Firewall Rule to drop IGMP

The utm wan interface is connected to a switch which also receives IGMP multicast packets. (They are for IPTV which is on a separate network from utm.) I would like to configure the firewall to ignore these packets instead of log them. I created a rule to drop all packets from the particular source that are being sent to the all hosts multicast address (224.0.01). I wasn't sure how to do this, since IGMP cannot be selected as a service or protocol. Is there a more correct way to do this aside from selecting ANY?

Note, I realize the packets are already getting dropped by the firewall. I just don't want them to be logged.
