problems with internet connection sharing via a usb modem
On my network I have always used windows xp to share my internet connection to 3 other pc's. But I now wish to switch the "internet server" to linux (opensuse 10.2).
I have managed to setup my modem (alcatel speedtouch 330 usb modem) to connect to the internet, which was fairly painless.
However... I cannot seem to share this connection to any of my other machines on my network. I have sieved through forums and tutorials for well over a week now and haven't had much luck.
I have tried various commands to attempt masquerading but nothing gives.

if anyone can please help me that would be great.
Thanks in advance
To "share" a connection you have to do two things:
Thanks for the quick reply, I'll try this as soon as I can.
At current the other machines are configured manually to connect through a windows xp machine. For example:
is this still sufficient for connecting through the linux box once its setup?
Edit: Maybe I was too hasty. You will need to provide them with addresses for one or more DNS servers it you want them to be able to find anything on the Internet. (Maybe you have already done this and you just neglected to list it.) It might be in a different tab or dialog box from IP/subnet/gateway.
Yeah sorry I do have the DNS also set to: 192.168.0.1
well what does and doesn't work? i'd not be suprised if was actually just dns... you've not mentioned if your main box has a dns server running on it. try pinging google.com by ip address not by dns name for example.
