Bridged network: Real switch?

[martin_salo]

Hello Forum,

I'm working with VMware Workstation 9.

I use the bridged network adapter to connect my VMs to the same network as the host system. If I monitor with tcpdump the traffic within one of the VM, I can see the traffic of the other VMs too. So I'm guessing vmnet0 is not a real switch like in the picture from the link? How can I separate the traffic? Will a Workstation Update help?

Thanks

Martin

Hi,

The bridge behaves like a hub...

No, an update will not fix this part.

It addresses other areas such as a number of security issues though.

Nope - the vmnet0 is not a switch - it is a hub.

You can set

ethernet0.noPromisc = "true"

in the vmx-file - that will make the vmnet0 to act more like a switch.

On a Linux host you must be root to launch a VM with that parameter.

Thanks, it worked

The traffic from the other machines is now hidden.
