Thanks in advance,

Try opening port 20 as well. Also please tell us what error you get when trying to connect via FTP

RMI

I think you should add a rule like

-A RH-Firewall-1-INPUT -m conntrack -ctstate RELATED,ESTABLISHED -j ACCEPT

When i try through logging ftp in command promt i was able to login but through GUI like filezilla and internet explorer i was not able to login,can any one help me on this.The below error iam getting while connecting the server through ftp

Did you open port 20? You need to configure your FTP server to use a certain port range for passive connections and then open that port range in the firewall as well.

Since you are using vsftpd you need to add this to vsftpd.conf:
and for the firewall:
RMI
