ok, things are very exciting :)

I'm going with the diagram at
<http://www.tldp.org/HOWTO/Masquerading-Simple-HOWTO/intro.html>,
except that the external IP should be dynamic for my setup
because that's how the ISP has things arranged.

arrakis eth0	built-in	DHCP
arrakis eth1	D-Link		192.168.0.1
caladan eth	3-Com		192.168.0.2

so, right now I'm basically just reading up on this :)
