The application I am currently using is a firewall rule that matches the input chain and the noobs address list. The complication I have is that if they have already established a connection with something on my NAT’ed servers it isn’t blocked.
I then attempted to block this traffic by duplicating the rule and then made it match the forward chain, but it doesn’t seem to be working, as in not matching any packets. The rule was right below the first one.
Does anyone know what I have done wrong?
