The server responds with the PORT command. The source port is a random, high-numbered port. The client sends the PASV command to an FTP server on port 21. A passive FTP connection follows the following process:
This process is effective because most firewalls allow inbound traffic from sessions initiated by the client. When passive FTP is used, the client will initiate the connection to the server.
