Proxy nodes are written as an array.

name

Required, proxy name. Must be unique.

type

Required, proxy node type.

server

Required, proxy node server (domain/IP).

port

Required, proxy node port.

ip-version

IP version used by outbound proxy connections. If the proxy is not direct, this affects which IP address is used when server is a domain name.

Available values: dual/ipv4/ipv6/ipv4-prefer/ipv6-prefer. Default: dual.

• ipv4: use IPv4 only.
• ipv6: use IPv6 only.
• ipv4-prefer: prefer IPv4. For TCP, dual-stack resolution is performed and connections are raced, but IPv4 connections are preferred. For UDP, dual-stack resolution is performed and the first IPv4 result is used.
• ipv6-prefer: prefer IPv6. For TCP, dual-stack resolution is performed and connections are raced, but IPv6 connections are preferred. For UDP, dual-stack resolution is performed and the first IPv6 result is used.

udp

Whether to allow UDP through the proxy. Default: false.

Note

This option is enabled by default for UDP-based protocols such as TUIC, and for the direct and dns types.

interface-name

Specifies the interface bound by the node. Connections are initiated from this interface.

routing-mark

Routing mark attached when the node initiates connections.

tfo

Enables TCP Fast Open. Only effective for the TCP protocol.

mptcp

Enables TCP Multi Path. Only effective for the TCP protocol.

dialer-proxy

Specifies that the current proxies entry establishes network connections through dialer-proxy. The value can be the name of a proxy group or an outbound proxy. See the dialer-proxy documentation for usage.

udp-443 👻

allow (default) or reject. With reject, UDP traffic to port 443 (QUIC) that a rule sends through this proxy goes into REJECT, so browsers fall back to TCP. quic is an alias. Every proxy type takes it. See udp-443.

mux.cool 👻

Xray-compatible multiplexing (Mux.Cool, XUDP), a block with enabled, max-carriers, max-concurrency, max-connections, xudp-concurrency and xudp-proxy-udp443. Cannot be enabled together with smux. See mux.cool.

smux

sing-mux, only for protocols using TCP transport.

smux.enabled

Whether to enable multiplexing.

smux.protocol

Multiplexing protocol. The following protocols are supported. Default: h2mux.

Protocol	Description
smux	<https://github.com/xtaci/smux>
yamux	<https://github.com/hashicorp/yamux>
h2mux	<https://golang.org/x/net/http2>

smux.max-connections

Maximum number of connections.

Conflicts with max-streams.

smux.min-streams

Minimum number of multiplexed streams in a connection before opening a new connection.

Conflicts with max-streams.

smux.max-streams

Maximum number of multiplexed streams in a connection before opening a new connection.

Conflicts with max-connections and min-streams.

smux.statistic

Controls whether the underlying connection is displayed in the dashboard, making it easier to interrupt the underlying connection.

smux.only-tcp

Allows TCP only. If set to true, smux settings do not take effect for UDP; UDP connections use the node’s default UDP transport directly.

smux.padding

Enables padding.

smux.brutal-opts

TCP Brutal settings.

smux.brutal-opts.enabled

Enables the TCP Brutal congestion control algorithm.

smux.brutal-opts.up/down

Upload and download bandwidth. Defaults to Mbps.
