With hackers and cyber-attacks on the rise, protecting sensitive data has become a top priority. Many companies use VPNs to ensure that their communications are secure and private. A VPN server helps to encrypt the data sent over the internet, making it harder for outsiders to access. However, while there are many VPN services available, some businesses prefer to build their own VPN server.
But why would you want to know how to build a VPN server? And how can you set up a VPN server yourself? Don’t worry; building your own VPN server is easier than you might think, and we’ll guide you through the steps. In this guide, we’ll explain why it might be beneficial to build your own VPN server and show you how to do it, whether you’re using cloud services or setting it up via a router.
Why Build Your Own VPN Server?
Building your own VPN server might sound complicated at first, but it offers many benefits. For businesses, it can be a more cost-effective, customizable, and secure way to ensure data privacy. Let’s look at some of the reasons why you might want to create your own VPN:
Increased Control
When you build your own VPN server, you have full control over the configuration. You can set it up exactly how you want, adjusting settings to fit your business’s specific needs. This is especially important for companies that require additional layers of security or customization.
Cost-Effective Solution
Although VPN services are available, they often come with a monthly subscription fee. By building a DIY cheap VPN, you can save on recurring costs. It can be more economical in the long run, especially for small businesses looking to cut down on expenses.
Security
When using a commercial VPN service, your data passes through their servers. While most VPN providers are trustworthy, there’s always a chance that your data could be compromised. With your own VPN server, you know exactly where your data is and who has access to it.
No Third-Party Dependence
By creating your own VPN, you reduce your dependency on external providers. If a commercial VPN provider experiences downtime or technical issues, it can disrupt your business operations. A private VPN server ensures that you have control over your uptime and reliability.
Flexibility and Customization
Commercial VPNs might offer different features than your business needs. By building your own, you can customize it to fit your company’s unique requirements. Whether you adjust bandwidth limits or add specific encryption protocols, the power is in your hands.
How to Build A VPN Server? Step by Step Guide
Now that you understand the benefits of building your own VPN server let’s look at how actually to set one up. There are two main ways to do this: by using cloud services or setting it up through a router.

Building a VPN Server in the Cloud
One of the easiest ways to build a VPN server is by using cloud services. Many businesses use cloud platforms like Amazon Web Services (AWS), Google Cloud, or Microsoft Azure to host their VPN servers. Here’s a step-by-step guide on how to build a VPN server in the cloud.
Step 1: Choose a Cloud Service
The first step is to choose a cloud service provider. AWS, Google Cloud, and Microsoft Azure are popular options. These platforms offer flexibility, reliability, and scalability, making them ideal for businesses looking to host their own VPN server. While they may have different pricing structures, they all provide free trials or low-cost options for smaller setups.
Step 2: Set Up a Virtual Machine (VM)
A VPN server requires a virtual machine (VM) to run. Think of a VM as a virtual computer that operates on the cloud. When you choose a cloud service provider, you’ll need to create a VM that will act as your server.
To set up a VM:
- Log into your cloud service account.
- Select the region closest to your business for better performance.
- Choose the operating system for your VM (Linux is commonly used due to its security and flexibility).
- Configure the machine type based on your business’s needs. A basic setup should work fine for small—to medium-sized companies.
- Launch the VM.
Step 3: Install VPN Software
Once your Virtual Machine (VM) is running, you will need to install VPN software on it. There are many VPN software options available, each offering different features based on your business needs. You can choose one that best fits your requirements, whether it’s an open-source solution or a commercial one.
After selecting the VPN software, follow the installation instructions provided by the vendor. Most VPN software comes with detailed guides to help you through the installation process. Once the software is installed, you’ll need to generate encryption keys and configure your VPN server settings. This may involve choosing encryption protocols, setting up user authentication, and defining how your VPN will handle data traffic.
Step 4: Configure Your VPN Settings
Once your VPN software is installed, it’s time to configure your VPN settings. Here, you can define how the VPN should function, including encryption protocols and data routing options. Most businesses opt for AES-256 encryption, which is one of the strongest available.
Step 5: Test Your VPN
Before rolling out your VPN to your employees or team members, you’ll want to test it to make sure everything works properly. Connect a device to your VPN server and check the connection speed and security features. If everything is running smoothly, congratulations! You’ve just built a VPN server in the cloud.
Building a VPN Server via a Router
If you prefer not to use cloud services, another option is to build a VPN server using a router. Some routers come with built-in VPN capabilities, making it easier to set up a VPN for your business. Here’s how to do it:
Step 1: Check Your Router
The first thing you’ll need is a router that supports VPN server functionality. Not all routers have this feature, so you may need to upgrade if your current router doesn’t support VPN configurations. Routers from brands like Asus, Linksys, and Netgear often include VPN server support.
Step 2: Install VPN Firmware (if needed)
If your router doesn’t support VPN configurations out of the box, you can install custom firmware like DD-WRT or OpenWrt. These custom firmware options unlock additional features, including VPN support. Be cautious during installation to avoid damaging the router.
Step 3: Enable VPN Server Functionality
Once you have the right router or firmware, log into your router’s settings using a web browser. Navigate to the VPN section and enable the VPN server feature. This process varies depending on the router, so refer to the manufacturer’s documentation for specific instructions.
Step 4: Configure VPN Settings
Next, configure the VPN settings. Similar to the cloud setup, you’ll need to choose encryption protocols, set up user authentication, and define other preferences. Some routers offer a simple setup wizard, while others may require more manual configuration.
Step 5: Connect Devices to Your VPN
Once your VPN server is set up on the router, you can connect devices to it. For most routers, you’ll receive a configuration file that you can install on your devices. This allows employees to connect to your business’s VPN network securely, even when they’re working remotely.
Building a VPN Server via Raspberry Pi (Bonus Option)
For those who want to experiment further, a fun and inexpensive option is to create your own VPN server using a Raspberry Pi. This method is ideal for small-scale personal use or as a DIY project.
Step 1: Purchase a Raspberry Pi
A Raspberry Pi is a low-cost, compact computer that’s perfect for building a small-scale VPN server. You can buy a Raspberry Pi for around $35, making it an affordable option for a DIY cheap VPN. Make sure to get a power supply, a microSD card, and an Ethernet cable or Wi-Fi adapter, depending on how you want to connect it to the internet.
Step 2: Install Raspbian OS
Raspberry Pi runs on Raspbian OS, a lightweight operating system based on Debian. You can download Raspbian OS from the official Raspberry Pi website and install it on your microSD card. Once installed, connect your Raspberry Pi to a monitor, keyboard, and mouse and boot it up.
Step 3: Install OpenVPN
Once Raspbian OS is set up, install OpenVPN on your Raspberry Pi by following the same steps outlined earlier for cloud-based setups. Raspberry Pi has enough processing power to run a VPN server, though it may be slower than cloud-based solutions.
Step 4: Configure Port Forwarding
If you’re using your Raspberry Pi behind a router, make sure to set up port forwarding to allow external devices to connect to your VPN server. This step is similar to the process for router-based VPN servers.
Step 5: Connect to Your Raspberry Pi VPN
After setting everything up, you can connect your devices to your Raspberry Pi VPN server. This is a fun and educational way to create your own VPN and a cost-effective solution for personal use.
How to Connect to Your Newly Created VPN Server?
Now that your VPN server is fully configured and running, it’s time to connect to it. The process of connecting to your VPN server will vary slightly depending on the operating system and device you’re using, but the general steps remain the same. Below is a more detailed guide to help you successfully connect your devices to the VPN server you’ve built:
1. Download the VPN Client
To connect to your VPN server, you’ll need a VPN client installed on your device. A VPN client is software that allows your device to communicate securely with the VPN server. Different VPN clients are available depending on the operating system you are using (Windows, macOS, Linux, Android, iOS, etc.).
For example, most VPN software providers offer their own sample VPN clients for various platforms. Alternatively, you can use any generic VPN client that supports the protocols you’ve configured on your server. Make sure that the client you choose is compatible with the operating system of the device you’re using. Here’s how you can do this for common devices:
- Windows/Mac/Linux: You can download a VPN client from the VPN software provider’s website or use built-in VPN clients like the one in Windows.
- Android/iOS: Go to the Google Play Store or Apple App Store and search for a VPN client that supports the protocols you have enabled on your VPN server.
Once the client is downloaded, install it following the provided instructions.
2. Install the VPN Profile or Configuration File
After you’ve installed the VPN client, the next step is to configure it so that it connects to your VPN server. To do this, you’ll need a VPN profile or configuration file. This file contains all the settings your VPN client needs to know, such as the IP address of the VPN server, encryption protocols, and authentication methods.
There are two common scenarios for obtaining this configuration file:
- For Cloud-Based VPNs: When you set up a VPN in the cloud, the server usually generates a configuration file (sometimes in .ovpn or .conf format) that you can download directly from the server dashboard or control panel. The file contains the necessary information to connect to your VPN server, such as server IP addresses, port numbers, and encryption keys.
- For Router-Based VPNs: If you have set up the VPN through your router, your router’s admin interface might generate a VPN configuration file for you. This file is usually located in the VPN settings section of your router’s configuration panel. You may need to export the profile and save it on the device you intend to connect from.
Once you’ve downloaded the configuration file to your device, you’ll need to import it into your VPN client. Here’s how:
- Windows/Mac: Open the VPN client and look for an option to import or add a profile. Select the configuration file you downloaded.
- Android/iOS: After downloading the configuration file, open the VPN client app and look for an option to import or add a new connection. Then, choose the file from your device’s storage.
In some cases, instead of a file, you may need to manually input the connection details (e.g., the server’s IP address, username, and password).
3. Configure the VPN Connection (Optional)
Most VPN clients will automatically configure the connection based on the profile or file you imported, but you may want to tweak some settings depending on your needs. This step is optional but can be useful if you want more control over your VPN connection.
Some common configuration options include:
- Encryption protocols: To balance speed and security, you can specify the encryption method (e.g., AES-256) or change the VPN protocol (e.g., OpenVPN, WireGuard, or L2TP).
- Port number: Adjust the port number your VPN client uses to connect to the server. This can be useful in bypassing network restrictions.
- Reconnect settings: You can configure the client to reconnect if the VPN connection drops unexpectedly automatically.
These settings vary between clients, but it’s worth exploring them to ensure your VPN connection is optimized for your business’s specific requirements.
4. Connect to Your VPN
Once the VPN client is installed and the configuration file has been imported, you’re ready to connect to your VPN server. This is the moment of truth!
Here’s how you connect:
- Windows/Mac/Linux: Open the VPN client, select the profile you just installed, and click “Connect.” The client will initiate a connection with your VPN server using the details provided in the configuration file.
- Android/iOS: Open the VPN app, find the profile, and tap “Connect.” The app will start routing your internet traffic through your VPN server.
Once connected, you’ll typically see a confirmation message indicating a successful connection. Some VPN clients may display the IP address of your VPN server or give you status updates about the connection, such as encryption protocol and session duration.
5. Test the Connection
Testing the connection is a crucial step to ensure that your VPN is working correctly and that your traffic is being routed securely through your new VPN server. Here’s how you can verify that everything is functioning as expected:
- Check Your IP Address: One of the easiest ways to test if your VPN is working is by visiting a website like WhatIsMyIP.com or IPLeak.net. These websites display the IP address associated with your current internet connection. When connected to your VPN, the displayed IP address should match the IP address of your VPN server, not your local device or ISP’s IP address.
- Test for DNS Leaks: DNS leaks can reveal your actual location or ISP even when connected to a VPN. Visit DNSLeakTest.com to ensure that your DNS requests are also routed through the VPN server and not your local ISP.
- Check Your Connection Speed: Sometimes, VPNs slow down your internet connection due to encryption and routing processes. Use a service like SpeedTest.net to measure your connection speed with and without the VPN enabled. While some drop in speed is normal, significant slowdowns could indicate a problem with your server configuration.
- Verify Security Settings: Lastly, if your VPN client allows it, review the security settings, such as encryption protocol, and ensure that they match the configuration you set on your VPN server. For example, if you set your server to use AES-256 encryption, confirm that this is reflected on the client side.
6. Maintain Your VPN Server
After successfully connecting to your VPN server, it’s essential to keep it maintained and secure. Make sure to update the VPN software regularly, apply any necessary patches, and monitor the server’s performance to ensure that it continues to meet your security and connectivity needs.
For businesses, especially those handling sensitive data, regular maintenance, and monitoring are crucial to protect against cyber threats and ensure uninterrupted service. If you’re using cloud-based servers, most providers offer tools to help automate updates and monitor server health.
