Re: IGMP timeout bug - UDP multicast messages being blocked?

I forget the details but I think this might be worth a try anyway. Send out a multicast message every minute. Nothing specific, just on that port.
I wonder if your router isn't passing through the messages after a time out. (again, I forget the specifics) for the problem (maybe not this one) the workaround was sending a packet periodically to indicate to the router that you still want the communications to continue on that port.
