[CentOS] ftp firewall/iptables

I just installed CentOS4 on my main server. It runs proftpd and is not NATted..

When I did the install I said to allow FTP and HTTP. I can ftp from
windows dos ftp client.

In IE I get "Unable to build data connection: No route to host"  

ncftp I get.. 
Data connection timed out.
Falling back to PORT instead of PASV mode.
List failed.

Wget and FireFox just time out.

 Anything I need to add to the firewall rules? This is all it has
related to FTP.
-A RH-Firewall-1-INPUT -p tcp -m state -m tcp --dport 21 --state NEW -j ACCEPT
