Configuring system service ports
System service ports can be configured to allow or block remote
network access to a service on your computer. These system
service ports can be opened or closed for computers listed as
Trusted, Standard, or Public in your
Networks list.

associated ports:

System service ports can also be configured to allow a computer
to share its Internet connection with other computers connected
to it through the same network. This connection, known as
Internet Connection Sharing (ICS), allows the computer that is
sharing the connection to act as a gateway to the Internet for the
other networked computer.
Note: If your computer has an application that accepts either web
or FTP server connections, the computer sharing the connection
may need to open the associated system service port and allow
forwarding of incoming connections for those ports.
