If e-mails are stopped by defined filters for attachments or MIME under circumstances it was not possible to release this e-mail again. The release of such to hold e-mails is corrected with this update.

VPN: Multiple IP Addresse in PPTP connection

If a VPN (PPTP) with several IP addresses was used for a secure remote access, the routing table had been set incorrectly from the third active client connection on. A network connection was thereby not possible. With this update the allocation between devices and IP addresses is being corrected. After the third incoming client connection by PPTP the routing table is correctly allocated with the IP address the device uses. Then the destination network can be reach with the established remote access connection.

Add-on Software: Log Rotation of Collax Virus Protection

The file scan executed by the Collax virus Protection generates log file entries for every search. The rotation of these log files had been irregular up to now. With this update this process is going to be integrated within the system-specific rotation for log files.

System Management: Service Alert when monitoring Webproxy with Nagios

If the system is monitored actively and the Webproxy service is enabled service alerts are reported sometimes, even if the Webproxy perfectly works. With this update the suitable Nagios check is corrected.

System Management: Monthly Log File Rotation is omitted

Up to now the contents of the system log file could be kept for 1 day, 1 week or 1 month. Then the file was saved and moved. To process and search through the system log file the optin to store the file monthly is cancelled and replaced with the weekly rotation from this update on.


Collax SSL-VPN: Behaviour change of objects

With the new version of SSL-VPN the network permissions of all objects will be checked. Thus, the corresponding networks should be added to the group permissions. The port or interface for the SSL-VPN service does not have to be configured with this version.
