Access Home Network Using WireGuard VPN on Public VPS (Point-to-Site)

In today's digital age, having secure and reliable access to your home network from anywhere in the world is a must. However, this can be challenging, especially when you don't have a public address at home. One solution to this problem is to use a Virtual Private Network (VPN) to create a secure and encrypted tunnel between your home network and your devices. In this article, we will explore how to use WireGuard VPN on a public VPS (Virtual Private Server) to access your home network from anywhere in the world.

WireGuard is a modern, open-source VPN protocol that provides fast, secure, and reliable connectivity between your devices and your home network. It is designed to be easy to use and configure, making it an ideal choice for individuals and small businesses. WireGuard uses state-of-the-art cryptography and is highly optimized for performance, making it a great choice for real-time applications such as video streaming and online gaming.

A public VPS is a virtual server that is hosted on a remote server and can be accessed over the internet. Public VPS providers such as Oracle Cloud, DigitalOcean, and Linode offer free-tier plans that can be used to host a WireGuard VPN server. These free-tier plans usually come with limited resources, such as CPU, memory, and storage, but are sufficient for small-scale VPN deployments.

To set up WireGuard VPN on a public VPS, you will need to follow these steps:

Step 1: Create a Public VPS

First, you need to create a public VPS on a provider such as Oracle Cloud. You can do this by following these steps:

  • Go to the Oracle Cloud website and sign up for a free account.
  • Create a new virtual machine by clicking on the "Create a Virtual Machine" button.
  • Choose the free-tier plan and select the operating system (e.g., Ubuntu).
  • Configure the virtual machine settings, such as CPU, memory, and storage.
  • Click on the "Create" button to create the virtual machine.

Step 2: Install WireGuard VPN

Once you have created the public VPS, you need to install WireGuard VPN on it. You can do this by following these steps:

  • Connect to the public VPS using SSH.
  • Install the WireGuard VPN package by running the following command: sudo apt-get install wireguard
  • Configure the WireGuard VPN settings by editing the /etc/wireguard/wg0.conf file.

Step 3: Configure WireGuard VPN

To configure WireGuard VPN, you need to edit the /etc/wireguard/wg0.conf file. This file contains the VPN settings, such as the public key, private key, and IP address. You can configure the VPN settings by adding the following lines to the file:

[Interface]
Address = 10.0.0.1/24
ListenPort = 51820
PrivateKey = /etc/wireguard/private.key

[Peer]
PublicKey = /etc/wireguard/public.key
Endpoint = <public_vps_ip>:51820
AllowedIPs = 0..0.0/0

Replace <public_vps_ip> with the IP address of the public VPS.

Step 4: Generate Public and Private Keys

To generate public and private keys, you need to run the following commands:

sudo wg genkey | sudo tee /etc/wireguard/private.key | sudo wg pubkey | sudo tee /etc/wireguard/public.key

This will generate a public key and a private key, which you can use to configure the VPN settings.

Step 5: Start WireGuard VPN

To start WireGuard VPN, you need to run the following command:

sudo wg-quick up wg0

This will start the VPN and make it available to your devices.

To configure your device to connect to the WireGuard VPN, you need to follow these steps:

Step 1: Install WireGuard VPN

First, you need to install WireGuard VPN on your device. You can do this by following these steps:

  • Go to the WireGuard VPN website and download the client software.
  • Install the client software on your device.

Step 2: Configure WireGuard VPN

To configure WireGuard VPN, you need to edit the VPN settings on your device. You can do this by following these steps:

  • Open the WireGuard VPN client software on your device.
  • Click on the "Add" button to add a new VPN connection.
  • Enter the VPN settings, such as the public key, private key, and IP address.
