TinyWall is an add-on to the advanced firewall that comes built-in with Windows 7 and Vista. It is designed to harden the firewall protection and provide you with easy to use configuration options that do not require constant pop-ups or complicated rule settings. TinyWall comes with built-in rules that, by default, will block most incoming or outgoing connections. You can use the Whitelist features to manually allow applications, or you can use the learning mode, which will temporarily allow all traffic and automatically add the exclusions for you. TinyWall also comes with an option to unblock all LAN traffic, which will restrict incoming and outgoing Internet traffic according to your settings but allow all local network traffic. This feature can be very handy if you have a lot of applications that communicate across your home or office network.
