3 nics, connect to internet, share to local net, and connect to local net. Not workin


Hi,

I have a Dell PowerEdge 1650 server with 3 NICs in it.
I am trying to use one NIC (eth0) to connect to the internet,
the second NIC (eth1) to share the internet connection to a LAN,
and the third NIC (eth2) to connect to the LAN.

It is running Ubuntu server 8.10

The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.

My main goal is to be able to share files from the server to computers on the LAN.
The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.

I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing.
I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file.
The man file is incomplete, and everything seems to point back to the man file.


If you need any more info, let me know.

Thanks
Anson

That was me just trying to make things more complicated than they really are . . .

I set it up just using the two nics, and the server is visible on the network when the connection is shared.
I had thought that the server wouldn't show up, but hey, it's a learning process. I'm getting better, I promise

I suppose I should have tried that before posting here . . .
Thanks for taking the time to help though.
