At its heart, v2rayNG is not an independent virtual private network (VPN) service, but rather a graphical user interface (GUI) designed to operate on top of advanced cores. It natively supports both the and the v2fly core . These cores are part of a larger ecosystem designed to route network traffic securely. Unlike traditional VPNs that often use easily identifiable signatures, the protocols handled by v2rayNG—such as VMess, VLESS, Shadowsocks, and Trojan—utilize advanced obfuscation techniques. This makes the encrypted traffic look like standard, harmless web browsing (such as regular HTTPS traffic), making it incredibly difficult for automated firewall systems to detect and block. Functionality and Customization
For advanced users, the application opens up a massive sandbox of customization. It allows for:
Users can split their traffic so that local apps bypass the proxy while blocked foreign sites go through the secure tunnel.
