Colin:

thanks for the reply. What I don't know how to do is grab the IP from
DHCP. I did in fact do most of the original setup from the shell, but as
I look at the configuration in LinuxConf, the mapping of the second
interface to the gateway looks like its a simple correspondence -
something like 192.168.0.1 -> nnn.nnn.nnn.nnn. where the second IP is
the old static address.

Any guidance on how that second IP can be dynamically looked up from
DHCP? Is this a bit of shell magic or can it be done in LinuxConf...?
(BTW, the Linux box is not currently connected to anything - I'm doing
this on my OS X box which is directly connected using PPPoE. The plan is
to get it running with a hub on the second interface...)
