Yes, the public one. I just use synology ddns as the public address. I’m good with programming, but when it comes to IT stuff, I’m dead in the water. So, their infrastructure helped

I used synology and reverse proxy. It was pretty easy to set up. The tricky part was going into jellyfins setting and connecting your reverse proxy to the path you made.

Overall my kids and family can now access it anywhere.

Yea I think you can find one at “5 below” or “best buy”
