ufw's rules is not working
I want to set up ufw on my server, but something wrong here. Even when I trying to block 22 port ssh still working and nothing changing. I have ufw enabled, but nothing works.
You're viewing a single thread.
Make sure you're applying them to the active profile.
how can I make sure?
Are you using the GUI?
no
It's listed as the "profile" in the screenshots you're listing, but that's the ruleset you're altering.
I used nft or iptables, and my interaction with ufw has been sparse, and mostly through the UI, because the rulesets the GUI generates are incomprehensible. There should be a command in ufw to report which profile is active.
I'm going to guess this is a dead-end, since you've been using the CLI and I have to believe it uses the active profile by default, unless you tell it otherwise. However, in the GUI, if you edit rules in a profile it doesn't automatically apply to your current ruleset. And if you alter your current ruleset, it doesn't automatically persist it. So, even if you change a rule on the Home profile, and the Home profile is active, it doesn't automatically get applied to the running ruleset; you have to take another action to apply it.
Mind you, that's all through the UI; I've never used the ufw command line, so this is (again) probably a red herring. I find ufw to be obtuse at best, because of the Byzantine rulesets it generates.
