Alright so I already had a quick look, sooner than I intended. Got too excited.
At a glance tho I love what I see. There’s an official nicotine+ package in the Pacman repository for Arch Linux so that’s a plus. I forwarded the port with no issue, I got a decent network setup so I got fixed internal IPs and could forwarded the port securely as possible.
It also looks like it plays nicely with how I got my NAS setup and how I mount files internally to my PC. This could be a bit of a rabbit hole and a great learning experience for me. Thanks to everyone for the suggestion/tips.
I’ll love to self-host this down the line on my server so I can better provide everyone with my files even when my usual PC isn’t on.
