Question on setting up Jellyfin on my existing Porkbun domain

[snipy3]

Hello. I'm new to this whole thing, so bear with me. A lot of tutorials I see have users going down the path of DuckDNS, etc. I have yet to find a good tutorial that demonstrates how to setup a Jellyfin server on an existing domain (from Porkbun in particular), as well as one that discusses the potential security risks of doing so / how to limit access. I am running a server on my laptop and it works fine in my house, but I'd ideally like to host it on my website so I can access it remotely and invite friends and family to use it as well.

Is there a good guide for this that I could reference, even if it's not 1:1 with my setup?

you need to run a reverse proxy to be a little secure but the quickest is to add an A record on your domain to your home ip and port forward jellyfin on router. However since most of all us have a dynamic ip from our ISP it will eventually change and that is why most are using such things as duckdns so when their ip updates it changes it. Most routers have dynamic dns and that may help as the router does the ip push.

Thank you for explaining that. So to clarify, would duckdns still make sense in my use case? Is it possible to link that to my personal domain rather than using the duckdns address?

I'm assuming the end goal is something like Laptop running Caddy -> DuckDNS -> Porkbun domain
