In this post I describe how to configure a Hyper-V virtual network switch into promiscuous mode. This mode allows you to monitor external traffic, eg. Needed for Microsoft Defender for IoT.Assuming you already created an dedicated virtual network switch, you have to run these four steps.
- Turn off Allow management operation system to share this network adapter
- Turn off Enable virtual machine queue
- Set port mirroing mode to Destination
- Configure the Ethernet Switch Port Security Settings
