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.

Do you have something listening on port 52038 that will respond to a port scan? If not it will report as closed.
It’s my port for wireguard and here what I can’t understand: when I blocking port for this wireguard service I still can use wireguard even if ufw deny it.
Wireguard appears as closed unless it receives the proper packet.
that’s what I looked for
Is wireguard incoming or outgoing from the machine you’re trying to block it on?
outgoing, I guess. I mean, it’s on my vps which I want to use for vpn
Make sure you’re creating a block rule specifically on outgoing in that case.
when I just use
ufw allow [port]command it’ll not work?Outgoing should already allow everything, so no need to specifically allow it.
That’s a website tool checking? It’s almost certainly only going to check TCP, since most of them don’t do anything with UDP because it’s… more complicated.
You may need to find an alternate way to do that, something like iperf or netcat (nc -u ip port)
nmap works great for this traceroute might also be usable vith the -p switch I guess?
