These "built-in" services cannot have their settings changed, and also cannot be deleted. OS X will not allow those ports until Personal File Sharing is enabled.

To increase security, ports that have a corresponding service in the Services tab of the Sharing control panel cannot be allowed until that service is enabled. OS X includes a number of default ports for things such as viewing web sites (port 80), SSH (port 22), and many others. When you set up your firewall, you need to decide which ports you will need to keep open. OS X's implementation allows you to close the largest number of potentials entries with the least amount of setup. This is different from some firewall products, which by default allow all ports and restrict certain ports. Mac OS X's firewall works by allowing certain ports to open. By limiting the amount and type of traffic that is allowed to pass on your computer, you can eliminate many of these methods. The main purpose of this is to stop hackers from gaining entry into your computer through various connection methods.
