If I use zopkio, the best would be access SSH direct to the target machine where I need to run the tests. For zopkio, I need to have my SSH KEY on the target machine. As I don't know your network, maybe what you could do is: Via RasperBerry, forward the SSH to the target machine, I will pass-through via your RasperBerry where you can control the access for the rest of your LAN. Another approach could be, two different subnets and a firewall. Or as you said, VLANS.
