So, I have a few services (Jellyfin, Home Assistant, etc) that I am running, and have been acessing via their IP’s and port numbers.
Recently, I started using NGINX so that I could setup entries in my Pi Hole, and access my services via some made up hostname (jellyfin.home, homeassistant.home, etc).
This is working great, but I also own a few domains, and thought of adding an SSL cert to them as well, which I have seen several tutorials on and it seems straight forward.
My questions:
-
Will there be any issues running SSL certs if all of my internal service are inward facing, with no WAN access? My understanding is that when I try to go to jellyfin.mydomainname.com, it will do the DNS lookup, which will point to a local address for NGINX on my network, which the requesting device will then point to and get the IP of the actual server.
-
Are there risks of anything being exposed externally if I use an actual CA for my cert? My main goal is to keep my home setup off of the internet.

Neat, might have to look more into that the next time I redo my setup.
DNS challenge is the way to go. I just did it couple of weeks ago. Here is youtube video of the process. He uses duckdns but I personally used cloudflares dns
