What is a DMZ and can I set one?? Thanks!!

A DMZ is a Demiliterized zone. Which is when you have a firewall in the beguinning of your network then your web server and any other "less secure" components of your network (eg. Wireless access point). Then a firewall behind the web server. Isolating your web server from the rest of your network.
hope this helps  :0)

In an attempt to illustrate this, here's a bit of ascii art:

O--|--O--|--O
A     B     C

Each | is a firewall.
A is the internet gateway to the rest of the world.
B is/are the DMZ server(s)
C is the internal network.

The idea is that all publicly accessable web services are provided by machine B and all the important stuff is kept on the internal LAN (in or around Machine C).
If somebody hacks their way into B then they still can't access the internal LAN due to the extra firewall between B & C.

The easiest way to impliment this with e-smith ,that I can think of', is to have two E-smith boxes like so:

A is your ISP.
One SME takes the part of B in the picture above with the only machine on its internal LAN being machine C.
Machine C is your second SME server and its connects to your local LAN (as per 'normal').

Often its achived by using one firewall  with 3 or more NICs and configuring rules between the interfaces.
Example: smoothwall (RED, GREEN, ORANGE interfaces).
