I have a home server running ProxMox on Debian Stretch with 3 NICs, 4 interfaces a piece.
Why? Let me explain. I would like to use my ProxMox box to simulate multiple networks, simultaneously to aid in my CCNP studies. My wish is to create virtual bridges and attach one or more VMs to a bridge and connect the corresponding physical interface to a real Cisco switch.
Do I need 12 interfaces? No, but I purchased 3, 4 port Intel NICs for a song and I might as well use them. Of course, I am having tons of trouble getting this to work. At first I thought it was Proxmox, but after a little reflection, I think the problem is that I have multiple NICs and, of course, lots of routing issues. I think the solution lies in creating separate routing instances for each NIC, so they can each have their own gateway.
I’ve seen some generic instructions on how to do this, but, of course, it’s not working. Any hints would be much appreciated
