The ls command is usually the data portion of the FTP connection.
Have you tried changing the mode to passive (or to active if you are already
using passive)?

Subject: Broken ftp through iptables
Hello,
I've ran into a recent problem both on rh8 and
rh9 using iptables. I've
setup my firewall to drop everything
incomming and forward and am only
allowing certain ports to be open.
I've opened ftp (port 21 tcp) and I
can connect via FTP from one machine
and authenticate, but when I issue
my first command like "ls" for instance
the connection locks up and
won't do anything. Is there a way to fix
this?
Landon
