What you're trying to do could be an extremely tricky proposition, because
of the multiple ports involved in an FTP connection. SCP and FTP are also
two completely different protocols, and I'm guessing it's highly unlikely
it'll be an easy matter to make an FTP proxy support it.
You may have more luck with SFTP or FTP over SSL.
