In this video, I show you what Intra-VLAN blocking is in my own lab environment using a physical FortiGate 60E and FortiSwitch 548D and two hosts connected to VLAN10.
Have you ever arrived at a hotel to find that you are not alone on the network? In that, you can communicate with everyone else inside the same layer 2 broadcast domain? I recently found myself in a hotel where it was extremely insecure so bad the graphical user interfaces for the CCTV system were accessible to all from the guest WiFI.
This feature can stop or limit communication between hosts putting the control back in your hands and rapidly stopping lateral movement capabilities.
It's a widely used feature in hotel or operational technology deployments and a very underestimated feature that works off arp "spoofing".
