When you do FTP its actually two TCP connections, a outgoing to port 21, and
then a incoming. The most common problem with FTP is that the incoming
connection gets blocked by a firewall or NAT. So most people use passive FTP
where instead it makes two outgoing TCP connections.

I think the directory listings are sent over this 2nd connection, so I would
suggest your problem is that the incoming data connection is being blocked
by a firewall on your server. Try to either use passive FTP or to change
your firewall rules.
