====== WireGuard guide ======

[[https://en.wikipedia.org/wiki/WireGuard|WireGuard]] is a new VPN protocol, way faster and simpler than OpenVPN, without sacrificing security.\\
You can't use WireGuard if your ISP blocks UDP.

Please follow these steps to use the WireGuard VPN:


===== Create a key =====

You need a different key for each device. Skip this step if you already have an unused key.

To create a new key, go to [[https://arethusa.co/account/|My account > Services: VPN > WireGuard]] then click on "Create new WireGuard key".


===== Download a configuration file =====

Go to [[https://arethusa.co/account/|My account > Services: VPN > WireGuard]] then click on "Configuration file". Choose "automatic", unless you have specific reasons to force a protocol.

Do not share your configuration file. It contains your private key.


===== Install WireGuard =====

[[https://www.wireguard.com/install/|Download and install WireGuard.]]


===== Import the configuration file into WireGuard =====

  * **Windows:** Click on the WireGuard icon in the notification area, then click on "Add Tunnel".
  * **macOS:** Click on the WireGuard icon in the system tray, then "Import tunnel(s) from file...".
  * **Android/iOS:** Open the WireGuard app, press on "+" and choose "Import from file or archive".
  * **Linux/*BSD generic (command line interface):** No import needed.


===== Activate the tunnel =====

  * **Windows:** Click on the WireGuard icon in the notification area, then click on "Activate".
  * **macOS:** Click on the WireGuard icon in the system tray, then "arethusa_eu".
  * **Android/iOS:** Open the WireGuard app and toggle "arethusa_eu".
  * **Linux/*BSD generic (command line interface):** ''sudo wg-quick up arethusa_eu.conf''\\ To de-activate: ''sudo wg-quick down arethusa_eu.conf''


Once activated, [[ip_check|check your IP addresses]].


===== Notes =====

  * On Windows, only users members of the Administrators group can use WireGuard. With the [[https://git.zx2c4.com/wireguard-windows/about/docs/adminregistry.md|LimitedOperatorUI]] hidden setting you can allow members of the "Network Configuration Operators" group to start and stop the VPN.
