# General settings for router

#### ⚙️ Set up Router – Global Proxy/VPN + WebRTC Protection

***

**🔢 IP LAN Field**

* This shows the local IP address of the router, e.g. `192.168.12.1`
* Normally, you don’t need to change this unless you're customizing the internal network. Leave it as default for most users.

***

**🛡️ WebRTC Interference Mode**

* When enabled, this mode helps **prevent WebRTC leaks**.
* **What is WebRTC?**\
  WebRTC is a browser-based technology used for video/audio communication (Zoom, Google Meet, etc.). But it can **leak your real IP address**, even when you're using a proxy or VPN.
* **Why enable this?**\
  If you’re using proxies to hide your IP and identity (e.g. for farming accounts), **you should enable this option** to prevent accidental exposure through the browser.

📌 **Recommendation:**\
✅ Tick this option **if you are using Chrome or any browser** to avoid leaking your real IP address.

***

**✅ To apply settings:**

1. (Optional) Change the LAN IP if needed
2. ✅ Tick **"WebRTC Interference Mode"** to activate protection
3. Click **Apply** to confirm

Once applied, the proxy/VPN setting will affect all devices connected to the GenRouter network.
