I'm trying to configure fail2ban and it appears as if it is correctly identifying addresses to ban however it doesn't appear to be successful in banning hosts:

This is Fedora 26

/etc/fail2ban/fail2ban.conf is set to distribution default
/etc/fail2ban/jail.conf is set to distribution default

I've added in to fail2ban.d/local.conf

       [fail2ban]
       enabled = true
       filter = fail2ban
       action = iptables-allports[name=fail2ban]
       logpath = /var/log/fail2ban.log
       # findtime: 1 day
       findtime = 86400
       # bantime: 1 year
       bantime = 31536000
       maxretry = 5

to jail.d/00-firewalld.conf

   [DEFAULT]
   banaction = firewallcmd-ipset
   sender = fail2...@example.com
   destemail = root
   action = %(action_mwl)s

to jaild/10-sshd.conf

   [sshd]
   enabled=true
   # findtime: 1 day
   findtime = 86400
   # bantime: 1 year
   bantime = 31536000



and yes the system is currently setup to accept only public/private key authentication for SSH, I'm assuming that once I get ssh figured out I can get the other services figured out.

Thanks, Jeff
