The default value is 0, which does not limit the transfer rate.
• max_clients — Specifies the maximum number of simultaneous clients allowed to connect to the
server when it is running in standalone mode. Any additional client connections would result in an
error message.
The default value is 0, which does not limit connections.
• max_per_ip — Specifies the maximum of clients allowed to connected from the same source IP
address.
The default value is 0, which does not limit connections.
• pasv_address — Specifies the IP address for the public facing IP address of the server for servers
behind Network Address Translation (NAT) firewalls. This enables vsftpd to hand out the correct
return address for passive mode connections.
There is no default value for this directive.
• pasv_enable — When enabled, passive mode connects are allowed.
The default value is YES.
• pasv_max_port — Specifies the highest possible port sent to the FTP clients for passive mode
connections. This setting is used to limit the port range so that firewall rules are easier to create.
The default value is 0, which does not limit the highest passive port range. The value must not
exceed 65535.
• pasv_min_port — Specifies the lowest possible port sent to the FTP clients for passive mode
connections. This setting is used to limit the port range so that firewall rules are easier to create.
The default value is 0, which does not limit the lowest passive port range. The value must not be
lower 1024.
• pasv_promiscuous — When enabled, data connections are not checked to make sure they are
originating from the same IP address. This setting is only useful for certain types of tunneling.
Caution
Do not enable this option unless absolutely necessary as it disables an important
security feature which verifies that passive mode connections originate from the same
IP address as the control connection that initiates the data transfer.
The default value is NO.
• port_enable — When enabled, active mode connects are allowed.
The default value is YES.
