Outbound

An outbound is how traffic leaves: through a proxy server, straight to the destination, or through a group that picks another outbound. Routing decides which outbound a request takes; without a routing section, every request takes the first. Blocking is a routing action, not an outbound.

Protocols

Type	Format	Carries
`socks5`	SOCKS5	TCP
`http`	HTTP	TCP
`trojan`	Trojan	TCP and UDP
`vless`	VLESS	TCP and UDP

Built in, made by core rather than a module:

Type	Format	Carries
`freedom`	Freedom	TCP and UDP, straight to each destination
`urltest`	URLTest, see groups	what every member carries
`fallback`	Fallback, see groups	what every member carries
`selector`	Selector, see groups	what every member carries

freedom and the groups take only some of the keys below; their pages say which.

Fields

`tag`

stringRequired

A name unique among outbounds, used by routing, DNS servers, groups and statistics.

`server`

addressRequired

The proxy server, an IP or a domain. tls sends a domain as its SNI, and ws and httpupgrade as the Host, unless they set their own.

`server_port`

integerRequired

The proxy server's port.

`transport`

list of transportsRequired

The transport stack that reaches the server.

`protocol`

objectRequired

type and settings of one of the protocols.

`dns_server`

stringDefault: the DNS rules' choice

The tag of the DNS server that resolves server when it is a domain.

`muxcool`

objectvless
