Common fields

TLS fields

token

Required, user identifier for TUIC V4. Must not be written when using TUIC V5.

uuid

Required, unique user identifier for TUIC V5. Must not be written when using TUIC V4.

password

Required, user password for TUIC V5. Must not be written when using TUIC V4.

ip

Overrides the DNS lookup result for the address set in the server option.

heartbeat-interval

Interval for sending keepalive heartbeat packets, in milliseconds.

disable-sni

Whether to disable SNI (Server Name Indication) in the TLS handshake. SNI is used to host multiple HTTPS sites on the same IP address.

reduce-rtt

Whether to enable QUIC 0-RTT handshakes on the client. This can reduce connection setup time, but may increase replay attack risk.

request-timeout

Timeout for establishing a connection to the TUIC proxy server, in milliseconds.

udp-relay-mode

UDP packet relay mode. Available values: native/quic.

congestion-controller

Congestion control algorithm. Available values: cubic/new_reno/bbr.

max-udp-relay-packet-size

Maximum UDP relay packet size, in bytes.

fast-open

Whether to enable Fast Open, which can reduce connection setup time.

max-open-streams

Maximum number of open streams. Too many open streams may affect performance.
