(I screwed this up myself before I noticed and fixed it...) I do have the f2b-firewalld package installed yes. Since it was an update - it only replaced same installed packages. A standard install of F2B on Centos7 do also include the f2b-systemd package - which would seem logical. However, after I started using the recidive filter - which IMHO is one of the most important ones - it didn't work. Removing the f2b-systemd package fixed that - and didn't hurt anything else. I have no idea why that is - or if that could be part of the problem with the update here on my system. Allan.
