I have a question about fail2ban behavior and hope you could help to clarify. thanks in advance.
So I had fail2ban running on a CentOS 8 server successfully but it just occurred to me recently that on this centOS server, it uses firewalld and has no iptables service. I know some documentation suggest to use firewallcmd-ipset, but on my jail.conf, the banaction is to use "iptables-multiport" and it has obviously been working correctly. Maybe firewalld read iptables rules in the background? Any explanation of this is greatly appreciated.
