REDHAT 9 BEEN THE FIREWALL AND ROUTER IN MY LAN
Posted on 2003-12-08
I just set up my home network and I need some help i order to have a router and a firewall up and running.
I will describe in detail how this simple network has been setup.
1. I have three computers. One is running redhat 9 and the other 2 are running windows XP.
2. I have a HUB.
3. The computer using LINUX has 2 ethernet cards.
I get my ip address dynamicaly, but usually it is always the same, and that is not a big deal at this point.
How it works?
Well, the internet cable comes from my ISP provider and it is pluged in the HUB. From this HUB I have three extension, one goes to the LINUX box, the other to the windows computer and so does the third one.
* What do I want to do ?
Simple, in stead of having the internet cable going directly into the HUB, I want to plug this cable into one of my ethernet cards in my LINUX machine.
Once thi is done, then I will take another cable and plug onw side of it into the other ethernet card in my linux machine, and the other site will go into the HUB. From this HUB the two computers running windows will be plugged as it is now.
This means that my KINUX machines is going to be my firewall and my router, but I do not know how to do this.
Please refer me to a good tutorial or tell me how to do this, but please don't be smart and say something like "Bridges is what you want".
I hope you can help me setting up my home network, having LINUX as the main firewall and router.
