You've gotta be kidding me.

I’d recommend buying a domain through Cloudflare. Once you have one, you can create subdomains and point them to services running on your home server. Cloudflare’s dashboard makes the DNS side pretty straightforward.

I mean I cheated and used chatgpt to help figure it out. But it’s more or less 3 programs max running on whatever server you’re using and using the cloudflare UI to redirect the traffic to the right place

I mean not for free, but I did it for cheap. A good domain can cost you $5 a year, and you simply route your jellyfin to a sublevel like watch.mydomain.com

Fun part is you can also route your sonarr like sonarr.mydomain.com
