Acces Problem in Amazon EC2

Hello,
I've installed CWP on my Amazon EC2 tier1 server. I get the HTTP Test Page but I can't access to admin panel. I did some research and saw that it's related to 2030 port. I've opened 2030 port via putty (I checked, it's listening) and also gave permission via ec2 control panel security settings but still I can't access to admin panel. What might be the reason?

Try this commands:

service iptables stop
service httpd restart
service named restart
service cwpsrv restart

Check in your security group that you allow access to the port you want to use in Amazon web panel
