Angry Sharing internet access with my Windows box


Hey everyone,
I've got a problem that i need some help on.

I have a Slackware box that uses a USB modem (device: ppp0) and i have a Windows box. They are connected by a crossover cable.
I need to allow the Windows box to use the internet. With some help i have written this script:

Quote:

modprobe iptable_nat
echo 1 > /proc/sys/net/ipv4/ip_forward
/usr/sbin/iptables --flush
/usr/sbin/iptables -t nat -P POSTROUTING DROP
/usr/sbin/iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
/usr/sbin/iptables -A FORWARD -i eth0 -o ppp0 -m state --state ESTABLISHED,RELATED -j ACCEPT
When i run this script, my Slackware box can conenct to the internet and ping the Windows box. The windows box can ping the Slackware box, and ping Ip addresses. It can also open an ip address of a website in the browser. But the windows box won't open domain names ina browser or ping them.

For example:
google .com 's IP is 216.239.37.99
If i ping that IP address form my Windows box, i get a reply, but if i ping the URL i don't. Also if i put the IP address in a browser i can se google.com, but if i put the URL in, i can't.

I don't know what to do next, can anyoen suggest what to do?

When you can ping or open an IP address but not the URL, it's a DNS problem. Since the windows box isn't initiating the connection it's not receiving the DNS server addresses from the ISP. You'll have to set them statically. You can get the addresses by viewing the /etc/resolv.conf file on the Slackware box. Then open the network connection -> TCP/IP -> Properties on the windows box and enter those addresses as static.

just trying the same thing, gonna try the script you provided in a min.
My idea to solve your prob:
Have you set your DNS-Server entry on your win box set to the ip of your slack box?
I don't know for sure, just a thought

Someoen told me to set the DNS server for the windows boxes to be the same as /etc/resolv.conf and they are matching. But it doesn't work.

EDIT: also I am using DSL if that makes a difference.

I'm glad i helped you.


I opened the properties for my connection, and checked it and it was typed properly. So i deleted boths the DNS IP addresses, then saved the settings, then i opened it again, and typed it back in and saved the settings. And it worked!

Thanks to everyone who tried to help.
