Advanced Setup Method
Description: detail description of the VLAN
IP Address: IP address of the VLAN virtual interface on the gateway
Subnet Mask: subnet mask of the VLAN virtual interface
NAT Domain: NAT addressing domain to define the NAPT operation
of the VLAN virtual interface. Public means that this VLAN will be
visible to the Internet. Private means NAT is enabled to protect the
subnet from visibility to the Internet
IGMP Snooping: enable/disable the feature to block unnecessary
IP multicast traffic flooding among VLAN ports without the specific
multicast membership. This feature is working based on snooping
IGMP Join/Leave messages among the VLAN ports to update the
bridging forwarding database. IGMP Snooping is extremely useful in
saving bandwidth of low-speed interfaces (ex. WLAN) to improve the
network utilization
IGMP Querier: enable/disable IGMP querying to the VLAN virtual
interface. The option is to control whether to behave as an IGMP
querier on the VLAN bridging network. If IGMP Querier option is
disabled, the router will act as an IP multicast compliant host and
send IGMP reports for its own joined IP multicast groups. No IGMP
query messages will be sent to the specific VLAN
