Question

IP Spoofed packet successfully goes out from my PC, but not reaches to a target.

With wireshark, I monitored web traffic getting out from my pc and it is verified that ip spoofed packets are successfully submitted.
But in the target PC, no packet arrives.
Is this a routing problem?

Sure

Hmm are you running Wireshark on the target device? And is the target’s IP correct?

It works perfectly on the LAN, but not on Internet.

Ohhh I haven't tried against a public IP yet... only a private one. Do you have your own public webserver for testing?

Yes. if you want to test your project, just ping me up anytime.

One other thing is that this was more for demonstration purposes... most public webservers "should" have a way to block this sort of thing whether it be the tcpsyncookies flag or with IPtables or some other firefwall. You never know though :)

Thanks. I guess that is the answer for my problem.
