When you set up a network interface with PPPoE and want to use igmpproxy to redirect multicast traffic, the igmpproxy will not start up showing a message as if it did not recognize the interface. However, if an IPoE interface is used instead of a PPPoE interface, the program starts up correctly without any problems.

Here are the traces of running the igmpproxy program and I share screenshots of the configuration used:
