We have a setup that may require having a multicast router in a network that contains other multicast activity. This extra router would only want to route multicast traffic (control and data) for a specific multicast group (our test group), ignoring all other multicast traffic not part of that group. I know that the matching code is able to match on a multicast packet type, but I need to match on a specific group. I looked around the docs, but have been unable to find any kind of --match type support for multicast group ID's or some sort of IGMP connection tracking/handling. Is there something I missed? Can this be done with existing tools? Or else, could this be easily constructed?
