to confirm. Some things are obvious, like checking for a new public IP address, new DNS servers and checking that WebRTC is disabled. The VPN page of my site has a section with assorted tires that can be kicked to verify that a VPN is working. Views of this page went from about 2,000 to about 76,000.

Update August 17, 2022: Ars Technica picked this up: VPN security - iOS VPNs have leaked traffic for more than 2 years, researcher claims. This data leak was first publicized by ProtonVPN in March 2020 and iOS v13. The latest version of iOS that I tested with is 15.6.1. I confirmed this using multiple types of VPN and software from multiple VPN providers. This is not a classic/legacy DNS leak, it is a data leak. Data leaves the iOS device outside of the VPN tunnel. But, over time, a detailed inspection of data leaving the iOS device shows that the VPN tunnel leaks. The iOS device gets a new public IP address and new DNS servers.
