First things first, the setup is currently up and running. but i would like to modify it to use a reverse proxy through my personal domain.
Currently, i’m using an old pc with Truenas and a jail with jellyfin in it. i’m connecting to it with the free Fritz!Box VPN service.
but that’s stupid and slow. so i’ve bought a domain at godaddy.com. but i don’t understand the principle of whatever is managing the domain knowing the public IP-adress of my server. i’ve heard of Caddy, but it’s also running locally, so i don’t understand how i connect the pc to the domain.
if anyone could simplify this down for me, it’d be very helpful.
I assume you have a dynamic ip. what I did for that scenario: setup a dyndns hostname somewhere, configure a subdomain (e.g. jellyfin.example.com) with a cname dns record pointing to the dyndns hostname. you will have to setup updating of the dyndns hostname, this can be done in the fritz box and port forwarding to your jellyfin pc.
IPv6 may also “just work” nowadays, too, especially if the aim is to connect from mobile or other consumer networks. Corporate environments are still hit & mostly miss.
you mean without a dynamic hostname in between? but then you would still need to know about a changed prefix, wouldn’t you?
Dynamic DNS is probably still required, unless his ISP issues dedicated or very long term IPv6 leases.
