New in this version

New add-on module: Collax URL Filter

With this update, the Collax URL Filter module can be installed additionally. The new features are activated in the web proxy settings. The module provides 70 categories that can be used for blacklists or whitelists. Filters can be configured independently for different users. Time-based rules can also be applied.

Grommunio: Primary email address from Active Directory

Previously, primary email addresses (used for login and sending emails) could only be assigned using a fixed scheme (login@domain, first.last@domain, or last.first@domain). It is now also possible to use the address from Active Directory.

Important: If this option is enabled later, users will need to log in using their primary email address imported from Active Directory. Email sending will also use this address.

Additional software: Avira replaced by Bitdefender

After Avira licenses expire, they will be automatically replaced by Bitdefender. To ensure a smooth transition, expiring Avira licenses will be proactively replaced with corresponding Bitdefender licenses. The server detects this during its weekly license status check. At that point, Avira filters are automatically disabled and Bitdefender filters are enabled.

System management: Linux kernel 6.6.142

This update upgrades the Linux kernel to version 6.6.142.

Notes

Additional software: Bitdefender - pattern update after commissioning

After starting up the Collax Antivirus powered by Bitdefender module, it may take a few minutes for the current virus patterns to be downloaded. If you click on Update Bitdefender in the virus scanner form during this time, you will receive an error message “Error connecting to server at /opt/lib/bitdefender//bdamsocket: -3”, because the background process has not yet been fully executed.

GUI: Sporadic hangs during running jobs

The progress of configuration jobs is displayed in the top right-hand corner of the web administration. In the case of extensive changes in the network area, especially with country locks (geo-ip), it can happen in rare cases that the job display hangs during activation. As of release 7.2.28, you will now receive the message “Network connection has been interrupted: Messages may be lost until the connection can be re-established.” informs you about such situations.

VPN: Fix for IKEv2 with Microsoft Windows crashes after 7.6 hours

VPN connections with IKEv2 and the on-board tools of Microsoft Windows are interrupted after interrupted after exactly 7.6 hours. The error occurs because Microsoft Windows proposes different algorithms during the IKE re-encryption than during the first connection. The problem can be solved with a registry fix by the value “NegotiateDH2048_AES256” under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters to 1 is set.

Under the following link you will find a REG file (registry entry) that adds the registry key. Collax accepts no liability for system errors resulting from this.
