+# This requires:
+# ipset (package: ipset)
+# firewall-cmd (package: firewalld)
+#
+# This is for ipset protocol 6 (and hopefully later) (ipset v6.14).
+# Use ipset -V to see the protocol and version.
+#
+# IPset was a feature introduced in the linux kernel 2.6.39 and 3.0.0 kernels.
+#
+# If you are running on an older kernel you make need to patch in external
