Please forgive the obvious, but do you also have
natd_enable="YES"
to make the NAT daemon start?

That will not work. From the internal net, you will need to ftp to : directly. NAT processes only those packets which travel via the
external interface of your NAT/firewall box. To test the NAT and firewall
rules, you will have to test from a machine outside your firewall. If you
have access to a dial-up account, that will suffice, or perhaps you can ssh
to a shell account on another machine, and then try to ftp back to your
public IP.
I would suggest you test first from the internal LAN to ensure that you can
ftp on port to the internal IP of your ftp server. This will show
you whether the ftp server itself is working as you think it should. Once
you know the ftp works on the internal LAN, then you can test from a machine
_outside the firewall_ to get the natd redirection happening.
