Connection Errors Due to Firewall Restrictions

If you receive an error message indicating that your Distance Learning client software cannot connect to a Distance Learning session, your network may be using a firewall that blocks normal Siebel Distance Learning transmissions. If so, you may be able to use either an HTTP Gateway connection or an HTML Viewer connection to participate in the session.

An HTTP Gateway connection is available if the organization that is presenting the Distance Learning session is running an HTTP Gateway server. Such a connection provides full functionality during the Distance Learning session, but performance may be slower than a regular Distance Learning TCP/IP socket connection would provide. For information about using an HTTP Gateway, see To configure an HTTP Gateway.

NOTE:  If you plan to have attendees use the HTML Viewer, you should install the HTTP Gateway on the Siebel Distance Learning server.

If the Distance Learning server is configured to provide HTTP functionality, and if it is not possible to access the session using Distance Learning client software, a prospective session attendee who is located behind a firewall can click the HTML Viewer icon on the Conference Center screen to use an HTML Viewer connection. Attendees who use an HTML Viewer connection can hear the audio portion of the session through a standard telephone conference call, but they can not use the following capabilities of Siebel Distance Learning:

For information about using an HTML Viewer, see To use the HTML Viewer.
