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?

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

[tigersoft18]

Sure

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?

[tigersoft18]

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.
