Should I disable iptables when I'm using csf ?
any help appreciated.
I installed a minimal CentOS 7 version on a development server to virtualize some linux hosts.
In a RHEL training document, the author says:
...run the following command to disable the firewall on the current system: iptables -F
He explicitly uses the word "disable" which to me suggests that it will be simple to re-enable. In reading the man page though for iptables, I see this:
Flush the selected chain (all the chains in the table if none is given).
I'm using the PHPMailer class to send email from an online application, it works fine on development server, and if I disable iptables.
