Requirements

Before starting, make sure you have the following:

  • A Windows VPS (Windows Server 2016 / 2019 / 2022 / 2025)

  • Administrator access to the server

  • Open firewall port (UDP)

  • RDP access to the VPS

If you do not have one yet, you can get a Cheap Windows VPS with instant activation and deploy WireGuard within minutes.


Step 1: Download WireGuard for Windows

  1. Connect to your Windows VPS using Remote Desktop (RDP).

  2. Open your browser and go to:

  1. Download the WireGuard Windows Installer.

  2. Run the installer and follow the setup wizard.

  3. Click Install and allow the driver installation.

After installation, the WireGuard application will open automatically.


Step 2: Create WireGuard Server Configuration

Now we need to create a VPN configuration.

  1. Open WireGuard.

  2. Click:

Add Tunnel → Add Empty Tunnel

WireGuard will automatically generate:

  • Public Key

  • Private Key

Example configuration:

[Interface]
PrivateKey = SERVER_PRIVATE_KEY
Address = 10.0.0.1/24
ListenPort = 51820

[Peer]
PublicKey = CLIENT_PUBLIC_KEY
AllowedIPs = 10.0.0.2/32

Explanation:

ParameterDescription
PrivateKeyServer private key
AddressVPN internal network
ListenPortVPN port
PeerConnected client

Save the configuration.


Step 3: Allow WireGuard Port in Windows Firewall

WireGuard uses UDP port 51820 by default.

Open PowerShell as Administrator and run:

New-NetFirewallRule `
-DisplayName “WireGuard VPN” `
-Direction Inbound `
-Protocol UDP `
-LocalPort 51820 `
-Action Allow

This allows VPN clients to connect to the server.


Step 4: Enable IP Forwarding

To allow VPN traffic through the server, enable IP forwarding.

Open PowerShell as Administrator:

reg add HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters /v IPEnableRouter /t REG_DWORD /d 1 /f

Then restart the server.


Step 5: Create Client Configuration

Now create a configuration for your device (PC, phone, etc).

Example client config:

[Interface]
PrivateKey = CLIENT_PRIVATE_KEY
Address = 10.0.0.2/24
DNS = 1.1.1.1

[Peer]
PublicKey = SERVER_PUBLIC_KEY
Endpoint = YOUR_SERVER_IP:51820
AllowedIPs = 0.0.0.0/0
PersistentKeepalive = 25

Replace:

  • YOUR_SERVER_IP with your VPS IP address

Example:

Endpoint = 192.168.1.10:51820

Step 6: Connect to the VPN

Install WireGuard on your device:

  • Windows

  • macOS

  • Android

  • iOS

  • Linux

Import the configuration file.

Click Activate.

If configured correctly, your device will now connect to your Windows VPS VPN server.

You should see the IP address of your VPS.

This means your VPN is working correctly.
