This Read Me file is also available under the Help menu of the
IPNetShareX application, so there is no need to save a separate
copy on your hard drive.
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.
IPNetShareX uses unix "natd" and "ipfw". It does not provide full
access to the TCP/IP configuration of the machine or other advanced
features such as a built-in DHCP server. You can learn more about
these tools on our website and in the documentation supplied with
Mac OS X.
2. Features and Limitations
IPNetShareX like other NAT based Internet sharing solutions imposes
some limitations due to sharing a single public IP address. While
basic email, web surfing, and file transfer work well with NAT,
some games and streaming protocols do not.
Unix "natd" operates somewhat differently from the NAT implementation
"natd" does not translate ICMP. This means you may not be able to
ping or traceroute through your gateway. IPNetShareX (natd) may
need to be restarted after disconnecting/reconnecting with PPP if
you get a new IP address. IPNetShareX (natd) supports static Single
3. System Requirements
- Mac OS X
- A connection to the Internet. IPNetShareX can be used with Cable
Modems, xDSL, dial-up modems, and most other data link providers.
- At least one network interface card connected to a network.
It is recommended that two cards be used since this is more secure
in that you are not mixing internal and external data on the same
card. Airport cards, as well as the internal ethernet cards now
shipped on all Macs are acceptable.
4. Installation and Removal
To install or remove the software, simply drag a copy to your hard
drive. If you have selected "Load on Startup" to begin Internet
Sharing automatically each time your machine is restarted, you can
manually remove the IPNetShareX folder from /library/startupitems,
or uncheck "Load on Startup" from the IPNetShareX application.
5. How to Get Started
Refer to IPNetShareX Setup under the Help menu.
