After configuring the FTP portfilter, you can open an ftp session from Remote to Local, however you can issue
ftp commands (e.g., login, cd, etc.) but transfer data (e.g., ls, dir, get, put commands). The portfilter allows an
ftp control channel but does not allow the use of a secondary data channel for passing data by ftp.
To enable the ftp data channel, add a trigger which will open a secondary channel only when data is being
passed. This prevents the need to open too many ports which offer a security risk.
