LinuxQuestions.org - No data transfer in ADSL under Debian!

Dear Members,
I am using Fedora for several years. I want to use Debian now. I have installed Debian Serge. Everything is working well except the internet connectivity. I have ADSL connection from BSNL (India). It is connected through D-Link ethernet card and router. Under FC5 it is working fine. Following several HOW-TOs, I have configured the network connection, default gateway and pppoeconf, but failed to get the connection up. It seems that the connection with my ISP is always established but somehow fails to transfer data. I am appending the output of some related commands for your analysis. Please, give me your valued opinion!

Thanks,
