      The IGMP Proxy page allows you to enable multicast on WAN and LAN interfaces. The LAN   

        interface is always served as downstream IGMP proxy, and you can configure one of the available   

        WAN interfaces as the upstream IGMP proxy. 

 

Upstream: The interfaces that IGMP requests from hosts are sent to the multicast router. 

Downstream: The interface data from the multicast router are sent to hosts in the multicast group 

database.

The upstream WAN interface is selected here. 

 

 

 

 

 

 

 

 

   The   device supports a control point for Universal Plug and Play (UPnP) version 1.0, and 

supports two key features: NAT Traversal and Device Identification. This feature requires one 

active WAN interface. In addition, the host should support this feature. In the presence of multiple 

WAN interfaces, select an interface on which the incoming traffic is present. 

 

With NAT Traversal, when an UPnP command is received to open ports in NAT, the application 

translates the request into system commands to open the ports in NAT and the firewall. The 

interface to open the ports is given to UPnP when it starts up and is part of the configuration of the 

application.
