Install WireGuard [Client] on Arch Linux



This is a very basic tutorial on how to install WireGuard on Arch Linux to use it as a VPN client. For example if you need maximum privacy while torrenting your favorite Linux distros.


pacman -S wireguard-tools


Generate keys

First up we need to generate our private and public key. The private key should reside in our configuration and the public key will be used by the other peers, in this case the server. If you have already been provided with a complete config file you can skip to the next section. Remember that you and the server and are not supposed to know each other's private key. You only need to exchange the public keys.

wg genkey | tee privatekey | wg pubkey > publickey

Print the keys and copy them for the following configuration.

cat peer1-privatekey && cat peer1-publickey

Configure your first tunnel

In this tutorial we'll use wg0 as the name for our WireGuard interface. If you already have a WireGuard configuration named wg0, make sure to use another name for this configuration.

Below is an example config for routing all traffic except local (192.168.1.*) through the VPN. If your local subnet is on e.g. 192.168.0.X

PrivateKey = `PRIVATEKEY`
PostUp = ip route add ` via`;
PreDown = ip route delete ``;

PublicKey = `PUBLICKEY`
AllowedIPs = ``,`::0/0`
PersistentKeepalive = 25

Starting WireGuard

Manually bring up the WireGuard interface and check for any errors.

systemctl start wg-quick@wg0
systemctl status wg-quick@wg0

You may want to bring up the interface automatically as a service with systemd.

systemctl enable wg-quick@wg0
