New in this Version

Collax Central: New features

With this version, four new features are available for the additional module “Collax Central”. - The information about an available update is now also displayed on the Collax Central dashboard. - You can now code a trigger for a notification in a language other than bash. - The use of newer Javascript features for your own content can lead to problems with some browsers. With this update, the conditions are rewritten so that they are no longer browser-dependent. - For the triggers for a notification, hosts that were already deleted were also offered in the selection of hosts. This has been fixed with this update.

File: Two-factor authentication for logging on to WebAccess

With this release, a method for two-factor authentication (2FA) can be activated for the WebAccess, that in addition to the password of a user asks for a temporary one-time password. The user receives a one-time password through an authenticator app or a security token. In the future, the user will have to enter the one-time password, if 2FA is activated, each time you log on to WebAccess, after entering your login and password. This second level for checking the authenticity of the user eliminates the risk of guessed or spied passwords.

System Management: New Updates available

There will be a symbol on the administration interface about new, available updates.

System Management: Linux Kernel 4.9.220

Issues Fixed in this Version

Collax Gatekeeper: Duplicate IP addresses for ongoing connections

With L2TP dial-up connections with a virtual IP address, it could occur that new connections receive the same IP address as the already connected client. This made the connection of the previous client unusable. This will be corrected with the update.

Collax Gatekeeper: Proposal combinations for IKE tunnels

With certain proposal combinations for IKE tunnels, it could happen that the preferred settings have not been negotiated. This will be corrected with the update.
