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 > > At 10:55 PM 1/21/98 -0500, Eric Osborne wrote: > > >How do you prevent packets from your network with a broadcast address, since > >what defines a "broadcast" address really depends on the subnet mask? > > > > "no ip directed-broadcast" > > - paul >
