Using Fail2ban to protect exposed services (arvind.io)

I'm wondering if I'm starting to outgrow Tailscale... my wife keeps having networking issues on Android due to Tailscale, the Nvidia Shield kills the Tailscale app randomly, and my parents' TV doesn't have a Tailscale app...

I feel like the time is approaching to publicly expose some of my services to the internet...

Any other tips?

I use tailscale for my non-tech family.

I run a rPi with tailscale, pihole and nginx on it in their house. They connect to the their WiFi, get adblocking for free. They go to "http://homarr.sever/" pihole captures the request, sends it to nginx which reverse proxies to a homarr LXC on my server. From there they can click links to the services which are at "https://service/.######.xyz". Again, pihole captures the request, sends it to nginx which reverse proxies it over Tailscale to the appropriate LXC.

One poor soul runs a mini pc with 2 mirrored ssds attached, it runs everything above plus Syncthing. They have the privilege of running the remote back up for the server.

For apps on their phone, I intend to set their phone up with Tailscale and then just have the app go to "http://dockge:1337/"... Just as soon as I learn to write the access controls to allow admins to access everything, users to access services, and services to access nothing. I just looked and there's a gui now so I could maybe do it this winter.

    Honestly, I wouldn't.

    I only run it this way because a VPS had 0 WAF, and I'm terrified of opening ports. VPS is the well trodden ground, there's tonnes of guides. Mine's a hack job borne of necessity, it works though, and I am proud of what I cobbled together.

    It was my first time solving my own problems. I had my meager skill set, a basic idea of what I wanted, some vague notion of how I was going to achieve it, and a thick forehead to smash against the problem till it gave way for me.

    I am going to keep running it this way though. To access my server you need to HAVE a relay rPi, and you need to KNOW a password. That's two authentication factors right there, just built in.
