How to implement certificate based access to self hosted services? (lemmy.world)

I am hosting few services for my friends and family on my server. Due to devices limitations, I can't install VPN on TVs etc. Is it possible to restrict the access to only those users that have a certificate issued by me?

I doubt you'll be able to install client certificates on TVs either. Typically you'd establish a site to site VPN in each location's network stack.

I am hoping it might work. It's Android TV. So it should support certificates. Site to site VPN is a bit challenging. I will try to explore the mTLS option suggested here.

Thanks!

Personally I use Caddy reverse proxy server and Pihole. I have configured my IP as a domain name in local DNS (example.com).

Caddy supports automatic TLS 1.3 support. So I just copied the CA file snd I installed to all of my devices (even in my Oculus Quest 2). I want to watch movies? I am coming to movies.example.com. i want to read my books? bookd.example.com.

Caddy configuration is very easy, even using containers with docker.

So you have configured mTLS in caddy? Can you point me to any resources that go through how to do it?

Are you able to open it to the internet and put these services behind an auth proxy? that might be the way to do it. Or if it already has login you might be able to put it behind a cloudflare WAF or similar and restrict bots and bad actors.

It already has authentication. The problem with cloudflare WAF is that my application is streaming videos, that is against the Cloudflare's ToS.

^ that is the way. works well on desktop browsers, but others like mobile often don't support mtls :(
