Tailscale VPN

Info

This is an easy-to-use example for creating your own private VPN on Railway.

Create an account on tailscale.com.
Follow the instructions to install Tailscale on your own device that you want to connect to the VPN.
Go to the Settings tab, and to go Keys. Then, click on Generate auth key....
Select the options for making it Ephemeral and Reusable, then click Generate key.
Copy the key that it gives you. It looks something like tskey-h1M24bEnVnd-n8J2LteLAFJLm8HQn3m. (This is a fake key, don't bother trying it.)
Configure this starter, and put in the key as TAILSCALE_AUTHKEY.
Wait for it to finish deploying, and go to the admin page.
Where it says railway-app, click on the triple dots.
Then, click Edit route settings.... Then, turn on the option that says Use as exit node.
Configure your computer to use the exit node, and you're done!
