SOFTWARE OPTIONS
==================
In order to route between private and public internet
addresses with NT/Win9x, you'll need some sort of NAT,
Proxy or Network Firewall product:

PERSONAL NOTES
• While you don't need to use the Network Connection
Wizard that comes with XP in order to connect your
other Windows clients over ICS, you will not gain
support for those clients for UPnP NAT traversal
unless you do so.
• WinRoute Pro is among the most flexible of the
software NAT/Firewall products...
• Win98SE comes with Internet Connection Sharing, but
it is somewhat inflexible, and all things considered,
its primary benefit may be that it is free.
• The version of ICS that comes with Win2K is quite a
bit better, although you are still limited to using
specific IP addresses for your local network.
• And, lest anyone complain, there's Microsoft Proxy,
but it is not one of my recommended solutions, as
it requires lots more configuration and a heftier
machine than the other solutions mentioned. I'd
take WinRoute Pro (w/HTTP proxy) any day of the
week over MS Proxy 2.0 (or even ISA Server)
• The LinkSys Cable/DSL Router is very powerful and
easy to setup, but sports a less flexible firewall
than WinRoute...
• Nexland has some very versatile hardware
• For better security, go for a device that supports
more than just NAT for the firewall component. The
SOHO Firewall appliances are getting more and more
flexible, and less and less expensive, and in many
cases, they also offer VPN support.
• My favorites (primarily because I own them) are:
LinkSys Cable/DSL Router (4-port)
OpenRoute GT50 Analog Router
The hardware is easy to setup and gets the job
done in short order. Web interface or Telnet for
configuration.
SMC and LinkSys provide integrated Switches with
their products, with both offering a 4-port and
8-port 10/100 Switches, as well as Wireless and
other services.
