example, 192.168.1.1 (factory default).
Subnet Mask
Type the subnet mask of your network in dotted decimal notation, for example 255.255.255.0

you enter, so do not change this field unless you are instructed to do so.

IGMP Mode
Select Standard Mode to have the VMG forward multicast packets to a port that joins the
multicast group and broadcast unknown multicast packets from the WAN to all LAN ports.
