I don't use fail2ban, so I can't vouch that these instructions work. That being said, a quick google search of "firewalld fail2ban" led me to the very first search result of: https://fedoraproject.org/wiki/Fail2ban_with_FirewallD
Do those instructions work?

Hi,
I'm most familiar and comfortable with iptables, and use shorewall on
my firewalls. With fedora23, it appears the default has shifted to
firewalld. This has created a problem for me ever since, particularly
with trying to build a reasonable firewall on my mail servers, as well
as interacting with fail2ban.
We typically offer submission, simap/spop, smtp, http/https, ssh, and
domain services on our Internet servers. We also need snmp and nrpe
for monitoring.
Does anyone have a set of reasonable firewalld rules and understand
how it interacts with fail2ban that they could share? firewalld
doesn't even include all these services by default, so it's necessary
to do it one port at a time...
firewalld just doesn't seem to be appropriate for anything more than a
desktop. I'd appreciate any ideas on how you build a firewall for
fedora servers, particularly as it relates to interoperating with
fail2ban and standard Internet services.
Thanks,
Alex
