linux router/firewall solution

[Rad_Man]

I have obtained an old 486 PC that I want to use as a firewall/router for the home office(sick of configuring my own PC when working from home with the lappy). I have suse 8.0 server installed, 2 PCI NIC's and awaiting instructions on how to setup the firewall side(so i can still play CS(when i get a chance!!!!)) The setup I want is this

Internet->Cable Modem->router/firewall/SUSE/Domino->Hub->Lan

I have downloaded a program (that fits on a Floppy) called freesco which is very simple and works, but I need to load Domino R6 on the linux box as well to test and develop for work......so i am thinking of staying with suse 8.0 (as domino LOVES IT).  

Thats the crap......now .....how do i do the firewall thing on SUSE? IP masquerading???NAT??? IP Chains.......IPTables.......WTF are they and I DONT WANT TO LOSE THE ABILITY TO PLAY CS through the box either?

ok, so you have a router. that is running NAT right? Why do you need a firewall? A natted router will not let any nasties in anyway.

The way that I'd do it is below (assuming the router only has 1 lan port)

Internet > Modem > Router > Switch > PC's

If the router is a DHCP router (most have) then enable that and all you need to do is plug a laptop into the switch and it'll get all the info it needs to access the internet. It will be secure too unless you already have trojans on your machine, but then your virus scanner will have caught them right

Above is the exact way that I have my home lan set. I also have a laptop that I can plug in either at home or at work with no config changes at all.

Gandy u network guru, the linux box is going to be the router and firewall.

I have one NIC that is a DHCP client(cable modem-dynamically assigned from ISP) and the other NIC is ma LAN which will be running DHCP server.

So you think that I dont even need to start a firewall on the suse box, it is already protected by having 2 NIC's?

for Linux you'll need to consult the oracles

I thought oracle was a database? or did I miss something?

Yep got coyote down and thats cool!!!!!.........happy with that but i have a 6gig hardy doing nothing and suse 8.0 server doing nothing.........who are the oracles? - doggers? -styker? iptables hmmmmm that sounds technical?

[Rad_Man]

I am happy with coyote, easy to configure and works a treat. I will discuss iptables with doggers at the lan feast.
