ifup eth2, to bring up your eth2 nic.
then try route -n or netstat -r again.
So far it shows that eth2 is not up.
After ifup, try <ifconfig -a> to see the interfaces that are setup.
I using MDK 10.1 as well
edit......
Sorry about the eth2 stuff I thought you were setting up a gateway,
Do you have iptables running? if youre not on the web, you wont need it.
But just disable it in the <configure my computer-system-services> no need to remove it.
Ive found it can cause probs when running a firewall script at the same time.
And I found that I could ping ok after disabling it.
