Big picture.

10 xp machines, 30 Ubuntu systems running 8.04 as well as 8.10. Working very well. At present xp machines will access internet. Ubuntu hook up to network. Pings in network only. Will not ping out side. I am using a wrt54gl router with dd-wrt sp1. Cable Modem. The Xp machines are well.

Ubuntu will not browse or else access internet. Can't update. Help me please.
