Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data.
Select this option to have the Device act as an IGMP proxy on this connection. This allows
the Device to get subscribing information and maintain a joined member list for each
multicast group. It can reduce multicast traffic significantly.
Select this option to have the Device use the WAN interface of this connection as the system
default gateway.
This is available only when you select IPv4 Only or IPv6/IPv4 DualStack in the IPv6/
IPv4 Mode field.
Select Dynamic if you want the Device use the DNS server addresses assigned by your ISP.

IPv6 address from a DHCPv6 server. The IP address assigned by a DHCPv6 server has
priority over the IP address automatically generated by the Device using the IPv6 prefix
from an RA. This option is available only when you choose to get your IPv6 address
automatically.
Select Static if you have a fixed IPv6 address assigned by your ISP.
Enter the IPv6 address assigned by your ISP.
Enter the address prefix length to specify how many most significant bits in an IPv6 address

same segment as your Device's interface(s). The gateway helps forward packets to their
destinations.
