Network

Hi everyone,
I am searching for a way to do a MITM attack on my Windows 10 machine.
I have root access to this machine.

I want to intercept packets between my machine ethernet network interface and a device.
When I say intercept packets, I want to not only capture packets, I want to tamper packets. The protocol will be ### because for the moment I only want to modify some hexadecimal value, I will be really happy to succeed this step even if I break packets checksum or the entire protocol.

Thank you for any kind of help!
