About Installing Cisco Unified MeetingPlace Web Conferencing Release 5.3 in a Load Balancing Configuration
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.
Figure 4-4 External Meeting Redirection from an Internal to External Web Server
1. First user attempts to join the web conference.
2. The Agent Service checks the web table to determine where the meeting should be held.
3. If the meeting is internal, the Agent Service finds the least busy internal web server and directs the
web-conferencing session to that server.
4. If the meeting is external (Internet-accessible), the Agent Service checks for an associated external
web server. If it finds one, the web-conferencing session is redirected to this server.

If Then
Allow Internet
Access is set to No This meeting is reserved for internal attendees only. When the first attendee launches the meeting
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.
Allow Internet
Access is set to Yes This meeting is accessible to external attendees, that is, participants attending from outside the
firewall.
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.
