IGMP Proxy
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:
1. Enabling IGMP proxy on a WAN interface (upstream), which connects to a router running IGMP.
2. Enabling IGMP on a LAN interface (downstream), which connects to its hosts.
