You need some kind of cooperation from the other server.
It sounds like you're trying to get around security precautions of the
other server, but if that's not the case, you ought to work this out
with the administrator of the other server.
You can't create an IP tunnel over an FTP server; at least, not using
any FTP server software I know well...
