Forwarding Multicast Packets

Hello, I am having an issue with one of our NS5GTs that is installed on a LAN behind a clients firewall.  The untrusted port is on a 172.16.0.0/16 network with a VOIP phone system that is sending multicast packets to 224.0.1.59.  Our Netscreen is routing those packets back to the gateway and causing unnecessary and increase traffic on the network.  I have tried to create a policy to deny this traffic, but it does not work.

If someone has solution that will prevent the Netscreen from routing these packets that I can try it would be appreciated.

Thanks,

Joe Michl
