 - `Auth Key`: The key you received from tailscale in prerequisites above
 - `Userspace`: Now enabled by default, as it is _required_ when using local routes and as an exit node (see below). Userspace restricts clients to only accessing the GUI and Samba. This needs to be _unchecked_ if you need to give Tailscale full access to all the features inside TrueNAS SCALE (not just GUI/SMB, but RSYNC, PING and directly connect to other Tailscale IPs, etc).
