Fedora-21 firewall advice?

[Timothy Murphy]

Am I right in thinking that there are two entirely different
versions of firewall in Fedora-21? I've been looking at

<https://fedoraproject.org/wiki/FirewallD#Dynamic_firewall_with_FirewallD>

and it seems I have to choose between systemd (dynamic) firewall
and iptables (static) firewall?

I'm presently using shorewall with iptables.
Can shorewall be used with firewalld?

I'm surprised that I have never seen an article starting
"In Fedora 21 you will have to choose between firewalld and iptables."
Or have I completely misunderstood the situation?
