ping -I 192.168.1.2 192.168.1.14 produces "host unreachable".
I've tried 2 different NICs. I suspect the problem is not dead NICs but perhaps something I need to do differently or additionally. I've setup the hosts file with both NICs listed (and tried it with only eth1's address listed - 192.168.1.2) I'm not quite sure what else to do.
Thanks, Don

Hi Don
Stan Glasoe has picked up the issue about the subnets. I'll chip in with this:
If you have 2 NICS, you either DO or DON'T want them on the same subnet according to what you want to do, there is no option. In your case, it seems that you want to use eth1 for your own LAN and eth0/dsl0 as your external connection, in which case [no option], eth0 and eth1 must be on different subnets, to provide separation of internal and external traffic.
I am not familiar with how to configure the eth0/dsl0 interface, because I use a router, but there should be no difference between single machine use configuration and configuration for the single machine to act as router for the whole LAN. So, leave aside eth1 for the moment, just get eth0/dsl0 working as a standalone internet setup on the one machine.
If the DSL were not working with eth0, you wouldn't likely be able to post to the list until tomorrow night. :) eth0 is fine, I just need eth1 working with the internal LAN. So I'll finish working with Stan's message and report back in a bit. I didn't think about using different subnets.
When this works, go with what Stan says about separate subnets, and work on eth1. The machine with the 2 interfaces is then a router, which must have IP forwarding turned on [YaST2 -> Network Devices -> Network Card -> Change [already configured devices] -> edit -> routing -> enable IP forwarding].
After this, you'll need to set up your LAN clients to access the internet, which means pointing them at your machine as gateway or router and sorting out DNS.
Opening the LAN to internet access will definitely come a little later.
