Best Free Ways to Build Your Own VPN Without Trusting Big Providers

In an era where privacy concerns are at an all-time high, many users are questioning whether they can trust commercial VPN providers with their data. The solution? Building your own VPN server. This comprehensive guide will walk you through multiple free methods to create your own private VPN.

Why Build Your Own VPN?

Commercial VPN providers promise privacy and security, but you're essentially trusting them with all your internet traffic. While many reputable providers have undergone independent audits, there's always an element of trust involved. When you run your own VPN server, you have complete control over:

• Logging policies - You decide what gets logged (ideally nothing)
• Server location - Choose exactly where your exit point is
• Encryption settings - Configure security to your exact specifications
• Access control - Only you and people you trust can use it

Method 1: Oracle Cloud Free Tier (Recommended)

Oracle Cloud offers a genuinely free tier that includes two AMD-based compute instances that never expire. This makes it perfect for hosting a personal VPN.

Step-by-Step Setup:

1. Create an Oracle Cloud account at cloud.oracle.com
2. Launch a compute instance - Choose Ubuntu 22.04 LTS
3. Configure networking - Open UDP port 51820 for WireGuard
4. SSH into your instance and run the WireGuard installation script

WireGuard Installation Script:

curl -O https://raw.githubusercontent.com/angristan/wireguard-install/master/wireguard-install.sh
chmod +x wireguard-install.sh
sudo ./wireguard-install.sh

The script will guide you through the setup process and generate client configuration files automatically.

Method 2: AWS Free Tier

Amazon Web Services offers a 12-month free tier that includes 750 hours of t2.micro instances per month. While not permanently free like Oracle, it's an excellent option for getting started.

Key Considerations:

• Monitor your usage carefully to avoid charges
• Data transfer is limited to 15GB outbound per month
• Set up billing alerts to prevent surprise charges
• Consider using Lightsail ($3.50/month) after the free tier ends

Method 3: Google Cloud Platform

Google Cloud offers $300 in free credits for new users, valid for 90 days. Additionally, their f1-micro instances in certain regions are part of the "Always Free" tier.

Setting Up on GCP:

1. Create a GCP account and enable billing (required even for free tier)
2. Create an f1-micro instance in us-west1, us-central1, or us-east1
3. Configure firewall rules for your VPN protocol
4. Install and configure WireGuard or OpenVPN

Method 4: Self-Hosted at Home

If you have a reliable internet connection with a static IP (or dynamic DNS), you can run a VPN server on a Raspberry Pi or old computer.

Advantages:

• Complete physical control over the hardware
• No third-party involvement whatsoever
• Can handle many simultaneous connections
• One-time hardware cost only

Disadvantages:

• Exposes your home IP address
• Relies on your home internet uptime
• Your ISP can see the VPN traffic (though not its contents)
• Doesn't help with geo-restriction bypassing

Choosing Between WireGuard and OpenVPN

For self-hosted VPNs, WireGuard is generally the better choice:

Security Hardening Tips

Once your VPN is running, follow these security best practices:

1. Enable Automatic Updates

sudo apt install unattended-upgrades
sudo dpkg-reconfigure -plow unattended-upgrades

2. Configure a Firewall

sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow 22/tcp
sudo ufw allow 51820/udp
sudo ufw enable

3. Disable Root SSH Login

Edit /etc/ssh/sshd_config and set:

PermitRootLogin no
PasswordAuthentication no

4. Set Up Fail2Ban

sudo apt install fail2ban
sudo systemctl enable fail2ban

Performance Optimization

To get the best performance from your self-hosted VPN:

• Choose a nearby server location - Latency significantly impacts perceived speed
• Use WireGuard - It's significantly faster than OpenVPN
• Enable BBR congestion control - Improves throughput on Linux servers
• Tune MTU settings - Default is usually fine, but testing can help

Enable BBR:

echo "net.core.default_qdisc=fq" | sudo tee -a /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p

Maintaining Your VPN

A self-hosted VPN requires some ongoing maintenance:

• Weekly: Check server is running and accessible
• Monthly: Review logs for suspicious activity
• Quarterly: Update server software and rotate keys if needed
• Yearly: Review security practices and update configurations

When Self-Hosting Isn't the Right Choice

Self-hosting isn't for everyone. Consider a commercial VPN if:

• You need servers in many different countries
• You want streaming service compatibility
• You lack technical skills or time for maintenance
• You need 24/7 customer support
• You want additional features like ad blocking or malware protection

Conclusion

Building your own VPN is an excellent way to take control of your privacy. With free cloud resources from Oracle, AWS, or Google, you can have a fully functional VPN server running in under an hour. While it requires more technical knowledge than using a commercial service, the privacy benefits and educational value make it worthwhile for many users.

Remember: no VPN solution is perfect. A self-hosted VPN doesn't make you anonymous online, but it does ensure that no third party is handling your traffic. Combined with good security practices, it's a powerful privacy tool.
