+## Protocol Sniffing
+
+Due to factors such as the client's inbound (e.g., TUN mode) and configuration, Hysteria sometimes can't get the domain name of the destination address and only gets the IP. But the IP the client and server get for the same domain might be different, and the ACL's domain rules can't match IP requests. By enabling protocol sniffing, the server can use DPI to extract the domain name from the connection (for supported protocols) and convert the IP request to a domain one.
+
+Currently supported protocols are:
+
+- HTTP - Host in the header
+- TLS (HTTPS) - SNI
+- QUIC (HTTP/3) - SNI
+
+```yaml
+sniff:
+  enable: true # (1)!
+  timeout: 2s # (2)!
+  rewriteDomain: false # (3)!
+  tcpPorts: 80,443,8000-9000 # (4)!
+  udpPorts: all # (5)!
+```
+
+1. Whether to enable protocol sniffing.
+2. Sniffing timeout. If the protocol/domain cannot be determined within this time, the original address will be used to initiate the connection.
+3. Whether to rewrite requests that are already in domain name form. If enabled, requests with the target address already in domain name form will still be sniffed.
+4. List of TCP ports. Only TCP requests on these ports will be sniffed.
+5. List of UDP ports. Only UDP requests on these ports will be sniffed.
+
+> **Note:** If no port list is provided, all ports will be sniffed by default. The format of the port list is the same as port hopping, supporting multiple single ports and port ranges (inclusive) separated by commas.
+
 ## ACL
 
 ACL, often used in combination with outbounds, is a very powerful feature of the Hysteria server that allows you to customize the way client's requests are handled. For example, you can use ACL to block certain addresses, or to use different outbounds for different websites.

 如果省略，Hysteria 将使用系统默认的 DNS 服务器。
 
+## 协议嗅探 (Sniff)
+
+由于客户端连接入站的方式（如 TUN 模式）及配置等因素，Hysteria 有时无法获取到域名形式的目标地址，只能拿到解析后的 IP。但对于相同域名，客户端和服务端解析出的 IP 可能不同，且 ACL 的域名规则无法匹配 IP 请求。开启协议嗅探后，服务端能通过 DPI 从上层协议中获取目标域名，将 IP 请求转换为域名请求。
+
+目前支持的协议有：
+
+- HTTP - Host 字段
+- TLS (HTTPS) - SNI
+- QUIC (HTTP/3) - SNI
+
+```yaml
+sniff:
+  enable: true # (1)!
+  timeout: 2s # (2)!
+  rewriteDomain: false # (3)!
+  tcpPorts: 80,443,8000-9000 # (4)!
+  udpPorts: all # (5)!
+```
+
+1. 是否启用协议嗅探。
+2. 嗅探超时时间。如果超过这个时间仍然无法确定协议/获取域名，将使用原地址发起连接。
+3. 是否重写已经是域名的请求。如果启用，对于目标地址已经是域名的请求，仍会进行嗅探。
+4. TCP 端口列表。只有这些端口的 TCP 请求会被嗅探。
+5. UDP 端口列表。只有这些端口的 UDP 请求会被嗅探。
+
+> **注意：** 如果不提供端口列表，默认所有端口都会被嗅探。端口列表中的端口格式与端口跳跃相同，支持逗号分隔的多个单端口和端口范围（闭区间）。
+
 ## ACL
 
 ACL 是 Hysteria 服务端中一个非常强大的功能，可以用来自定义处理客户端请求的方式，往往配合出站规则（outbounds）使用。例如，可以使用 ACL 来屏蔽某些地址，或者针对不同网站使用不同的出口。
