Is it possible to configure router to reply to ALL ICMP Requests?

By jerrydurden ·
I am trying to configure a Cisco 2600 series router with the ability to respond to ping requests no matter if the devices are online or not. I would like the person performing the ping request to believe that the device is alive on our end. Is this possible?

if I understand correctly, you want something to respond when nothing is there?

This is exactly what I want to occur. In theory, I may not have any devices behind the router, but I want the router to reply back as though there are devices online for each IP within the entire range. I know its a wierd request, but I am simply trying to find an answer. Thanks for all the help.

Not to be redundant but, the best device to respond to a ping when your Cisco 2600 is offline would be a secondary online Cisco 2600.

This is a great way to create a honeypot. It is possible just create a loopback address on the router for the range of ip's that you want a return, of course it will give a host not reachable return but the network will respond to the ping. Then you can log the attempt to record repeat hacking attempts. Of course anything beyond the loopback is essentially a black hole and will drop any attempts to go deeper into the loopback network.
