@ -121,6 +121,9 @@ The configuration file contains the following sections:
- `apply_proxy_config`, boolean. If enabled the common proxy configuration, if any, will be applied. Please note that we expect the proxy header on control and data connections. Default `true`.
- `tls_mode`, integer. 0 means accept both cleartext and encrypted sessions. 1 means TLS is required for both control and data connection. 2 means implicit TLS. Do not enable this blindly, please check that a proper TLS config is in place if you set `tls_mode` is different from 0.
- `force_passive_ip`, ip address. External IP address to expose for passive connections. Leavy empty to autodetect. If not empty, it must be a valid IPv4 address. Defaut: "".
- `passive_ip_overrides`, list of struct that allows to return a different passive ip based on the client IP address. Each struct has the following fields:
- `networks`, list of strings. Each string must define a network in CIDR notation, for example 192.168.1.0/24.
- `ip`, string. Passive IP to return if the client IP address belongs to the defined networks. Empty means autodetect.
- `client_auth_type`, integer. Set to `1` to require a client certificate and verify it. Set to `2` to request a client certificate during the TLS handshake and verify it if given, in this mode the client is allowed not to send a certificate. At least one certification authority must be defined in order to verify client certificates. If no certification authority is defined, this setting is ignored. Default: 0.
- `tls_cipher_suites`, list of strings. List of supported cipher suites for TLS version 1.2. If empty, a default list of secure cipher suites is used, with a preference order based on hardware performance. Note that TLS 1.3 ciphersuites are not configurable. The supported ciphersuites names are defined [here](https://github.com/golang/go/blob/master/src/crypto/tls/cipher_suites.go#L52). Any invalid name will be silently ignored. The order matters, the ciphers listed first will be the preferred ones. Default: empty.
- `passive_connections_security`, integer. Defines the security checks for passive data connections. Set to `0` to require matching peer IP addresses of control and data connection. Set to `1` to disable any checks. Please note that if you run the FTP service behind a proxy you must enable the proxy protocol for control and data connections. Default: `0`.
