Directed Broadcast is generally discouraged, and a BCP was published not too long ago officially deprecating it (updating the router requirements to require such a function to default to `off'). More general forwarding of broadcasts is impossible without an appropriate routing protocol; all such protocols currently in existence are targeted at multicast, and not broadcast, since multicast is the correct, officially-sanctioned way to make such transmissions. (You'll note that multicast is a mandatory element of IPv6; IPv6's analogue to ARP uses it instead of interrupting every machine on the network.) -GAWollman To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
