I'm assuming your modem takes care of the connection and just gives you 
an internal IP address which you set to the gateway? or do you need to 
run PPPoE or some other protocol manually?

  Ed,

it seems that I can't ping the Ethernet modem when using SMP 
kernel(destination unreachable), if I connet to ist internal webpage I 
get a message of no routing.
I have iptables running: and everything is o.k on standard kernel!!!
What is happening???
