I've discussed several details with the firewalld developers (reasonable group of people, btw) and they do acknowledge that firewalld do have some challenges, also in regards to logging. The approach I've recommended have been deployed on two production systems. Btw, the official documentation provides this guidance: <https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Security_Guide/sec-Using_Firewalls.html#sec-Using_iptables> > But remove Anaconda? EEEEK! Anaconda is the installer. To be honest, I've never understood why anaconda needs to be installed on a final production server. The production boxes I have where firewalld is uninstalled also have no anaconda installed. And these boxes do get their proper updates through yum regardless. -- kind regards, David Sommerseth
