The NBG420N supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). 
At start up, the NBG420N queries all directly connected networks to gather group 
membership. After that, the NBG420N periodically updates this information. IP multicasting 
can be enabled/disabled on the NBG420N LAN and/or WAN interfaces in the web 
configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.
