Is this just not "allowed"? Are you trying to use 255.255.255.255 to reach something not on a local subnet? If you have multiple interfaces, a broadcast to 255.255.255.255 should go out on all of them. That being said, the all-ones broadcast address means "all local networks", and most routers will block such traffic from passing on in any event. -- -Chuck
