How to Reverse Proxy Jellyfin with Caddy on Docker (Beginner Friendly)

[TheDreadPirate]

This is why I love Caddy! You can totally forget about complicated 1networking stuff and just let Caddy/Docker handle it all with some application of dark magic.

Save yourself the headache and just lease a domain. Not sure if you can still get them for free, but it's only like $4/year to register a memorable domain. Personally I've been using Cloudflare (a bit more expensive, I think like $12/year) to manage my domain and DNS settings. The convenience as ultra-fast DNS propagation is totally worth it if you're homelab-ing. 

If you're hosting a sever at home it's in your best interest to get IPv6 set up. The huge advantage is that IPv6 restores end-to-end direct connections as was originally intended with the internet.

You get even quicker DNS propagation if your home router uses Cloudflare as the DNS provider.  At least for clients on your home network.

And Cloudflare has an API for updating your IP, so it is effectively like a DDNS service as well.
