How to configure?
The first step is to register on the Tailscale platform to download the installer.
Repeat the same procedure on the computer you want to add to the Tailscale network.
The server can already be pinged as they are all on the same VPN network.
You can also access RDP through the VPN.
Isolating the RDP
Just configure the firewall by setting the VPN IP of the computer that will access the VPS, and it will lose RDP access via the public IP and respond only through the VPN.
