Shorewall is what configures your firewall, it's done on the same
computer.

The basic advice is to run something separate as a firewall between the
WWW and you.  If you wanted to be really safe, and run a public web
server, then you'd run the web server on a separate box, too.  

It goes without saying that the web server must be isolated from your
LAN, for that to be of any benefit.  You route connections through your
firewall to it, and allow it to respond back out again.  But you don't
allow it access to any other part of your network.

That way, if someone exploits your firewall (if possible), all they do
is muck up the firewall.  Likewise, if someone exploits the web server,
all they do is muck it up.  They're not able to muck up your other
terminals and servers, because they don't connect to them.
