Outbound Proxies
Outbound connections are used for sending data and can use any of the available protocols listed in outbound protocols.
OutboundObject
The OutboundObject corresponds to a sub-element of the outbounds item in the configuration file.
::: tip The first element in the list serves as the main outbound. When there is no match or no successful match for the routing, the traffic is sent out by the main outbound. :::
{
"outbounds": [
{
"sendThrough": "0.0.0.0",
"protocol": "protocol name",
"settings": {},
"tag": "identifier",
"streamSettings": {},
"proxySettings": {
"tag": "another-outbound-tag"
},
"mux": {}
}
]
}
sendThrough: address
The IP address used to send data. It is effective when the host has multiple IP addresses, and the default value is "0.0.0.0".
protocol: string
The name of the connection protocol. The optional protocol types can be found in outbound protocols.
settings: OutboundConfigurationObject
The specific configuration content varies depending on the protocol. See OutboundConfigurationObject in each protocol for details.
tag: string
The identifier of this outbound connection, used to locate this connection in other configurations.
::: danger
When it is not empty, its value must be unique among all tags.
:::
streamSettings: StreamSettingsObject
The underlying transport method is the way the current Xray node and other nodes are docked.
proxySettings: ProxySettingsObject
The outbound proxy configuration. When the outbound proxy takes effect, the streamSettings of this outbound will not work.
mux: MuxObject
Specific configuration related to Mux.
ProxySettingsObject
{
"tag": "another-outbound-tag"
}
tag: string
When specifying the identifier of another outbound, data emitted by this outbound will be forwarded to the specified outbound.
::: danger This forwarding method does not go through the underlying transport. If you need to use forwarding that supports the underlying transport, please use SockOpt.dialerProxy. :::
::: danger This option is incompatible with SockOpt.dialerProxy. :::
::: tip Compatible with v2fly/v2ray-core's configuration transportLayer. :::
MuxObject
The Mux function distributes the data of multiple TCP connections on a single TCP connection. For implementation details, see Mux.Cool. Mux is designed to reduce the latency of TCP handshake, not to increase the throughput of connections. Using Mux for watching videos, downloading, or speed testing usually has negative effects. Mux only needs to be enabled on the client side, and the server side automatically adapts.
MuxObject corresponds to the mux item in OutboundObject.
{
"enabled": false,
"concurrency": 8
}
enabled: true | false
Whether to enable Mux forwarding requests, default is false.
concurrency: number
Maximum concurrent connections. Minimum value is 1, maximum value is 1024, default is 8.
This value represents the maximum number of Mux connections that can be carried on a TCP connection. For example, when concurrency=8 is set, if the client sends 8 TCP requests, Xray will only send one actual TCP connection, and all 8 requests from the client will be transmitted through this TCP connection.
::: tip
When filling in a negative number, such as -1, the mux module is not loaded.
