Private VPNs on VPS: the ultimate guide to safeguarding sensitive online activities

In today’s digital world, data breaches and surveillance are commonplace, while online privacy has become essential. A great way to safeguard your online trail is to use a Virtual Private Network (VPN). And while VPN services are widely available, did you know that hosting your own private VPN on a Virtual Private Server (VPS) provides even greater control and security? This guide explores how to set up a private VPN on a VPS.

Why use a private VPN?

A high-quality VPN service creates an encrypted (secure) tunnel between your device and the internet. It masks your real IP address and makes it more difficult for third parties to track you. Although VPNs are widely used for privacy, here are reasons why you’d want to set up a private VPN on your own VPS:

1. Full control. When using a commercial VPN service, all of your internet data flows through the provider’s servers. With a private VPN on a VPS, you manage all aspects of the server – no third-party logging or access to your sensitive information.
2. Better security. A private VPN eliminates the risks associated with trusting a third party to secure your data. You can choose the best encryption standards and monitor for suspicious activity.
3. Customization. You can configure the VPN how you like (e.g., bypassing geo-restrictions or enabling particular security measures).
4. Enhanced privacy. Hosting your own VPN means no data is shared, avoiding data logging or the very real risk of potential breaches in commercial VPNs.
5. Bypass geo-restrictions. A private VPN can help you access content as if you were in the VPS’s location so you can access geo-blocked websites and streams.

Choosing the right VPS provider

Before setting up a private VPN, you need to choose a high-quality VPS provider that fits your requirements. A VPS acts as the host for your VPN server, so choosing the right provider is key to performance and security. Some of the best VPS providers include:

Liquid Web

Liquid Web sets itself apart with fully customizable VPS plans (choose unmanaged or fully managed, add cPanel/Plesk licensing, etc.) and an industry-only migration-free path to Bare Metal Cloud. You can start as small as 1 CPU/1 GB RAM and, when your VPN volume grows, seamlessly “burst” into dual-Xeon, multi-TB dedicated hardware – without rebuilding or moving your IPs and configurations. Real-time system monitoring, proactive DDoS protection, and 24/7 “Heroic” support keep your private VPN running at peak performance. An enterprise-grade SLA (100% network and power uptime) ensures no dropped connections for business-critical traffic.

Hostinger

Hostinger is an affordable option with scalable VPS plans with data centers across the globe. It has a user-friendly interface and reliable uptime. It’s particularly favored by those who want a cost-effective and reliable hosting solution. Hostinger’s performance and customer support make it ideal for first-time users setting up a VPS.

DigitalOcean provides a simplified approach to VPS hosting with a developer focus. The platform supports scalable cloud infrastructure. It also offers flexible billing options and high-performance API tools. Known for its speed and ease of setup, DigitalOcean is a popular choice among tech enthusiasts and developers.

Kamatera

Kamatera is known for its high-performance cloud VPS hosting. With it, users can scale resources easily, meaning a VPN will remain fast and reliable even as usage grows. Kamatera is great for businesses that need high performance and uptime for critical applications – like a VPN server.

VPS-Hosting.com

VPS-Hosting.com is a premium provider known for its superior customer service and strong infrastructure. It’s slightly more expensive than the average provider, but offers high-level reliability and uptime. There’s Ubuntu and CentOS support, so it’s a perfect choice for a more secure and stable environment for a private VPN server.

When selecting a VPS provider, make sure they offer the required resources, like sufficient bandwidth, RAM, and CPU power to handle VPN traffic. Plus, check that the provider supports the operating system you’re running and offers strong security measures, like DDoS protection and secure data centers.

Choosing the right VPN protocol

The VPN protocol determines the level of security, speed, and compatibility with devices. Two of the most popular VPN protocols are OpenVPN and WireGuard.

OpenVPN

OpenVPN is an open-source protocol known for its security and flexibility. It uses high-tier encryption standards like AES-256. It’s widely compatible across various devices like Windows, macOS, Linux, and mobile platforms. However, it can be more complex to set up and slightly slower compared to some newer protocols. It also supports both TCP and UDP protocols – great for flexibility in network environments.

WireGuard

WireGuard is a newer protocol that is gaining popularity for its speed and simplicity. With a much smaller codebase than OpenVPN, WireGuard is easier to audit and configure. It uses modern encryption methods like XChaCha20 and Poly1305 resulting in both strong security and faster performance.

WireGuard is liked for its ease of use, so it’s a top choice for those looking for a streamlined VPN solution. Additionally, WireGuard is designed to be lightweight and is perfect for devices with limited resources, like smartphones or IoT (Internet-of-Things) devices.

WireGuard’s codebase is less than 4,000 lines, so it’s far more compact than OpenVPN’s several hundred thousand lines. This means less potential for vulnerabilities.

Step-by-step guide to setting up a VPN on a VPS

Next, I’ll guide you on how to connect to a VPS via SSH, which is usually done from a Linux or macOS system using the terminal. If you’re on Windows, the process is different.

Step 1: Prepare your VPS

After selecting a VPS provider, connect to the server via SSH. First, make sure the server’s packages are up to date. Run the following commands:

ssh root@your_vps_ip (put the actual IP address of your VPS here when connecting)

sudo apt update && sudo apt upgrade -y

Step 2: Install the VPN software

For OpenVPN:

Download and install the OpenVPN installer script by running:

wget https://git.io/vpn -O openvpn-install.sh

bash openvpn-install.sh

Then, follow the on-screen prompts to complete the OpenVPN setup.

For WireGuard:

Install WireGuard by running:

sudo apt install wireguard

Then, generate your private and public keys:

wg genkey | tee privatekey | wg pubkey > publickey

Proceed with creating the WireGuard server configuration as needed.

Step 3: Configure Firewall and Routing

Make sure your VPS’s firewall allows VPN traffic. For OpenVPN, open UDP port 1194. For WireGuard, open port 51820.

On Ubuntu, use UFW to configure firewall rules:

sudo ufw allow 51820/udp # For WireGuard

sudo ufw allow 1194/udp # For OpenVPN

sudo ufw enable

Enable IP forwarding to allow communication between the client and server:

sudo sysctl -w net.ipv4.ip_forward=1

Step 4: Set Up Client Configuration

After setting up the VPN server, generate a configuration file for the client. For OpenVPN, you’ll get a .ovpn file that can be imported into the OpenVPN client on your device. For WireGuard, create a configuration file with your private and public keys.

Step 5: Start the VPN Server

Once everything is configured, start the VPN server on your VPS.

For OpenVPN:

sudo systemctl start openvpn@server

sudo systemctl enable openvpn@server

For WireGuard:

sudo wg-quick up wg0

Step 6: Connect to the VPN

Install the OpenVPN or WireGuard client on your device. Import the configuration file for the client, and you should connect to your private VPN server.

Security best practices

To keep your private VPN secure:

• Regular software updates. Ensure that both your server and VPN software are regularly updated to patch vulnerabilities.
• Use strong encryption. For maximum protection, use AES-256 encryption.
• Use a kill switch. Set up a kill switch that disconnects your internet the moment your VPN connection drops. This stops data leakage.
• Monitor logs. Regularly check your server logs for unusual activity or unauthorized access attempts.
• Use MFA. For added security, implement two-factor authentication where possible.

Here are some additional considerations:

• Legal compliance. Verify that hosting a VPN server complies with the laws of your country. Certain jurisdictions have strict rules about encryption and VPN usage.
• Performance monitoring. Monitor the performance of your VPS to check whether it can handle the VPN traffic without slowing down.
• Backup configurations. Regularly back up your VPN configurations and keys to avoid losing them in case a server fails.

Conclusion

Hosting a private VPN on a VPS provides unmatched control and privacy compared to using a commercial VPN service. With your own server, you fully manage the security measures, avoid data logging, and bypass geo-restrictions without using third-party services.

Remember to keep everything updated and secure (check for updates and monitor server logs) for continued protection of your online activities.
