OPNsense Serie 24.1 Savvy Shark veröffentlich mit Hotfix 24.1_1 veröffentlicht

OPNsense Logo

Seit mehr als 9 Jahren gibt es OPNsense. Die Community Edition der Open-Source Firewall OPnsense 23.7 “Restless Roadrunner” ist End of Life und wird durch das neue Release 24.1 alias “Savvy Shark” abgelöst. Highlights des neuen Releases sind:

  • ports-based OpenSSL 3
  • Suricata 7
  • zahlreiche MVC/API Anpassungen
  • neue Konfiguration für ARP/NDP
  • OS-Firewall im Core aufgenommen
  • OS-Wireguard Plugins
  • CARP VHID Tracking für OpenVPN und WireGuard
  • Kea DHCPv4 Server mit HA Support
  • uvm.

Das Update kann direkt über die WebUI durchgeführt werden, was mehere Neustarts durchführt.

Eine Neuinstallation mit OPNsense 24.1 kann ebenso mittels Export und Import der vorhandenen Konfiguration durchgeführt werden. Hier kann die Disk entweder als UFS oder ZFS formatiert werden.

Wer eher in der Konsole unterwegs ist, kann das Upgrade von Serie 23.7 auf 24.1 mittels SSH und der Option 12 im Menü und der Eingabe 24.1 ausgeführt werden.

Vor dem Upgrade sollten die Release Notes gelesen werden, da es Änderungen gibt die ggf. berücksichtigt werden müssen, hier z.B. die Umstellung von der Installation von Squid mit OPNsense zum eigenen Plugin für Squid. Ein Backup ist ebenso empfehlenswert.

OPNsense Hotfix 24.1_1 Release Notes

Migration notes, known issues and limitations:

  • Audits and certifications are requiring us to restrict system accounts for non-administrators (without wheel group in particular). It will no longer be able to use non-adminstrator accounts with shell access and permissions for sensitive files have been tightened to not be world-readable. This may cause custom tooling to stop working, but can easily be fixed by giving these required accounts the full administration rights.
  • ISC DHCP functionality is slowly being deprecated with the introduction of Kea as an alternative. The work to replace the tooling of ISC DHCP is ongoing, but feature sets will likely differ for a long time therefore.
  • The move to the FreeBSD ports version of OpenSSL 3.0 is included and may disrupt third party repository use until those have been fixed and rebuilt accordingly. Please note that we do not vet third party repositories and do not have control over them so their response time may vary.
  • The Squid web proxy functionality moves to a plugin and will no longer be installed by default for new installations. However, if you have Squid enabled the plugin will automatically be installed during the upgrade. There is no code difference in the implementation and integration of the plugin compared to the core version.
