I have a meterpreter shell to a Mark V behind a firewall. I would like to use it to pivot to another box on the network, however I am not sure if the portfwd command is the way to go. It would be nice, for example, to use the portfwd to access an RDP session on a windows box. The pineapple has two interfaces, one wired, one wireless, both are on the local network. I'm using 4444 on the wired interface as the port to call home to the remote network. I have a machine on the local network that is listening on 3389. Anyone have a clear understanding of the portfwd command they could share?
