After a few days of testing on a local network just using the onboard ethernet port going to a router this is already a heck of a lot easier than the previous imaging solution that I banged my head against for a month. Bare metal is definitely the way to be and I greatly appreciate the insight. I would have torn what remains of my hair out trying to figure out making that work with Virtualbox.
Going from here, trying to get the final set up the way I described in my original post, it sounds like I need to look into the DHCP configuration to move the imaging to the two additional ethernet ports and off eno1, is that correct? Right now I have eno1, enp2s0f0, and enp2s0f1. eno1 will be supplying internet and I presume the other two will be on different gateways reaching out to the switch where the target PC’s will be connected to. Would this be something I can achieve using the built in tools?
