Copy the https link and enter it in your browser and you will have to login on the “Tailscale” website, you should see a “Connect” button, press it and you should see a “Login Successful”.
After a few seconds you will be redirected to the console with all the machines are connected.
Under the Anybus Defender name you will see "Subnets" hovering over it you will see "This machine has unapproved routes", to remedy this press the three dots on the right and then "Edit route settings", tick the box next to the subnet you added and then save, this will allow you access to the LAN subnet of the Anybus Defender when you are connected by Tailscale.
On the Anybus Defender under “Firewall” -> “Rules” go to the "Tailscale" interface and add a new rule:
