Change supply and vacation spot adresses from a legitimate captured ping to create a legitimate ping with totally different supply and vacation spot

I wish to create site visitors in my community, particularly
I wish to ship a repetitive ping to the system with the IP 192.168.3.146 from my site visitors generator (IP 192.168.3.100) (see scematic)

For the creation of the ping I captured a ping from PC to system with the IP 192.168.3.145 and modified this, that means I modified

• the supply IP
• the vacation spot IP
• the supply MAC
• and the vacation spot MAC

I now additionally calclulate a brand new IP header checksum.

If every little thing is finished accurately the despatched ping from 192.168.100 to 192.168.3.146 ought to be answered I assume. Nonetheless it doesn’t occur.

For troubleshooting I solely modified the vacation spot IP and vacation spot MAC of the captured ping and despatched it with my site visitors generator. Which means from my site visitors generator I despatched pings from with supply IP 192.168.3.1 and vacation spot IP 192.168.3.146 (+calculation the brand new IP header checksum). Nevertheless, this pings are answered by the system.

I take advantage of TAP in an effort to seize the site visitors.
I hope that is clearly described.

Thanks for answering.
