If host "x" is on the same IP Network, I don't think the router would be a concern as there would likely not be the same ip network on more then one of the routers interfaces. Some switches have options to block stuff tho, but it's not too common to find that feature used on a small LAN. -John --- Doru Petrescu <pdoru () KAPPA RO> wrote:
There is another problem with your scenario. A well configured router will not accept to forward a packet to a brodcast address. Why ? Imagine someone sending a fake echo request from a brodcast address to your brodcast address.

Lets say i work in a subnet with IP pool from(just for example)195.195.120.10 - 195.195.120.25, so it have 15IP's and its broadcast would be195.195.120.25. Now i want to hide my real IP fromX host and send packetswith source address of broadcast (195.195.120.25).If im not missed anythingthe X host will send replies to that broadcast andi will recieve them.Correct me if im wrong and this wont realy work. Thanx, Max.P --
