True. FTP negociates the data channel in the data stream (in both active and passive modes).
There is no way for NAT to accomodate this without inspection of the FTP data stream. This means
that a proxy is required to perform NAT and FTP through a firewall (or some very lax firewall rules).

IPFilter has an in-kernel proxy. You can use that (though it's not 100% reliable).
Using a proxy outside the NAT box will also work...
