4.5.5 IGMP
Proxy
The page allows you to enable or disable the IGMP (Internet Group Management Protocol)
proxy. IGMP is used to establish the multicast groups to forward the multicast packet to the
member ports. It can very effectively reduce multicast traffic from streaming and other
bandwidth intensive IP applications.
IGMP proxy enables the system to issue IGMP host messages on behalf of hosts that the
system discovered through standard IGMP interfaces. The system acts as a proxy for its
hosts when you enable it by doing the follows:
Enable IGMP proxy on WAN interface (upstream), which connects to a router running
IGMP.
Enable IGMP on LAN interface (downstream), which connects to its hosts.
