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?
If you are able to switch away from Proton VPN in the long run you could use the new tailscale/mullvad partnership to use mullvad as an exit node. https://tailscale.com/kb/1258/mullvad-exit-nodes/
I did think about it, but I use all of their services anyway, so for me it's plenty worth it. I save money on paying for a suit, rather than individual services here an there.
