[German]Small addendum for administrators of FortiOS systems. A few days ago, a fix was released for a known bug in FortiOS version 7.4.6. A reader pointed it out to me.

The reader wrote in an email: "maybe a little late since the update is already some days old, but maybe you can still save one or the other from an annoying maintenance day."
FortiOS version 7.4.6 deletes rulesets
In FortiOS version 7.4.6, various SD-WAN rules are deleted by the update. This means that you would be offline with the systems as soon as the update is installed. More information can be found on the Fortinet website. The problem is classified as a known issue, but should, in the opinion of the blog reader, receive more attention.
As a workaround, the manufacturer suggests simply creating the rules again manually. Depending on the size of the set of rules, however, this can be extremely time-consuming. The reader writes that he will suspend the update as his installations have the corresponding rules. Shortly before Christmas, the reader did not want to break the network for which he is responsible.
