Hi all,

First, let me thank you for all the answers I already found here
But I'm really stuck right now.

I'm trying to connect to internet with my freshly installed Debian (still at 2.2 kernel).

My ethernet cable modem is on eth0 and is supposed to be forwarding dhcp requests to my isp (Noos). It works fine under WinXP on my other box.
What I did first, after getting the right module for my nic, is :

something like
# /etc/network/interfaces

iface eth0 inet dhcp


# ifdown eth0

# ifup eth0

I get something like "every thing is fine", but then I get my prompt back 50 seconds later and get the ip 192.168.0.247. I don't think my isp's dhcp would have given me a private ip. Well of course I can't ping anything (100% packet loss).

I can ping and telnet my PCs on my lan (well, my direct RJ45 connection between my XP and my Debian), so the cards are not an issue.

The second thing I tried is to change the eth0 configuration to static by copying the parameters I got from the DHCP with my WinXP, but it doesn't seem to work any better.

I also tried to configure my XP to be a gateway for my Debian, with no success.

Basically, nothing seems to go out of my local network whatever I do.

Does anyone have a clue or tip ?

192.168.0.247

looks like a LAN ip, I doubt your ISP will assign multiple IP's to you unless you pay for it.

you need to configure the machine that has the cable modem attached to it as the gateway to to the other computer.

Absolutly, this is a lan ip, that's what makes me think that I didn't get any information from my dhcp.

The modem is attached directly to the Debian box !

dumb question. Did you post the IP for the correct card? If you have 1 card connected to the modem and one to the XP machine, then you have 2 cards. Which card is eth0? The modem card or the XP card?

if ifconfig doesn't show 2 network cards (lo is not a network card) then we need to make the other appear before we can do anything.

There is only one nic in my debian box, but there are two on the XP. I had to change the RJ45 cables configuration to make the tests :

1-
Debian --- Modem --- Internet

2-
Debian --- XP --- Modem --- Internet


But the problem is solved now ... I feel so stupid ... The cable modem had to be reset (electrically) before I could plug it from a box to the other. I was always starting on XP, checking forums, doing searches on google, then moving the modem to the Debian.
I have also been able to connect to the internet via configuration 2, I don't know why I failed yesterday.

It could be because the modem gives the ethernet card's mac adress to my isp when it connects ?
