I've begun looking into network bridging, must most of it is witchcraft for me so far. I currently have the following setup:
I use PC 1 as my development station and PC 2 as a deployment/test station. I'd like to be able to create socket connections from PC 1 to the secondary network of devices represented by the lower LAN (where the switch is) and interfaced through NIC 2. However, I do not want these devices (robots, controllers, etc) to be exposed to the full office network and especially the active internet connection. Both PCs run a mixture of Windows and Ubuntu VMs.
