Ok, I dont get it. Can someone tell me why you need ip directed broadcast on
both ends, when using the ip multicast-helper map? Some examples of using
directed broadcast with ip helper would be nice as well. Are there any
situations where you would need to put it on both source and dest with ip
helper?
Thanks,
DR
