Windows registry configuration

This page provides Windows registry information for the official Windows Tailscale client.

The registry file will configure Tailscale to use {{.URL}} as its control server.

Caution

You should always download and inspect the registry file before installing it:

curl {{.URL}}/windows/tailscale.reg

Installation

Headscale can be set to the default server by running the registry file:

Windows registry file

  1. Download the registry file, then run it
  2. Follow the prompts
  3. Install and run the official windows Tailscale client
  4. When the installation has finished, start Tailscale, and log in by clicking the icon in the system tray

Or

Open command prompt with Administrator rights. Issue the following commands to add the required registry entries:

REG ADD "HKLM\Software\Tailscale IPN" /v UnattendedMode /t REG_SZ /d always
REG ADD "HKLM\Software\Tailscale IPN" /v LoginURL /t REG_SZ /d "{{.URL}}"

Restart Tailscale and log in.

Apple configuration profiles

This page provides configuration profiles for the official Tailscale clients for iOS and macOS.

The profiles will configure Tailscale.app to use {{.URL}} as its control server.

Caution

You should always download and inspect the profile before installing it:

curl {{.URL}}/apple/macos

Profiles

macOS

Headscale can be set to the default server by installing a Headscale configuration profile:

macOS profile

  1. Download the profile, then open it. When it has been opened, there should be a notification that a profile can be installed
  2. Open System Preferences and go to "Profiles"
  3. Find and install the Headscale profile
  4. Restart Tailscale.app and log in

Or

Use your terminal to configure the default setting for Tailscale by issuing:

defaults write io.tailscale.ipn.macos ControlURL {{.URL}}

Restart Tailscale.app and log in.
