Hi,

I have a Windows Server 2012 server running on my network with two NIC's. The first is connected to a switch which goes out to the internet. The second is connected to a network tap which I have installed on part of my network.

On my server I have Hyper-V whcih has a virtual machine with an IDS OS running on it.

When I use monitor the tap NIC using Wireshark on the Windows Server I can see all of the tapped traffic however when I go into my IDS and add both NIC's I cannot see this traffic. It seems that the tapped traffic is not going through to the virtual machine for it to be monitored.

Any ideas on how to fix this?

Thanks!

Will this work for pushing my tapped data which is currently going to the host through to the vm. From what I saw it the port mirroring it was about mirroring the nic of one VM to another VM.

I'm not sure what tapped data means

read the second link.  Your IDS is in a VM right?

This is the simplified topology. So the issue is I can monitor the tapped data using wireshark on the host however I cannot see this tapped data on the vm.
