I'll try posting this question in a very simple way.
I have tested my hardware (modem connection included) with the iso-3.2 CD. Everithing is simply perfect. Internet browsing no problem.

After installing on the HD, no problem for this, I can't get my (dial-up) internet connection back to work. It's really driving me nuts...

PLEASE NOTE: Modem works fine. I can ping my ISP no problem but if I try wathever, it won't resolve the domain names.
If I try on my local network setting up a local web server, LAN connection works.
Have been looking in my iptables to check and tried a /ets/init.d/iptables clear but didn't make a difference.
Can anybody come up with a wise suggestion?
It seems like a small thing I'm overlooking.....
Cheers to all Knoppix/linux users
