PPPoE

[Kim <kim@info.dk>]

Dear Debian Users

I have been working with a network problem the last two days without any 
result. I am posting this here in the hope that perhaps someone else can 
understand what I can't seem to figure out.

I am having to network card in my machine eth0 and eth1. eth0 is used in 
my local network at home and it is not the issue.

eth1 is used to connect to my ISP. My ISP is using FWA technology.

In my /etc/network/interfaces I used to have this:

auto lo
iface lo inet loopback

auto eth1
iface eth1 inet dhcp

auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0

As you can see all very simple.

Normally my ISP would use public IP's but has now decided to move to 
intern IP. This means that my eth1 now gets something like 10.x.x.x 
instead of the public one.

Since I very much would like a public IP my ISP made me a PPPoE 
connection which I have tested on windows XP where it works perfektly.

On debian I ran apt-get install pppoe pppoeconf
I then ran the pppoeconf

In the debian reference I read about using PPPoE and I then changed the 
/etc/network/interfaces to:

auto lo
iface lo inet loopback

iface eth1 inet ppp
provider dsl-provider

auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0

When I use pon dsl-provider and then ifconfig I get:

eth0      Link encap:Ethernet  HWaddr 00:50:04:41:5A:67
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0

          RX bytes:649 (649.0 b)  TX bytes:109 (109.0 b)

All looks fine and ppp0 has got the right IP. If I run route I get:

All looks fine. But when I ping I can't reach anything.

ping www.google.dk
ping: unknown host www.google.dk

ping 212.242.40.3

What am I doing wrong?

The kernel is running with the necessary pppoe driver.

Thanks in advance
