Both is enabled by default. #### tls TLS configuration, see [TLS outbound structure](/configuration/shared/tls/#outbound). #### multiplex Multiplex configuration, see [Multiplex structure](/configuration/shared/multiplex). #### transport V2Ray Transport configuration, see [V2Ray Transport](/configuration/shared/v2ray-transport). ### Dial Fields #### detour The tag of the upstream outbound. Other dial fields will be ignored when enabled. #### bind_interface The network interface to bind to. #### bind_address The address to bind to. #### routing_mark !!! error "" Linux only The iptables routing mark. #### reuse_addr Reuse listener address. #### 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 One of `prefer_ipv4` `prefer_ipv6` `ipv4_only` `ipv6_only`. If set, the server domain name will be resolved to IP before connecting. `dns.strategy` will be used if empty. #### fallback_delay The length of time to wait before spawning a RFC 6555 Fast Fallback connection. That is, is the amount of time to wait for IPv6 to succeed before assuming that IPv6 is misconfigured and falling back to IPv4 if `prefer_ipv4` is set. If zero, a default delay of 300ms is used. Only take effect when `domain_strategy` is `prefer_ipv4` or `prefer_ipv6`.
