HELP ADSL and PPPoE

I have just bought an ADSL connection. My ISP is tin.it I am using and Alcatel Speed Touch Home and Suse Linux 7.0 I have had success when I tried running it under Windows, now I am trying to set up the Linux Box. I have set up my linux as suggested in the suse http://sdb.suse.de/sdb/en/html/hoe_adsl_pppoe.html page, but I have not been able to connect with linux. When running pppoed -D -d 9 I see I send an LCP ConfReq, but even if the modem detects something in input, ppp does not receive anything at all and it timeouts. I am sure I am missing something easy, anyone could help me? thanks in advance, Tazio
