TRB245 IGMP Proxy

The information in this page is updated in accordance with firmware version TRB2_R_00.07.10.2.

Summary

IGMPproxy is a simple dynamic Multicast Routing Daemon using only IGMP signalling (Internet Group Management Protocol). IGMP proxy enables the device to issue IGMP host messages on behalf of hosts that the device discovered through standard IGMP interfaces. The device acts as a proxy for its hosts.

Routing is done by defining an "upstream" interface on which the daemon act as a normal Multicast client, and one or more "downstream" interfaces that serves clients on the destination networks.

This chapter of the user manual provides an overview of the IGMP Proxy page in TRB245 devices.

Note: IGMP Proxy is additional software that can be installed from the System → Package Manager page.
