Spoofed Packets Send From Container

Hi everyone,

I have a cluster for DDoS testing. But in container, I can’t send spoofed packets to target.
Because, Actually when I spoof source ip with random ip, packet forwarding to host machine.
And host machine override source ip with own IP address and send the target.

How can I send packet directly from container ? Without host machine interaction ?
Or any ideas ?

Thanks…
