What is the difference between Active (PORT) mode and Passive (PASV) mode?
Active (PORT) mode:
In active (port) mode the FTP client specifies
the data port that the FTP server is going to connect on and waits for
the FTP server to connect. The IP address and port number are sent to
the FTP server by the FTP client using the PORT command.
Passive (PASV) mode:
passive (PASV) mode the FTP server specifies the data port that the FTP
client will connect on and waits for the FTP client to connect. The FTP
client will ask the FTP server for the server's IP address and port
number by issuing the PASV command to the FTP server. This will usually
solve the problem of firewalls filtering the incoming data connection.
How can I enable PASV mode?
In the Administration console, under your server, go to the Connections category. On the Connections Advanced tab you will see a check box that reads "Allow PASV mode connections". Make sure this box is checked.
