How to IP-Forwarding for Man In the Middle Attack

Question

I`m working on a project about Man In The Middle Attack by ARP poisoning method.

In this project I need to work like as a router. For example suppose In My Lan there is two other device (a modem & a laptop). I says to laptop that I`m the modem to fraud it. whenever the laptop wants to send a packet to outside of the LAN, sends the packet to me! All thing I need is I want to send the received packet to the modem & sends the response to victim laptop.

How can I do it programmatically?

Thanks a lot. Ya Ali.

Answer 1

Well the first thing you need to do is perform the ARP poisoning attack. You can review how to do this in detail here.

One thing of note is that your middle-man PC must how be able to perform like a switch and forward out packets it receives in - It will be passing packets between the modem and the laptop in both directions.
