Ya. It may. Based on the default configurations. You can check the present configuration by using the following command sudo ufw show raw. The command will show the configuration of all policy's rules in iptable.


after I remove following rule: 22/tcp (v6) ALLOW IN Anywhere (v6) ufw starts to netfilter.


I managed to get that to work by disabling ufw. $ sudo ufw disable There certainly is a better way if you know one please post it here.


Unless ufw reload and ufw insert output a set of commands that reloads the firewall, piping it to at wouldn't be what you want. Did you mean: echo ufw insert 1 deny from $(tail -n+1 -F /var/log/ufw.log | grep -v --line-buffered '' | sed -e 's/BLOCK/&/g' -e 's/.*SRC\=//g' -e 's/\ DST.*//g') | at now +3 minute echo ufw reload | at now +3 ...


Try this: ufw insert $(sed -n '/ALLOW/{s/^.*ALLOW *\[ *\([0-9]\+\).*$/\1/;p;q}' <(ufw status numbered)) allow from '%IP%' to any; ufw reload
