How to Turn on Outbound Filtering in Windows Vista Firwall.

Windows Vista includes a two-way firewall that has outbound filtering disabled by default. That feature is turned off as well as hidden in Vista. In fact, it is hidden so well that many users may think that the two-way firewall was yet another feature that was pulled from the final product. While that is true for other features the two-way firewall made it into the final product, you just need to know how to find it.

Very simple, Click on the Start Button and key in wf.msc and hit Enter.
This will bring up the comprehensive Windows Firewall with Advanced Security management interface. Here you will be able to configure rules for incoming as well as outgoing connections.
