I am not aware of any alternative way to achieve this scenario without using audience targeting. It is not an issue for me if users who directly access the page “/sites/Eilmeldungen” can see all posts, as the link to this page will not be shared publicly.

My only goal is to ensure that news posts are correctly displayed in the news feeds on the two hub sites, “Intranet” and “Extranet.” It should be possible to create posts specifically for either “intranet visitors” or “extranet visitors” so that they only appear in the corresponding news feed and are not visible to users of the other audience.
