Internet sharing wireless

Fayble · 09-17-2005, 12:01 PM

Hi all.

I have a fresh Suse 9.3 installation and I'd like to share my internet connection between server (XP Home) and client (Suse 9.3).

I have Intel PRO/Wireless 2200BG in my Suse notebook, rightly installed.

Altough my Suse notebook is able to connect to wireless LAN, internet connection is not up.

I set up IP forwarding in Microsoft XP.

My configuration:

XP:
Wireless connection:
IP: 192.168.0.2
Subnet: 255.255.255.0

SUSE:
Intel PRO/Wireless 2200BG:
IP: 192.168.0.3
Subnet mask: 255.255.255.0

Host name: linux
Domain name: site
X -> Change host name by DHCP
DNS1: 192.168.0.2
Domain: mshome.net

Gateway: 192.168.0.2
X -> IP forwarding

In notebook, I cant' ping the server (192.168.0.2), and no external IP!

What's wrong?

Well I use FreeProxy as proxy server on XP and configure the browsers to use the XP as proxy. You can try the same.

And this is the output of iwconfig:

What output do you get from:
ifconfig
route -n

Also, what is the IP of your router? Can you ping it?

XP disables ping support by default (internal firewall). You can change it on a per connection basis though. Trying disabling the firewall and see if you can ping.

Try disabling ipv6 as shown here:
http://portal.suse.de/sdb/en/2003/10...illa_ipv6.html

Then reboot.

Fayble · 09-17-2005, 01:53 PM

ipv6 disabled, no success.

I'm not using a router, within XP I have an USB Wireless device. All is good when I boot XP on notebook.

Firewall disabled in XP and SUSE. I can't ping 192.168.0.2.

You had eth1 set up with an ip address but that latest iwconfig seems to show the wireless card as eth0.
