ftp routing / natting throu a RH7 firewall

Hi all,

I have setup iptables on RH7.
I now need to open a port for ftp access. I have chosen 40335 as the port as
apposed to 21.
From outside the firewall I can connect but cannot receive any folder or
file listings.
What am I doing wrong, and can anyone help with a script to get this working

Thanks
Robert

add to /etc/modules.conf

add above ip_conntrack ip_conntrack_ftp

and also add to /etc/sysconfig/iptables something like

-A INPUT -p tcp -m state --state RELATED -j ACCEPT
-A OUTPUT -p tcp -m state --state RELATED -j ACCEPT
