How to Configure Windows Firewall for a Passive Mode FTP Server. Using the File Transfer Protocol FTP service on a server behind a firewall creates a set of challenges because of the way FTP works. A standard mode FTP client initiates a session to a server by opening a command channel connection to TCP port number 2. A file transfer is requested by the client by sending a PORT command to the server. The server then attempts to initiate a data channel connection back to the client on TCP port number 2.

Instead of using the PORT command, the client sends a PASV command on the command channel. The server responds with the TCP port number to which the client should connect to establish the data channel. By default, the server uses an available port in the ephemeral range 1. To better secure the server, you can restrict the port range used by the FTP service, and then create a firewall rule that allows FTP traffic on only those allowed port numbers.
