I actually resolved this...but since its Friday and you might not enjoy the rest of your life without knowing this. :P We are using proxmox virtual environment with a pfsense firewall.....so all my interfaces are created through that......Turns out I did everything correctly I was just being a noob on triggering events.

This way you would be able to sense and drop any packets. And if you want to capture/sniff packets per VLAN, create a port mirroring on a VLAN, then assign that VLAN to the interface where your IDS is plugged to. All traffic will be mirrored to this interface so you can monitor them on your IDS. Are your devices Ciscos or Juniper or mixed environment?

Right now I have snort in a test lab where I have interfaces WAN, LAN....and then my VLANS. My firewall does all the routing and has the vlans setup. So when I go to testmyids.com<http://testmyids.com> and trigger a rule I get the rule triggered on my WAN interface but not any of my VLANs...... Basically what I'm trying to initiate is if a user brings in a byod...I want to be able to detect anything on that machine when it connects to my internal vlan. ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
