That was exactly it!! I actually figured it out last night. why the f*ck haven't they told me that, it could have saved ma so much time.
I've installed the box at least 3 times during the last day and a half. Couple of ubuntu servers, one slackware...but the box just wouldn't
get the ip form DHCP since the first machine I plug in was my XP laptop - I did it for a test when the guy form the provider was at my place.
First, before ordering internet from them, I insisted that the modem/router needs to be capable of working in bridge mode - they said: 'no problem'. The modem/router that they (provider) brought with them couldn't go into bridge mode - I spent at least 3 hours with him trying things out, talking to his colleagues on the phone - finally they found someone who actually understood what I was talking about. He suggested I take this cheaper modem that has ONLY bridge mode. I told him about my setup and everything, he really could have told me about modem locking to a first PC MAC.
Anyway, the problem was never in my box, but in modem itself. As soon as I turn the power of and on again, the box got it's IP right away.
