5.2.6.4 IGMP Proxy
When IGMP Proxy (Internet Group Management Protocol Proxy) is enabled, the router can make intelligent multicast forwarding decisions by examining the contents of each frame’s IP header. Without the function, the router will broadcast the multicast packets to each port and may create excessive traffic on the network and degrade the performance of the network.
The IGMP Proxy screen allows you to enable multicast on WAN and LAN interfaces. The LAN interface always serves as a downstream IGMP proxy, and you can configure one of the available WAN interfaces as the upstream IGMP proxy. Upstream is the interface used when IGMP requests from hosts are sent to the multicast router. Downstream is the interface used when data from the multicast router are sent to hosts in the multicast group database.
