Title: Cannot enable Firewall
Post by: gailclark80 on March 17, 2026, 02:41:19 AM

I ran [root@server ~]# csf -e
and it shows the following error

Error* The path to iptables is either not set or incorrect for IPTABLES [/sbin/iptables] in /etc/csf/csf.conf at /usr/local/csf/lib/ConfigServer/URLGet.pm line 39.
Compilation failed in require at /usr/sbin/csf line 34.
BEGIN failed--compilation aborted at /usr/sbin/csf line 34.

How should I fix it?

Please advise the following:

What distro are you running CWP on?

New or Existing installation?

What csf version? [csf -v]
