Network configuration

There is various versions of network configuration on this page:

  • Default networking (unsafe);
  • TrueNAS-ready networking (during bootstrapping or disaster recovery);
  • Routed networking (safe).

Default networking

TrueNAS should not (and largely cannot) run in this configuration.

By default, Proxmox creates the vmbr0 bridge to connect Proxmox itself to the internet.

If the machine is physically the first device connected to the internet, you should move on to the more advanced networking steps as soon as possible.

In this scenario, the network setup is as follows:

  • The bridge vmbr0 exists by default:
    • It's used to connect both Proxmox itself and all VMs to the internet.

Continue to the next section.

TrueNAS-ready networking

This is required for running TrueNAS.

Prerequisites

Your setup before is expected to be:

  • The machine is physically connected to some form of upstream internet;
  • The only network bridge that currently exists is the default vmbr0.

Steps

Creating the inter-VM bridge

To allow virtual machines to communicate safely, we will be creating a new bridge vmbr1. VMs that require direct communication with each other with no additional routing will use this bridge to talk to each other.

 

Routed networking

You must have completed all previous steps.

TrueNAS is required to perform these steps.
