SYMPTOMS

RFC 959 allows for the use of the PORT command, a remote connection to another TCP\IP over a passive connections, to be established based on the port address given by client. This is commonly done with FTP server-to-server transfers. This behavior was made optional to provide added security to the FTP service.

The FTP service compares the IP address that makes the connection and the address issuing the PASV command. If they are different, the FTP service does not allow the connection. When you attempt to do this on the Microsoft FTP Server, this operation fails, regardless of the settings.
