How do I.....?

[linxnoob]

Here is my network configuration:

Computer running Redhat 7.2
NIC eth0
modem

Computer running Win XP:
NIC

Both are connected to a hub.

I would like to use my Linux machine to dial out for my Windows machine . I have read many posts on how to do this with a cable modem, but I can't get it to work on my setup. I can dial out and surf the web on my Linux machine so I am almost there, I think. I am having trouble configuring my XP machine to "talk" to my Linux box.

Please help.

1st, Try using something descriptive instead of "How do I?" You'll get more help that way.

2nd, lookup gShield. Im using this on my machine right now. works really well w/ 2 nics. Installation is almost like a questionaire.

Basically you will be using your firewall (iptables) to forward all the traffic from your XP box out to the internet.

Your LinBox will act as a gateway. Your dialin will have some ip recongized by the outside world. however your nic will have a 'private' IP. something like 192.168.0.1

then you will set your XP to use it as the gateway but make sure to use a real DNS server. You should set your Linux and XP boxes up so they can at least ping/share files between each other first, and be able to dial out. then setting up gShield will be a snap.

Hope that helps.

I used neat to configure eth0 to 192.168.0.1 and the subnet mask to 255.255.255.0. I left the gateway address blank since I dont know what it is.

I used 192.168.0.2 and same subnet mask on XP machine. For the gateway I used 192.168.0.1. For DNS, I used 192.168.0.1 too. What should I be using for a computer name and workgroup in XP.

How do I use a real DNS server. Where do I get that IP from?


As you can see I am new at all this. Please be as detailed as you can.

Thanks again.
