TUIC

The example uses TUIC v5. For v4, delete uuid and password and use token: YOUR_TOKEN. Never keep both authentication forms.

Node example

Merge this node into the configuration’s proxies list. Replace example addresses, identities, and credentials. If you rename Node, update group references too.

    type: tuic
    server: proxy.example.com
    port: 443
    uuid: 00000000-0000-4000-8000-000000000001
    password: YOUR_PASSWORD
    sni: proxy.example.com
    alpn: [h3]
    udp-relay-mode: native
