This is lab number 4 in this series. If you have not already completed the previous lab, please start at Lab 3: Create a virtual firewall.

  1. Download the current version of the Kali Installer Image from https://www.kali.org/get-kali/#kali-installer-images.
  2. Upload the ISO to your proxmox “ISO Image” storage.
  3. Create a proxmox VM using the following settings.
    • General
      • Node: pve
      • VM ID: 201
      • Name: lab4-kali
      • Start at boot: Checked
    • OS
      • Use CD/DVD disc image file (iso): Yes
        • Storage: Pick the storage path where “ISO Image” are stored.
        • ISO Image: kali-linux-2026.1-installer-amd64.iso
    • Disks
      • Storage: Choose where your VM virtual drive will be located
      • Disk size (GiB): 100
    • CPU
      • Cores: 2
      • CPU Limit: unlimited
      • CPU Units: 100
    • Memory
      • Memory (MiB): 4096 (use 8192 if your proxmox server has at least 16 GB of RAM)
      • Minimum memory (MiB): 4096 (use 8192 if your proxmox server has at least 16 GB of RAM)
    • Network
      • Name: eth0
      • MAC address: auto
      • Bridge: vmbr0
      • VLAN Tag: 20
      • Firewall: Checked
      • IPv4: Temporarily set this to a static IP address that is in your OPNSense LAN subnet.
  4. Install Kali.
  5. Log-in to Kali.
  6. Open Terminal.
  7. Verify network connectivity with the commands ping <OPNSense LAN Interface IP address>, ping <OPNSense WAN Interface IP Address>, ping 8.8.8.8, and dig @8.8.8.8 google.com. If you cannot ping 8.8.8.8 or resolve google.com, do not continue until you fix the problem.

  8. Update Kali software.

     sudo apt get update && sudo apt get upgrade -y
  9. Congratulations, you now have a Kali VM connected to the network through your virtual OPNSense firewall.
