Depends on the implementation - you set an IP -> if you choose the SAME ip, this will cause problems -> if you choose another ip, you won't see any problems. All packets for the authorized client, are going to be discarded by your IP stack, and all your packets, by his IP stack.Right. So it depends on whether a DHCP server is in place, and, if it is, how it is configured? And if you choose another IP address (manually), it doesn't matter if you have the same MAC as the other client or not... Doesn't this depend on what type of hardware it is? I suppose it depends on what is being used to route the packets, as (if I'm not mistaken) some do this by MAC and others by internal (NATed) IP?
I think it does matter. Because there will be more than host replying to ARP broadcasts and the question is what will happen.
