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.
Although IPNetShareX does not contain the more powerful features
of Sustworks award-winning IPNetRouter software (such as filtering,
DHCP server, and port mapping), it can still serve many simple network
needs. 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.
IPNetShareX uses unix "natd" and "ipfw". It does not provide full
access to the TCP/IP configuration of your machine, or to other
advanced features such as a built-in DHCP server. You can use our
Search feature (see the left-hand column) to learn more about these
tools on our website, or look in the documentation supplied with
Mac OS X.

Differences between IPNetShareX Pro and IPNetShareX
As of July 1, 2002, we are offering two options with regard to
Use IPNetShareX Pro if:
- you are a commercial organization
- you may need technical support with this software
Use IPNetShareX if:
- you will be using IPNetShareX in a non-commercial installation
- you will not require technical suppport.
IPNetShareX Pro registration is $25.00 and can be immediately ordered
from our online
IPNetShareX registration keys can be obtained at no charge from
our website as described in the included documentation.
In both cases you will need a registration key in order to continue
running the software after the initial 21 day trial period. You
just need to copy and paste the entire XML key file into the registration
edit box and click the Accept button.
- Mac OS X.
- A connection to the Internet. IPNetShareX can be used with cable
modems, xDSL, dial-up modems, or most other data link providers.
- At least one network interface card connected to a network.
We recommend that you use two cards. This is more secure because
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.
Unix "natd" operates somewhat differently from the NAT implementation
in IPNetRouter. "natd" does not translate ICMP. This means you may
not be able to ping or traceroute through your gateway. IPNetShareX
(natd) supports static Single Ethernet configurations.
