   Hi Yudhi
  </div>
  <div>
   <br>
  </div>
  <div>
   Do you have a network diagram? Can you share it....you can do so
  </div>
  <div>
   privately to 
   <a href="mailto:amar@countersnipe.com">amar@countersnipe.com</a>
  </div>
  <div>
   <br>
  </div>
  <div>
   If it was a Suricata related issue, you would have no alerts at all. 
  </div>
  <div>
   Therefore it has to be to do with your network. You probably have
  </div>
  <div>
   all systems plugged into a switch with no
  </div>
  <div>
   span/mirror port configuration!
  </div>
  <div>
   Anyway, happy to help further....in fact happy to let you have
  </div>
  <div>
   CointerSnipe for free....you will get 
  </div>
  <div>
   the power of Suri plus rule, asset, event management for free....normally costs a lot of money
  </div>
  <div>
   here is the link if interested
