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?
Yes you can do this, you can use ANY device/node as an exit-node among your tailscale nodes.
You do need a server to setup the nodes though. Tailscale offer this as a paid service I believe, or you could run your own headscale (open source project) server yourself, this requires a lot more knowledge
I am aware I can run a tailscale exit node. But want to know if it is possible do so with the same node running protonvpn…
