This section provides configuration tasks for Multicast Snooping. The Firewall Settings > Multicast page allows you to manage multicast traffic on the SonicWALL security appliance. Multicasting is a point-to-multipoint IP communication mechanism that operates in a connectionless mode - hosts receive multicast transmissions by “tuning in” to them, a process similar to tuning in to a radio. In mutlicasting, the sending host transmits a single IP packet with a specific multicast address, and the 10 hosts simply need to be configured to listen for packets targeted to that address to receive the transmission. For example, a single host transmitting an audio or video stream and ten hosts that want to receive this stream. Multicast is suited to the rapidly growing segment of Internet traffic - multimedia presentations and video conferencing.

Multicasting, also called IP multicasting, is a method for sending one Internet Protocol (IP) packet simultaneously to multiple hosts.
