We have 2008 R2 Server that is the main Server for PRTG at the Central HUB. We have six Network cards on the Server. I would like to use to of these network cards to send SPAN \ Mirror traffic to. One of the connections will be to packet capture the Internet traffic and the other will be for our MPLS traffic. The only NIC card that I am able to see if the NIC card the is connected to our core Switch that has the actual IP address of the PRTG Server. The NIC's that I have in Promiscuous Mode where the SPAN \ Mirror traffic is being sent to will not show up in PRTG. Any suggestions?
