I have set up the My Cloud EX2 Ultra to be accessible via FTP as per the documentation, and have ‘Report external IP in PASV mode’ enabled, and have confirmed the IP address entered. In Passive Mode, it is configured to use the default port range of 55536 - 55663.
Port Forwarding on the EX2 is configured:

The Share on the EX2 has been configured so that all authenticated users have read/write access, and Anonymous Read / Write has also been enabled for testing purposes.
Log file when attempting to connect from FileZilla (note that this tries to list the root directory before giving the option to change directory):
