I just bought a 4 port ethernet card on eBay to add to my Proxmox server. I am going to use the 4 port ethernet card on my pfsense server to control my entire network. It will allow me to set up VLANs to separate my different devices. I am planning on using some just for my IoT devices. One network will just be for the servers I have run on the Proxmox server. I will be using two pi-holes for my DNS. I am planning on getting a rack system and mounting my Proxmox server inside of the rack. I first have to get a case and power supply for the Proxmox server before I can make it into a route mount.
