OPNsense Logo

OPNsense 18.1 “Groovy Gecko” ist End of Life und wurde durch OPNsense 18.7 “Happy Hippo” abgelöst. Die neue Version erscheint nach ca. 3.5 Jahren nach dem ersten Release.

Damit diese Version installiert werden kann, muss sie über die WebGUI, SSH oder per Installer freigeschaltet werden. Zuvor solltest du unbedingt die Release Notes mit den Änderungen und Anpassungen lesen.

Migration notes and minor incomatibilities to look out for:

  • SSH access is now bound to the “wheel” group which is automatically
    added to “admins” group, which “root” is a member of. “root” is the
    only user that has a default shell, namely opnsense-shell, which is the
    root console menu.
  • SSH access can be set for an arbitrary group as well under System:
    Administration for non-members of “admins” group. However, in both
    cases only SCP works due to a request in the forum to be more proactive
    regarding yielding of shell access rights. If you want a user to gain
    true SSH access you need to change their shell from “nologin” to an
    installed shell in their respective settings.
  • Web GUI HTTPS ciphers have been hardened. To gain access please use a
    recent browser.
  • The authentication fallback for the GUI/system has been removed in
    favour of selecting multiple authentication servers at once. Reassign
    your fallback as a primary authentication method or now use more than
    two methods.
  • It has been found that although WAN interfaces require gateways to
    function, they do not necessarily have to be assigned in single-WAN
    scenarios to avoid interfering with WAN reply behaviour. The “none”
    selection was therefore changed to “auto-detect” to reflect this and
    now is the recommended setting unless multi-WAN is used.
  • In preparation for the firewall alias API the per-item descriptions have
    been removed along with support for the deprecated types urltable_ports
    and url_ports.
  • OpenVPN /31 tunnel network calculation changed to use the first and last
    address as network address and broadcast address do not exist. If you
    are affected, adjust your clients or export their configuration again
    which includes the configuration fix. Additionally, /32 tunnel networks
    are now prohibited.

All images are provided with SHA-256 signatures, which can be verified
against the distributed public key:

# openssl base64 -d -in image.bz2.sig -out /tmp/image.sig
# openssl dgst -sha256 -verify -signature /tmp/image.sig image.bz2

The public key for the 18.7 series is:
