Step 1. Log in to the web configuration utility and choose Advanced > Network > Application. The Application page opens:
Step 2. Choose an option from the Multicast Passthru drop-down list under the Miscellaneous Settings area:

Outbound Only — Only outgoing multicast traffic from the device to the Internet is allowed.
Inbound and Outbound — Both incoming and outgoing multicast traffic is allowed.
