there is another way. you can make your proxie connect to another proxie
which
have the abililty to use the CONNECT mode.
get the program HTTPort ( http://www.technetva.com/httport/ )
It can tunnel connections through an proxy.

second way. if the ftp happens to be your own, change the port to 25 or 80.
