From the developer:
IPNetShareX is a small program designed to give users graphical access to Mac OS X's Network Address Translation (NAT) services without having to use the command line. NAT is a protocol used to share a single internet connection among multiple computers without requiring a dedicated hardware router. IPNetShareX can be used as an alternative to the basic Internet sharing feature of IPNetRouter.
