OK, so here is the scenario:

I have three computers, each computer has 6 physical network cards. And a powerful computer with one network card. All four computers are linked through a switch, so the three computers end up with 5 available network cards for a total of 15 NICs. Is there a way/software to virtualize all 15 NICs on the powerful computer, by creating a link from the virtual NIC on PC "A" (the powerful one) to physical NIC on PC "B"???

I study for my Cisco Cert. and instead of dropping $600 on quad-NIC PCI cards, I rather do it this way, because I already got this hardware for free.

Any input would be great, I did some research, but I couldn't anything.
