If	Then
Allow Internet	This meeting is reserved for internal attendees only. When the first attendee launches the meeting
Access is set to No	console, the Agent Service directs the web-conferencing session to the least busy web server in the
	internal cluster. This web server now owns the meeting. All subsequent attendees are directed to this
	server for their web conference.

	If the first attendee attempts to join the web conference from an external web server, the Agent Service
	finds the least busy web server in the external cluster. The web-conferencing session is directed to that
	server, which now owns the meeting.
	If the first attendee attempts to join the web conference from an internal web server, the Agent Service
	determines if it has an associated external web server. Such information is found on the Web Server
	Properties administrative page in the DMZ Web Server field.

•If there is an entry in the DMZ Web Server field, the Agent Service performs a redirection to that external server.

•If the Agent Service does not find an entry in the DMZ Web Server field, the web-conferencing session is directed to the least busy internal server as described for internal meetings. All subsequent attendees are directed to the same web server for their web conference.

Internal users can join both internal meetings and external meetings. If a meeting is designated as external, internal users who log in to an internal web server are redirected to an external web server.

External users can only join external meetings on external web servers.
