From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I meant firewalld im sorry
Use UFW - uncomplicated firewall. Some distros install it by default. Its very easy to use whereas other firewalls are super complicated
I currently use firewalld is their a diffrents in terms of security ?
I dont think so. Both UFW and firewalld are just frontends - they don't actually do any work themselves. That is all handled by the iptables or the newer nftables kernel modules inside the kernel itself, the major difference will be in what rules they create but both should be able to create the same rules for either of these kernel APIs. UFW is what ubuntu uses by default I believe and firewalld what a lot of other distros use by default.
Thanks this was a very usefull anwser!!!
No, only the configuration syntax is different. If you know what you're doing in configuring them both are fine.
They're pretty similar but firewalld allows more complex rules without resorting to plain iptables syntax. Try both and see what you like better.
