Idea on spoofed packets?
I was just wonder about this and couldnt find any perfect answer in google too. I just wanted to know, if i send a spoofed packet to someones computer, how do i get it back (or is it atall possbile?) . What i mean is that, suppose a network only allows a particular IP through their router (or firewall, whatever). Lets say the IP is 220.127.116.11 (for example). Now, if i manage to spoof a packet claiming its Ip to be 18.104.22.168, it gets inside the network well and fine, but how do i get the reply back to my computer (which ofcourse has an IP other than 22.214.171.124), eg: in case of icmp reply. No i m not trying to run any DoS attack or trying to hack anyones network, i just want to know it for the sake of knowledge.
Thanks in advance,
