24.03 New Features and Changes

This is a regularly scheduled software release including new features and bug fixes.

Consult the Upgrade Guide before proceeding with any upgrade.

Warning

Before attempting the upgrade, check the list of current ZFS Boot Environments (System > Boot Environments) and clean up any older entries to ensure they do not consume space which may be needed during the upgrade. See Check and Clean Up ZFS Boot Environments for details.

General

  • pfSense Plus software version 24.03 makes sure the user changes the admin account password in the user manager away from the default value. It also ensures that the password is not set to the same value as the username. This validation happens during the setup wizard for new installations, on login and loading any GUI page for existing users, and at the console/shell menu.

    Most users will not notice any difference since they have likely changed their admin account password to a secure custom value in the past.

    Resetting the password via the console menu now prompts the user to set a custom password rather than using a default value.

    Note

    These restrictions apply to all accounts. Users are also prevented from changing passwords to problematic values.

  • The default State Policy has been changed from Floating to Interface Bound for increased security. However, Interface Bound states may have issues in certain cases with IPsec VTI, Multi-WAN policy routing (route-to), reply-to, as well as with High Availability state synchronization (pfsync) on non-identical hardware.

    The default policy can be toggled back to Floating using the State Policy option under System > Advanced on the Firewall & NAT tab.

    There is also an option to override this behavior on a per-rule basis in the advanced options when editing a firewall rule.

  • This release adds support for Packet Flow Data export via pflow in PF. This feature natively exports NetFlow/IPFIX flow data to an external collector.

    See also

  • This release includes support for enhanced gateway recovery “fail back” by optionally clearing states from lower tier gateways when a more preferred gateway recovers.

  • pfSense Plus software can no longer run on AWS “.nano” size instances as they lack sufficient RAM to upgrade properly. Attempting to upgrade a “.nano” instance to pfSense Plus software version 24.03 will fail before the upgrade is performed.

    Migrate the instance to a “.micro” or larger size before attempting to upgrade, or redeploy instead.

  • This version requires an updated boot loader, which is automatically handled by the upgrade process for nearly all cases. However, there may be some edge cases where the automatic update does not update the loader currently used by the device. For example, if there are multiple unmirrored disks and the BIOS/EFI Firmware is not booting from the disk containing the updated loader, but an older unrelated installation on a separate disk. One particular case where this can happen is when there is a previous installation to MMC which has been followed by an installation to an add-on SSD without clearing the MMC contents.

    In these cases the best practice is to wipe the unused disk so it cannot interfere. See Troubleshooting Multiple Disks for details.

Minor Revision

Devices running pfSense Plus software version 24.03 may be seeing a “24.03_1” update available which is a very minor revision made to address a missing dependency on 64-bit ARM devices (https://redmine.pfsense.org/issues/15433). The revision is kept the same on all platforms for consistency.

Upgrading to this version is safe, but not necessary at this time unless users are running on 64-bit ARM devices and want access to S.M.A.R.T. disk data (e.g. Netgate 2100 devices which have an add-on SSD).

Using the GUI or pfSense-upgrade from the console or shell to upgrade from 24.03 to 24.03_1, the device will want to reboot, but in this case that is unnecessary. However, doing so is harmless except for the minimal downtime involved in the reboot during that upgrade process.

Manually updating from the shell via pkg update; pkg upgrade will pull in the new revision and fixed dependency as needed. Run those commands from a shell prompt and confirm that the proposed changes are OK. No additional action is necessary.

Devices which have not yet upgraded to 24.03 or those installed fresh via the Online Network Installer will obtain the latest version automatically and do not require any additional action after upgrading.

Hardware-Specific Notes

Warning

Support for the EOL Netgate 3100 device architecture, armv7, is being phased out upstream in FreeBSD. While this release still contains base system functionality for the Netgate 3100, several packages are unavailable as they can no longer build for that architecture. The list of packages unavailable for the Netgate 3100 now also includes Suricata, Squid, and squidGuard.

Users who wish to continue using those packages on a Netgate 3100 should not upgrade to this release.
