<br>
<div align=justify>The FTP service can work in two different ways:

'''1'''. active mode;

'''2'''. passive mode

Basically, the difference is that in active mode, both the server and the client will be required to open up ports to listen for incoming traffic. In  Active FTP session connection is established by the FTP server to the client. This will cause problems if you are behind a firewall. In most cases your FTP client will cause the bult-in firewall to pop up a warning informing you that the client is trying to open an inbound connection.

Some of the FTP clients have an option to enable passive mode for all FTP transfers. When using passive FTP, the client tells the server to listen for a data connection initiated by the client. The FTP server tells the client which IP, port it will listen on.

By default all browsers are configured to work in passive mode when used as FTP clients. If you are behind a firewall, it's better to use the passive FTP mode to connect to an external FTP server.

'''Note:''' Passive FTP is considered to be more secure than active FTP as it ensures that all connections are initiated by the client.</div>
