If using a “passive” FTP connection setting, the client computer also connects to the server on FTP port 21. However, the server responds with a random port number, in a free range of ports, to use for the data port for file transfers. For example, your FTP client will open a contr...
By default, FTP uses a dynamic port allocation process to negotiate the data port number that will be used for the file transfer. The client and server send messages back and forth over the control connection to determine an available port number that they can both use. Once the data port ...
4. The client sends an FTP PORT command that talks about using the active FTP mode, its IP address, and also the port number for establishing a data connection to which the server will connect. 5. The command is confirmed by the server. ...

Yet, FTP servers may be set up to use an alternative port number for the control connection. Data Port: File transfers between the client and server take place across the data port. Both the active mode and the passive mode of data transfer are used by FTP. Use distinct methods for ...
This property specifies the range of data ports to be used by the FTP service in response to PASV commands.PASV FTP requires the server to open a data port for the client to make a second connection. This is a seperate connection than the typical port 21 that is used for the control ch...
IP headers only indicate the destination IP address, not the port number at that IP address. Usually, the inability to indicate the port at the network layer has no impact on networking processes, since network layer protocols are almost always used in conjunction with a transport layer protocol...
