WebRTC 泄漏——是什么以及如何防范

3 分钟 阅读·更新于 May 20, 2026

即使连接了 VPN，WebRTC 仍可能暴露你的真实 IP。本文介绍如何阻止它。

WebRTC is a browser technology for video calls and real-time communication. It can bypass your VPN and expose your real IP address to websites — even when connected to a VPN.

Test for a WebRTC leak

  1. 1Connect to HorizonVPN
  2. 2Visit ipleak.net
  3. 3Look at the WebRTC section — if it shows your real IP (not the VPN IP), you have a leak

Fix by browser

  • HorizonVPN app: Enable WebRTC Leak Protection in Settings → Privacy
  • Firefox: visit about:config → set media.peerconnection.enabled to false
  • Chrome: install the "WebRTC Leak Prevent" extension
  • Brave: Settings → Privacy → WebRTC IP Handling Policy → Disable non-proxied UDP
