Hello,
Your server may be In Active mode, the FTP client chooses the port number that it will use to transfer data on and tells the server which client-side port to send the data to. It issues the PORT command to let the server know what IP address and Port number it will be listening on to receive the data from the server.
PORT 192,168,1,254,4,15
The server then initiates the data transfer to the client, sending the data to the port number that it was told to by the client. Since the Server has initiated the connection, a stateful firewall will not allow the data to be sent back though. (No client has created the connection and so no respective connection exists.)
Hope this helps.
Good Luck
