I think CheckPoint's Firewall-1 is pretty easy to configure and everything.
I'm not saying it's cheap but carry on reading if you're interested in my
�0.02 worth.
Depending on your OS experience you can get it on NT or various flavours of
Unix. Quite a few useful add-ins are available depending on what you want
to do with it, all at a price of course. VPN, secure remote access,
bandwidth management, etc.
As far as a diagram goes.....draw a box for your server with three (or more)
network cards, top, bottom and one side will do for now. Out of the top is
your internal LAN, out of the bottom is your Internet connection and out of
the side is your DMZ where you put all your publicly available servers, web,
ftp etc. Depending on your policy the firewall routes traffic between the
three zones. Will also do network address translation to hide your internal
machines behind one public address.
You specify rules based on whatever services you need eg anyone has http
access to the web server, only internal machines can upload to the ftp
server etc. Anything not specified gets dropped. You may want to split
public servers up by putting them onto different DMZs, just add another NIC
and set up your rules.
For what it's worth.
Ali.

Does anyone have a firewall that they would suggest for a network and a
simple diagram how they have implemented it to protect their servers from
the Net??
Thanks
