1. systemctl disable (or mask) iptables.service 2. systemctl enable firewalld.service 3. systemctl start firewalld.service
Make sure you have firewall-config installed for ease of configuration.

Has, the "documentation".

0. yum install firewalld firewall-config 1. systemctl disable (or mask) iptables.service 1a. systemctl disable (or mask) ip6tables.service 2. systemctl status firewalld.service should show enabled 3. reboot
Just did that again on a VM I just updated.....

Tnx Greg, I missed point 1a, but now everything is running smooth: anyway these instructions should easily included in the firewalld documentation. Tnx again

why reboot? this is not a kernel update nor windows __________________
systemctl stop iptables.service ip6tables.service; systemctl start firewalld.service
does the same and is a simple one liner __________________
the big difference is as example on a remote-machine you have good chances that your existing ssh-connection survives this while if something at reboot goes wrong you are locked out

It may have been an aberration.... However, the previous machine I had done this on was running quite a few services and things were "wonky" with connections afterwards. I did not have the time or the desire to investigate so I rebooted. Everything was fine after that.
I think it is fair to say you "should not" have to reboot....but it isn't 100% guaranteed you won't have to.

maybe, but my point is that someone should not blindly reboot before verify that at least a new ssh connection is possible by changes to services which my block any network traffic if things are not going perfectly
genereally: * leave open one ssh connection as safety net * after changes try a new one
this works even if you did make a mistake which causes sshd to refuse start, it does usually not bring down existing sessions and so you can fix the problem

Well, I upgraded from F17 (a box with two virtual machines) and firewalld did not set correct rules for the host (they were and are in iptables - but were ignored). The docs says the good thing is iptables http://docs.fedoraproject.org/en-US/Fedora/18/html/Security_Guide/sect-Secur... In fact we get wrong settings in firewalld (documentation here https://fedoraproject.org/wiki/FirewallD?rd=FirewallD/ ) I am a sysadmin, I manage this crap (seems alpha stage), but other innocent users?

this output is crippled by systemctl (thanks to systemd-guys for a very bad usability at all with their strip and pagers all the time)
"systemctl status firewalld.service | cat" should bring better output
additionally /var/log/messages is normally the place to look
i personally do not use firewalld and will never use it because i write my own iptables.sh scripts since years which are much more powerful and also does not unload modules at changes which is one of the "improvements" of firewalld cuased only by weak implementations of the GUI crap

It is actually a file descriptor leak in firewalld. So not something to worry about. But open a bug report about this specific case. I believe there are existing bug reports on it, but we should look at this case. You should add me as a CC on the bug.
