Pfsense Download Iso

Introduction

Proxmox is an excellent virtualization platform based upon Debian Linux. pfSense (and OPNsense) will run nicely in a KVM based VM running on a Proxmox server. This guide will walk you through a simple install to get you started.

First of all, you have to download the pfSense Firewall ISO Image from the official pfSense website. To download pfSense ISO Image, you need to visit, pfSense Firewall. Once you click on the link, you need to follow the below screenshot to initiate the downloading progress. Note: pfSense firewall is based on Free BSD Linux.

Disclaimer

There is a school of thought around if a VM can provide adequate isolation for a Firewall to provide network security. There is a similar school of thought as to if privileged and unprivileged VLAN's should share the same physical links and hardware. Flaws in the underlying software and hardware, as well as mis-configuration, can undermine the security of an entire ecosystem.

This guide should not be considered to endorse the suitability of pfSense running on Proxmox for your systems. You should make this judgement yourself. This guide is also provided without warranty.

Proxmox Network Configuration

For this guide Proxmox has been configured with two bridge networks each connected to an external network port.

Here is the /etc/network/interfaces file:

auto vmbr0
iface vmbr0 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_fd 0
iface eth1.303 inet manual
vlan-raw-device eth1
auto vmbr303
iface vmbr303 inet manual
bridge_ports eth1.303
bridge_stp off
bridge_fd 0

Download pfSense CD ISO on Proxmox

Using a convenient web browser running on your desktop of laptop:

  • Browse to https://pfsense.org/download/
  • Select the AMD64 Architecture
  • Select the CD Image (ISO) Intaller Installer
  • Select a mirror location suitable to your locale
  • Right click on the Download link/button and select 'Copy link location'. This may vary slightly depending on your browser
  • Take note of the SHA256 checksum

Use ssh to connect to a terminal on your Proxmox server and run commands as follows, placeholders are noted with <>:

  • cd /var/lib/vz/template/iso/
  • wget <download link>
  • sha256sum <pfsense-file.iso.gz>
    Check your checksum matches the checksum on the pfSense website
  • gunzip <pfsense-file.iso.gz>

Create the pfSene VM

Create VM Wizard

Log in to your Proxmox server's web interface, then click the Create VM button. Follow the following recommended settings.

  • Node by default will be the Proxmox server you are logged in to. Change this as needed, if connecting to cluster
  • Insert a suitable VM ID, the default will probably be fine
  • Give your pfSense VM a suitable Name
  • Enable the Start at boot check box
  • Optionally, select a suitable Resource Group
  • Optionally, enter suitable Startup and Shutdown options. Most likely this VM should be started first (Startup/Shutdown order value of 1)
  • Click Next
pfSense inherits excellent support for KVM from FreeBSD, so Proxmox can simply consider it to be Linux as follows:
  • Select Use CD/DVD disc image
  • Select Storage as local
  • Select from ISO Image the pfSense iso file
  • The VM Type will be Linux
  • In Proxmox 6.0, the Version will be 5.x - 2.6 Kernel
  • Prior releases of Proxmox, the Version will be 4.X/3.X/2.6 Kernel
  • Click Next

The defaults (show above) are adequate, so click Next

  • The Bus/Device default should be adequate
  • Select suitable Storage and Disk Size to suit your needs
  • We recommend enabling IO thread
    which should improve IO performance by giving the disk its own worker thread
  • Optionally, configure other disk settings to suit your needs or return to them later

For an example set up, the default CPU settings should be adequate. These can easily be adjusted as needed after installation. Click Next

  • Setting Memory to 1024 is adequate for an example installation and can easily be adjusted after installation
  • Disable the Ballooning Device check box
  • Click Next
  • Select from the Bridge drop down, your WAN network bridge
  • Disable the Firewall checkbox, as we do not want Proxmox to apply its own network policy on to our pfSense VM
  • Select from Model the VirtIO option as pfSense has excellent support for this device type
  • Optionally, specify a specific MAC address
  • Set Multiqueue to 8. Which will allow the BSD kernel to negotiate the optimal value with Proxmox
  • Click Add

Review the details selected, ensure that Start after created is not set, then click Finish

Select the newly created VM, then click Hardware, then Add. A pop up will appear.

  • From the Bridge drop down, select your LAN bridge
  • Disable the Firewall checkbox as before with WAN
  • Select from Model the VirtIO option as before with WAN
  • Optionally, specify a specific MAC address
  • Set Multiqueue to 8. Which will allow the BSD kernel to negotiate the optimal value with Proxmox
  • Click Next

KVM presents a tablet stylus pointer device to the Guest OS. This is convenient for Windowing systems but can cause high CPU usage even when idle. pfSense has no Windowing system, so we recommend disabling it.

  • Click Options
  • Double click on Use tablet pointer, a pop up window will appear
  • Un-check the Enabled check box
  • Click OK

Configuration of the VM itself is now complete. Click Start to run the VM for the first time and install the pfSense software.

Proceed as normal with the pfSense installation process.

As pictured, you can use the MAC addresses of the Network interfaces to ensure you assign them to the correct LAN and WAN functions.

Post-Install Configuration

Disable Network Hardware Off-loading

Ensure hardware offload features on the network interfaces are disabled, as VirtIO interfaces have problems with NAT.

  • From the top menu, click System -> Advanced
  • Click the Networking tab
  • Ensure Hardware Checksum Offloading,Hardware TCP Segmentation Offloading, and are Ticked
  • Click Save
  • Reboot the firewall

If not a VM, what should I run OPNense on?

For home, check out the A10 Dual Core or A10 Quad Core appliances in Desktop profile.

For business, check out the A10 Quad Core or the Xeon Quad Core Gen4 as Rackmount appliances.

We are pleased to announce the release of pfSense® software version 2.4.5, now available for new installations and upgrades!

pfSense software version 2.4.5 brings security patches, several new features, support for new Netgate hardware models, and stability fixes for issues present in previous pfSense 2.4.x branch releases.

pfSense 2.4.5-RELEASE updates and installation images are available now!

To see a complete detailed list of changes, see the Release Notes.

Highlights

New Features

2.4.5 adds several new features, including:

  • OS Upgrade: Base Operating System upgraded to FreeBSD 11-STABLE after FreeBSD 11.3
  • Added sorting and search/filtering to several pages including the Certificate Manager, DHCP Leases, and ARP/NDP Tables.
  • Added DNS Resolver (Unbound) Python Integration
  • Added IPsec DH and PFS groups 25, 26, 27, and 31
  • Changed UFS filesystem defaults to noatime on new installations to reduce unnecessary disk writes
  • Set autocomplete=new-password for forms containing authentication fields to help prevent browser auto-fill from completing irrelevant fields
  • Added new Dynamic DNS providers Linode and Gandi

For a complete list of new features, see the Release Notes.

Security / Errata

pfSense software release version 2.4.5 addresses several security issues:

  • Potential cross-site scripting (XSS) vectors in several GUI pages
  • A privilege escalation issue where an authenticated user granted access to the picture widget could run arbitrary PHP code or gain access to pages for which they otherwise would not have privileges
  • Added a fsck run with -z for UFS filesystems on upgrade to address FreeBSD-SA-19:10.ufs
  • Fixed the format of XMLRPC authentication failure messages so they can be acted upon by sshguard
  • Added a custom CSRF Error page with warnings and confirmation prompts before resubmitting potentially harmful data

  • Addressed FreeBSD Security Advisories & Errata Notices

For complete details about these issues, see the Release Notes.

Notable Bug Fixes

In addition to security fixes, pfSense software version 2.4.5 also includes important bug fixes.

  • The default GUI certificate lifetime has been reduced to 825 days, to comply with current standards. These standards are being enforced strictly on platforms such as iOS 13 and macOS 10.15. After upgrading to pfSense software version 2.4.5, a new compatible GUI certificate may be generated from the console or SSH with the command pfSsh.php playback generateguicert
  • Several IPsec VTI fixes, including improved handling of IPsec restarts breaking VTI routing
  • Fixed several issues with custom view management in Status > Monitoring
  • Fixed serial console terminal size handling issues
  • Fixed privilege matching issues which may have prevented some users from accessing pages to which they should have had access, such as the User Manager
  • Fixed an issue when resolving FQDN entries in aliases where some entries could be missing

For a complete list of corrected bugs, see the Release Notes.

Upgrade Notes

IMPORTANT: Proceed with caution when upgrading pfSense software while COVID-19 travel restrictions are in effect.

During this time of travel limitations, remote upgrades of pfSense software should be carefully considered, and avoided where possible. Travel restrictions may complicate any repair of any issue, including hardware-related issues that render the system unreachable. Should these issues require onsite physical access to remedy, repair of the issue may not be possible while travel restrictions related to COVID-19 are in effect.

Due to the significant nature of the changes in this upgrade, warnings and error messages are likely to occur while the upgrade is in process. In particular, errors from PHP and package updates may be observed on the console and in logs. In nearly all cases these errors are a harmless side effect of the inconsistent state of the system during the upgrade from changes in the operating system, libraries, and PHP versions. Once the upgrade completes, the system will be in a consistent state again. Only errors which persist after the upgrade are significant.

Always take a backup of the firewall configuration prior to any major change to the firewall, such as an upgrade.

Do not update packages before upgrading pfSense! Either remove all packages or do not update packages before running the upgrade.

The upgrade will take several minutes to complete. The exact time varies based on download speed, hardware speed, and other factors such installed packages. Be patient during the upgrade and allow the firewall enough time to complete the entire process. After the update packages finish downloading it could take 10-20 minutes or more until the upgrade process ends. The firewall may reboot several times during the upgrade process. Monitor the upgrade from the firewall console for the most accurate view.

If the update check fails, or the update does not complete, run pkg install -y pfSense-upgrade to ensure that pfSense-upgrade is present.

Consult the Upgrade Guide for additional information about performing upgrades to pfSense software.

Upgrading to pfSense 2.4.5-RELEASE

Updating from an earlier pfSense 2.4.x release to 2.4.5-RELEASE is possible via the usual methods:

From the GUI:

  • Navigate to System > Update
  • Set Branch to Latest stable version (2.4.x)
  • Click Confirm to start the upgrade process

From the console or ssh:

  • Select option 13 OR select option 8 and run pfSense-upgrade

Update Troubleshooting

See Upgrade Troubleshooting for the most up-to-date information on working around upgrade issues.

If the update system does not offer an upgrade to 2.4.5 or the upgrade will not proceed, take the following steps:

  • Navigate to System > Updates
  • Set Branch to Latest stable version
  • Refresh the repository configuration and upgrade script by running the following commands from the console or shell:

Planning for the upcoming 2.5.0 release

We are hard at work on the upcoming pfSense 2.5.0 release. Keep an eye on the draft copy of the 2.5.0 Release Notes for information about upcoming changes. 2.5.0 will bring a base OS upgrade to FreeBSD 12.x as well as upgrades to OpenSSL 1.1.1 and PHP 7.3.

The built-in load balancer has been deprecated from pfSense 2.5.0, and all related code has been removed, as it is not compatible with OpenSSL on FreeBSD 12.x. Plan migrations to alternate solutions such as the HAProxy package now.

Please note that pfSense version 2.5.0 WILL NOT require AES-NI. The original plan was to include a RESTCONF API in pfSense version 2.5.0, which for security reasons would have required hardware AES-NI or equivalent support. Plans have since changed, and pfSense 2.5.0 does not contain the planned RESTCONF API, thus the removal of the AES-NI requirement.
