 !!! warning ""
    QUIC, which is required by hysteria is not included by default, see [Installation](/#Installation).
 ### 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).

 #### network
 Enabled network
 One of `tcp` `udp`.
 Both is enabled by default.
 ### 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.
 #### 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`.
