Can you run

ipconfig /all

on your laptop and post the results.

@x86processor:

No GNU/Linux on laptop. Only Windows XP Service Pack 2.
The route command for windows is "route PRINT" and its output looks fine.

This makes me think that DNS isn't working correctly. What DNS server does the laptop show, if its the IP address of your linux/windows machine then you might not have a DNS server setup on your linux installation. That could cause this problem. Try accessing a website via ip address, eg.

www.google.com 64.233.189.104

Good luck

pinging 64.233.189.104 from laptop returns "Request timed out".
There is no problem pinging it from the PC

Btw the problem with pinging hosts was solved when i disabled the
firewall. So i can ping now google.com from the PC with no problem

SuSE 10.1 as a router

Did you try the 16579.html how-to on the novell site.
Unfortunately, the sysadmin deny me to post the full URL, 'cause I'm posting for the first time. I'll try to write it in other way:
"three times W dot novell dot com slash coolsolutions slash feature slash 16579.html"
it's very detailed and works. The hardware topology is just like yours.

The situation is like this:
I have a PC with both windows and SuSE 10.1.0 installed.
It has two Ethernet Adapters - eth0 (Realtek) and eth1 (Davicom)
In eth0 goes the ISP cable, that provides Internet for my windows and suse.
I use pppoe-start to authenticate with my ISP and make the connection.
eth0 is configured to receive automatic settings through DHCP
eth1 is configured as following:
IP: 192.168.1.1
Subnet Mask: 255.255.255.0
DNS: none
GW: none

On the other hand i have a laptop with windows XP installed and a singular ethernet adapter.
I have a switch that makes the connection between my PC's eth1 and the Laptop adapter.
When I boot my PC in Windows I use Internet Connection Sharing to provide Internet access to the Laptop and it works.

I want to make SuSE route the existing internet connection from eth0 to eth1 and from there to the laptop.

I tried different configs of eth1 in SuSE and echo 1 > /proc/sys/net/ipv4/ip_forward,
but nothing worked.

I cannot even ping my PC's eth1 IP (192.168.1.1) from the laptop when i am in SUSE.
The configuration of the laptop's Network card is like this:
IP: 192.168.1.2
Subnet Mask: 255.255.255.0
GW: 192.168.1.1
DNS: 192.168.1.1

Any ideas :) ?

Thanks a lot, ebrehu !
I'll check this out and write as soon as possible
