!!! warning ""

QUIC, which is required by TUIC is not included by default, see [Installation](/#installation).

Fields

server

==Required==

The server address.

server_port

==Required==

The server port.

uuid

==Required==

TUIC user uuid

password

TUIC user password

congestion_control

QUIC congestion control algorithm

One of: cubic, new_reno, bbr

cubic is used by default.

udp_relay_mode

UDP packet relay mode

Mode Description
native native UDP characteristics
quic lossless UDP relay using QUIC streams, additional overhead is introduced

native is used by default.

Conflict with udp_over_stream.

udp_over_stream

This is the TUIC port of the UDP over TCP protocol, designed to provide a QUIC stream based UDP relay mode that TUIC does not provide. Since it is an add-on protocol, you will need to use sing-box or another program compatible with the protocol as a server.

This mode has no positive effect in a proper UDP proxy scenario and should only be applied to relay streaming UDP traffic (basically QUIC streams).

Conflict with udp_relay_mode.

network

Enabled network

One of tcp udp.

Both is enabled by default.

tls

==Required==

TLS configuration, see TLS.

Dial Fields

See Dial Fields for details.
