Now that I've got NAT figured out on my linux firewall, I'm encountering a
slight nuisance. 

(I'm using non-routeables in this example on purpose...)

Packets for my subnet get routed to my Cisco 678 (DSL Router) by my ISP.  My
Cisco has the IP address of 172.16.0.1.   Behind the Cisco is my firewall with
an address of 172.16.0.2.  Behind the firewall I've got a network in ten-space.

I want to set up NAT for the 176.16.0.0/16 network on my linux firewall, but
this doesn't work without configuring some NAT on the Cisco.  I need to make it
so that the Cisco sends all the packets for 176.16.0.0/16 to 176.16.0.2 (so it
can handle all the NAT), but I can't figure out *how*.

I can't seem to find any helpful documentation on the web, and I'm sure it
should be able to be done.  Any suggestions?
