ajax請求在調用wcf服務時拒絕訪問

我創建了一個amazon EC2實例，並在端口80上託管了我的.net Web應用程序，並在端口1212端口上託管了WCF服務。ajax請求在調用wcf服務時拒絕訪問

本地在遠程會話中，我能夠瀏覽應用程序和服務，並能夠進行ajax請求調用。

只有當我嘗試通過互聯網（不在相同的遠程會話）上做相同的功能，這使得在端口1212上的ajax調用wcf服務時``會導致拒絕訪問錯誤。我添加了$ .support.cors = true;同時提出要求。

Web應用程序web.config：

    <system.web> 
     <connectionStrings> 
      <add name="ApplicationServices" 
       connectionString="Server=somedbinstance.asdkfjlksd.us-west-2.rds.amazonaws.com;Initial Catalog=xed; user id=user ;password=pwd"
