Preparing Proxmox for running TrueNAS

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 (unsafe)

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 network 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 in between them will use this bridge to talk to each other.

1. Select your Proxmox node.
2. Go to System > Network
3. Click Create > Linux Bridge:
4. A popup should appear. Fill it out like so:

   
   The IPv4 we set here is the address at which the Proxmox node itself will be reachable on this bridge. If left empty, it will not be reachable by VMs.
   

5. Click Click Create.

6. Apply the changes:
   

The inter-VM network bridge is now created, and Proxmox itself is reachable on the bridge via the address 192.168.255.10.

Install

 TrueNAS in a VM

Please follow the steps in the TrueNAS chapter and come back once finished.

Connect TrueNAS to the newly created bridge

This step requires that you have installed TrueNAS Scale in a VM.

1. Select your TrueNAS VM
2. Go to Hardware
3. Click Add
4. Select Network Device:
   
5. Select the newly created vmbr1 and click Add:
