Why Old Protocols Can No Longer Cope
Deep Packet Inspection (DPI) systems have learned to accurately recognize OpenVPN, WireGuard, and IKEv2 service headers even without decrypting data. For stable operation, traffic must look like regular secure web browsing.
Reliable Modern Technologies
- VLESS with Reality: mimics regular TLS connections to popular foreign websites, making traffic indistinguishable from normal web surfing.
- Hysteria2: a UDP-based protocol optimized for unstable networks and resistant to aggressive filtering.
- Shadowsocks with obfuscation: disguises data packets as random noise or a standard HTTPS stream.
