Oh.... re-read OP
Its not ESXI.. There is a setting in VMWARE workstation somewhere that "shares" host ip or assigns a new one. Have a dig around. Think its when you create the VM but might be when you edit it as well.
This is where you have to select the Bridge network in order for it to read the VM as a separate machine. However, even if I select VM0 it does not translate into the system recognizing it as such.
You can also change it here, but no dice. It doesn't work.
