The reason is that you don't have eth1. You have only one NIC in there,
right? Then eth1 is what you could call "virtual interface", hehe. The one
that's physically connected with your winbox is eth0, and you need to
configure two addresses for it. Now, I've known for a long time that linux
can have more IP's on the same NIC, but I never needed it, didn't know how
it's done, and found out that this isn't documented either. ifconfig
manpage didn't help, google did. What you need is:
ifconfig eth0:1 10.0.0.2 up
The description I found said: ifconfig IF:N <ip-address> up/down, where IF
is clearly the interface name, and N a number between 1 and 255, meaning
that you can switch 256 IP's on one interface on and off as you please,
yipee. Don't know why, but this newly discovered fact gives me a strange
pleasure.
Hope this helps
Cheers
