DNS Proxywall

DNS Proxywall: A friendly piece of software that lets you monitor DNS caches and save them as files on your computer

DNS Firewall is a functional and intuitive application that lets you view all communication between your computer and DNS server displaying information in real time.

The program can apply a user-defined collection of filters to monitored communications, allowing you to block certain domains. Furthermore you can manually create a list of domains that the tool should never block.

On top of that, DNS Firewall enables you to select a DNS proxy, and it is possible to set the app to deliver audio notifications when performing or blocking queries, as well as when responses are successful or unsuccessful.

The application also lets you pause the cache as needed and playback or clear the recorded cache.
