I have installed plasma-firewall to get the item directly on System Setting and is Active, I have UFW installed.
Seems ok but if I put on Konsole the command sudo ufw status it is inactive.
There is something strange, plasma-firewall active but the core firewall that is ufw in not active.
Probably better uninstall plasma-firewall and stay with ufw making it active but before this action I want understand why this difference between plasma-firewall and ufw
Thanks
Ok, so to be safe I will uninstall plasma-firewall and use GUFW, active UFW and forget it. Because plasma-firewall has wrong info, there are 2 month I thougth fw is active but is not
