Allow vs . Block Rules
Both inbound and outbound firewall rules can be configured to either allow or block traffic that matches the filtering conditions specified in the rule. For example, The properties of the Remote Assistance (TCP-In) rule for the domain and private firewall profiles. By default, this predefined rule is configured to Allow The Connection, making it an allow rule. This means that if Windows Firewall with Advanced Security is processing an incoming packet and determines that this rule applies to the traffic, the packet will be permitted to enter the TCP/IP networking stack of the local computer. By contrast, if you change this rule by selecting Block The Connection, then when Windows Firewall with Advanced Security is processing an incoming packet and determines that the rule applies, the packet is prevented from entering the networking stack of the computer.
