That's what I initially did. I just entered two of the @Home NS IP
addresses. But when the debian installer was attempting to download the
base files, it could not resolve http.us.debian.org and failed.

I was using the latest (I think) Debian 2.2r1 boot floppies.

I am not that familiar with IPChains or IPMasquerading right now. So
ever if there was something in there, I wouldn't notice it. Is there a
way to setup IPChains and IPMasquerading to allow any and every type of
traffic ? That would at least allow me to get my second box up and
running. I could then go back and properly configure IPChains and
IPMasquerading.
