I have two intel pro 1000 pt nics. One quad and one dual port. I want to assign all nic ports to a VM. I enabled PCI passthrough on all devices but ESXi will only allow me to add two nic ports until it tells me the maximum number of pci devices have been added.

I have also tried setting up a virtual switch but it didn't seem like this would give full access to the nics.

What is the best way to setup the nics to the VM has direct access to them? This is for a firewall VM.
