TIL.
Is this redundant with DNSBL?
Not necessarily. These active firewall tools are much more thorough. They tell you any time an application or service is trying to make a connection to anywhere. Block lists are helpful, but still have gaps. These let *nothing *through unless you explicitly allow it, and ask you clearly and immediately when something that doesn't already have a rule tries.
