WireGuard Installation on Arch Linux

Step-by-Step Guide to Install WireGuard on Arch Linux

1. Update Your System

Make sure your system is up-to-date:

sudo pacman -Syu

2. Install WireGuard

Install the WireGuard tools:

sudo pacman -S wireguard-tools

3. Install OpenResolv

Install openresolv to manage DNS for your WireGuard connection:

sudo pacman -S openresolv

4. Generate Keys

Generate a private and public key for your WireGuard configuration:

wg genkey | tee privatekey | wg pubkey > publickey

5. Create the WireGuard Configuration

Create a configuration file for the WireGuard interface (e.g., wg0.conf):

sudo mkdir /etc/wireguard
sudo nano /etc/wireguard/wg0.conf

Add the following configuration (adjust the Address, PublicKey, and Endpoint):

[Interface]
PrivateKey = <Your_Private_Key>
Address = 192.168.6.165/32
DNS = 1.1.1.1, 8.8.8.8  # Optional, can be commented out if using systemd-resolved

[Peer]
PublicKey = <Peer_Public_Key>
Endpoint = <Peer_Endpoint>:<Port>
AllowedIPs = 0.0.0.0/0, ::/0

Replace <Your_Private_Key>, <Peer_Public_Key>, and <Peer_Endpoint>:<Port> with your actual keys and the server’s details.

6. Start the WireGuard Connection

To bring up the WireGuard interface, use:

sudo wg-quick up wg0

7. Enable WireGuard on Boot

To ensure the WireGuard connection starts automatically on boot:

sudo systemctl enable wg-quick@wg0

8. Turn Off the WireGuard Connection

To bring down the WireGuard interface, use:

sudo wg-quick down wg0
