I would really really really like to have one device on my tailnet as the exitnode for all other devices on the tailnet. However, most VPNs make this really difficult. Is there any way to do this? I’ve read it’s possible with split-tunnelling, but ProtonVPN (which I use) doesn’t support that. I just installed Alpine Linux on my RPI 4b. And would like to use this as my exit node. Does anyone have any tips for how this could be done?
I’ve been trying to accomplish the exact same thing. In the same vein I’ve also been trying to setup a tailscale exit node with mitmproxy so that i can inspect mobile app traffic without having to fiddle with proxy configs on my phone each time. In relation to that i found this - https://www.aapelivuorinen.com/blog/2022/09/12/transparent-mitmproxy-tailscale-vm/
Let me know how you get on as I’m super keen on having both a VPN and mitmproxy setup as exit nodes.
A solution was posted in later comments, did you see?
