Ask them to visit https://ipv4.icanhazip.com/ and give you back the number, then whitelist in your webserver, as well as your LAN/VPN range, deny rest. Explain they can only reach jellyfin from their home internet. Repeat if they get 403 forbidden after they get a new WAN IP.

That or VPN like openziti, wireguard but gets more complicated.

Welcome to gaming on Linux!

how to manage the games installed in Proton (virtual C drive)

They can be found in: ~/.local/share/Steam/steamapps/compatdata//pfx/drive_c/ For Elden Ring for example the path is: ~/.local/share/Steam/steamapps/compatdata/1245620/pfx/drive_c/

Biggest blockers are games with invasive and unsupported anti cheat or very new games. Check https://www.protondb.com/ for the latest reports on games.

Something like reverse dynamic DNS for end users? Hm, only if it would be easy to setup, is on the same level as a VPN client I'd say.

I don't consider Jellyfin a fully secure and audited application to host, unsecured endpoints come to mind, that and the less exposed to the whole internet the better.

Things like these scare me:

So far I've seen WAN leases expire after a long time, say months, or quarter year, so is doable. If becomes an issue I'll work with them on a VPN solution but is a pain for non-technical users or non-supported hardware. That's also why I explain "use from your home network only".
