Configuring Network settings in Darwin x86

Hey all , i just set up a new x86 darwin 6.0.1 machine, and all seems to be going well, but i cant figure out how to get the internet running on the bloody thing. This is my first dive into the Unix/Linux World, save OS X, but the GUI of that is more than forgiving, so this is quite the leap foward.

I am running the box behing a linksys router, and the machine is showing up in teh DHCP table, so i knwo the router is seeing the computer.

I edited the /etc/iftab to set the en0 to -DHCP- and rebooted a couple of times, but still nothign.

Are there any other settings i should try changing? iftab was on -Automatic- by default, and it still didnt work then..

Thanks in advance.
