Controls whether to direct the server into passive mode. Recommended if behind a firewall.
This property controls whether to direct the server into passive mode. Many firewalls will not allow the FTP server to open a connection from outside to the higher ports where the 本製品 expects them. If Passive is set to TRUE, the 本製品 will use the PASV command instead of the PORT command and will thus direct the server into passive mode: connections are initiated only by the client.
