Hi all. So I'm using ufw on my Debian 11 box, but have been having trouble trying to get it to stop calls from a certain source IP. eg. If I want to cut off an IP address from registration and placing calls via the box, using "ufw insert 1 deny...." doesn't seem to have an effect. I get the idea that this is because the simple way in which ufw manipulates iptables doesn't allow for existing connections to be terminated. How *should* I achieve my aims here?!
