Thanks to everyone who responded. When you do an ls or dir on a remote host, it creates a "new" connection back to the server, so it is not persistent. It appears to be grabbing a random port in the 53*** area.
Is there syntax in iptables to allow all ports from a host over port 1024?
I also had to issue the *passive* command once connected before I could run an ls or dir.
If you want to have iptables firewalling between these two systems you could try the ftp_conntrack module. It is designed to handle this issue. It examines traffic on the standard FTP port which requests a DATA connection, and pokes dynamic holes in the iptables configuration to allow the data through.
