If you have a static IP, or dynamic DNS set up, you can set up your own remote access with a reverse proxy like nginx. The nice thing is I get to use my own SSL certificate and all the actual streaming goes directly to my server, not through their proxies.

The only "hacky" part about it is that the Admin dashboard shows "Not available outside your network", even though everything works perfectly.

Everything else is "a hack" in the sense that it is literally just the way to get Jellyfin working outside your network too.
