I would like to bridge some network cards so that my virtual machines, running in VMware workstation 9, can connect through them, but not the physical windows computer on which the VM's are running. How do I do that?

I want one NIC to connect the host machine to the internet, and the rest of the NIC's to connect the VM's to the lab network.

Right now my host machine loses internet connection the second I connect any of the bridged NIC's to the lab network. Also, port security keeps seeing two MAC-addresses on each bridged NIC - one from the VM and one from the host - shutting the port down all the time.

You will see two MAC addresses on a bridge, because a bridge is just like a switch. You need a router which can perform forwarding to have all of the MAC addresses rewritten to a single MAC address. – Darth Android Jun 19 '13 at 22:10
    
i know why it's happening. I'd like to remove access from the host machine, and only let the VM access the interface. – Filip Haglund Jun 19 '13 at 22:14
