firewall-cmd [--zone=<zone>] --list-all

If you leave off the --zone it will take the default zone.

If you want to know what the default zone is:
 firewall-cmd --get-default-zone

iptables-save | less

Or move back to RHEL6:
chkconfig firewalld off; yum install system-config-firewall-tui ; chkconfig iptables on ; chkconfig ip6tables on (and now open common ports; stop firewalld ; start iptables services)

firewall-cmd is provided by the (Fedora) firewalld package:
