Blocks & Bypassing

Why are popular protocols like OpenVPN and WireGuard blocked, and what is obfuscation?

FILTERING SYSTEMS RECOGNIZE PROTOCOL SIGNATURES, WHILE OBFUSCATION DISGUISES THEM AS REGULAR WEB TRAFFIC.
Modern DPI inspection systems analyze packet structures and flag standard service headers of secure connections. Obfuscation technologies wrap the tunnel into regular HTTPS web traffic format, rendering it invisible to filters.

How Standard Protocols Are Detected

Deep Packet Inspection (DPI) equipment evaluates not the contents of the encrypted message, but its technical fingerprint, metadata size, and ports used. OpenVPN and WireGuard feature distinct session start markers, allowing ISP automation to instantly drop network packets.
