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

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`socks` inbound is a http server.

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.

Listen Fields

listen

==Required==

Listen address.

listen_port

==Required==

Listen port.

sniff

Enable sniffing.

See 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.
