man iptables did not get me very far towards actually setting up
something on the router box. Any pointers on what I need to do?

I think you mean /etc/network/interfaces. What needs to be done in
this file on each machine? Here is the router box's current interfaces
file:
auto lo
iface lo inet loopback
iface eth2 inet dhcp
name Wireless LAN card
wireless_essid any
wireless_key 1A2B-3C4D-5E6F-1A2B-3C4D-5E6F-1A
auto eth2
The parasite laptop is just configured to use eth0 to connect to the
internet at the moment.
