CSF won't start - iptables error

Hello,

after a server reboot this morning I've noticed that the CWP dashboard shows the firewall as being switched off. The firewall manager shows the status "Error: iptables command [/sbin/iptables -v --policy INPUT DROP] failed, at line 1365 in /usr/sbin/csf".

When trying to manually start csf I get a lot of "iptables v1.4.21: can't initialize iptables table `filter': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded" errors.

Any ideas what I could do to solve this?

if openvz server contact server provider with that error.

I was able to fix it myself. Reinstalling the kernel did the trick.

Code: [Select]

yum reinstall kernel

and by the way it seems to be kernel 3.10.0-1127.10.1.el7 that breaks something. When manually selecting this kernel from GRUB2, I run into the same problem again. When choosing 3.10.0-1127.el7.x86_64 (without 10.1) everything works smoothly.

This is some incompatible between CWP and CSF firewall? There is no way to check this before update the csf firewall?
