Description:

The keys for downloading new antivirus patterns from the manufacturer Avira expire on September 30, 2023 (only Unified Firewall Full license affected). In order for you to be able to still use the antivirus function as usual after this date, an LCOS FX update is required, which contains new keys. Without an update to these versions, the antivirus function of the Unified Firewalls will block every invoked website from October 1st, 2023, or, depending on manual settings, pass through all data traffic unfiltered.

The keys are updated in the following LCOS FX versions:

  • LCOS FX 10.11 RU3
  • LCOS FX 10.12 RU3

LANCOM Systems strongly recommends performing an update to the versions mentioned above. These are available to download in the Firewall license portal as well as via the Online updater.


You can find information on troubleshooting after the antivirus keys have expired in the following Knowledge Base article:

After the firmware upgrade to LCOS FX 10.11 RU3 or LCOS FX 10.12 RU3, the Unified Firewall does not perform an automatic reboot. The firmware is active immediately.

In the info area of the firewall user interface the previous firmware version is displayed until the admin user logs in again.

In the LANCOM Management Cloud, the previous firmware version is displayed until the Unified Firewall is restarted.
