well, I don't know why it works, but it does :)

I pinged caladan from the arrakis D-Link NIC with the following
setup:

I have no idea why that works, but it does :)


anyhow, I'm now satisfied that the D-Link NIC works under
linux.  I've already satisfied myself that the built-in
NIC works under linux.

I'm off to setup masquerading, as per
http://www.tldp.org/HOWTO/Masquerading-Simple-HOWTO/intro.html>.
The only wrinkle is that I'm using an asus wl-330g w-fi
network adapter,
<http://usa.asus.com/prog/spec.asp?m=WL-330g&langs=09>,
and while it can be configured from linux it's easier
to configure it from windows 2000, since arrakis is dual
boot.

so, I'll configure the asus adapter for arrakis from
windows 2000.  The adapter, I assume, will have to
connect to the D-Link NIC because that's the NIC
it connects to under windows.

Anyhow, thank you for the help with this thread and
many previous :)
