I’m kind of a noob at this so I just want to make sure I’m on the right track. Most of my experience is centered around using public trackers and qbitorrent with a VPN on my laptop and Android phone (using flud).
I would like to get started using Jellyfin to serve up media in my house and occasionally remotely with my phone. I have an older HP desktop that was formerly a business PC. I am currently resetting it back to a fresh install (probably Windows 10). I was thinking of putting Jellyfin on there and setting up Tailscale. I have already tested setting this up on a different computer just to learn the setup process and I got it working and was able to remote connect with my phone. I have Cox cable internet and I’m using their provided modem/wifi gateway so I probably don’t have many options for customizing that other than port-forwarding. I also don’t really need to set up any automation to download media automatically at this time. I basically want to be able to download movies the way I currently do and put them on the Jellyfin machine. What else do I need to know/do? What am I missing? and will I be able to just pull up Jellfin on my phone and cast media to my smart TV’s (they do not have Roku btw)?
Internal to your LAN/WLAN Jellyfin will work right out of the box it collects content from whatever folders you tell it too. Phone, smart TV, etc. You might need local clients on some devices.
Outside your local network it gets complicated, has security concerns. Certainly doable, but outside my expertise. If you want to serve outside your local network, PLEX is a similar, close source, software that can take care of the web for you.
