Internet connection sharing (Fedora-windows)

[solomon]

Hi, can anybody help me to set my small home network, two computers : one is FC9 with internet connection and another one is WinXP. How can I get internet on WinXP box? Computers are connected by cross-cable. Is there any tutorial available? Sorry if there is another thread like this one.

How are you connected to the Internet?

[solomon]

Cable internet, broadband.

[pwca]

Is the cable connected directly to your Fedora box or does the cable connection go to a router first?

Never mind... scratch the above question...

If you have cable internet then you've got a cable modem. Take the RJ45 cable (aka Cat 5,6... ) line coming out of the cable modem and plug it into a router. Now take the RJ45 cable from your Fedora box and plug it into the router. Do the same for your Windows box. Both should now be able to get on the Internet.

I don't have a router, computers are connected directly by cross cable.
I tried to ping each other and it works.

pwca was trying to find out if you have two NIC on the fedora box itself. Or is it wireless base Fedora box.

Hi im really rubbish with networking, but from what i remember if you install firestarter, there is a option in that for connection sharing, i think! but may be wrong its been a while

su
yum install firestarter

how share internet from fedora to windows lan.

rampuji,
Need more details. Are you using Fedora box as a gateway?
Using a router up front?

[metaltux]

use iptables like this
iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE (if your modem is connected to eth1 interface)
echo 1 > /proc/sys/net/ipv4/ip_forward

if your Fedora got for exampls 192.168.1.1 as an IP and the Windows host got this IP 192.168.1.2 so you'll need to set the gateway in the windows host to 192.168.1.1 and set a DNS address that's all

Here's a tutorial that I found with Google "linux box as gateway": http://linuxadministration.wordpress...ernet-gateway/

You might want to refer to it or any of the other 'hits' from Google to see if they make sense to you. As I've mentioned in the past, I haven't used this and can't be of direct help. Perhaps Metaltux will have a chance to explain further.

MetalTux - Thanks a million! I've been looking for that iptables line all weekend

Thanks to metaltux, I am able to get it working by sharing my mobile phone 3G connection to my family with a little tweak. Posted an article here for sharing purpose.
