Hi Greg,
You need to set up your network so that everything's connected to
everything else...get both Macs and the cable box Ethernetted together.
That would be normally accomplished using a hub, but I guess if I'm reading
you correctly, your one ethernet card can act as a hub? Then, you want to
set up the NetBSD box to have 2 separate IP addresses. One would be the
x.x.x.41 from the cable co. The other would be from the RFC 1918 ranges for
private addresses (I'll use 192.168.1.1). You'll want to set the other Mac
to use another private IP address (192.168.1.2). Then you'll want to set up
the ipfilter to filter whether info is going just within the 192.168 or
within the rest of the Internet's ranges. The way that you set up the
NetBSD box to have both IP addies is to use both ifconfig and ifalias.

HTH
