Fields

detour

The tag of the upstream outbound.

If enabled, all other fields will be ignored.

bind_interface

The network interface to bind to.

inet4_bind_address

The IPv4 address to bind to.

inet6_bind_address

The IPv6 address to bind to.

routing_mark

!!! quote ""

Only supported on Linux.

Set netfilter routing mark.

reuse_addr

Reuse listener address.

tcp_fast_open

Enable TCP Fast Open.

tcp_multi_path

!!! warning ""

Go 1.21 required.

Enable TCP Multi Path.

udp_fragment

Enable UDP fragmentation.

connect_timeout

Connect timeout, in golang's Duration format.

A duration string is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as "300ms", "-1.5h" or "2h45m". Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h".

domain_strategy

Available values: prefer_ipv4, prefer_ipv6, ipv4_only, ipv6_only.

If set, the requested domain name will be resolved to IP before connect.

Outbound	Effected domains	Fallback Value
`direct`	Domain in request	Take `inbound.domain_strategy` if not set
others	Domain in server address	/

network_strategy

!!! question "Since sing-box 1.11.0"

!!! quote ""

Only supported in graphical clients on Android and iOS with `auto_detect_interface` enabled.

Strategy for selecting network interfaces.

Available values:

default (default): Connect to the default interface.
fallback: Try all other interfaces when timeout.
hybrid: Connect to all interfaces concurrently and choose the fastest one.
wifi: Prioritize WIFI, but try all other interfaces when unavailable or timeout.
cellular: Prioritize Cellular, but try all other interfaces when unavailable or timeout.
ethernet: Prioritize Ethernet, but try all other interfaces when unavailable or timeout.
wifi_only: Connect to WIFI only.
cellular_only: Connect to Cellular only.
ethernet_only: Connect to Ethernet only.

For fallback strategies, when preferred interfaces fails or times out, it will enter a 15s fast fallback state (upgraded to hybrid), and exit immediately if recovers.

Conflicts with bind_interface, inet4_bind_address and inet6_bind_address.

fallback_delay

The length of time to wait before spawning a RFC 6555 Fast Fallback connection.

For domain_strategy, is the amount of time to wait for connection to succeed before assuming that IPv4/IPv6 is misconfigured and falling back to other type of addresses.

For network_strategy, is the amount of time to wait for connection to succeed before falling back to other interfaces.

Only take effect when domain_strategy or network_strategy is set.

300ms is used by default.
