In the realm of online gaming, privacy and security are paramount, yet often at odds with the stringent anti-cheat mechanisms designed to keep the playing field level. Today, we’re diving deep into the art of setting up a Stealth VPN specifically tailored for gamers. This isn’t your everyday VPN setup; it’s about creating an undetectable line of defense against prying eyes, all while maintaining your standing in anti-cheat communities. Let’s embark on this thrilling journey of securing our gaming sessions with the sophistication of a Stealth VPN, using OpenVPN and stunnel.

Why Stealth VPN?

In an era where digital surveillance is rampant, a conventional VPN might not always fly under the radar, especially with games that use sophisticated anti-cheat software. These systems can sometimes flag VPN traffic, mistakenly identifying it as a potential cheat tool. Enter Stealth VPN, a technique that cloaks the VPN traffic, making it appear as regular HTTPS traffic and thus, bypassing the anti-cheat radars.

Setting Up OpenVPN with stunnel

Prerequisites

• A VPS (Virtual Private Server) with root access
• OpenVPN installed on both your gaming machine and VPS
• stunnel installed on both your gaming machine and VPS

Step 1: Configuring OpenVPN

First, set up OpenVPN on your VPS. This isn’t a tutorial on OpenVPN basics, so I’ll assume you’re familiar with setting it up. Once OpenVPN is running, note the port it’s listening on; we’ll need this later.

1

sudo systemctl start openvpn@server

Step 2: Installing and Configuring stunnel

Install stunnel on both your VPS and your local machine. The magic of stunnel is in its ability to encrypt and tunnel any TCP connection, making our OpenVPN traffic invisible to most deep packet inspection (DPI).

On the VPS:

1. Generate an SSL certificate for stunnel.

1

openssl req -new -x509 -days 3650 -nodes -out /etc/stunnel/stunnel.pem -keyout /etc/stunnel/stunnel.pem

2. Configure stunnel to listen for incoming OpenVPN connections and tunnel them. Edit the stunnel configuration file (/etc/stunnel/stunnel.conf) and add:

1
2
3
4

[openvpn]
client = no
accept = 443
connect = 127.0.0.1:YOUR_OPENVPN_PORT

Replace YOUR_OPENVPN_PORT with the actual port OpenVPN is listening on. The accept directive tells stunnel to listen on port 443, the standard HTTPS port, making our traffic indistinguishable from regular web traffic.

3. Start stunnel on your VPS.

1

sudo systemctl start stunnel4

On Your Local Machine:

1. Configure stunnel similarly, but in reverse. The goal is to connect to your VPS’s stunnel from your machine, which then forwards the connection to OpenVPN. Your local stunnel configuration might look like this:

1
2
3
4

[openvpn]
client = yes
accept = 127.0.0.1:1194
connect = YOUR_VPS_IP:443

2. Start stunnel on your local machine.

1

sudo systemctl start stunnel4

Step 3: Connecting to OpenVPN through stunnel

With both stunnel instances running, connect to OpenVPN as you normally would, but instead of connecting directly to your VPS, connect to the local stunnel instance. This routes your OpenVPN traffic through stunnel, effectively cloaking it.

1

sudo openvpn --config client.ovpn

Replace client.ovpn with your OpenVPN client configuration file, ensuring it’s set to connect to 127.0.0.1:1194, which is where your local stunnel is listening.

Troubleshooting

• Connection Issues: Ensure both OpenVPN and stunnel are running and configured correctly. Use netstat or ss to verify they’re listening on the expected ports.
• Performance: Stealth VPNs can introduce additional latency. Optimize OpenVPN and stunnel settings for performance, like adjusting the MTU or using faster encryption algorithms.
• Anti-Cheat Detection: While our setup is designed to be undetectable, anti-cheat systems evolve. Keep your stunnel and OpenVPN software up to date to leverage the latest obfuscation techniques.

Next Steps

• Experiment with different stunnel encryption options to find the perfect balance between security and performance.
• Explore other VPN protocols that might offer better performance or compatibility with your gaming needs.
• Engage with the community. Share your findings and learn from others who’ve walked this path.

Conclusion

The road to gaming privacy is fraught with challenges, but with tools like OpenVPN and stunnel, we can navigate it with confidence. This setup not only secures your connection but does so in a way that keeps you in the clear with anti-cheat systems. Remember, the key to success in this endeavor is continuous learning and adaptation. Happy gaming, and stay stealthy!
