service endpoints
By default your Windows Azure Web Host project is configured to accept traffic on ports 80 and 443. If you need to add additional ports or modify the defaults you will need to edit your Web Role endpoints and redeploy the cloud project.
To modify the endpoints double click your WebDeployHost.Web role.
Then click on the “Endpoints” tab. From here you can add, remove, or change the ports open to the web role.
Now just deploy your cloud project and your ports will be open for serving content.
