You do not need any redirection rules nor transparent proxying
if you have only one ftp-server - simply set DestinationAddess
to the IP of the ftp-server and say to the internet, the proxy
machine is your ftp-server.

start a second ftp-proxy with transparent proxying in the
internal interface of the proxy machine.
