1. can you ping www.google.com from your WIN-XP macvhine
2. what is the IP address of your WIN-XP machine?

I will enter your MSN address into mine and see what happens BUT please answer the questions I ask you.

Did you configure your Windows box to use your Linux box as a Gateway?
Did you configure DNS servers on your Windows box?

About 3 monts ago, I also helped this guy but he wouldn't answer the questions I posed and was hard work, but managed to get him onto internet from his XP-->Linux-->Internet.

yea, i'd say not enough info...but...anyway, i got mine working real easy (i got help from the forums a long time ago xD)

although....im running a debian system...i dont know how far this will get you since you didnt say your distro..(unless i missed it..)

Code:

modprobe iptable_nat
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward

replace eth0 with the interface that goes to your internet!! hope that helps....when you reboot, you have to type this in again (assuming it works), so you'll have to ask someone how to make startup scripts...i'm still learnin linux too

the Internet connection sharing problem the set

Edit /etc/sysconfig/network-scripts/ifcfg-eth0 -

DEVICE=eth0
BOOTPROTO=static
IPADDR=192.168.0.2
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
ONBOOT=yes
MII_NOT_SUPPORTED=yes

Edit /etc/sysconfig/network-scripts/ifcfg-eth1 - This is the main config file for the second (LAN facing) interface.
It should read :

DEVICE=eth1
BOOTPROTO=static
IPADDR=192.168.3.1
NETMASK=255.255.255.0
NETWORK=192.168.3.0
BROADCAST=192.168.3.255
ONBOOT=yes
MII_NOT_SUPPORTED=yes

/etc/resolv.conf should contain the nameserver address(es) - put the address of your ISPs nameserver right at the top. eg:

nameserver 192.168.0.1

The default gateway and your hostname go in /etc/sysconfig/network:
HOSTNAME=localhost
NETWORKING=yes
GATEWAY=192.168.0.1

We then need to set up packet forwarding:
Put the following command at the beginning of /etc/sysctl.conf

net.ipv4.ip_forward=1

Then 'turn off' the redirection to squid:
Install iptables - type "urpmi iptables" as root, or use the package manager in the start menu or mcc

Add the following code to the bottom of /etc/rc.d/rc.local.

iptables -t nat -D PREROUTING -i eth0 -j loc_dnat

Reboot."""""""""

iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
