ziti-tunnel-apple VS passepartout-app

Mac and iOS tunnelers are here: https://github.com/openziti/ziti-tunnel-apple

Here's the source code for a VPN (Packet Tunnel Provider) that works on iOS and macOS: https://github.com/openziti/ziti-tunnel-apple. You can find a packaged version of it in the app store under "Ziti Mobile Edge".

I also have Ziti Mobile Edge currently in the app store. This is part of the OpenZiti open source project, and you can find the source code here.

I've been looking for the past days for a solution to get NextDNS and ProtonVPN seamlessly working together on my iPhone and found several workarounds, but none of them worked or worked stable enough. I prefer the advantages of NextDNS over Netshield. Then I remembered I purchased Passepartout quite a while ago (available in the App Store, also for iPad and Mac) and since it's a very user-friendly, flexible OpenVPN Client I expected it to have a possibility to enter custom DNS server, so I would be able to use NextDNS for parental controls et cetera instead of ProtonVPN DNS servers. I started fiddling, but to no avail, unfortunately I still had no DNS-resolution. I mailed the developer of Passepartout and got a reply within the hour pointing me to Github, to this closed issue: https://github.com/passepartoutvpn/passepartout-apple/issues/171#issuecomment-786809247. It works flawlessly and as I already had ProtonVPN configured, I only had to add an NexDNS ip address to the config, and reconnected and my problem was solved!
