Thanks, I'll try later.
but you could have done that yourself.
No, I could not. I did not, and still do not, know what to search for.
This link is among the first hits searching for "firewalld blocking multicast".
You have to know that it is "multicast".
The address says '224.x.x.x' - 224/4 is all multicast.
Well, yes, but that's something I know only while I'm reading about it, like now. It is not knowledge I have. I confess my ignorance on it. It is not something I thought about when I saw the log entries as something I could google about, so I thought of asking others ;-)
Still, the word "multicast" is not listed in the GUI administration tool to configure the firewalld, so the original question is still valid: how do I enable that traffic using the GUI firewalld administrative tool?
You can edit direct rules also via GUI.
None of the google entries I have seen mention it. And the tool "help" menu is empty, only an "about" entry.
