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.
Yeah, that’s the part where I think there’s some misunderstanding. You don’t “connect” the server to your domain. Instead, there is a Nameserver (most run by your registrar, GoDaddy) that hosts a list of DNS records, that you can edit, which point to IPs. So you need to edit those to point to your public IP (or set up stuff like DynDNS if your IP isn’t static) and once that’s doneand the port forwarding is also set up properly in the Fritz!Box you should be able to connect.
That said, what’s wrong with VPN? Particularly if you’re using Wireguard VPN, which was recently added to Fritz!Box, there shouldn’t be any performance differences. Plus, it would be safer than exposing services to the whole internet, particularly if you’re not a networking expert.
