[Freeswitch-users] Idiot question regarding ufw

[Alex Lake]

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?!
