Need help with ADSL

I can't configure my KNOPPIX to work with ADSL. I have to network cards, one for the INET and one used as a gateway router. When I run the ADSL/PPPoE Config. Tool I get this error message:

"Sorry, I scanned 2 interface(s), but Acess concentrator of your provider
did not respond. Please check your network and modem cables. Another
reason for the scan failure may also be another running pppoe process which controls the modem."

I live in sweden an my ISP is Telia.

I also tried to run the Network Scan program (or what ever)... I use it on both NIC and It asks me if I want to use DHCP broadcast and I pressed yes. After approx one minutes I get a failure message that says something like can't connect to something.. bla... bla ... bla

So could someone help me fix my crapy Connection...

BTW I run KNOPPIX from cd, and not from HD and my HD partion is NTFS (if that helps).
