Firewalld is a front-end for iptables.

Firewalld & Iptables are applications which are used to filter the incoming and the outgoing packets where as iptables are the front end where you are creating the rules

Linux kernel has netfilter module that has filter rules.

iptables is a userland tool that can modify the rules in kernel.
firewalld is a userland tool that can modify the rules in kernel.

You can mess up with both tools; just in different ways.


Yes, you don't have to touch 'iptables', if you have firewalld (which you do have by default).

However, with being familiar with iptables, I use it to peek what kind of rules the firewalld conjures up.

iptables is a userland tool that can modify the rules in kernel.
And the kernel module that deals with these tables is ip_tables. A lot of kernel modules have underscores in their name, but userland tools usually have not.

And then there's ebtables. The userland tool and the kernel module share the same name. Did they forget to make the difference here?
