    Just curious that the log message will display on USG when your local PC which behind USG try to access FTP?
    The FTP bounce attack is an exploit of the FTP protocol. Here is more detail.

    Yes, the error display, when local user try to connect remote ftp. And the connection does not occur.
    I did this rule for all lan ip, and part of PC connect, other part falls with subject error.
