I have a wired Ethernet port and a wireless port. I have a device connected directly to my PC (running Windows 7) by means of the Ethernet port and the device connects to the Internet, which is available over the wireless network. I can fairly simply bridge the wired port to the wireless port by means of
Control Panel > Network and Internet > Network Connections, selecting the two interfaces and bridging them. This allows the device access to the Internet.
However, I'd like to place a VirtualBox VM in the middle of this bridge, allowing it to sniff (and modify by means of
libnetfilter_queue in Linux) network traffic on the bridge. What is the simplest method of achieving this?
