Sorry Folks,
I typed it by hand  output of the commands, duh?! Mistyped IP one ne2 in my
e-mail.Accept my appologies..
Okay correction
IP for ne2 192.168.0.4
IP for ne3 192.168.0.5
It's going to be a GATEWAY, but for simplicity let's look at it as a regular
workstation with 2 NIC's
Connected to a switch. While ne2 is working, and ne3 is not.
Sorry for my mistype.
Thanks,
So Suggestions anyone?
