Does anyone have a good readme or anything regarding my upcoming question.

I would like to setup a firewall that would protect 8 internal pc's.
But I would also like to assign those 8 pc's their own public IP.
I've already got the 8 ip's, and a 2.3 SDSL connection.

But I've never configured a redhat box to do this.

Any links to some good reading would be great.

Thanks in advance.

Depending on which version of RedHat you plan on installing ,
there are some good GUI tools that can make life alot easier.
Now, that being said.

You will need to do IP forwarding and Masquerading.

If you want an easy way to setup a firewall. Try Firestarter:

Firestarter
http://firestarter.sourceforge.net/

Shorewall

These GUIs does a sloppy job at my opinion.
Nothing is better than a hand made iptables script.
I suggest you to use nmap to find what ports are open on your box then to use iptables to close useless one.

`man iptables` should give you some good info.
but the best way to start is to examine someone else script, I think.

can Firestarter be used in KDE?

Firestarter is designed for the GNOME desktop, but it works in KDE too.

My fav for the green screen deficient.

FYI- you will most likely only need 2 NIC's on that box. One will be the gateway from your internal network out thru the firewall. The other will be your WAN interface to the SDSL connection. This NIC can have multiple VIP's. Individual NIC's looks cool but VIP's are cheaper. =)

I am not sure of precisely what you intend to accomplish here. Do you mean that you have 8 PC's and a separate (9th PC) firewall, or do have 8 PC's, with one acting as the firewall? If the former, and you are hard-set on giving each box a Public IP, I would suggest that you set up an Invisible OpenBSD Firewall. This could probably be done with Linux, but I am unsure as how to do that. Also, this would eat up a computer that could not access/be accessed from the Internet at all, all comms to the FW Box could only be on the ARP level.

Otherwise, drop 7 of the IP's, and set up IPMasq/Nat on the FW box, and give the rest of the boxes a Private IP.

can Firestarter be used in KDE?

yes. the latest codes from CVS fixed the icon crash on kde system tray.
