> 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?
> Thanks!
