I am trying to get my Alienvault sensor to recognize a second interface which is connected to a tap port.
My setup: Physical Hardware / Host system - eth0 on the LAN - eth1 connected to a TAP betwween the switch and egress firewall - VirtualBox
AlienVault sensor - VirtualBox gues - Adapter1 is a bridged adapter attached to eth0 - Adapter2 is a bridged adapter attached to eth1
The problem is that my AV installation does not recognize eth1. The OS sees eth1 on boot; dmesg prints it as and Intel PRO/1000 with connection. I cannot figure out how to make the system see the new interface. When I enter the configuration menus and choose "Setup Network Interface", I do have the option for eth1, however, it states that the interface is down. On the host system, a tcpdump -i eth1 shows that it is seeing traffic.
