User Manual
Multicasting is useful when the same data needs to be sent to more than one device. For
instance, if one device is responsible for acquiring data that many other devices need,
then multicasting is a natural fit. Note that using multicasting as opposed to sending the
same data to individual devices uses less network bandwidth. The multicast feature also
enables you to receive multicast video streams from multicast servers.
The IGMP Proxy page allows you to enable multicast on available WAN and LAN
connections. You can configure the WAN or LAN interface as one of the following:
Upstream The interface 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.
Ignore No IGMP request nor data multicast are forwarded.
You can perform one of the two options:
1. Configure one or more WAN interface as the upstream interface.
2. Configure one or more LAN interface as the upstream interface.
To configure the IGMP Proxy:
1. From the Advanced Menu, select Application > IGMP Proxy.
2. Check Enable IGMP Proxy.
3. Configure the listed interfaces.
4. Click Submit to temporarily apply the settings.
5. To make changes permanent, click Save Settings.
