Thanks for answering my question. Shame that Fusion doesn't have that feature yet.
And yes it seems in Workstation for PC promiscuous mode is permanently switched on. And that there is no way to switch it off! I wonder how this effects security?
Surely both Fusion and Workstation should have a feature, like ESXi to enable or disable it.
Thanks again.
P.S. Thanks for the link about the “fix”. When I feel adventurous I will give it a shot!
