      After reading the forum rules, I believe it is prudent for me to make these statements:

      • This is not a homework assignment. None of the courses at the community college I attend part time cover virtualization.

      • All questions I pose are related to a personal project with the goal of increasing my understanding. The project is creating a functional network inside VirtualBox.

      • I am a newbie in both virtualization and networking.

      Here is a list of hardware and software I am using for the project:

      • 2WIRE 2701HG-B gateway

      • host: Lenovo B570 laptop - Win 7 HP SP1 x64, WIFI connected

      • VirtualBox v12.4.12

      • guest: pfSense 2.0.3

      • guest: Windows Server 2008 R2 Enterprise x64

      • guest: Windows 7 Pro SP1 x64

      • guest: Windows 8 Pro x64

      All of the guests have only the barest configurations and have Internet connectivity. Unfortunately, pfSense was the last installation. I did not find out about pfSense until after I began to attempt to establish connectivity.I am trying to draw a diagram of the functional relationships of the NICS to proceed with configuration.

      After reading the VirtualBox user manual, four different pfSense tutorials, and several articles found via Google searches, I am unclear whether the various NICS interact or if they are autonomous outside of the virtual environment. My understanding is that this is considered to be the WAN side of pfSense. Is that correct?

      The NICs I am questioning are the Windows Wireless Network Connection, VirtualBox Host-Only Network, and pfSense. After reading about configuration via the pfSense GUI, I see that further configuration pfSense is with the gateway. Does this mean that I can ignore the Windows and VBox connections for all traffic related to the virtual environment? Is there any reason for me to be concerned with the wireless nature of the host or any relationships between the Windows and VBox NICs? Maybe a better way to ask is does pfSense totally bypass the other NICs?

      After sorting out the WAN(?) side, I will ask questions regarding the virtual (LAN?) side of pfSense. Answers targeted to the newbie will be helpful. I don't mind researching some of the details, but I'm not ready for rocket science yet.

      Thanks for your replies.
