Architecture and ISP Visibility
WireGuard transmits data in characteristic fixed UDP headers, allowing Deep Packet Inspection (DPI) systems to instantly detect and block the connection. VLESS operates without unnecessary internal encryption (delegating it to external TLS), and when combined with XTLS-Reality, disguises traffic as a request to a legitimate, popular website.
What to Choose for Specific Tasks
- Choose WireGuard for basic privacy, streaming, and gaming on unblocked channels
- Switch to VLESS (Xray) on networks with strict protocol blocks
- Set up fallback to Reality if standard ports and protocols stop connecting
