Hi, I am very new to networking, virtualization and Proxmox. I am following a course where I am to create 5 host only networks and adapters in VMware. I am successfully able to do this in VMware but I've now been tasked with doing this in Proxmox. How might I achieve this?
 
Hi,

host only networks and adapters in VMware
what exactly is a "host-only" network in VMware? From the name, I guess it's just a isolated network, not connected to any physical layer?

If yes, you can simply create a new Linux Bridge under for the host under System > Network and not assign any bridge ports.
This way, all CTs/VMs using this bridge can only communicate with each other, but not with anything other.

A bridge can be thought of as simply switch, where the bridge port would represent the uplink to e.g. a router.

Yes exactly, it's an isolated network. So the idea is to have about 8 of those isolated networks talking to each other via pfsense routing. I'm trying to simulate a mini security operations center where I can monitor and alert on my network from attacks.
