Situation: We usually perform penetration tests from Linux machines connected to the clients local network. However for this test the client wants the start point to be a windows machine and has thus provided us with remote access to one of their windows workstations(To simulate phishing).
I know there are windows alternative options, but what i'm wanting to do is find the best way to "fully" join my linux machine in our office to the network that the windows machine is on.
My current thinking is a OpenVPN connection via a reverse SSH tunnel. Will this be enough to run tools such as Responder and Layer 2 MITM attacks? I'm open to any alternative methods of joining the linux machine to the remote network.
