Curious Old Man Wondering About Accessing EMBY outside of LAN

Tailscale version: (dsmith44’s) Docker Image
Your operating system & version: Unraid Version: 6.10.3

My (new) isp will not allow me to open/forward ports and I just want to let several friends access my Emby Media Server. I searched the Google, then Reddit & Emby forums but can’t find any how-to’s or helpful info.
Sorry but I am completely new to Tailscale and tbh this is the only thing I will probably ever need to do with it.

  1. Is this possible?
  2. If so would I have to set up (Tailscale) user accounts for each of my friends and have them run Tailscale too so that they can connect to my Emby server?
    Any help will be greatly appreciated!

Thanks for all the help guys! Great community!
