VPS iptables rule limit is too low

Posted: 5p in Virtuozzo

VPS iptables rule limit is too low.

You may come across with a “numiptent” error message while restarting iptables or whatever firewall (say csf) you have installed on your VPS. The error appear as follows:

The VPS iptables rule limit (numiptent) is too low (300/450) – stopping firewall to prevent iptables blocking all connections

There is a limit on the number of iptables packet filtering entries for a VPS and if the iptable rules added on a VPS exceeds the “numiptent” set, you will receive the given error message.

To make sure iptables works properly on a VPS, you need to increase the “numiptent” value in the VPS configuration file which is located at /etc/sysconfig/vz-scripts/veid.conf and have to restart the VPS.

or you can increase the numiptent value by using this command from node.

# vzctl set 101 –save –numiptent 400
