Hi all. If you have two sources from two different inside interfaces sending multicast data to the outside interface and both sources use the same multicast address (G1) then outside routers, using for example PIM-SM, will consider that there is only one multicast channel and will send all the traffic. Also hosts receiving all the traffic need to separate it. One solution is to reserve an IP address range inside SSM range ( for example 232.0.0.0 to 232.0.255.255) and let the NAPT change, not only the source address of the sender, but also the multicast address of the sender to be unique in this range. In this way outside routers ( and receivers ) will consider traffic as coming from different channels (IP public ,G2) and ( IP public, G3) with G2 and G3 inside the said range.

Thanks! http://www.ietf.org/internet-drafts/draft-ietf-behave-multicast-06.txt: What if the NAPT or NAT device just passed IGMP queries and reports through, changing only the source address of the reports, and let the multicast router outside do all the hard work? I'm wondering whether the IGMP aggregation function is mandatory in NAT/NATP.
