How do I configure the Sing-box client to bypass YouTube throttling and VLESS blocks?

IMPORT A JSON CONFIGURATION WITH ROUTING RULES AND ENABLE TUN MODE.

The versatile Sing-box core supports advanced camouflage protocols and flexible traffic sorting. Proper configuration lets you route video streams through a high-speed tunnel while maintaining direct access to local services.

Core-Level Selective Routing

Sing-box analyzes outbound packets using domain lists (geosite) and IP ranges (geoip). When accessing video streaming resources or blocked portals, the client automatically redirects traffic to the VLESS Reality outbound gateway, eliminating lag and speed drops on other tabs.

Launch and Optimization Steps

Load the ready-made JSON configuration via the Profiles tab in the app.
Enable the Tun Mode virtual network interface to intercept all system traffic.
Verify that the route rule for googlevideo domain zones exists in your config file.
Select the uTLS camouflage profile matching your desktop browser version.
