For decades, private traffic hid inside a special protocol. IPsec, OpenVPN, and WireGuard still do that: they punch an encrypted L2/L3 tunnel across the public path, then stuff TCP, UDP, SCTP, or RTP inside it. Middleboxes learned the silhouette.

SCTP (Stream Control Transmission Protocol)
SCTP (Stream Control Transmission Protocol) is a robust, message-oriented transport layer protocol designed for mission-critical applications that demand reliability and fault tolerance. Originally developed for telephony signaling—specifically for SS7 (Signaling System No. 7) over IP—SCTP has evolved into an essential protocol for modern telecommunications, WebRTC data channels, and high-availability networks. Its unique capabilities make it … Continue reading SCTP (Stream Control Transmission Protocol)
