### Fields

#### server

==Required==

The server address.

#### server_port

==Required==

The server port.

#### 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

The QUIC connection-level flow control window for receiving data.

`67108864 (64 MB/s)` 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.
