Many thx for pointing out this very important point. I thought that there was only one traffic stream (i.e. the normal flow) But if I want to modify the packets in the normal flow, let's say manipulate their mac address, how do I go abt it. Do you have any clue how I can interact directly with normal flow. I've heard abt the Libnet library. Can they do it?
