I have suggested firewalld from fedora/RHEL7 for inclusion in openSUSE, as an alternative for SuSEfirewall2 for setups with highly volatile networking.
test rpm packages for openSUSE 13.2 can be obtained here:
firewall-config-0.3.12-1.noarch.rpm
firewall-applet-0.3.12-1.noarch.rpm
You will also need to enable the repository from here to get the dependencies.
