Hi all OpenVZ users,

I freshly installed a openvz-7.0.7-336 server, and found that even though I uninstalled the firewalld and cleared all content in /etc/sysconfig/iptables , the iptables still apply some rules to the server. Below is the output that I got. Anyone knows where is the config and how I can remove it completely?

# iptables -L -n
Chain INPUT (policy ACCEPT)
