I want to do a stress test using iperf in Lubuntu using a single machine. I've tried doing the dummy IP route, I've tried changing the ip route table, yet still it goes through the local host and doesn't stress the switch.

Any suggestions? The first thing I tried was a virtual machine, but as one might have guessed it still goes through the local host.

Is there any where I can modify the ARP settings so that the local host doesn't see a NIC as local? I'm using a wifi and ethernet, but I can do another ethernet port with a usb adapter.

My final idea was maybe find a way for the virtual machine to use a wifi card that the physical machine doesn't recognize but I don't have any wifi cards that require fancy drivers, and I'm not even sure if that would work.
