New in this Version

Collax Central: New features - Own content and notifications

Auf einem Central-Server kann mit den beiden Funktionen „Auslöser“ und „Benachrichtigung“ für ausgewählte Ereignisse auf Central-Clients eine Benachrichtigung versendet werden. Hierzu beobachtet ein Auslöser die einlaufenden Daten der Central-Clients und reagiert auf ein vorgegebenes Muster. Ist die Bedingung des Auslösers erfüllt und für ihn eine Benachrichtigung konfiguriert, werden die angegebenen E-Mail-Empfänger über das Ereignis informiert.

With this version, two new feature pairs are available for the additional module “Collax Central”.

Individual information can be collected on a client and displayed on the server in its own box.

An observer can be scheduled for events. Once a condition is met a trigger is generated. E-mail notifications can then be defined for the triggers.

Misc: New Supportfeature - Post-Config

With this version a new support feature is available under the name Post-Config. With Post-Config changes to the configuration of the server can be made, which otherwise could not be carried out via the administration interface. This is the case if the behavior of the server in a different situation or a bug fix must be imported. If necessary, Collax Support will help you.

VPN: pass MTU to ipsec-route

No MTU is set within the tunnel for incoming IPSec connections with a virtual IP address. This can lead to fragmented IPSec packets, which in turn can cause further problems. This update ensures that the value include into the connection establishment.

VPN: Duplicate IP addresses for ongoing connections

With long-established IPSec dial-up connections with a virtual IP address, it could occur that new connections receive the same IP address as the already connected IPSec client. This made the connection (more precisely: the ESP connection) of the previous client unusable. This will be corrected with the update.


E-Mail: Avira AntiVir prior Version 7.1.6

From Avira, an automatic update of the core components of Avira has been carried out. In this context, a new dependency of the libraries has been added, the next time the virus scanner is not started can be resolved. The result is that the virus scanner does not work during a reboot or configuration change is restarted. For security reasons, emails will no longer be delivered. To solve the problem, please update your server to version 7.1.6. Note: As long as the virus scanner is not restarted, it works in its entirety.
