Introductory Theory Modern anti-fraud systems are becoming increasingly persistent in identifying your real IP address or detecting the use of tools designed to hide it. Even if you’re using a proxy or VPN, they can determine that you’re not a “real” user based on various parameters.

One of the most common detection mechanisms is WebRTC - a technology capable of sending requests outside of the proxy path, thereby exposing your real IP address if WebRTC is not blocked at the browser level.

The solution? Two-way support for the UDP protocol - both on the proxy side and within software tools.

The inspiration for this approach came from an article by Zl0yTeam. The Article «Зачем нужны прокси с UDP и при чём тут WebRTC». It significantly helped us understand how WebRTC works and inspired us to write this article!
