Cant start firewall

When I try starting in cwp, i get the error

Status: You have an unresolved error when starting csf:
Error: FASTSTART: (DROP no logging IPv4) [] [iptables-restore v1.4.21: iptables-restore: unable to initialize table 'filter']. Try restarting csf with FASTSTART disabled, at line 5790 in /usr/sbin/csf

You need to restart csf successfully to remove this warning, or delete /etc/csf/csf.error

delete /etc/csf/csf.error didnt help

Disabling FASTSTART didnt help

1. Is it VPS or bare metal server ?

2. Do you use some custom kernel ?

It is a VPS

No custom kernel

But I took backup and reinstalled the server now

According to the error the kernel module iptables_filter isn't loaded and OS can't load it for some reason. It could happen if:

1. You use custom kernel without iptables_filter support (Kernel installed from some 3rd party repository or compiled from sources with iptables_filter disabled)
2. Your provider uses OpenVZ/LXC virtualization and the kernel module iptables_filter isn't loaded at main node.

If the problem remains unsolved after the restoration then do following:

Run as root on your VPS:

Code: [Select]

uname -a
ls  /lib/modules/$(uname -r)/kernel/net/ipv4/netfilter/
and show output.

Hi reintalled a new VPS and migrated the accounts before I saw this message.

Thanks for the support
