public ip of the ec2 instances redirecting to private ip

public ip of the ec2 instances redirecting to private ip

I am setting up chef-server on ec2 ubuntu instance. After installing the
chef on the ec2 13.04 instance, and I have attached the elastic Ip address
to it and mapped a domain to the ip in the godaddy. Whenever I hit
chef.myserver.com it redirects me to the private ip of the aws ec2
instance. Also I am whenever I try to hit chef.myserver.com:4040 to access
the web_ui it redirects me to the same private ip of the instances. A
quick googling showed some thing about FQDN, but I am not to figure out
how do I set it up in the ec2 instance. Kindly help me out.
