Virtualized Stateful Firewall with PFSense.

07/01/2023 – present.

Key Technologies:

  • Level 1 Hypervisor: Proxmox 7.4-18
  • Virtual Machines: PFSense 2.7.2-RELEASE (amd64)
  • WAN IP Pass-through: ATT BG-320 Fiber Router/Modem
  • Stateful Firewall: PFSense 2.7.2-RELEASE (amd64)
  • Intrusion Prevention System: SNORT 4.1.6_17
  • PKI Certificate Management

Accomplishments:

  • Implemented Dynamic MAC based IP address pass-through to ensure that WAN address is consistently assigned to the PFsense firewall.
  • Installed and Configured PFSense Firewall inside of a virtual machine using Proxmox.
  • Assigned primary NIC to PFSense firewall ensuring that all WAN traffic enters and exits the firewall.
  • Configured firewall LAN interface rules to ensure traffic security and to prevent unnecessary IP address ranges from creating inbound connections to the network.
  • Created Management VLAN to allow traffic to Proxmox from specific devices to ensure connectivity should the firewall ever fail or become misconfigured.
  • Installed and configured SNORT IPS package to assist with automated traffic analysis and to prevent network intrusions from bad actors attempting to access my network over WAN address.
  • Installed and configured ACME certificate management environment to create and manage certificates, enabling HTTPS encryption for sites and services on my network.
