Why each option
Windows Firewall uses the term 'exception' to describe a rule that permits a specific program or port to communicate through the firewall, overriding the default block behavior.
In Windows Firewall terminology, an exception is an entry in the firewall rule set that explicitly allows inbound or outbound traffic for a named application or a specific TCP/UDP port number. When a program or port is added to the exceptions list, the firewall permits matching packets through rather than blocking them. This is the standard mechanism used in Windows XP SP2 through later versions for user-configured allow rules.
Pass-through is not a recognized term in standard software firewall configuration vocabulary.
Port-forwarding is a router or NAT feature that redirects traffic from one port or IP to another and is not a firewall allow-rule concept.
Punch-through is not a standard or official term used in software firewall rule management.
