+
+### Listen Fields
+
+#### listen
+
+==Required==
+
+Listen address.
+
+#### listen_port
+
+==Required==
+
+Listen port.
+
+#### 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.
+
+### Hysteria Fields
+
+#### up, down
+
+==Required==
+
+Format: `[Integer] [Unit]` e.g. `100 Mbps, 640 KBps, 2 Gbps`
+
+Supported units (case sensitive, b = bits, B = bytes, 8b=1B):
+
+    bps (bits per second)
+    Bps (bytes per second)
+    Kbps (kilobits per second)
+    KBps (kilobytes per second)
+    Mbps (megabits per second)
+    MBps (megabytes per second)
+    Gbps (gigabits per second)
+    GBps (gigabytes per second)
+    Tbps (terabits per second)
+    TBps (terabytes per second)
+
+#### up_mbps, down_mbps
+
+==Required==
+
+`up, down` in Mbps.
+
+#### obfs
+
+Obfuscated password.
+
+#### auth
+
+Authentication password, in base64.
+
+#### auth_str
+
+Authentication password.
+
+#### recv_window_conn
+
+The QUIC stream-level flow control window for receiving data.
+
+`15728640 (15 MB/s)` will be used if empty.
+
+#### recv_window_client
+
+The QUIC connection-level flow control window for receiving data.
+
+`67108864 (64 MB/s)` will be used if empty.
+
+#### max_conn_client
+
+The maximum number of QUIC concurrent bidirectional streams that a peer is allowed to open.
+
+`1024` will be used if empty.
+
+#### disable_mtu_discovery
+
+Disables Path MTU Discovery (RFC 8899). Packets will then be at most 1252 (IPv4) / 1232 (IPv6) bytes in size.
+
+Force enabled on for systems other than Linux and Windows (according to upstream).
+
+#### tls
+
+==Required==
+
+TLS configuration, see [TLS inbound structure](/configuration/shared/tls/#inbound-structure).
