I am kinna noob in such things, but recently started using jellyfin for media consumption that I run on my HP ELITEDESK tiny...
Was planning to give access to someone In the same city and I was told by another great member to use Tailscale..
I am yet to do that.. But this explanation of Tailscale by a guy on reddit just made my day.
You know how you passed notes in class? You just wrote your friend's name and passed it to the kid next to you and so on and so forth. You didn't need a mailing address on the note or a security envelope since it was a private space and everyone knew each other.
Now imagine one of your friends is in another school. Now you write your note but you have to seal it up in an envelope and write the other school's mailing address and send it out into the world with a public address. Imagine your school had an administrator who did that officially. Mrs Keller's class was in a different school but they know which school so they bundle up all the notes for that school in a postal box and send it out.
Once it reaches your friends school imagine there is someone who can open the letters and envelopes and then hand the note to the correct friend in the correct classroom.
That's a virtual private network. From your friend's perspective it was an insecure note without an address but it was sent from one classroom to another as if they were classrooms in the same school. They appear to be local even though there was a transparent step where the notes for distant schools are all securely packaged up and shipped using a public postal service.
All that Tailscale does is let you assign a local address like a classroom name and a student name and then it figures out where that student actually is, locks the note in a secure briefcase and ships it to the recipient where a Tailscale agent then unlocks the briefcase and hands the insecure note to the recipient on the other end
