Proxmox All-in-One

Installing PVE

Start with the port you will want as your LAN port (secondary) from pfSense connected to your network

Install PVE

Fix repositories

• Add "pve-no-subscription"
• Disable "pve-enterprise"
• Refresh updates
• Upgrade

Add a second Linux Bridge

• No addresses or gateways
• Assign your, as yet unused, second physical Ethernet port to this bridge

pfSense

Installing pfSense (a link)

• Build the pfSense VM
  • 8GB drive, 4 cores, 4096MB RAM
  • Use the second bridge (vmbr1) as the first network port & the original (vmbr0) as the second port
  • Configure the pfSense VM to start at boot.
    • Strongly reccomend setting it to boot FIRST & give a startup delay of at least a couple of minutes.
  • Do a BACKUP
  • Open the VM console & pretend you're building a normal pfSense router
  • Once the VM is booted into pfSense...
  • Do a BACKUP
  • Then move on to:

Management VM

• Pick your favourite OS & build a VM (Or... Ya know... Since ya gave that second network bridge a physical NIC (Ya did, right?)... You could just plug a computer in there.)
  • Point its network device at the second network bridge
  • Sign into https://192.168.0.1 (from the Management VM)
  • In Services / DHCP Server / LAN
    • Under Servers, add in your DNS server(s) address(es)
  • Restart networking on the Management VM
  • Feed access to this VM through the pfSense firewall
• Do a BACKUP

pfSense Configuration

• Sign into https://192.168.0.1 (from the Management VM)
• In Services / DNS Resolver / General Settings, under Host Overrides
  • set up a DNS entry for PVE
• In Firewall / NAT / Port Forward
  • set up port forwarding for the pfSense UI (port 443)
  • set up port forwarding for the PVE UI (port 8006)
  • set up port forwarding for SSH (port 22) to the Management VM (if used...)
• Do a BACKUP

Taking it LIVE

Up to this point, your server works fine on an internal network. Unfortunately, as far as the world outside the box is concerned, there are 2 machines there. The Proxmox install AND a pfSense install. They both show up on the network.

So...

Let's fix that.

• Sign into the physical machine (PVE)
  • edit /etc/network/interfaces
    • Change vmbr0 to vmbr1 & vmbr1 to vmbr0
    • Change the address & gateway to those assigned for PVE on the pfSense VM
  • edit /etc/hosts
    • Change the address to that assigned for PVE on the pfSense VM

Reboot the machine

Wait at least a couple minutes for pfSense to fully boot

You can now browse to https://MachineAddress/ to access pfSense or https://MachineAddress:8006/ to access the PVE UI

(Where MachineAddress is the address or name assigned to it by your local network...)
