Make sure all the modules for iptables are properly loaded, and you have all the options about iptables in your kernel compiled or installed as a modules. It works for me.

Fresh installs of Redhat 7.1 load both ipchains and iptables. Ipchains is loaded first which causes iptables to give these errors. I believe if you remove the ipchains module, and start iptables, it will solve your errors.

Good luck.
