A person named TD responded to a post that:  

"The best system I have found is First a NAT router with a DMZ set to a
fictitious IP address"

How would I go about doing this?   

I have a Linsys wireless router conected to a cable modem, 2 wired desktops
and 2 wireless laptops in a peer to peer configuration. I would like to make
the firewall and DMZ as secure as possible so I can share resources amongst
the peers with relative security.

Hi

Bear in mind that though the same word Security is used to describe Secure Internet
Connection and Secure Wireless, from a Computer functioning perspective there is No
relation between the two.

Wireless Security has Nothing to do with securing the Internet Connection.

Wireless is just a replacement for a Wire and thus can be intercepted by people in the
neighborhood attaching them self to your Signal and use your LAN and your LAN's Internet
Connection.  To avoid Local Tapping there are Wireless Security measures.  These
measures are unique to the Wireless components, and have to be used even if there is No
Internet Connection.

These short pages describe the basic principles of functional Wireless Security.

Cable/DSL Router Hardware NAT and Firewall/AntiVirus/AntiSpy applications are the ones
that protect the Internet connection from being invaded/infested, and preventing your
LAN computers (Wired and Wireless) from transmitting out to the Internet privileged
information.

All the computers (as a Network) would have basic Internet protection by using a
Cable/DSL Router.  In addition, each computer on your Network that has access to the
Internet should have its own Internet Connection protection regardless of whether it
uses Wire or Wireless.

In addition you should have tools available to clean your computers if they get Infested
with Internet "Junk".
