Multicast Address
The company has a large high tech campus that has monitors in many of its meeting rooms. It is common practice for company wide notifications of importance to be done in a streaming video format with the CEO of the company addressing everyone at once. The video is High Definition quality so takes up a lot of bandwidth. To minimize the impact on the network the network administrators have set things up to allow the use of multicasting to the monitors for these notifications. Now it has to be set up on the FortiGate firewall to allow the traffic.
• The range being used for the multicast is 239.5.0.0 to 239.5.255.255
• The interface on this FortiGate firewall will be on port 4
