Setting up WireGuard VPN on Linux Server (2024)

Setting up WireGuard involves configuring a server and client. In this guide, we’ll walk through setting up a basic WireGuard server and client. This example uses a Linux-based system, but the process is somewhat similar across other platforms.

1. Install WireGuard:

On a Debian/Ubuntu Server:

bash

sudo apt update
sudo apt install wireguard

On a CentOS/RHEL Server:

First, enable the EPEL repository:

bash

sudo yum install epel-release -y

Then, install WireGuard:

bash

sudo yum install wireguard-dkms wireguard-tools -y

2. Server Configuration:

Generate Server Keys:

bash

cd /etc/wireguard/
umask 077
wg genkey | tee server_private_key | wg pubkey > server_public_key

Create and Edit Server Configuration:

bash

nano /etc/wireguard/wg0.conf

Enter the following, adjusting as necessary:

css

[Interface]
Address = 10.0.0.1/24
ListenPort = 51820
PrivateKey = [YourServerPrivateKeyFromAbove]
[Peer]
PublicKey = [YourClientPublicKey]
AllowedIPs = 10.0.0.2/32

3. Client Configuration:

Generate Client Keys:

This step can be performed on the server for simplicity, or directly on the client.

bash

wg genkey | tee client_private_key | wg pubkey > client_public_key

Create and Edit Client Configuration:

If you’re on the client:

bash

nano /etc/wireguard/wg0.conf

Enter the following, adjusting as necessary:

css

[Interface]
Address = 10.0.0.2/24
PrivateKey = [YourClientPrivateKeyFromAbove]
[Peer]
PublicKey = [YourServerPublicKey]
Endpoint = [YourServerIPAddress]:51820
AllowedIPs = 0.0.0.0/0
PersistentKeepalive = 25

4. Start and Enable WireGuard:

On the Server:

bash

sudo wg-quick up wg0
sudo systemctl enable wg-quick@wg0

On the Client:

bash

sudo wg-quick up wg0
sudo systemctl enable wg-quick@wg0

5. Test the Connection:

From the client, you should be able to ping the server using its WireGuard IP:

bash

ping 10.0.0.1

Final Notes:

  1. Always replace placeholders like [YourServerPrivateKeyFromAbove] with the actual values.
  2. The server’s AllowedIPs for the client is restrictive to only allow the client’s WireGuard IP. If you add more clients, add more [Peer] sections to the server config and adjust IPs accordingly.
  3. The client’s AllowedIPs is set to 0.0.0.0/0, which means all traffic will be routed through the VPN. Adjust this if you need split tunneling.
  4. The PersistentKeepalive setting helps with NAT/firewall traversal.
  5. Ensure your server’s firewall allows incoming connections on the chosen WireGuard port (51820 in this case). Adjust firewall settings as necessary.
  6. This is a basic setup; there are many other configurations possible based on your needs. Always remember to secure and monitor your server.
