Has anyone been able to successfully connect a GNS3 topology to a live network using Windows 2012? I have done it many, many times with Windows 2008, Windows 7, etc, but I recently setup a new GNS3 box that is running Windowsw 2012 R2 and I can create the network bridge using the loopback adapter and the physical adapter, and then I can create the cloud in GNS3 and connect it to that adapter fine, but no traffic is passed. I connect a router to that cloud and assign an ip address in the same network as the network bridge, but I cannot talk to the live network. This has always worked in the past, so I am thinking it must be something to do with 2012.

Any thoughts?
