I got the following error while starting csf from the vps.
“The VPS iptables rule limit (numiptent) is too low (119/128) – stopping firewall to prevent iptables blocking all connection”
The reason is By default, containers are only allowed to create about 100 or so iptables rules, which will cause a major problem and prevent CSF from running because it will create more rules than that. You can increase the value using the following.
vzctl set VEID –numiptent 1280:1280 –save
