This applies to OpenVZ on RHEL based Linux systems. This would also be known as the guide on how to make CSF work properly on an OpenVZ container.

You see, with the release of vzctl 4.7 the iptables value in container configuration (–iptables flag to vzctl) became useless. To make matters worse, VZ still accepts the flag and…read more
