-### Clash API 字段
-
-!!! error ""
-
-    默认安装不包含 Clash API，参阅 [安装](/zh/#_2)。
-
-#### external_controller
-
-RESTful web API 监听地址。如果为空，则禁用 Clash API。
-
-#### external_ui
-
-到静态网页资源目录的相对路径或绝对路径。sing-box 会在 `http://{{external-controller}}/ui` 下提供它。
-
-#### secret
-
-RESTful API 的密钥（可选）
-通过指定 HTTP 标头 `Authorization: Bearer ${secret}` 进行身份验证
-如果 RESTful API 正在监听 0.0.0.0，请始终设置一个密钥。
-
-#### direct_io
-
-允许像 splice 这样的没有实时流量报告的无损中继。
-
-#### default_mode
-
-Clash 中的默认模式，默认使用 `rule`。
-
-此设置没有直接影响，但可以通过 `clash_mode` 规则项在路由和 DNS 规则中使用。
-
-#### store_selected
-
-!!! note ""
-
-    必须为目标出站设置标签。
-
-将 `Selector` 中出站的选定的目标出站存储在缓存文件中。
-
-#### cache_file
-
-缓存文件路径，默认使用`cache.db`。
-
-### V2Ray API 字段

-    默认安装不包含 V2Ray API，参阅 [安装](/zh/#_2)。
-
-#### listen
-
-gRPC API 监听地址。如果为空，则禁用 V2Ray API。
-
-#### stats
-
-流量统计服务设置。
-
-#### stats.enabled
-
-启用统计服务。
-
-#### stats.direct_io
-
-允许像 splice 这样的没有实时流量报告的无损中继。
-
-#### stats.inbounds

 ### Listen Fields
 
-See [Listen Fields](/configuration/shared/listen) for details.
+#### listen
 
-### Fields
+==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.
+
+#### udp_timeout
+
+UDP NAT expiration time in seconds, default is 300 (5 minutes).
+
