Me, I have to stay using the ISP provided router, I can not insert another one because then the TV would stop working.
Can you not put the router portion in bridge mode?
I would have to replicate its functionality on the inner router, and that functionality is not documented.
Question: does IGMP snooping traverse routers? The TV uses that.
No. IGMP traffic is not routed beyond the local subnet. Other protocols (PIM - Protocol-Independent Multicast - in Sparse Mode, Dense Mode or Sparse/Dense Mode, or SSM - Source Specific Multicast) are used for that. Multicast sources or receivers talk to the local router using IGMP - routers manage propagation and routing of multicast group traffic between networks or subnetworks using PIM. IGMP Snooping is a method for switches (L2 devices) to learn what ports have devices registered for multicast traffic on specific groups and limit the multicast traffic to those ports. Without IGMP snooping, multicast and broadcast traffic are treated the same way (flooded out all ports except the ingress port). (This will get way off-topic for the OP really quickly). -- ============================================================== Rodney Baker VK5ZTV rodney.baker@iinet.net.au CCNA #CSCO12880208 ==============================================================
