Hi,

I am currently running a network for my company which comprises the
following:

3 x Windows 2000 Servers in a domain
A Cisco router using NAT connecting us to our ISP.

These are in the following setup:

ROUTER
192.168.254.254

DOMAIN CONTROLLER (Office File Server - Email Server)
192.168.254.1

DOMAIN CONTROLLER (Application Server)
192.168.254.2

TEST SERVER
192.168.254.3

Currently, our web site is hosted by our ISP. We use our office file
server as our email server.

We currently have 3 clients, and our aim is to host a web server
internally, for each of these 3 clients and also host our own web
site. We will use our Test Server for one of these, and will purchase
a further 3 servers.

We would like to be able to access each of the 6 servers internally.
However we would only like each external client to have access to
their own server externally. They should also have their own FTP area
on their own server.

What should the correct type of setup be? I am interested in a
hardware firewall, where it should be sited, and how it should be
configured. I am very new to this area, so would really appreciate
some assistance in this area. Also any basic information on hardware
firewalls and basic configuration information eg websites would be
appreciated.

Many thanks, and apologies for the long post!

Martin.
