    I've set up my E4200 with toastmans build and i'm using it for IPTV but i encountered and issue when using multiple multicast sources and i dont seem to get over the problem.

    When i add the 4th muticast source simultaneously the router simply stops responding , everything on the LAN/WAN stops, devices on the lan cannot communicate with each other until i close one of the sources and then everything returns to normal , no reboot required , no message in the log , nothing.

    Each source has between 2.8 MB and 8 MB, and it doenst seem to be a resources issue because when im using 3 multicast sources the CPU Usage is 24.01% and the memory is 76% free..
    My ISP uses 2 vlan's and im actually running the IPTV in a separate VLAN with igmpproxy acting only on that vlan, internet traffic goes through a different vlan.
    Is there some limitation for the number of multicast sources? If 4 was the limit it would'nt be an issue because my ISP only grants 4 simultaneously!

    Note: i've tried with EMF enabled and disabled and it makes no difference.

    Best Regards.

    Well , i've tested the same implemetation on dd-wrt and it works fine so it must be a tomato issue.
    Anyone know the cause?

    Spoke too soon.
    I guess the router is being flooded with multicast traffic. Well i need the multicast to go just to one device and i cant segment the network because i access that device via LAN anyway .
    Can i configure dd-wrt in a way that alows only two devices to recieve packets from vlan12 and only one of them to recieve multicast without losing LAN connectivity on those devices ?
