For clients to use WireGuard it must first be enabled and configured on the server. Once the server and client have WireGuard configured a OVPN and WG button will be shown when connecting on the client to select the protocol. The server must allow the client to access the HTTPS port to allow WireGuard connections to be authenticated.

Once WireGuard is separately installed the connect button will display OVPN and WG buttons to select the connection type. If the button is not shown the client did not detect the WireGuard installation.

Linux Client

WireGuard must be separately installed on the client. The wireguard-tools and wireguard-dkms packages are required. Use the command sudo dkms status to verify the DKMS module is available. If sudo dkms status does not show the module with the current kernel version restart the server and run sudo dkms autoinstall.

sudo curl -o /etc/yum.repos.d/jdoss-wireguard-epel-7.repo https://copr.fedorainfracloud.org/coprs/jdoss/wireguard/repo/epel-7/jdoss-wireguard-epel-7.repo
sudo yum -y install kernel-devel kernel-uek-devel wireguard-dkms wireguard-tools
sudo dkms autoinstall
sudo dkms status
sudo reboot

Using WireGuard on Ubuntu may require the resolvconf package.

Windows Client

The WireGuard Windows package must be installed separately.

macOS Client

The Homebrew packages bash and wireguard-tools must be separately installed.
