You can use Windows Firewall with Advanced Security to specify port numbers or protocols in connection security rules, as well as ranges of port numbers.
In previous versions of Windows Firewall, you had to use the netsh command-line tool to perform this action. Creation of IPSec connection security rules has been simplified with the use of dynamic encryption.
When securing tunnel-mode connections, you can specify the authorized users and computers that can set up an inbound tunnel to an IPSec gateway server. You can specify that an outbound allow rule can override block rules when secured with an IPSec connection security rule.
Additional options have been added for configuring authentication for an IPSec tunnel-mode rule. A new main mode configuration capability includes additional configuration options for specific origin and destination IP addresses or network location protocols. Network connections matching a main mode rule use these settings rather than the global defaults or those specified in connection security rules.

For example, when someone calls your Skype and your computer rings, an inbound connection is established to the Skype program. An outbound connection represents a program on your computer trying to reach to a remote computer to exchange data. For example, when you visit a Web site with your browser, an outbound connection is established from your browser.
Obviously, inbound connections are more dangerous than outbound connections. Allowing all inbound connections is like leaving your front door wide open to your house.
