INetFwV6Connection::ClosePort method
[The IPv6 Internet Connection Firewall is available for use in the operating systems specified in the Requirements section. Instead, use the Windows Firewall API.]
The ClosePort method modifies the firewall configuration for a connection to disallow inbound connection attempts for the specified port and protocol. It is not an error to call ClosePort for a port and protocol pair that is already closed, even though such a call has no actual effect on the system.
This is a state-changing method, and thus is subject to the access control and confirmation UI mechanisms.
