Windows Firewall Rules Flashcards
Rule Type
Specifies whether you want to create a program rule, a port rule, a variant on one of the predefined rules, or a custom rule. This selection determines which of the following pages the wizard displays.
Program
Specifies whether the rule applies to all programs, to one specific program, or to a specific service. This is the equivalent of defining an allowed application in the Windows Firewall control panel, except that you must specify the exact path to the application.
Protocol & Ports
Specifies the network or transport layer protocol and the local and remote ports to which the rule applies, as shown in Figure 19-9. This enables you to specify the exact types of traffic that the rule should block or allow. To create rules in this way, you must be familiar with the protocols and ports that an application uses to communicate at both ends of the connection.
Predefined Rules
Specifies which predefined rules defining specific etwork connectivity requirements the wizard should create.
Scope
Specifies the IP addresses of the local and remote systems to which the rule applies. This enables you to block or allow traffic between specific computers.
Action
Specifies the action the firewall should take when a packet matches the rule, as shown in Figure 19- 10 You configure the rule to allow traffic if it is blocked by default, or block traffic if it is allowed by default. You can also configure the rule to allow traffic only when the connection between the communicating computers is secured using IPsec.
