In reply to Mike. @Mike, Thank you for your feedback. We appreciate your insights on AlmaLinux 9.2 and the role of NetworkManager. We'll update the article to include the necessary `nmcli` commands for moving interfaces to the correct zones and highlight the default settings of `firewalld.conf` with `nftables`. Your suggestion about iptables is also noted.

This article is not accurate for AlmaLinux 9.2. NetworkManager is enabled by default and cannot be disabled. Changing interfaces on zones with firewalld does nothing because NetworkManager resets them upon reloading. Your article does not cover the additional nmcli commands needed to move interfaces to the correct zones. You must use both firewalld commands and nmcli con commands to do this correctly. Additionally, you do not explain that firewalld.conf has nftables turned on by default in AlmaLinux 9.2. This can cause issues if you are not aware of this default setting. Although nftables is enabled by default, I switched it to iptables as that is how I configured my previous firewalld setup, even though iptables is deprecated.

@Wendell,

I have included OpenSUSE in the article as suggested by you…

My comment post was submitted twice in error, so I am assuming that is the reason it was not published,

firewalld is the default firewall utility in openSUSE as well as in Redhat/CentOS/Fedora, so I do not understand the reason for not adding SUSE to distributions supported.

Please verify if Tecmint has a strong preference for these now IBM-owned/controlled distributions, over other major distributions like SUSE/OpenSUSE, so that readers are fully aware.

Thank You
