Yeah, but the original post said something along the lines of "any packets to or from my network to a broadcast address". It's not the "to" part of that which is a problem, but the "from" - as you know, x.y.z.3 can be a host or a broadcast address (if it's a /30 mask). In other words, I can't prevent my customers from sending packets to a broadcast address, esp. on a subnet smaller than /24. You might be able to block outgoing packets for destination x.y.z.255, but if you've got a mask >/24 (/23, etc..), couldn't .255 be a valid host address? Just being picky, I suppose.... eric
