Objective

I can't currently add VM's to my Proxmox because there's no network bridge. We're going to configure the bridge.

Housekeeping

  • Proxmox docs say to make sure that ifupdown is installed if running Proxmox on Debian.
  • sudo apt install ifupdown2 -> Output: Already installed
  • Naming Conventions
  • en* -> Ethernet Device (for all Installations after 5.0, previously eth[N])
  • vmbr[N] -> Bridge
  • Bonds: bond[N], where 0 ≤ N (bond0, bond1, …) < * VLANs: Simply add the VLAN number to the device name, separated by a period (eno1.50, bond1.30)
  • Bridged Connection
  • In a Proxmox VE server in a private LAN, using an external gateway to reach the internet a Bridged model makes the most sense. This is also the default mode on new Proxmox VE installations.
