Select this option to indicate that Web Users are permitted to send the clear command channel (CCC) command during an encrypted FTP connection. If a Web User sends the CCC command, it terminates the encryption on the command channel and all subsequent FTP communication on the command channel will be transmitted in plain text. Please note that the encryption of the data channel is not affected by this setting. If unselected, the command channel will remain encrypted.
This setting is useful when
Managed File Transfer
is behind a NAT firewall that requires plain text commands for routing secondary FTPS data connections.
