Good luck. I wasn't able to get this going with NAT.

ip_masq_ftp is not designed to do this. It just works with clients inside
and servers outside. I used to use redir for this kind of setup, but with
the latest FTP exploits decided to go full proxy. This is the only secure
way to set this up. Unfortunately there does not seem to be a fully
transparent ftp gateway except ftp-gw from fwtk combined with some patches
from the wild.
