To correct this problem, head over to the Ektron Web Server and give access to its external IP address.
Here are the steps to accomplish that:
1. On the Ektron Web Server, open IIS
2. Under "Connections" in the left panel, locate the Ektron Web Site
3. Click "IP Address and Domain Restrictions". The Add Allow Restriction Rule dialog should appear
4. Add the external IP address of the Ektron Web server.
