DBG-2000 User Guide IGMP Proxy The Internet Group Management Protocol (IGMP) is used by hosts and routers on an IP network to create multicast group memberships. The IGMP can be used for web and support applications like the online streaming of videos and games. The IGMP proxy enables the gateway to issue IGMP messages on behalf of the clients behind it. If the IGMP proxy feature is enabled, select the WAN interface on which it is to be applied. IGMP Snooping IGMP snooping allows the gateway to 'listen' in on IGMP network traffic through the gateway. This allows the gateway to filter multicast traffic and direct it only to hosts that need this stream. This is helpful when there is a lot of multicast traffic on the network where all LAN hosts do not need to receive this multicast traffic. The fields available in the Configuration table are as follows: Field Interface IGMP snooping Actions Description It displays the interface on which the IGMP snooping is configured. It displays if the IGMP snooping is enabled or disabled. It allows you to delete the configured IGMP snooping one at a time. Click Add to add a new interface. This opens the Add interface configuration page. To delete more than one configured IGMP snooping, select the checkbox of the corresponding configured interface, and click Delete. 70
