wireguard

Installation

Wireguard can be installed directly from apt

sudo apt install wireguard

Setup client from a configuration file

A configuration file will look something like this

[Interface]
Address = 10.200.200.3/32
PrivateKey = [Client's private key]
DNS = 8.8.8.8

[Peer]
PublicKey = [Server's public key]
PresharedKey = [Pre-shared key, same for server and client]
Endpoint = [Server Addr:Server Port]
AllowedIPs = 0.0.0.0/0
PersistentKeepalive = 21

1. Make sure that the filename of the configuration file can be a valid interface name. It should not have any special characters such as - or _.
2. Copy the configuration file into the /etc/wireguard directory.

Assuming the configuration file is called wg0.conf

sudo cp wg0.conf /etc/wireguard/wg0.conf

Usage

Run wireguard

sudo wg-quick up wg0

Close wireguard

sudo wg-quick down wg0
