A very strange question. When the client sends you a echo-request, it expects to receive echo-reply from the same IP address. If some other IP address sends the echo-reply, it will simply get dropped by the OS on the client, as there is no match for this bogus packet... Now, what do you want to achieve with this? Fool the client that his ping, pinged someone else?? If you feel unconfortable with someone pinging you, just drop them...
