Ericsson ADSL modem probs

[bcalder]

Hi there,
I'm running a Knoppix 3.3 HD install (Debian sid), kernel 2.6.6 on my laptop. I used ppoeconf to set up my ADSL connection. Using "pon dsl-provider" I'm seeing a connection, getting an IP address, but I can't ping past the router. The local network I'm seeing fine. This config works under XP.

The line "Cannot determine ethernet address for proxy ARP" seems a bit weird.

I have a Megahertz FE574B PCMCIA NIC and also have a static address. Any help much appreciated!!

The thing that jumps out at me is...

Jun 16 09:22:28 gwlap pppd[1338]: not replacing default route to eth0 [192.168.1.1]

What this would seem to imply is whenever you attempt to connect to some external address (by external I mean not 192.168.1.anything and not 192.168.100.anything), then the tcp/ip stack will push the packets out of your eth0 instead of your ppp0.

I don't exactly know what you might have configured to get into this situation, but getting rid of that default route is most likely the answer to your problem.
When running ppoeconf, try looking for any sort of options that have the words "default route" and try enabling that. Failing that, make sure the option "defaultroute" appears in the /etc/ppp/peers/dsl-provider file.
