[lug] two NIC's but only one for Internet access

[Thomas DiGennaro]

I have several computers running Ubuntu 9 or 10, and they each have two
network cards.

One card is connected to my router (and cable modem) for access to the
Internet.

One card is connected to another router, for use only as a LAN for
development embedded systems.

 

How do I configure the network so that only one card (say "eth0") is used
for Internet access?  

 

I find that when I connect "eth1" to its router, Internet access disappears
since I suspect that eth1 is being used, but it's not connected to the
Internet of course.

 

Thanks.
