4.7.2 Failure to insert ip_tables module

The ip_tables module fails to insert with an 'Operation not permitted' error. This issue, which is currently under investigation, can occur if SELinux is in enforcing mode. A workaround for this issue is to set SELinux to permissive mode, which can be done either temporarily by running setenforce 0, or permanently by editing the /etc/selinux/config file and then rebooting.
