+### Listen Fields
+
+#### listen
+
+==Required==
+
+Listen address.
+
+#### listen_port
+
+==Required==
+
+Listen port.
+
+#### tcp_fast_open
+
+Enable tcp fast open for listener.
+
+#### sniff
+
+Enable sniffing.
+
+See [Sniff](/configuration/route/sniff/) for details.
+
+#### sniff_override_destination
+
+Override the connection destination address with the sniffed domain.
+
+If the domain name is invalid (like tor), this will not work.
+
+#### domain_strategy
+
+One of `prefer_ipv4` `prefer_ipv6` `ipv4_only` `ipv6_only`.
+
+If set, the requested domain name will be resolved to IP before routing.
+
+If `sniff_override_destination` is in effect, its value will be taken as a fallback.
+
+### Trojan Fields
+
+#### users
+
+Trojan users.
+
+#### tls

+
+### Dial Fields
+
+#### detour
+
+The tag of the upstream outbound.
+
+Other dial fields will be ignored when enabled.

+!!! 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`.
