I would want to also remotely (from other wifis annd mobile LTE) access my dietpi.
For example to SSH into dietpi and install software/update etc.
Or access my jellyfin server and stream my home media library.
Using Wireguard works perfectly.
But I thought I could use Tailscale to get the same result without the ddns setup and the router config. (And Tailscale works good on fire tv/android tv devices)
So installation of Tailscale on dietpi works and installed it also on my iPhone +fire tv.
I see all machines in Tailscale admin console and that the vpn connection builds up.
I guess there is a misunderstanding what Tailscale is and how it is working. It is not something you can compare with Wireguard 1:1 as it has a different concept. Better you check Tailscale docs to get more inside. To allow sub net routing, some additional steps are needed Subnet routers and traffic relay nodes · Tailscale
