ajax request giving access denied while calling wcf service

Question

I have created an amazon EC2 instance and hosted my .net web application on port 80 and WCF service on port 1212 port.

Locally on the remote session I am able to browse both application and service and able to make ajax request calls.

Only when I try doing same functionality over the internet(not on same remote session) which makes ajax call to wcf service on port 1212 ``gives access denied error. I have added $.support.cors = true; while making request.

Web application web.config:

<configuration>
    <system.web>
        <connectionStrings>
            <add name="ApplicationServices"   
                 connectionString="Server=somedbinstance.asdkfjlksd.us-west-2.rds.amazonaws.com;Initial Catalog=xed; user id=user ;password=pwd" 
                 providerName="System.Data.SqlClient" />
        </connectionStrings>
    </system.web>
    <system.serviceModel>
        <behaviors>
            <endpointBehaviors>
                <behavior name="webEndpoint">

                </behavior>
            </endpointBehaviors>
        </behaviors>
        <bindings>
            <webHttpBinding>

        </bindings>

            <endpoint name="BasicHttpBinding_ICustomerRequestService" 
                address="http://10.90.12.121:1212/myservice.svc" 
                binding="webHttpBinding" bindingConfiguration="webHttpBinding" 
                behaviorConfiguration="webEndpoint"

WCF Service web.config:

You need to add this port to AWS console->EC2-->Security group-->Inbound rules-->Port. This link will be helpful. You need to select security group corresponding to your instance, and this is also visible in instances link.

LINK1 , LINK2

Also make sure, you have added this port to windows firewall inbound rule. - http://technet.microsoft.com/en-us/library/cc947789(v=ws.10).aspx

Note: You might need to configure WCF service to be CORS ready, follow this link - WCF REST Service Template 40(CS) Cross domain error, i have answered there how to make it CORS enabled.
