I have two machines A and C mutually connected to NICs on a third machine, B, as follows: A-B-C

B is a Windows 7 machine configured with a bridge containing the A-B and B-C NICs, so that A and C can communicate. So far, so good.

I need frames from A destined for B to also arrive at C. Essentially, I would like Windows to behave like a hub rather than a switch. Is there any way to do this?

If you have any ideas at all, no matter how hacky or roundabout, I would love to hear from you! I have been tearing my hair out over this and by now I am willing to try anything. My only limitations are that I can't touch A or change to a different operating system on B.

Why don't you just buy a HUB....they are extremely cheap? –  Cheekaleak Jun 9 '12 at 15:29
    
Machine C is a VM on B. –  dromedary Jun 9 '12 at 15:34

@dromedary What virtualization software? –  Shane Madden Jun 9 '12 at 20:02

Have you tried configuring the VM to share the physical adapter with the host rather than using a virtual adapter and bridging? –  Harry Johnston Jun 11 '12 at 21:20
    
HyperV (Windows Hypervisor) only allows for a "virtual switch", not a "hub". (you don't state which Virtual Server you are using). I think your VM would need to somehow override this. –  MikeAWood Jun 12 '12 at 23:59

You are looking to bridge your network.

I have never done this with windows, but I if I go to 'network and sharing center' and right click on a network adaptop it shows a tab 'bridge connection'.

I am already bridging the network. I have tried to be very clear about what I want in my question: I am trying to get hub-like behaviour. –  dromedary Jun 9 '12 at 11:32
    
My excuses. I read your original question twice and still somehow miss interpreted it. I guess extra hardware is not an option? (e.g. mirroring a port via a managed switch?) –  Hennes Jun 9 '12 at 12:10
