I have a Lenovo T60 with Ubuntu 10.04 connected with a cross-over cable to a Dell Vostro 1400, also running Ubuntu 10.04. My internet is coming into the Lenovo through an external wireless antennae, and I want to share the internet with the Dell.
On the Lenovo: eth0 connection has IPv4 Settings 'Shared to other computers' I can ping the Dell (10.42.43.10) successfully I can use mtr to trace to www.google.com successfully
On the Dell: eth0 connection has IPv4 Settings 'Automatic DHCP' I can ping the Lenovo (10.42.43.1) successfully when I use mtr to trace to www.google.com, I can only reach 10.42.43.1
I must be missing some setting, but cannot see what it is; can anyone help me?
