IGMP
This category includes the IGMP protocol.
IGMP is used by hosts and routers to dynamically register and discover multicast group membership.
Attacks on the IGMP protocol usually target a vulnerability in the multicast routing software/hardware
used, by sending specially crafted IGMP packets.
You can configure how IGMP attacks should be handled.

address might constitute and attack; therefore the IP60 appliance blocks
such packets.
