Bestes Zitat aus WebRTC and the STUN/TURN Mandate: Solving NAT and Firewall Issues
WebRTC is an iceberg where the peer-to-peer part is just the tip; beneath the surface, whitelisting STUN and TURN servers is a mandatory requirement to ensure your voice and video actually reach the other side.

The STUN/TURN mandate refers to the mandatory requirement of whitelisting these servers to ensure stable real-time communication. While WebRTC is often viewed as a simple peer-to-peer connection, firewalls and Network Address Translators (NATs) frequently block direct traffic. By using STUN and TURN servers, developers can bypass these security walls, which is essential for maintaining a reliable video or voice stream on platforms like BrowserStack.
Firewalls and Network Address Translators (NATs) are security measures designed to protect private networks by stopping unknown traffic from entering. However, these 'walls' often prevent two browsers from establishing the direct digital handshake required for WebRTC. When these security layers block the connection, users experience black screens or endless loading, making it necessary to use specialized server architecture to navigate through these network restrictions.
Peer-to-peer communication is difficult because the internet was not built for total directness; it was built with security barriers like NATs and firewalls. Although WebRTC is the backbone of modern real-time communication, these architectural hurdles often stop voice and video data from reaching the other side. To solve this, whitelisting STUN and TURN servers is required to facilitate the connection and ensure that private network security doesn't break the application's functionality.
