Yes, I am putting together a firewall.  I know they will eventually be
on different subnets, but I attempted to just get the thing to come up
properly, therefore assigned it an ip on the same subnet.  I've since
changed it to a different subnet, but I still get the same error
'unknown host' from ifconfig.

I'm currently using ipchains and forwarding to permit multiple machines
access to my single internet connnection.

I've read the book 'Linux Firewalls' and been studying 'Building
Internet Firewalls' and 'Maximum Linux Security' as well.  Hasn't made
me an expert in this area yet though. :(

Just testing the card availability at this time.  Assigning it an ip
from a different subnet didn't make any difference.
