Subject: Security Groups and IGMP

Good Afternoon!

We are working with multicast and IGMP groups on our CloudStack infrastructure, and I have
a question regarding security groups.

To create an ingress rule, one must navigate to the security groups panel then add a new rule
based on protocol. The values allowed are ICMP, TCP, and UDP. I am concerned that the IGMP
member query messages on the network are being
+blocked by the security group settings, as our VMs continually act as if they have been kicked
out of the membership group.

Are IGMP packets blocked by security groups by default? If so, how do we enable them?
