Set up a new system service port

You can set up a new system service port on your PC that you can open or close, to allow or block remote access to your PC. You can also modify the incoming and outgoing network access information for an existing system service port.

If your PC has a program that accepts either web or FTP server connections, the PC sharing the connection might need to open the associated system service port and allow forwarding of incoming connections for those ports. If you are using Internet Connection Sharing (ICS), you also need to add a Home PC connection on the Connections list. To learn more, read Add a PC connection.
